Our most important product is customer satisfaction Comprehensive solutions from one source

Ensuring we have satisfied customers is our highest priority. Our entire business operations are focused on achieving this which results in our strict orientation on deriving maximum customer benefits. We want you to benefit directly from our products and services particularly from the close cooperation with us and have a real competitive edge in the market – both technically as well as economically.

Because we know our customers, their tough day-to-day working environment and their competition, it is always a question of ensuring that our products and services find solutions to problems, simplify and accelerate operations, enhance on-site safety levels and, in particular, help reduce time and costs. Therefore, around 1,300 PERI engineers worldwide are hard at work every day in order to develop efficient solutions and implementation plans to realize our customers projects. And it is not unusual that new products or additional services are generated from such individual solutions. Parallel to this, PERI research activities constantly strive to develop innovative technologies and products that meet the needs of our customers around the world.

As partner at the side of our customers jointly implementing the best and most cost-effective formwork and scaffolding solution in each case thus strengthening the competitiveness of our customers over the long term – and we work hard on this with total conviction.

An important contribution for ensuring the satisfaction of our customers: the PERI performance price Our engineers take into consideration the total cost of materials and working hours in every product development – we call this the “performance price”. Fact is that if material costs are reduced and valuable planning, working, crane or machine time can be saved, then the investment quickly pays for itself and the price is put into perspective again.

Products and systems that successfully prove themselves in the market Groundbreaking formwork and scaffolding technology which continues to set standards in the industry

The basic requirements of our developments is to ensure faster and safer working operations. PERI products are therefore designed so that they provide users and construction companies with advantages regarding the handling along with workload reductions, enhanced safety as well as cost and personnel savings. We thereby attach great importance to minimizing the number of individual components for system assemblies because this has a positive day-to-day effect: as a result, every use is faster and easier, logistics requirements are reduced, search times on the construction site are a thing of the past – to name just a few effects.

Innovative construction, intelligently- configured mechanical systems, high quality and durability are likewise given requirements for PERI engineers. Wherever possible, we develop our systems for the widest possible range of applications. As a result, this allows maximum material utilization and avoids unused stocks of materials. Where necessary, we complement system components for very special applications so that expensive, project-specific constructions can be dispensed with. Thus, PERI solutions increase the economic efficiency, very often for all the construction processes.

Proof that we are on the right track with this approach is the fact that PERI has always set standards in the market with its innovations and that PERI systems have established themselves worldwide.

“We develop new products for applications with which we see rationalization potential with a real future. In this way, efficient system equipment with practical details is developed which maintain a strong position in the market over many years.”

Innovations to meet every customer requirement Focusing on user benefits

DUO Universal Formwork is in many ways a typical PERI product. Typical because the DUO system has taken on board customer requirements from various markets which has resulted in an extremely lightweight, easy-to-handle and versatile formwork. With a formwork manufactured from robust technopolymer, the virtually tool-free assembly along with the possible application for walls, foundations, columns and slabs, we have once again met these requirements with this special new development.

The application of polymer products has been the focus of PERI materials research for a number of years now. All development actitivies are aimed at the specific use of these polymers in formwork and scaffolding technology. Since 1995, for example, the plastic rack of the SKYDECK main beam has proven itself countless times, and is made of an engineering grade plastic. Furthermore, our portfolio has included for quite some time simple Slab Stopend Angles and other accessories made of this material.

The use of different materials is nothing new for us. We were one of the first manufacturers in favour of utilizing aluminium in formwork and scaffolding technology. In spite of some initial concerns of the market, this material has now become indispensable due to its many advantages.

Developments in scaffolding technology The focus for a new type of scaffolding system was on combining the speed inherent in 3D scaffolding with the flexibility of modular scaffolding, and maintain compliance with current as well as future safety regulations.

This has resulted in PERI UP Easy with the special frame which provides the highest level of safety. Thanks to the ingenuously designed rosette, the Facade Scaffolding is compatible with the PERI UP Flex Modular Scaffolding. This provides extended application possibilities for more complex scaffolding tasks.

First-class quality is standard at PERI You can count on it

We endeavour to produce and deliver consistently high quality on a sustained basis. Therefore, we continually invest in modern production processes and inspection procedures to become even better. Already during product development phase, we subject the components to a wide range of tests in order to get the most out of them ready for the serial production. This includes, among other things, longevity tests in salt baths or torsion tests on the individual components. Thus, we ensure that PERI systems are suitable for tough everyday operations on the construction site as well as being considered reliable enough.

The entire process of the subsequent serial production is subject to continuous quality assurance which is clearly defined and has been repeatedly certified, from purchase through to delivery. This means we can provide the promised quality of PERI formwork and scaffolding systems.

Here, too, the results are repeatedly placed under continuing review. And naturally we always use new findings to implement further improvements. For example, an additional cavity sealing with active corrosion protection was developed for the MAXIMO Panel Formwork and integrated in the production process which, in turn, has further increased the durability of our innovative wall formwork.

The wide range of PERI development and production processes include load tests, durability tests as well as continuous quality control. Furthermore, certification from external testing institutes and organisations attest to the high quality échafaudages échafaudages échafaudages échafaudages échafaudages échafaudages échafaudages of the PERI products.

“Development, production and quality assurance work hand in hand at our company. Highly qualified personnel and the very latest production and testing procedures ensure long-lasting products.”

Sustainability as a main principle Taking active responsibility

Future viability as well as ecological and economic sustainability have a high priority for all our company activities. The focal point is geared towards the best material utilization as early as the development phase while the load-optimized design of the PERI systems and system components ensures economical use of materials. The selection of raw materials and their procurement takes place at PERI in terms of ecological sustainability. Therefore, for example, the wood for our plywood formliners originates as far as possible from certified, sustainably-managed forests. Our procurement processes are an integral part of the quality management system and we take into consideration and optimize current and future environmental costs. Thereby, the substitution of hazardous or harmful substances has also been company strategy at PERI for decades.

The design of the MULTIPROP Prop exemplifies optimized material utilization: the shape guarantees a high load-bearing capacity of the prop with minimum material requirements.

In the production, new technologies and efficient processes ensure resource-saving manufacturing and best product quality. This guarantees a high number of repeat uses and a long service life of the PERI systems which, in turn, positively influences the consumption of resources. However, if the demanding daily wear and tear does result in damage being caused, the PERI material can be professionally refurbished in our logistics centres. Delivery and construction site logistics are also optimized regarding shipping volumes and transportation routes. Strategically-positioned sites guarantee short delivery distances whereby transportation is also continuously optimised through an intelligent logistics network.

PERI systems have been designed to provide a long service life. With panel formwork, for example, even badly damaged elements can to be used countless more times after being repaired and fitted with a new formliner.

Last but not least as a family-owned company, we are in principle oriented towards maintaining sustainability. Future-oriented actions based on economic, social and environmental sustainability has always been a central element of the PERI culture. The PERI company management has thereby acted with a far-sighted approach and implemented a long-term strategy – beginning with the founding of new PERI locations and the comprehensive training programme for PERI employees through to the strategic development of new markets and business areas.

The DUO Universal Formwork components are made of a technopolymer in injection moulds which means no waste is generated. Used material can be used to manufacture new products.

A symbol of sustainability at PERI: wood chips which occur as a waste product in the girder production feed our biomass heat and power plant at the company headquarters in Weissenhorn. It generates heat and electricity for the entire location as well as neighbouring households.

Engineering at the very highest level High professional competence and extensive experience of providing customized solutions

PERI engineers plan and design formwork and scaffolding solutions while taking into account the technical requirements, boundary conditions during the application as well as respective individual customer requirements. This results in optimized solutions for each project Task – very often during the tendering phase. Furthermore, PERI also provides the required technical documentation – from implementation drawings through to verifiable static calculations. Goal of the PERI engineers is always ensuring process optimization with the objective of reducing both execution times and costs.

In this connection, we are also intensively involved with the technology of Building Information Modeling (BIM). In the process, the systems are used for building information management during the planning and implementation phases which facilitates cross- company communication as well as over different locations. The goal of all PERI developments is the complete integration of formwork and scaffolding solutions in future BIM simulations. In the future, our engineers want to fully exploit the potential of 5-dimensional planning in the execution of construction work together with our customers.

The high level of expertise found in the international PERI application technology has been achieved through intense cooperation, close networking and continuous training of our engineers worldwide. In this way, we also ensure that the know-how in our company along with all the acquired international experience really does benefit each of our customers for every project regardless of its size.

“The thinking in processes for optimizing construction progress is a matter of course for our engineers. In addition to the technical requirements, they always take into account safety considerations and economic efficiency of the execution.”

The following PERI formwork and scaffolding systems, as well as components, show an overview of the international PERI product portfolio. The appropriate programme for meeting the specific require ments of a market is defined by the respective PERI national company.

Wall Formwork originally comprised of squared timbers and boards. This has resulted in modular systems which are characterized by a wide range of applications and long service life. Based on the respective construction, a distinction is made be tween girder wall formwork and panel formwork. With the girder wall formwork, form work girders support the formlining while steel profiles serve as walers. Itcan be individually adapted to accom modate complex shapes and high loads. In particular, architectural concrete structures with high requirements for surfaces and anchor patterns can often only be efficiently realized with girder wall formwork.

Panel formwork with frames made of steel or aluminium has considerably fewer individual components. Fixed panel sizes including formlining, sys tem components for connections and wall connections, as well as other site-compliant detailed solutions, facili tate fast forming of large areas. In addi tion, the possibility to move larger units by crane accelerates formworking operations.

MAXIMO Panel Formwork The particularly cost-effective system with MX tie technology and simultaneously providing the best concrete finish

Developed by PERI, the MX tie tech nology with one-sided tie installation greatly accelerates formworking opera tions. At the same time, MAXIMO is significantly faster than conventional panel formwork despite the lower site personnel requirements. Due to the innovative tie technology and optimized number of tie points, working time val ues for the system are verifiably up to 50% less. In addition, the centrally- arranged tie points result in a regular joint and tie pattern both horizontally and vertically.

Wall Formwork

Faster tie installation through the one-sided tie technology without spacer tubes and cones Minimum of anchors through the optimized tie point arrangement Improved concrete finish through the neat joint and tie arrange ment The specially-developed MX Tie is installed from one side only and is used without spacer tubes and cones. This means material and working time savings.

The wall thickness can be easily adjusted on the anchor by means of a cotter pin. The usual wall thicknesses are indicated through markings on the tie rod.

Slab Formwork essentially consists of a horizontal load-bearing structure which supports the formlining and transfers the forces into the shoring.

section. Tables provide a very high level of safety in particular at the slab edges, and ensure very fast shuttering times for large-sized areas.

For girder slab formwork, wooden or aluminum girders are crosswise- mounted and covered with formlining of choice. This construction allows easy adjustment to accommodate different loads and ground plan geometries.

Modern modular slab formwork systems comprised of panels or girder grids facilitate fast forming operations due to a minimum of individual components and a systematic assembly sequence. For filler areas, complementary system components provide quick and reliable implementation solutions.

Large-sized slab tables are prefabricated based on the same principle and then delivered to the construction site. After use, the slab tables are transported below the slab to a position which can be reached with the crane and, from there, moved to the new concreting

GRIDFLEX Grid Element Slab Formwork The slab formwork for simple assembly and a high level of working safety

Slab Formwork

GRIDFLEX is used for constructing residential and multi-storey buildings. The standard element weighs only 20 kg, and is pushed upwards into position by means of the Shuttering Aid GF with site personnel safely positioned on the slab below. Slab props are subsequently hooked in and vertically aligned. On the now accessible girder grid, the formlining of choice can be installed. The recurring systematic assembly sequence ensures fast forming operations. Safe shuttering procedure by swivelling the elements upwards with site personnel positioned on the slab below Simple working operations with one standard and two compensation elements as well as the GRIDFLEX Prop Head Filler areas are quickly closed through a simple change of direction of the elements along with the use of transverse and longitudinal infills

The different colours of the powder coating indicate the function of the slab elements. This simplifies both the forming and logistical operations.

The assembly sequence is very simple: hook-in element, push into position with the shuttering aid, attach slab prop and position vertically.

GRIDFLEX has received a number of awards as an innovative and particularly safe system.

After the assembly process has taken place, the closed girder grid can be safely accessed for installing the formlining.

MULTIFLEX can be adapted to suit all ground plans. The overlapping of the slab girders and change of direction of the main beams ensure maximum flexibility.

The main components of the MULTIFLEX are the VT 20K or GT 24 Formwork Girders. As the main and cross beams, their position and spacing as well as the formlining can be freely selected, MULTIFLEX provides maximum flexibility for a wide range of requirements. If the high load-bearing GT 24 Formwork Girders are used, large spans for the main and cross beams can be realized. MULTIFLEX is therefore the ideal solution for complicated ground plans, slabs with offsets or integrated downstand beams, as well as forming operations in confined spaces.

Optimized use of materials through any combination of GT 24 and VT 20K Formwork Girders as well as a freely selectable girder arrangement

The Flexclip is available for three different girder combinations. The additional component ensures tilt-resistant connections of the girders without any nailing.

The choice of girder is based on project-specific requirements: the GT 24 Lattice Girder allows large spans and thus reduces the number of parts to be moved. The VT 20K Solid Web Girder is the cost-effective solution for smaller slab thicknesses.

For all ground plans through the variable positioning of the girders – also polygonally or overlapping For all surface requirements with freely selectable formlining for the stipulated quality and adaptable to suit the required joint arrangement

The use of the GT 24 Latice Girder as a twin main beam, in connection with PERI UP Flex Shoring, facilitates the transfer of heavy loads over great heights.

With the PERI MULTIFLEX Configurator app, beam and prop spacings can be optimized quickly and easily.

VARIODECK is quickly moved into the next storey in each case with a single crane lift. By means of the swivel head, the 4 props can be easily folded in the longitudinal direction of the table, e.g. for moving under beams. Quickly ready for use through the provision of pre-assembled tables – during assembly, only the lower part of the swivel head must be attached to the slab prop

The VARIODECK Table provides a quick and safe solution for slab edge areas in particular.

Due to the low overall height of only 36 cm, 20% less transportation and storage volumes are required than for slab tables with main beams consisting of 20" wooden girders.

High load-bearing capacity with longitudinal-positioned steel walers which allow large cantilevers or can accommodate heavy prefabricated parts Flexibly adaptable by continuously moving the Table Swivel Head ± 15 cm

The Table Head TK securely connects the props and slab table together. It is the cost-effective alternative to the Table Swivel Head.

The project-specific planning facilitates very cost-effective slab tables as the static load of the individual components is optimized.

For large slab thicknesses and high loads, high load-bearing GT 24 Formwork Girders are used.

For higher geometric or static requirements, slabs at great heights as well as residual areas, project-specific slab tables are planned and assembled. Depending on requirements, swivelling Table Heads or simple, rigid connections can be used. In particular, the support of the slab tables can be designed extremely flexibly – from simple slab props through to shoring towers with heights of more than 20 m.

Accessories for Slab Tables Practice-oriented equipment for ensuring safe moving procedures

Slab Formwork

For moving the slab tables, the PERI portfolio includes features a range of equipment. For fast transport into the next storey, PERI Transportation Forks are used. The transportation forks are always in a horizontal position when not in use as well as when transporting a slab table. The Table Lift allows fast moving of tables throughout the storey. The flexible and easy to steer equipment is fitted with an electric drive and can also be used in confined spaces. Alternatively, slab tables can be aligned and horizontally transported with the cost-effective table trolley. The Stripping Cart serves as movable working scaffold with a standing height of maximum 4.65 m.

The crane pulls the table horizontally out of the building with the help of the lifting mechanism and the single roller. Workers are not required to stand on the table at any time.

Universal Formwork stands for a system formwork whereby the same components can be used for a range of applications – these therefore can be used universally for the forming of horizontal and vertical structural elements. The system components are optimized in terms of their multiple usage for the various applications. As a result, the investment costs for universal formwork are significantly lower than that of several comparable formwork systems for these applications.

life-cycle perspective: the user works more efficiently through always using the same system, the demand on storage area decreases and transportation costs are significantly reduced.

In addition, the small number of different system components simplifies the requirements and material requisition on site. The benefits become even more evident when viewed from a

DUO The universal lightweight formwork for walls, columns and slabs

Universal Formwork

DUO can be used both for foundations, walls and columns as well as for slabs and beams. The system is characterized by the extremely simple handling and the minimum number of different system components. Almost all operations with DUO can be carried out without tools while the working steps are very easy to understand. Even those less experienced users of system formwork can work quickly and efficiently with DUO. New is not only the concept but also, in particular, the material used. Both the Panels – including the formwork – and the DUO accessories are made of the innovative Polytech composite material. Due to the low weight, no crane is required for assembly operations.

■■ Particularly

The replacement formlining can be mounted by hand using only a few screws – also on the construction site and without any special tools.

Universally applicable Flexible forming of walls, columns and slabs using only one system Ergonomic in all respects Low weight, crane-free handling and intuitive application Easy replacement of formlining Quick repair with just a few screws – without requiring any special skills

Due to the manageable dimensions of the DUO panels, these are also ideally suited for the construction of foundations.

DUO is made of Polytech material, that provides permanent protection against moisture as well as being very light and highly flexible in terms of product design.

Individual Formwork stands for solutions that PERI individually plans and pre-assembles. In contrast to so-called project-specific solutions, what is meant here is formwork which undergoes stationary prefabrication before use. This is then the case if production on the construction site is not possible; either due to the very complex design or because special tools and machines are required. The prefabricated formwork elements are subsequently quickly and easily connected on the jobsite to produce the complete formwork.

are re-used after the free-form formwork has been dismantled. In addition, individual formwork is also used for monolithic construction, when identical building structures are to be realized in large quantities, for example, social housing projects. In the process, always using the same system ensures extremely short assembly times and fast construction progress.

With so-called free-form formwork, the highest architectural demands on geometries and surfaces can be rea lized. Such unique pieces are quite cost-effective due to the high proportion of standard elements, e.g. formwork girders and steel walers, which

Freeform Formwork Precision-made for an individual design

Individual Formwork

For the construction of complex, multicurved reinforced concrete components, PERI provides customized freeform formwork. Based on a 3D building model with so-called freeform surfaces, the formwork units are individually produced in the PERI formwork assembly facilities. Assembling the individual elements on the construction site is similar to system formwork. Statically load-bearing elements are usually based on VARIO GT 24 Girder Wall Formwork. Hence, many individual components can be further used after project completion. Custom manufactured On the basis of a 3D model, precision manufactured under optimum conditions in the stationary PERI formwork construction facility.

Shoring Systems are temporary structural elements which serve to transfer loads during the various stages of construction. They support, for example, formwork until the concrete has reached its load-bearing capacity, or transfer loads from components and equipment during the construction, maintenance or demolition of structural works. The requirements placed on shoring systems are diverse; load-carrying capacity, assembly height and adaptability are likewise important criteria as individual component weights as well as the possibility of integrating working areas and access means.

t owers or slab tables. Shoring towers can also be realized using individual frames which are easily put together. Enormous flexibility is offered through the use of modular scaffolding, ranging from a simple shoring tower through to complex spatial shoring, and can be adapted to suit virtually any geometry as well as different loads.

Props made of steel or aluminium are used which are often connected by means of frames to form shoring

PEP Ergo Tubular Steel Slab Props The galvanized tubular steel slab prop with up to 50 kN load-bearing capacity

PEP Ergo Props are mainly used for supporting slab formwork. Numerous practical features ensure fast and safe handling – this includes, for example, the trendsetting Adjusting Nut or the ergonomic G-Hook which cannot jam. The galvanization guarantees a long service life. However, if a prop is damaged during the tough everyday working operations on the jobsite, the inner and outer tubes can be replaced separately.

Working Scaffolds

are temporary constructions. They serve to create higher-positioned working areas for construction site activities, on buildings as well as on industrial facilities. In addition, they ensure that working areas can be safely accessed.

health and safety legislation and standards regulate the requirements placed on a scaffold with respect to assembly, bracing, anchoring and sufficient load-bearing capacity for the various areas of application.

Modular scaffolding systems guarantee fast erection times, high load-bearing capacities and safety levels for assembly and dismantling as well as during use. While frame scaffolding is aimed at ensuring a high tempo for 3D scaffolding construction, modular scaffolding with nodal points for connecting ledgers, brackets and other components provides greater flexibility for geometrical adjustments. In the process, country-specific occupational

Scaffolding is also named after its area of application. For work operations on the front of a building, narrow facade scaffolding is used. On construction sites, working platforms are normally utilized as well as reinforcement scaffold. Industrial scaffolding is the name given for providing access and work platforms on industrial installations.

PERI UP Flex Suspended Scaffolds Movable scaffolding solutions

PERI UP Flex Bridging Working platforms up to 10.00 m long with the Lattice Beam ULS

For movable-type solutions, Standards together with the Trolley UFS 20 can be attached to I-shaped steel profiles. The Trolley carries loads of up to 19.7 kN and allows entire platforms to be moved e.g. on the underside of oil platforms or bridges. For project-specific solutions, rentable steel components from the VARIOKIT Engineering Construction Kit or other PERI formwork systems for the supporting structure are often used.

With the PERI UP Flex Lattice Beam ULS, bridging spans up to 10.00 m long can be cost-effectively realized. The beam consists of 5 easy-to-handle individual components with a maximum length of 1.50 m and maximum weight of 15.4 kg. The beam length can be adjusted in 25 cm increments. The proven UDG Decks can be directly mounted on the upper chords of the beam. Ideally suited for refurbishment projects due to the compact dimensions and low weight, can also be used in confined spaces and access via manholes

Temporary Access must fulfil different requirements regarding geometries and maximum loads which are defined, in particular, by the respective area of application and user groups. Basically, a distinction is made between access to higher-positioned working areas and temporary access means for public areas. Access solutions for working areas must be adapted primarily to suit the number of users as well as the loads incurred. Authorised users are all those involved in the construction project, i.e. persons in appropriate working clothes with suitable protection equipment.

110

Users of public stairs, however, are all persons who use areas open to the general public – from infants to frail elderly people. In addition, large gatherings of people can be expected. Accordingly, specific requirements for flight widths, execution of intermediate landings and safety equipment – among other things – are to be taken into consideration.

Protection Scaffold secures construction personnel against falling as well as unfavourable weather conditions. Furthermore, protection scaffold is frequently installed in order to protect site workers underneath or the flow of traffic from falling components or objects. In accordance with the different potential risks and dangers, there is a range of options available, for example, weather protection roofs or scaffold constructions complete with protective nets.

118

Detailed requirements, such as the geometry, load-bearing capacity or roof area inclination, are normally defined in corresponding occupational health and safety legislation and standards. System solutions take into account these requirements as far as possible. Other project-specific needs are implemented using individual planning solutions.

Climbing Systems

124

are used for the construction of vertical as well as inclined structural elements at great heights, e.g. high-rise building walls, bridge piers and dams. In addition to simple scaffold platforms, there are other different climbing systems whereby brackets, platforms and formwork are connected to form securely mounted units. These climbing units can be lifted as one unit to the next concreting section after striking has taken place.

while dedicated climbing shoes provide safe and secure anchorage on the building. Apart from systems with integrated hydraulics, rail-climbed systems are also available which operate using mobile self-climbing devices.

With the traditional crane-climbed formwork, units are moved by crane and attached to climbing anchors which have been concreted in advance. If a hydraulic climbing device lifts the units to the next storey, then this is called self-climbing formwork. For this crane- independent variant, the climbing unit is guided mostly by means of rails

Climbing protection panels, which serve as a wind shield and anti-fall protection, complete the product portfolio for ensuring safe and comfortable working conditions at great heights.

For different building shapes and tasks, optimized system variants have also been developed: climbing systems for facade areas, building cores and shafts as well as inclined bridge pylons.

Climbing Systems

The mobile climbing device allows climbing without a crane. The hydraulic cylinders are mounted on the climbing shoe between the wall and climbing rail.

Foldable runners allow the lateral dismantling of the climbing shoe and simplify the initial assembly.

The RCS combines the advantages of different climbing systems in a modular system and is used as climbing formwork as well as a climbing protection panel. Through the rail-guided climbing, the climbing unit is securely connected to the building at all times which makes the climbing procedure fast and safe also in windy conditions. The units are moved by crane or by means of mobile climbing hydraulics to the next section. RCS is easily adapted to suit jobsite- specific requirements.

■■ Montage

Civil Engineering Systems for tunnel and bridge construction usually feature a combination of shoring and individually adapted formwork. The planning must include structural dimensions, construction method and the entire construction process. In tunnel construction, the geology significantly determines the construction method as well as the construction procedure. This, in turn, determines the requirements for tunnel formwork. The shoring is usually executed in the form of a mobile formwork carriage. For bridges, the geographical boundary conditions determine the construction procedure and thus the formwork solution. Realization of the superstructures can be carried out using shoring constructions, the incremental launching method, steel composite method, or

138

the balanced cantilever method. Parapets are subsequently concreted which have a technical protective function and form the architectural completion of the bridge superstructure. Practical, sophisticated modular construction systems are designed to facilitate cost-effective solutions for the majority of all requirements in civil engineering.

As a rule, multi-storey constructions are characterized by medium-sized down to smaller room units. For walls, columns as well as slabs, the concrete construction fulfils all requirements regarding functionality, cost-effectiveness and design. The slab construction and realization in particular play an important role. In residential construction, basement walls and floor slabs are usually cast in-situ – with individual building forms. Also in living areas, concrete is increasingly being used as a modern design element, very often combined with high architectural concrete requirements.

MAXIMO and QUATTRO guaranteed short construction times for both walls and columns. For forming the walls, the use of the MX Tie Technology in the MAXIMO Panel Formwork – with ties inserted from one side only – meant spacer tubes and cones were not necessary, and thus required no extra man on the opposite side. QUATTRO Column Formwork guaranteed safe working conditions and crane time-savings. It could be moved as a complete unit including the push-pull props, platform and ladder access.

Tobias Knappke Site Manager “Workplace safety has always had the highest priority for us. Thus, the VARIODECK Edge Tables, including the anti-fall protection, as well as the PROKIT Edge Protection was a safe solution for all site personnel involved in the construction work, and also led to a positive overall impression of the jobsite. And with the one-sided MAXIMO tie operations, we could realize the bulk of the reinforced concrete walls in a short construction period.”

Fabio Luis Toldo Project Manager “We opted for the UNO Formwork because the system is simple to use and very user-friendly. After a very short time, the floors could be concreted in regular 3-day cycles; as a result, we are able to stay ahead of the originally planned monthly schedule.”

In Ghana, affordable housing was realized in a very short period of time by means of the monolithic construction method with the UNOHousing Formwork system.

Over 500 complete floors were completed with the UNO Housing Formwork using a monolithic construction method.

176

Formwork planning and fabrication was carried out individually, always adapted to match the respective building geometry. Window and door openings as well as the beams were also integrated in the PERI solution.

The Saglemi Housing Project includes the realization of around 5,000 residential units. In the first phase of construction, 180 apartment blocks comprised of over 1,500 flats were built within a very short time. Each of the 3-storey structures features 6 to 9 apartments, with 40 m² up to 85 m² living space respectively.

The buildings were largely constructed using the monolithic cast in-situ method, i.e. a complete floor with 12 cm thick concrete walls and slabs concreted in one pour. For this, PERI provided the best solution with UNO Housing Formwork as the project-based prefabricated aluminum panels were easy and simple to install, and without the use of a crane. For connecting the elements with the UNO Wall Wedge Coupler as well as anchoring, a hammer and wrench SW19 were sufficient; in addition, the UNO tie technology features single-sided operations. After

hardening, first the walls were stripped followed by the slabs. Altogether, 6 UNO formwork sets were in use in daily jobsite operations, designed for 3 different ground plan versions. After a short familiarization period, the construction crews achieved a regular 3-day cycle which meant 2 complete floors could be concreted every day.

The support provided by the PERI specialists shortened the familiarization phase and accelerated the construction sequence.

Sasol Administration Building, Johannesburg, South Africa Over 200.000 m² floor slabs brought into shape

Housing & Multi-Storey Projects

Timothy Rowbottom Contract Manager “SKYDECK effectively addresses the issues of time, quality and cost. It is extremely versatile and can be adapted to accommodate just about any decking issue.”

The slabs were formed with the help of the SKYDECK system in rapid cycle sequences.

In spite of the complex building geometry, work could be carried out to a large extent with system formwork.

On the building corners, individually planned slab tables suplemented the cantilevered-mounted SKYDECK edge solution.

An extraordinary glass facade encloses the new Sasol company headquarters. With the help of SKYDECK, a 202.000 m² slab area was formed and brought into shaped.

The floor slabs were formed with the SKYDECK Panel Slab Formwork in rapid cycle sequences. Furthermore, both time and costs could be saved by means of the systematic assembly sequence and lightweight elements while dealing with the challenging building geometry. SKYDECK platforms on cantilevered-mounted SLT 375 Main Beams ensured safe working conditions at the slab edges. Closing the infill areas of the partly inclined columns was also carried out with system components. In the area of the building´s acute-angled corners, project-specific slab tables were used with great success.

In addition to detailed formwork planning for the floor slabs, which was individually tailored for each level, implementation solutions for the bridge constructions were also designed. MULTIPROP and PEP Slab Props served as the load-bearing system which could be connected by means of frames to form shoring towers. On the occasion of this major building project with a total construction period of almost 3 years, the contractor extended his existing TRIO portfolio with the SKYDECK system. By precisely matching material deliveries from the PERI rental park to suit the construction process, the on-site material requirements could be a easily adapted and effectively managed the peak demands.

Sandton is the financial and business centre of Johannesburg. It is here that Sasol, the international oil and chemical giant, chose to build their new headquarters. The futuristically designed building provides a state-of-the art working environment for around 7.000 employees, featuring seven basement levels of 114.000 m² and ten upper levels of 88.000 m². The different areas are grouped around a central core and connected to each other by means of bridges.

Contractor Swietelsky Baugesellschaft m.b.H., Hochbau Ost, Grp. Nußdorf o. d. Traisen Field Service PERI Austria, Nußdorf

Using the MAXIMO Panel Formwork and SKYDECK Slab Formwork, the shell construction was completed in only 12 months. The name “villanova” embodies the Italian approach to life, a message conveyed by the new residential complex at the Alanovaplatz which is situated close to the town centre. The villa-like building complex was built on the site of the former brewery. Now, a modern residential building with a total of 100 apartments provides a reminder of the early Roman settlement in what is now the urban district of Schwechat. For forming the reinforced concrete columns, SRS Circular Steel Column Formwork was used – partly in combination with MAXIMO elements.

180

MAXIMO 270 and MAXIMO 330 complemented each other perfectly and, thanks to the MX Tie Technology, provided time-saving operations from one side.

The systematic assembly sequence along with the low individual weights of the SKYDECK accelerated the construction progress.

4 apartment buildings, each with 5 upper floors, are connected by 2 basement levels. The basement walls were realized as far as possible using concrete cast in-situ. For this, MAXIMO Panel Formwork was used as was the 20 cm to 30 cm thick reinforced concrete walls of the upper storeys. The single-sided MX Tie Technology resulted in a reduction of required anchor points along with the simultaneous elimination of spacer tubes and cones, saved valuable construction time from the beginning onwards. This was a

great advantage as only 12 months was scheduled for the shell construction. Consistent with the rapid progress through the use of MAXIMO for the walls, all storey slabs were systematically and therefore effectively formed with the help of SKYDECK. In particular, the logical and clearly specified assembly sequence as well as the simple handling due to the lightweight aluminum components reduced shuttering times. In addition, through the use of the SKYDECK Drophead System, the panels and main beams could be used at an early stage for the next concreting cycle in each case. This allowed cost-savings to be effected along with reductions made regarding on-site material requirements.

The walls of the central cores were formed in advance using VARIO GT 24 whereby the girder wall formwork was climbed with the help of the RCS Rail Climbing System to the next level in each case. Through the use of mobile self-climbing hydraulics, no crane was required here. In addition, climbing operations could still be carried out with RCS even in strong winds as the formwork scaffolding was connected at all times to the building by means of

With the help of LICO Column Formwork, the reinforced concrete columns could also be crane-independently formed. Then, the lightweight, 3 m high elements could easily be assembled and disassembled by hand. For forming the individual storey slabs, use of large-sized slab tables reduced the number of crane lifts required. As a result of the fast operating speed of the RCS Self-Climbing Formwork, the tables were also stripped after only 3days and moved to the next section each time with the transportation fork.

“The PERI slab tables ensured easy striking and moving to the next level. Thanks to the RCS Climbing Formwork, we were also able to climb every third day. This accelerated the concreting work and shortened the cycle sequences for the core walls and floor slabs.”

Skyscrapers and Towers impress through their size and are also increasingly being considered as architectural highlights and characterize the skylines of many cities around the world. Modern-day types of construction and range of methods allow the realisation of sophisticated architectural designs. The use of reliable climbing technology rationalizes work operations and facilitates fast construction progress without any interruptions – weekly cycles can very often be completed much earlier. An integral part of a formwork and scaffolding solution is a project-specific safety concept: with anti-fall protection equipment for all stages of construction, safe construction site operations particularly when working at great heights, protection against wind and weather also when subjected to high wind speeds as well as instructing site personnel at the start and during the building project.

Alon Towers “BSR Center TLV”, Tel Aviv, Israel 3 climbing systems perfectly matched to one another

The RCS Climbing Protection Panel units climbed crane-independently with the help of mobile self-climbing devices to the next floor each time.

quality and safety standards. In addition, the strict construction schedule as well as the limited crane capacity were taken into account.

Alon Towers consists of two symmetrically arranged, 164 m high twin towers. They are part of the new, modern “BSR Center TLV” office complex and define the skyline of Tel Aviv. A special architectural feature is the X-shaped facade design which is perceptible from all sides: both towers taper to the halfway point and then widen again to the top. PERI Israel provided an ideally matched implementation concept on the basis of the ACS and RCS Self-Climbing Systems as well as self-climbing CB Platforms. As a result, the construction crews could work very efficiently also at great heights – protected against the wind and concealed from view as well as being crane and weather-independent. The PERI comprehensive package complete with planning services, on-site support and logistics ensured, in particular, compliance with the high 186

The climbing formwork solution for the building core was a combination of ACS, RCS and CB in connection with VARIO GT 24 Girder Wall Formwork and suspended DOMINO Panel Formwork for subsequently completed intermediate walls. With the decision to construct the core in twin sequential phases in each case, the cycle sequence was adapted to match the execution of time-critical reinforcement work. The circumferential enclosure and anti-fall protection of the top floors of the shell construction in each case was realized with the RCS Climbing Protection Panel, geometrically adapted to suit the forward and reverse-inclined facade as well as being designed for the required change of inclination at heights of almost 80 m. An important part of the PERI Protection Panel solution featured the integrated landing platforms which facilitated temporary material storage and for the moving of loads with the crane.

For forming the oblique-angled building corners – due to the facade inclinations – specially designed corner platforms were used which were based on system equipment.

Due to the 25 cm system grid, the scaffolding could be flexibly adapted to suit the building's geometry with different set-up heights and circular columns at inclined spatial angles as well as increased load concentrations. Furthermore, aluminium flights of stairs integrated in the birdcage scaffold ensured optimum accessibility.

Contractor Mitrajaya Bhd., Puchong Field Service PERI Malaysia

It would appear that the new administration building of the Malaysian Anti-Corruption Commission (Suruhanjaya Pencegahan Rasuah Malaysia, in short: SPRM) in the government district of Putrajaya stands on very shaky foundations, because the first 30 floors of the three building complexes are elevated on delicate inclined supports. A massive intermediate level seems to hover 40 m above the ground.

Leslie Lim Project Manager “The know-how of the PERI engineers proved to be invaluable for our project. Their individual, innovative planning services resulted in safe, productive and timesaving execution solutions. A large proportion of the overall concept was the use of PERI UP which meant we could easily master the challenging shoring issues.”

With the help of RCS Climbing Formwork units, CB Working Platforms and BR Shaft Platforms, the vertical reinforced concrete components and circular inclined supports were constructed. As formwork, the VARIO GT 24 Girder Wall Formwork was mainly used. Following the fast working speed, PERI UP was assembled as birdcage scaffold in a 1.50 m x 1.50 m basic grid. As a result, safe working and access levels as well as corresponding intermediate supports could be realized in order to install ST 100 Stacking Towers as horizontal bracing for temporary stabilization of the inclined reinforced concrete columns.

For a comprehensive service from a single source, PERI engineers planned and delivered the wall, slab and climbing formwork through to the most appropriate type of formlining. In particular, the spatial working and shoring solution on the basis of the PERI UP Modular Scaffolding system ensured the fast construction of a stable structure base from the beginning onwards.

On the basis of the RCS Rail Climbing System, the inclined circular columns could be efficiently constructed.

Working scaffold, bracing and shoring rolled into one: PERI UP subsequently followed as birdcage scaffolding within the cycle of the RCS Climbing Formwork.

The 220 m high, waist-like office tower with an elliptical ground plan is flanked by a 55 m high building on each side. The core elements of the comprehensive formwork and scaffolding solution were the self-climbing formwork for the core of the Warsaw Spire as well as the full-perimeter climbing protection panel. Efficient and safe technology along with a number of additional services ensured that the tight construction schedule was successfully maintained. The PERI formwork solution took into account both the challenges of the complex building form as well as making it possible to comply with the strictly defined construction phase. The key element was the use of hydraulic climbing systems because the climbing formwork and climbing protection panel could move from floor to floor without the need of a crane: the ACS used a climbing device with 100 kN lifting power while the RCS P Climbing

Protection Panel was lifted upwards by means of mobile climbing devices. One of the key challenges was adapting the RCS Climbing Protection Panel to match the variable elliptically-shaped storey slabs of the office tower. In addition, a weekly cycle per floor was necessary to maintain the planned short construction period. To ensure that the protection panel was always securely connected to the building, different cantilevered slab shoes were used for horizontally anchoring the climbing rails to the floor slabs thus compensating for the projections and recesses in place between the floor slabs. Three platforms provided access on all sides for pre-tensioning the reinforced concrete slabs. For forming the core walls, two ACS self-climbing versions were used: the ACS P Platform system provided generously-sized storage and working areas for the core walls formed in

project participants resulted in a remarkably short implementation period: planning start was mid-2012, the first excavators arrived in April 2014 and, after only 10 months of construction, the entire building shell was completed with a total floor area of 19,000 m². Together with PERI specialists, the site management team developed a formwork concept that ideally matched the ambitious construction schedule and project requirements. The two topmost floors under construction were completely enclosed with the help of the RCS Climbing Protection Panel. This enclosure served as protection against falling and reliably shielded the working area from the effects of the wind and weather. Thanks to the mobile RCS climbing hydraulics, no crane was required for the rail-guided moving procedure. An integral part of the PERI climbing concept was the RCS MP

Landing Platform which was used for moving and intermediate storage of formwork materials. The storey slabs were also formed crane-independently. Lightweight aluminium SKYDECK components, systematic assembly sequence and the low number of props required accelerated the shuttering procedure; in addition, the SKYDECK Drophead System facilitated early striking. Also the fact that the total number of infill areas was below 5% ensured rapid moving procedures. During construction of the base level slabs, SKYDECK Platforms also guaranteed a high level of safety at the slab edges.

The PERI complete solution consisting of formwork, scaffolding and related services guaranteed safety at all heights and rapid construction progress. The Climbing Protection Panel RCS P served as a gap-free enclosure for the top 3 storeys under construction in the building shell. As a result, the construction team could also work at great heights with more productivity. Mobile self-climbing devices reduced crane requirements on the jobsite. Integrated into the climbing system was an RCS Landing Platform which served as a temporary storage area and for moving the loads into the other storeys with the crane. For constructing the core walls, VARIO GT 24 Girder Wall Formwork was connected with CB 240 Climbing Brackets to form large-sized units. The allowed

safe working conditions at all heights combined with easy handling with trouble-free adaptation to suit the different building geometries. PERI UP flights of stairs for safe access of the higher-positioned working areas supplemented the comprehensive PERI solution as much as the formwork and scaffolding solutions for constructing the massive floor slabs with thicknesses of up to 1.00 m as well as the simultaneous concreting of the large-sized beams. An extensive range of planning services, along with a competent PERI supervisor on site, made a further valuable contribution for maintaining the tight schedule and budget requirements.

Construction of the elevator and stairwell shafts took place in advance with the help of a CB/VARIO Climbing Formwork solution.

The 52 floors of the high-rise building provide space for 250 private apartments and are characterized by the circular floor plan. The core of the building was also designed as a central circular structure.

cooperation with the site management – with the focus placed firmly on site-compliant execution. In the lower storeys, there are six centrally-arranged elevator shafts with internal dimensions of only 2.30 m x 3.00 m. For this, the construction crew used the self-climbing ACS S Shaft Formwork whereby the climbing device was positioned in the centre of the shaft. The TRIO Panel Formwork and the trailing working platform were suspended on the climbing device. From floor 28 onwards, the geometries change in the core of the building: six smaller elevator shafts merge into four larger ones. At this point, the shaft formwork was coupled together and an ACS Multi-Unit Aggregate then simultaneously lifted the complete sets of formwork from floor to floor.

PERI engineers in Germany developed the range of assembly plans whilst the required cutto-size timber formers were realized at the PERI facility in Moscow. After the individual components had been delivered, site personnel assembled the formwork units on the jobsite – an efficient and cost-effective execution solution. The RCS Climbing Protection Panel completely enclosed the building edges of the uppermost floors still under construction. This protected site personnel against falling and facilitated safe, continuous working operations also at great heights – sheltered against the wind and regardless of the weather. This meant up to three standard floors per month could be realized.

For the different areas of the building, the PERI concept provided four different climbing versions on the basis of the RCS Rail Climbing System which fully complied with the requirements of safe and rapid construction progress through specially adapted platforms. One particular challenge was the design of the forward and reverse- angled protection panels for the archshaped facade. PERI provided an allround enclosure adapted to suit the

ground plan which resembled a ship's bow; in addition, it facilitated the fast assembly of precast parapets. As a rear protective wall on the RCS Climbing Formwork, the construction team used floor-to-ceiling side mesh barriers from the PROKIT Safety System. The PROKIT was additionally covered with tarpaulin so that pedestrians could safely walk past. In addition to the climbing solution, PERI also supported the rapid construction progress with the planning and delivery of PERI UP Shoring and GRIDFLEX Girder Grid Slab Formwork.

viding complete protection at all times. Foldable covers at the base of the climbing protection panel guaranteed safe working operations in the areas below. In particular, the comprehensive PERI solution took into consideration the varying floor heights of between 3.80 m and 5.50 m while working platforms on the slab edges provided up to 75 cm working spaces for pre-stressing the reinforced concrete slabs. Integrated into the PERI climbing solution were two RCS landing platforms which served as temporary storage and moving of materials.

The housing with the lightweight LPS climbing protection panel units reliably protected site personnel working in the upper floors under construction against falling. Very light grid elements ensured a high level of safety and wind-protected working areas due to the close-mesh design while the permeable structure allowed light into the building and simultaneously reduced the load on the anchoring in the building. Then, the protection panel units were an impressive 18.50 m high and provided extremely safe working conditions for up to 5 floors at the same time.

A high level of safety along with optimised construction processes was guaranteed through the mobile hydraulic climbing devices. As a result, no crane was required for moving the LPS protection panel units. This speeded up construction progress significantly as forming and concreting as well as climbing could take place at the same time early in the morning.

The diverse features of each floor required detailed formwork planning as well as static calculations for each stage during the construction. Safety for all site personnel and passers-by was given absolute top priority throughout. In addition, the PERI solution took into consideration the extremely cramped conditions due to the central inner-city location along with maintaining the tight construction schedule.

56 Leonard Street is both the name and address of an extraordinary skyscraper in Manhattan. The slender tower rises to a height of 250 m and features 145 luxury apartments and 10 penthouses on close to 60 floors.

For the realization of the floor slabs, including the countless recesses and cantilevers, PERI engineers developed a project solution on the basis of rentable modular construction systems. RCS Climbing Protection Panel units, in combination with wide cantilevered slab tables, guaranteed safe working conditions on all sides. In particular, transferring the loads to the external corners was a big challenge for all project participants. Here, aluminium MULTIPROP Post Shores together with core components from the VARIOKIT Engineering Construction Kit formed geometrically and statically adapted supporting systems which reliably carried the high loads into the lower-positioned floors of the building.

RCS rail-climbed the 45 floors of the Providence Towers and, as climbing formwork together with protection panel, facilitated efficient and safe working procedures without any interruptions.

Contractor John Reddington Ltd., Borehamwood Field Service PERI Ltd. UK, Rugby

Circular forms and cascaded building structures characterize the “New Providence Wharf” residential project on the much sought-after Thames Embankment location in London. In recent years on a 3.3 hectare, former derelict industrialsite in the Docklands areain the eastern part of the capital, exclusive apartments as well as offices, retailstores, restaurants and various culturaland recreational facilities have been realized in several phases. With its 45 storeys, the 136 m high Providence Tower dominates the surrounding buildings. The interaction of the apartment and high-rise hotel with the oval ground plan and balconies arranged in a wind vane fashion with the likewise circular-shaped ground floors features a characteristic architecture.

The RCS Rail Climbing System formed a cost-effective basis for efficient and safe construction of the high-rise core and floors. As formwork scaffolding for the in part narrow and angular shaft 204

geometry, RCS was combined with TRIO Panel Formwork. The variable core ground plan was likewise taken fully into consideration as well as the upwardly tapering wall thicknesses. In addition, the RCS System served as a climbing protection panel for complete enclosure of the building shell floors. This meant that site personnel were protected against falling and the effects of the weather at all times. This facilitated safe and very productive working conditions also at great heights.

The formwork concept for the high-rise complex was based on the broad PERI product range. As a result, the most appropriate system was used each time to suit the different requirements. In particular, the strict schedule, stringent safety requirements and compact construction site with very limited storage and crane capacities required well thought-out and coordinated PERI implementation planning. For forming the reinforced concrete slabs, SKYDECK was used with MULTIFLEX supported through aluminium MULTIPROP Slab Props. With the help of RUNDFLEX and TRIO, the walls could also be concreted in fast cycle sequences and, if required, combined with SB Brace Frames and CB Climbing Platforms.

Michael Riordan Project Manager “We used a complete range of PERI equipment, which have all been engineered towards our construction specifications. We saved time, ensured safety and the climbing systems enabled us stick to the project time scale without having to stop and start.”

Slab tables with the integrated Table Swivel Head and PEP Ergo Slab Props are an integral part of the comprehensive PERI complete solution.

The PERI Climbing Formwork solution is based on different ACS variants individually adapted to suit the project requirements. Centerpiece is the climbing hydraulics with the ACS Climbing Device.

The Al Habtoor City Towers are 3 high-rise buildings in Dubai which are simultaneously being realized, eventually reaching heights of around up to 300 m. The decisive factor for ensuring compliance with the short construction period is the formwork concept for the reinforced concrete cores. Here, the modular ACS Self-Climbing Technology facilitates high productivity and short cycle times.

two 307 m high skyscrapers and one with a height of 213 m are steadily reaching higher and higher into the sky. At the beginning of 2017, close to 1,500 new exclusive apartments will be available in the desirable and highly sought-after residential area on Sheikh Zayed Road. Massive reinforced concrete cores with very impressive dimensions form the respective centres of the three high-rise buildings, including the wing walls which feature outer dimensions of 40 m x 32 m. The focus of the PERI complete solution therefore is very much on the climbing formwork concept for the high-rise building cores. With the help

The Al Habtoor City Towers skyscraper complex is currently one of the largest high-rise building projects in Dubai. Within the space of only 32 months,

of the ACS Self-Climbing Technology and VARIO GT 24 Girder Wall Formwork, a systematic, continuous workflow has been achieved. Climbing, shuttering,concreting and striking can take place in regular 5-day cycles without requiring any crane support. In addition, the different ACS versions have been perfectly matched to each other so that two placing booms for every core respectively can be climbed at the same time. Due to the non-dependence on crane capacity as well as not being affected by the weather, there are no work stoppages.

The two 307 m high-rise structures each have 75 floors while the third building reaches a height of 213 m and has 52 floors. The core and supporting walls are climbed in advance and crane-independently with ACS and VARIO. For each high-rise core, two placing booms are carried with the help of the ACS Self-Climbing System.

Hayder Awni Project Manager “PERI´s ACS system has once again proved its uniqueness. We can safely and quickly realize our very complicated core wall as well as in a very high quality with the ACS without having to utilize the crane. This is a big advantage on our construction site.”

Torre Banco Macro, Buenos Aires, Argentina Bank high-rise building with elegant tower finish

The modern architecture with its stylistic features placed high demands on the execution of the building work. For the construction of the bank high-rise structure, which was designed by César Pelli, the requirements could be met with the help of a customized formwork and shoring solution while simultaneously optimizing the work performance. The Torre Banco Macro is the new headquarter of the Argentinian bank of the same name. Star architect, César Pelli, provided the 135 m high office tower in the centre of Buenos Aires with a very distinctive top section which features an elegantly curved rooftop landscape. At the same time, the otherwise oval almost egg-shaped ground plan tapers upwards with the outer edges of the longitudinal sides transforming from a convex to a concave shape in the upper quarter. For construction of the 1.300 m² standard floors, PERI´s Argentinian engineers designed a project-specific slab table solution. A total of 42 rectangular and trapezoidal slab and edge tables were individually assembled based on 4 different radii and subsequently adjusted to suit the oval ground plan 208

which then ensured fast cycle sequences. When forming the core walls, the PERI solution – on the basis of the VARIO GT 24 Girder Wall Formwork system – likewise fulfilled the high requirements. The core geometry was extremely complex but, in spite of this, the 3.90 m high core walls could be realized in architectural concrete quality. For the slabs and walls, the quantities of equipment required on site were determined so that efficient working operations were realized with cost-effective material usage.

In order to form the three-dimensional spiral reinforced concrete edge beams of the upper floors at a height of 135 m, lightweight MULTIPROP Alu Props with MRK Frames were connected to create load-bearing shoring towers. Here, the modular system allowed flexible adjustment and extension possibilities. The 4-legged and multi-legged MULTIPROP towers were realized with variable heights ranging from 5 m to 16 m – while taking into consideration different assembly areas and intermediate levels.

Martín Bredda Site Manager ”In particular, the upper part of the tower with its distinctive geometry and the varying inclinations as well as the load transfer to different assembly levels presented substantial challenges. The PERI solution adapted itself perfectly to suit the given requirements and allowed us to optimize the work performance. I would like to especially highlight the engineering performance of PERI – through their support and the constant exchange of ideas with our site management, we could work out the best solution.”

Cultural buildings are mainly used as public meeting places. In the form of theatres, museums or sports facilities, they are very often characterized by extraordinarily high architectural standards. The complex geometries and frequently high architectural concrete requirements of these structures have an impact on the planning and realization. Due to the fact that these places are used by the general public, e.g. for concerts and other public gatherings, this often results in higher load assumptions, load concentrations and spacious access points and emergency escape routes which must be kept free – a challenging task for all project participants.

“I rate the PERI contribution very highly. All requirements were completely fulfilled and the tight construction schedule was also maintained. In addition to the fast shuttering and moving times with MAXIMO and SKYDECK, I would like to especially praise the on-site project support along with the flexible, operative and process-oriented cooperation with the PERI engineers.”

Contractor Hochtief Building GmbH, Rohbau/Industriebau Berlin Field Service PERI GmbH Germany, Berlin

For the reconstruction of Berlin´s City Palace, PERI supplied cost-effective formwork and scaffolding solutions from one source. In addition to fast shuttering and moving times, the on-site support provided by the PERI engineers in particular ensured that the very tight construction schedule could be maintained. In order to ensure that rapid construction progress could be realized, large quantities of formwork and scaffolding materials were in everyday use. In addition to the provision of modern and time-saving systems, full consideration of all construction tasks in particular was an important element of the PERI overall solution. The well thought-out safety technology, provision of project-specific special formwork assemblies, project management by the PERI project leader as well as the planning and supply of formwork and scaffolding from one source had an extremely positive effect along with accelerating the work processes. Over 6,000 m² of MAXIMO Panel Formwork with the one-sided MX tie technology guaranteed significant time 212

savings during all shuttering and striking operations. For forming the reinforced concrete slabs, systematic shuttering operations could be carried out with a total of 10,000 m² SKYDECK materials and – due to the low individual weights – easily stripped again. The Drophead System also ensured fast cycle sequences with a simultaneous reduction in material usage. Support for the large slab heights was provided by the lightweight MULTIPROP Aluminum Props which, in turn, could be supplemented by shoring towers created using MRK Frames. Due to the PERI solution with external CB Climbing Platforms, no facade scaffolding for the shell construction was required. In the area of the main entrance on the west side, PERI Berlin also provided ready-to-use customized special formwork to the construction site. For the circular reinforced concrete walls of the cupola, RUNDFLEX Circular Formwork was used together with FB 180 Folding Platforms. The final stage of the cupola construction took place using PERI UP Shoring and Working Scaffold.

The new cultural centre in the south of Athens is based on the innovative design by the Italian star architect Renzo Piano. PERI supported the construction of this extraordinary project with a comprehensive formwork and scaffolding solution, continuous on-site supervision along with a well thought-out logistics concept. The two distinctive main buildings – the National Library and Greek National Opera – are located at the rear of a man-made hill which is the side closest to the sea. The sloped roofs of the buildings form, as it were, an extension of the incline. Similar to a flying carpet, the roof construction of the National Opera is suspended at a height of 40 m above the actual building roof, supported by 30 filigree steel columns. For constructing the 10,000 m² canopy, the PERI UP shoring solution fulfilled a wide range of functions.

In addition, full-surfaceworking levels adapted to match the inclined course of the roof accelerated connecting and supplementary operations with in-situ concrete and provided maximum safety. Specially designed, floating supports minimized the movements of the scaffold construction and reliably provided the required earthquake protection also during the execution phase. Load distribution took place with the help of VARIOKIT system components taken from the PERI rental park. The VARIO Girder Wall Formwork and the SRS Column Formwork fulfilled the high architectural concrete requirements for the walls and columns. The up to 32 m high reinforced concrete retaining walls which separate the artificial hill from the rest of the park were also realized in an architectural concrete finish. PERI engineers took into account the defined arrangement of the panel joints and anchor points in accordance with the design specifications whilst FinPly formlining screwed on at the rear also ensured immaculate concrete surfaces.

A customized PERI formwork and scaffolding solution with 3,500 project-specific special formwork elements ensured that the realization of this extraordinary museum was carried out within the specified time-frame and budget. Located on the highly prominent Pier Maua, this futuristically designed building was designed by the Spanish architect and engineer, Santiago Calatrava, and extends 300 m into the sea. The cantilevered roof and facade with moving elements ensure optimum air conditioning. Two storeys are connected by means of inclined ramps and have a total area of 5,000 m² which will showcase trend-setting exhibitions and technologies.

For the 3D planning, the Weissenhorn engineers were supported by experienced specialists from the PERI subsidiaries in Spain and Poland. The respective assembly plans and data provided the basis for the dimensionally accurate CNC-controlled cutting of the formwork units and final assembly at PERI´s facility in Sao Paulo. Here, CNC wood working equipment was used to process around 60,000 m² chipboard to create the formwork units in two-shift operations for the single and double-curved formwork elements. 25 formwork erectors ensured that between 10-20 ready-to-use customised elements were delivered to the site every day – just-in-time according to the construction schedule – over a period of 13 months.

In order to allow the complex concrete design of the museum to become reality, PERI planned, produced and delivered more than 3,500 project formwork elements, mostly double-curved 3D formwork units. For the comprehensive formwork and scaffolding planning together with the assembly of the formwork elements, international PERI teamwork was responsible throughout.

In order to be able to cost-effectively realize such exceptional formworking tasks, a high proportion of system components were used. In addition, VARIO basic elements were selected which allowed efficient handling on the jobsite – similar to system formwork. Furthermore, three supervisors provided support for the extensive on-site formwork operations.

MULTIPROP shoring towers and VARIOKIT system components formed the up to 14.75 m high supporting structure – together with the TRIO panel formwork, the partly inclined, up to 1.50 m thick sandwich-type reinforced concrete walls could be cost-effectively realized.

For the characteristic, wood-like surface structure, a special plaster was applied by means of a roller template. This required a consistently high quality of the concrete surface finish which was achieved through the use of the TRIO panel formwork.

The PERI formwork concept minimized the use of special formwork – as a result, the wide range of reinforced concrete components with numerous offsets and inclined surfaces could be economically constructed.

The museum features a traditional village hut which gradually falls apart. Numerous offsets and inclined surfaces characterize the structure as well as the distinctive timber-like structure of the finished architectural concrete surfaces. A customized system combination of formwork and shoring was developed to match the complex architectural requirements which, in turn, minimized the use of special formwork.

For the erection of the extraordinary Pegasus bronze sculpture near Miami/Florida, PERI UP Rosett provided optimal working conditions. The Modulars Scaffold System proved once again just how flexible and versatile it is, adapting to the complex geometry in 25 cm increments. Since the end of 2014, a spectacular piece of bronze artwork has formed the centre of the new theme park at Gulfstream Park near Hallandale Beach in Florida, one of the most famous racetracks in the world: Pegasus, the fabled winged horse from Greek mythology. The oversized sculpture is an impressive 33 m high and – Pegasus together with the dragon – over 60 m long. In order to realize such magnitude, in connection with the organic shape in bronze, seemed a virtually impossible challenge at the beginning for all members of the project management team. Within a period of 2 years, 250 t and 400 t of bronze and steel respectively were formed thus realising the cus220

tomer´s conceptual presentation in a larger-than-life format. A total of 1,250 bronze parts were ultimately needed in order to assemble the sculpture as a 3D puzzle around the supporting steel structure. The dimensions were truly enormous as each of the castings was approx. 3 m² large and weighed 200 kg. In order to be able to safely realise the bronze sculpture on site as well as within the planned time frame, the metric 25-cm scaffold grid provided the required maximum level of flexibility in all directions. As a result, suitable working and access levels for the craftsmen and metal designers were created – adapted on the outside and inside to match the complex, organic form as well as continuously following the erection progress. In addition, auxiliary building sections simultaneously under construction which were to be joined to the sculpture also had to be taken into account during the scaffold planning and assembly. For this, PERI UP could be ideally combined with system components taken from the VARIOKIT Engineering Construction Kit – a big advantage, especially for large-span bridging.

VARIOKIT System Components supplemented the PERI UP Scaffold Solution in particular for the large-span bridging.

PERI UP provided very safe working conditions for the craftsmen and metal designers during the realisation of the 33 m high bronze work of art.

The Modular Scaffolding could be flexibly adapted to suit the organic form in 25 cm increments.

With the help of the PERI UP Scaffold Solution, more than 1,000 bronze castings for the Pegasus sculpture were joined together and welded on site.

PERI UP shoring towers support the MULTIFLEX Girder Slab Formwork in order to efficiently construct the cast in-situ slab at a height of almost 8 m.

The two modular construction systems, VARIOKIT and PERI UP, formed shape-generating shoring for realizing the inclined grandstand stringers.

The new construction of the multifunctional sports and event arena in Moscow required very detailed formwork planning as well as the combined use of versatile system equipment.

The reinforced concrete walls were formed with help of VARIO GT 24 Girder Wall Formwork and TRIO Panel Formwork. For the construction of the columns which featured a wide range of dimensions and ground plans, use of the VARIO and SRS Column Formwork Systems resulted in excellent concreting results. For forming the circular walls, the continuously adjustable RUNDFLEX Circular Formwork system was used. This was – as part of the reinforcement measures along the historic stadium facade – assembled together with SB Brace Frames for carrying out single-sided formwork operations.

The VTB Arena is the new home ground for the Russian football club FC Dynamo Moscow. The 26,000 capacity stadium is an extraordinary multifunctional arena equipped with the very latest technology, and has been designed to host a wide range of events and thus ensure a high degree of utilization. The football pitch and ice hockey arena are accommodated under one roof and, within only a few hours, the facility can be converted into a basketball hall or concert venue. The new football pitch is positioned 8 m above the old playing surface; this means an extensive underground area is available for parking and retail businesses. Only the listed west facade testifies to the existence of the otherwise completely demolished old Dynamo Stadium. For ensuring on-time completion of all in-situ concreting operations, PERI engineers developed a formwork and shoring solution based on multifunctional system equipment.

Lascaux IV Visitors Centre, Montignac, France Museum and cave replica with complex shapes

“The Centre International d’Art Pariétal (CIAP)“ museum complex in south-western France is the impressive result of a formwork concept designed in great detail. The rather complex shapes along with the highest surface quality requirements demanded an extensive range of planning services and continuous on-site supervision. In addition, the full range of safety equipment featured in the formwork solution met the very stringent requirements. The world famous Lascaux caves has been a UNESCO World Heritage Site since 1979 and the around 17,000 yearold cave paintings found inside are among the oldest known artwork in the history of mankind. With a new, unique visitor´s centre, the exceptional historical heritage is presented as authentically as possible. The exact replica of the cave has been realised on a scale of 1:1 and allows visitors to move through the historic cave virtually by means of augmented reality; the valuable cave paintings are presented using a range of modern visual effects.

The wall formwork combination using TRIO and VARIO allowed the construction of the 13.50 m high walls with variable inclinations.

Cultural Buildings

The complex is perfectly integrated into the hilly landscape as the building follows the contours and is pushed, as it were, under its surface. The very impressive design has been realized through a range of inclined walls up to 13.50 m high. The construction of the approx. 2,500 m² wall surface complete with varying inclinations was carried out using PERI standard systems and supplemented by safety equipment of the highest standard. FinPly formlining was used to cover the entire wall formwork which meant concrete surfaces could be realized in a high quality execution. The numerous inclined walls were constructed with TRIO panel formwork. For concreting as well as anchoring and connecting the elements, the modular MXP Platform System provided safe access from all sides. With corresponding end platforms and guardrails, PERI´s French engineers provided safe and reliable end-to-end anti-fall protection. Customized elements on the basis of the VARIO GT 24 Wall Formwork System were used in particular in the corner areas which featured two wall surfaces with inclinations in opposite directions thus resulting in complex intersections.

Modular safety: the MXP Platform System exactly matches the element widths of the MAXIMO and TRIO Panel Formwork Systems.

The MXP Platforms are securely connected with the TRIO components. With only a single crane lift, complete large-area units could be moved.

For this, special customized formwork elements were combined with TRIO Standard Panels which ensured simple and fast working operations. For the World Expo in Milan, the host country presented an architectural highlight: the 35 m high “Palazzo Itali”, a complex shaped reinforced concrete building featuring 6 floors and a photo226

voltaic glass roof, embraced by a delicate outer envelope (“skin”). Compared to the other pavilions, the structure was the only permanently piece of architecture at Expo 2015. In order to meet the scheduled completion date, construction crews worked around the clock in 3-shift operations. In addition, the PERI project management team organized material logistics and technical support through its efficient on-site support activities with corresponding availability at short notice. In particular, however,

of aluminium MULTIPROP Props – also across the height of several floors – until the inherent load-bearing capacity of the structure had been reached. PERI UP Flex served as a modular load-bearing system for formwork support as well as the structural steel assembly, and optimally adjusted in 25 cm increments to match the com-

plex geometry and corresponding load concentrations.

Lightweight aluminium MULTIPROP Slab Props were used to provide support over the height of several floors.

PERI Italy planned and delivered almost 800 m² of special steel formwork as well as 2,000 m² TRIO and 2,500 m² SKYDECK in a very short time.

For the quiver-shaped reinforced concrete components, precisely manufactured special steel formwork elements were connected with standard TRIO Elements. The modular formwork solution could therefore be used for the

range of heights, and ensured simple and fast work operations also for such complex building structures. For forming the walls, a total of 2,000 m² of TRIO Panel Formwork was used; in addition, the elements were also compatible for use with RUNDFLEX Circular Formwork and TRIO Column Elements.

PERI Italy planned and produced in a TRIO-compatible special formwork within a very short space of time which, in connection with formwork and scaffolding systems taken from the PERI rental park, considerably accelerated the construction progress. On site, a PERI supervisor ensured efficient working operations right from the start. Slabs were formed with SKYDECK and MULTIFLEX with support using PEP and MULTIPROP Slab Props. The high loads were safely transferred by means

The Dubai Frame is a huge frame located in the middle of the green Zabeel Parks: 155 m high and 93 m wide – without doubt the largest picture frame in the world. The real backdrop of Dubai serves as the work of art. Glass elevators take visitors to the top where they can enjoy breathtaking panoramic views from the 75 m bridge structure which is fixed between the two towers – visitors see old Dubai on one side and to the other side new Dubai with its skyscraper architecture. In the centre of the bridge, a 120 m² glass floor provides an additional perspective of a direct view to the ground far below. Also at the base, both towers are connected by an accessible podium which optically closes the picture frame and creates additional space for exhibitions. 228

The frame profile itself has a very special shape. Both towers were built as reinforced concrete structure with a trapezoidal-shaped, extremely slender ground plan. Within the angular core geometry, the partly only 30 cm thick walls had to be concreted and climbed. For this, the PERI engineering team from Dubai designed a bespoke formwork solution in collaboration with ARP to suit the specific project conditions. They combined three different ACS Self-Climbing versions with VARIO Girder Wall Formwork and TRIO Panel Formwork. Within the narrow shaft dimensions, the elevated and suspended platforms along with the integrated access technology provided valuable working space and a maximum level of safety. Thus, work could be carried out crane-free achieving a 3 ½ days climbing cycle time which saved valuable construction time.

Similarly, the inclined reinforced concrete columns could also be realized on the ground with the help of system components – by means of a load-bearing system based on the VARIOKIT Engineering Construction Kit and PERI UP Modular Scaffold System.

Numerous other execution solutions rounded off the PERI complete package – for example, for the tops of the two towers. In the transition area to the 2.100 t bridge steel construction, the cores had to be reinforced with the formwork solution being adapted accordingly. For transferring the loads of the up to 3.50 m cantilevered and 1.40 m thick intermediate slabs, SB Brace Frames were used horizontally.

For realizing this iconic walk-in work-of-art structure, PERI formed a project team comprised of climbing and formwork specialists. From the very beginning right through to the end, they supported the complex shell construction with precisely matched execution solutions on a system equipment basis. As a result, the angular core geometry could be realized within the very tight dimensional tolerances; in addition, 30 days construction time was saved.

Contractor Graña y Montero S.A., Lima Field Service PERI Peruana SAC, Lima

Humberto Cueva Carrascal Site Manager “With the selected PERI systems, we have achieved an enormous work performance as well as the high level of execution demanded by the client.”

The provision of correspondingly large quantities of materials as well as the selection of the correct system in each case to meet the different requirements were decisive factors in order to complete the architecturally-demanding university campus structure within the given tight construction schedule.

230

The new campus building of the UTEC University (Universidad de Ingeniería y Tecnología) is in the shape of a huge arena: to the north in the direction of the motorway, the reverse-inclined outer facade has the effect of a steep, artificial cliff. To the south, the 10-storey, almost 50 m high structure cascades downwards in a series of steps – similar to that of a grandstand in a sports stadium.

In the space of only 15 months, 40,000 m³ of concrete and 4,500 t of steel were brought into the required shape. For this, PERI´s Peruvian engineers developed a comprehensive, project-specific formwork and scaffolding solution. Thus, it was possible through economical means to realize the shell construction within the very tight construction schedule in spite of having only three cranes available.

The lightweight – and mostly moved by hand – LIWA and DOMINO Panel Formwork Systems reduced crane utilization for shuttering the walls – whilst simultaneously guaranteeing fast forming times. For the construction of the numerous architectural concrete walls, VARIO GT 24 Girder Wall Formwork achieved optimal results. In combination with the CB Climbing System, the platforms and formwork were moved

as single climbing units in one crane pick – this shortened the crane and construction time respectively. The MULTIFLEX Girder Slab Formwork was supported by aluminium MULTIPROP Slab Props as well as PERI UP Shoring Towers. As a result, the grandstand-style, staggered floor slabs with varying floor plans, slab thicknesses and floor heights could be optimally

constructed. Especially in the area of the reverse-inclined north facade, the high loads were safely transferred over several storeys by means of PERI UP. Here, cantilever-mounted VARIOKIT Bracket Units also served as erection areas for the shoring required for subsequent floors.

Singapore Sports Hub, Singapore Suspended working platforms for safe roof assembly

Cultural Buildings

Suspended PERI UP Working Platforms ensured the safe installation of a spectacular stadium roof in Singapore. Singapore's new national stadium accommodates 55,000 spectators and is designed to cater for more than 150 different sports as well as hosting concerts and holding parades. As one of the most modern sports venues worldwide, the sports complex also features a movable roof construction. In spite of the enormous dimensions, with a 312 m span and a height of 80 m, the roof can be completely closed in only 20 minutes and provides protection against the sun and rain in a very short time. The vaulted roof architecture prevents any heat accumulation inside the stadium itself and can be opened in a south-west direction which ensures optimum air circulation. In addition, this provides spectators with an impressive unobstructed panoramic view of Singapore's skyline.

For the assembly of the steel roof construction, PERI UP Flex Modular Scaffolding could be flexibly adapted to suit the spatially complex geometry of the steel framework and thus ensured safe working conditions. PERI UP had already been fixed to the roof trusses on the ground and subsequently lifted as a complete unit with the crane into position. SRU Steel Walers from the PERI rental pool served as the basis for the realization of the suspended scaffolds. All required working levels were therefore available from the beginning onwards – without any time-consuming assembly operations at great heights. The basis for the exact arrangement and alignment of the suspended scaffolds was the detailed 3D planning by PERI scaffolding specialists with the help of PERI CAD. On site, the lightweight components along with the largely tool-free assembly operations accelerated the scaffolding work while the high node rigidity and the system-integrated protection against lifting of the PERI UP system decks guaranteed stability and a high level of working safety.

Third Bosphorus Bridge, Istanbul, Turkey Highest bridge pier in the world formed with ACS

The 59 m wide Yavuz-Sultan-Selim-Bridge carries 8 lanes and two railway tracks with a span of 1,408 m across the Bosphorus, and connects – as part of the new North Marmara Motorway – the European and Asian continents. For the construction of the two pylons, efficient workflow processes as well as very high productivity and extremely short cycle times could be achieved with the ACS self-climbing system and VARIO GT 24 girder wall formwork. In addition, the high requirements in terms of flexibility, surface quality and dimensional accuracy were maintained throughout. Construction of the upper area of the pylons was carried out in a total of 21 sections each with a 4.60 m concreting height. ACS V, the continuously adjustable version for all inclinations, could be optimally adapted to match the forward and reverse slopes of the side surfaces. For the almost vertically-positioned surfaces, forming was carried out using the standard ACS R version. The internal formwork was climbed with the help of the ACS V and ACS P 236

platform variant. All ACS climbing units were provided with completely closed trapezoidal sheet cladding which provided anti-fall protection as well as additional wind and weather protection for site personnel in the lower levels. For the reinforcement work carried out in advance in the upper platforms, the perforated sheeting offered a high level of safety and let in daylight.

The triangular-shaped base structure with broken corners tapered constantly upwards. Over the height of the pylon, the 3 long polygon sides are reduced by 1.40 m respectively. Formwork adjustment took place using compensation plates and bolted filler elements which were gradually dismantled as required, while working platforms were adapted by means of centrally positioned filler platforms. On the forward-inclined ACS platforms, a rotary distributor for concreting was climbed at the same time while access to the elevator was also integrated in the self-climbing system during the planning phase. In particular, for the assembly of the large-sized steel mounting components for the stay cable holding devices, the PERI solution offered the required flexibility. Any collisions with the stay cable boxes could be avoided whereby their dimensions and positions had already been taken into consideration when determining the climbing axes.

The 1,408 m long suspension bridge across the Bosphorus is supported by two A-shaped reinforced concrete pylons – the highest in the world with a height of 326 m. The demanding geometries and complexity of the mounted parts required a very flexible planning process in the form of a complete solution.

Samet Seyhan, Project Manager (ICA) Evans Baek, Deputy Project Manager (Hyundai/SK) “The pylons are unique and extremely complicated due to the inclined conical shape and the numerous embedded items. The ACS system was the right decision for this type of bridge project because of the huge experience of PERI. Getting competent and comprehensive support to suit our tight schedule and providing completely safe working platforms at all levels and at any height were other positive aspects of PERI ACS system.”

Rem Nahshon Project Manager “Building a bridge reveals many challenges along the way. PERI was the best partner for that matter, being focused on our requirements with innovative design and ideas, on-site support and excellent equipment: PERI UP as ‘stand-alone’ shoring and VARIO KIT as stiff formwork units.”

For routing the highway over a railway line, PERI´s Israeli engineers ideally matched the superstructure formwork with the shoring. The fast assembly and fast cycle sequences saved working time and accelerated the construction progress. The Ayalon Highway (20) is the main traffic artery of the region in and around Tel Aviv. It is being extended to the north and, at Shefayim, it joins Highway No. 2 which heads in the direction of Haifa running parallel to the Mediterranean coast. For crossing a railway line, the construction of a 450 m long bridge was required.

238

The 15.60 m wide superstructure of the 12-section bridge was constructed with T-beam cross-sections using in- situ concreting operations. Webs and plates could be concreted in one pour with the help of PERI bridge formwork – without requiring any additional horizontal anchoring through the webs. VARIOKIT raised formwork units units were positioned on supporting scaffold based on the PERI UP Modular Scaffold system. For this, 1.50 m wide and 15.75 m long framework units were formed while load-optimized adjustments were carried out by integrating 150 cm and 75 cm field widths. For realizing the construction in only

4cycles, the concreting cycle lengths were each 115 m. The special feature of the PERI solution was that the generously-dimensioned formwork units could be fixed to the bridge superstructure by means of DW 15 tie rods after concreting and curing had taken place. As a result, the relieved PERI UP supporting structure could be quickly moved to the next cycle each time. The formwork units were subsequently lowered using winches and could likewise be transported to the next phase of construction without requiring any time-consuming dismantling work.

The two modular construction systems, PERI UP and VARIOKIT, could be flexibly adapted to suit the bridge geometry and loads.

The approx. 8m x 3m generously-dimensioned formwork units on the basis of the VARIOKIT Engineering Construction Kit could be moved using only one crane lift thus saving time.

The PERI formwork and shoring solution as well as the continuous on-site support accelerated the construction work on the 450 m long motorway bridge (Building Structure 301).

The VARIOKIT balanced cantilever solution resulted in dimensional stability while the formwork facing with its board structure provided excellent concrete surfaces.

The combinability with PERI UP facilitated the realization of safe working areas along with access to all areas of operations.

For the bridge superstructure, PERI civil engineering technology experts developed a balanced cantilevered solution based on the VARIOKIT System. The high degree of flexibility regarding the cross-section adaptation supported the rapid construction of the individual concreting sections while simultaneously ensuring optimized workloads.

girders. The carriageway slab was subsequently concreted in a second casting segment.

The PERI solution for forming the 19.60 m wide superstructure consisted of 4 VARIOKIT Balanced Cantilever Carriages which were used to realize 5.55 m long segments in each case. In the process, the system was flexibly adapted to suit the geometric cross- sectional changes and the varying, in part, very high loads with constantly load conditions. In particular, the planning took into account the cable arrangement of the segment suspensions in order to prevent collisions with the balanced cantilever equipment. In addition, 1.30 m high transverse ribs were realized together with the bottom slab and side walls of the hollow box

VARIOKIT minimized the required workload for each bridge section. For example, the independent moving procedure by means of the integrated hydraulics along with fully hydraulically-operable aligning and adjusting led to optimized cycle times. Furthermore, the detailed implementation plans and technical documentation ensured on-site formworking operations could be easily and efficiently carried out. The high proportion of system components from the VARIOKIT Engineering Construction Kit as well as the high availability of materials in the PERI rental park ensured a high level of cost-effectiveness.

For constructing the steel composite bridge, PERI engineers adapted the VARIOKIT System solution – formwork carriage and cantilevered brackets – to match the wide range of construction site requirements.

The 136 m long main crossing was constructed with the help of two VARIOKIT Steel Composite Formwork Carriages using the alternate sequential method within the planned time frame.

The VARIOKIT Formwork Carriage could be flexibly adapted to match the geometrical and static requirements which included 4.50 m cantilevers.

Both construction variants – formwork carriage and cantilevered brackets – were based on the VARIOKIT Engineering Construction Kit.

The expansion of the Lanaye lock facility required the new construction of a 200 m long road bridge complete with two 90° bends on the river banks.

The new 200 m long road bridge crosses the navigation channels of the newly expanded border lock facility between Belgium and the Netherlands at right angles. The S-shaped, 15 m wide bridge structure was realized using the steel composite construction method. With the help of two independently-operating VARIOKIT Composite Formwork Carriages, the 136 m long main crossing was constructed using the alternate sequential method within the ambitious time frame – in 13 casting segments with cycle lengths of 8 m to 12 m. The Formwork Carriages could be individually adapted to suit the geometrical and static requirements; this was particularly important as the bridge features an unusually large cantilever length of 4.50 m. In the area of the two bend radii – extremely tight at just 30 m – the PERI bridge solution inte-

grated the use of VARIOKIT Cantilever Brackets. In the geometrically and statically complex area of the circular columns, the brackets were arranged radially. Pressure supports transferred the concentrated loads of the external cantilevers into the available bridge piers. For this, system components from the VARIOKIT Engineering Construction Kit were complemented by MULTIPROP 625 Aluminum Slab Props to form the PERI complete solution. Apart from the use of standardized system components, pre-assembled formwork units delivered to the construction site accelerated the final assembly and ensured rapid and problem-free construction site use from the outset. The dimensionally-accurate fabrication took place at the PERI formwork assembly facilities in Weissenhorn and Düsseldorf. In addition, the site management was provided with ongoing support by Belgian and German PERI engineers from the beginning onwards.

For the new construction segment north of the central Serbian town of Čačak, two bridges were built within a short section: 232 m and 424 m long respectively, with individual spans ranging between 32 m and 42 m. Both structures have a 12.55 m wide and 2.20 m high superstructure with hollow box cross-sections which rest on massive reinforced concrete piers.

All the customized formwork elements for the superstructure – as done previously for the bridge piers – were pre-assembled by PERI formwork assembly team at PERI Serbia´s Simanovci facility near Belgrade and delivered ready-for-use to the bridge jobsite. This saved time-consuming assembly work on the construction site and ensured compliance with the extremely short construction schedule as well as a high quality of workmanship.

Construction of the reinforced concrete piers was carried out with CB/VARIO Climbing Formwork units. Adapted to meet the local conditions, the superstructure formwork was supported on PERI UP Framework Units and VARIOKIT Heavy-Duty Shoring Towers.

Ohio River Bridge “East End Crossing”, Louisville, USA Climbing formwork and shoring solution for complex pylons

Transport Engineering

From the bottom to the very top, each construction phase presented a particular challenge in terms of geometry and load transfer. For this, a German- American PERI project team developed and delivered a complete solution – on the basis of several formwork and scaffolding systems taken from the extensive PERI rental pool. VARIO GT 24, ACS and RCS Self-Climbing Formwork, the single-sided SCS Climbing System, VARIOKIT Shoring and the PERI UP Scaffolding Kit could be perfectly matched to one another – and ensured fast cycle sequences, high load-bearing capacities and a maximum level of safety during all stages of construction.

The 762 m long cable-stayed bridge over the Ohio River connects the states of Kentucky and Indiana. The new bridge is part of the nearly 14 km long road construction project which is designed re-route the Interstate 64 to the north of Louisville. The span of the main bridge section reaches 365 m, and the carriageway is carried by means of stay cables supported by two reinforced concrete pylons, each 90 m high. The lower, outwardly-inclined pylon legs are solidly constructed while in the upper segment, the pylon legs are inclined inwards and feature hollow box cross-sections. The cross-sections taper in an upwards direction, and a slight curvature causes a continuous change in the angle of inclination from casting segment to casting segment. Two 3.65 m thick cross beams – one at road surface level and the other at the upper pylon reinforcement – were also realized using in-situ concreting operations.

Customized system combination: above the VARIOKIT construction, PERI UP served as a shape-providing load-bearing system. TRIO Panel Formwork was used as side formwork while PROKIT Side Mesh Barriers mounted end-to-end provided a high level of safety when working at great heights.

Ideally matched systems form the basis for efficient and cost-effective construction operations. In particular for the realization of Chamiza bridge piers complete with massive pier heads up to 40 m high, PERI Chile provided materials and knowhow from a single source. The complete solution for formwork, supporting structure and access technology was based largely on standardized system components. The Chamiza Viaduct is an important section which connects Route 7 248

(Carretera Austral) in the south of Chile near Puerto Montt to the well-known Pan-American Highway, Route 5. Together, both highways form a 4,700 km stretch of road from the Peruvian border in the north almost all the way to Tierra del Fuego. Nine, up to 40 m high piers support the 410 m long bridge over a valley floor. For constructing the double piers with hollow box cross-sections, VARIO GT 24 Girder Wall Formwork and CB Climbing Platforms were combined to create craneable moving units. This

ensured – also in connection with successively height-extended PERI UP Stair Access – fast and safe work processes from the beginning onwards. The 4.00 m deep and up to 2.20 m high pier heads widen to more than 23 metres. For this, PERI engineers designed an extended cantilevered bracket solution to form a stable contact area and high load-bearing surface for the formwork on the basis of the VARIOKIT Modular Construction System. With the help of VARIOKIT system components, the loads

between the double piers could also be reliably transferred. Construction time was accelerated in particular by the fact that complete units were assembled on the ground which could then be lifted by crane into the intended position.

The CB Climbing System and VARIO GT 24 Girder Wall Formwork formed crane-movable climbing formwork units for the up to 40 m high double piers.

Also for bridging the main road situated in the ramp area of Chamiza Viaduct, PERI UP and VARIOKIT supplemented each other perfectly.

Mur Bridge S 35, Frohnleiten, Austria Large span with low weight and high load-bearing capacity

For the construction of the Mur Bridge, the modular VARIOKIT Heavy-Duty Truss stood out through its extremely high load-bearing capacity with a comparably low weight. In addition, the system components could be quickly installed and had a very flexible use. Heimo Egger Assembly Supervisor “The VARIOKIT heavy-duty truss system with the variable starting frame has set new standards in shoring operations. It reduces the amount of assembly work required especially for inclined supporting structures. The accuracy of fit as well as aligning the pairs of trusses also make a convincing case.”

The altogether 406 m long new bridge construction near Frohnleiten is the centrepiece of the S 35 motorway modernization project between the Bruck/Mur and Graz intersections. The new structure completely replaced the existing 60-year-old bridge which runs alongside. The pre-stressed concrete superstructure was designed as a 11.75 m wide T-beam cross-section complete with 2.50 m web heights. In spite of every respective 40 m spans of the two main bridge sections over the Mur, the construction of the superstructure on heavy-duty falsework by means of framework units was the most cost-effective solution. For this, a German-Austrian team of PERI engineers designed a customised project solution on the basis of standardized, rentable system components from the

VARIOKIT Engineering Construction Kit. The truss arrangement were flexibly determined in accordance with static requirements and featured truss spacings of 50 cm and 150 cm. In addition to the benefits of the project-specific planning and verifiable static calculations, the rapid availability of materials along with the briefing of scaffold erectors on-site by a PERI supervisor ensured short assembly times from the beginning onwards. In spite of the difficult boundary conditions – assembly and storage areas were extremely limited – this still allowed the construction schedule to be maintained. The lifting of the more than 37 m long coupled trusses by means of a mobile crane parallel to the existing bridge also required an experienced assembly team and perfectly coordinated working steps. A big advantage here was the low weight of the VARIOKIT Heavy-Duty Truss. This resulted in time and cost savings especially during the lifting procedure.

Modular shoring assembly with standardized connections and a minimum of tool usage: VARIOKIT system components were pre-assembled on the ground to form truss segments, placed in intermediate storage, and subsequently coupled to create 37 m long truss units.

As a competent partner, PERI provided customized solutions for constructing the piers, superstructure and pylons – adapted to meet a very wide range of requirements. The A5 motorway bridge which spans the River Drava, is altogether 2,500 m long. Two 75 m high A-shaped pylons carry the three main sections of the cable-stayed bridge with 220 m and 100 m spans respectively. The approx. 1,000 m long foreshore bridges on both sides are located in the flooding areas, and were realized using prestressed prefabricated beams on massive circular columns.

Ante Sabljić, and Anto Vranjković, Site Manager Pylons and Site Manager Superstructure “The VARIOKIT solution perfectly combines functionality, flexibility, reliability and faster assembly. As a result, we could optimally fulfil all technical requirements of the project. As usual, the PERI solution took into account all required details. In addition, the climbing formwork solution is not only very cost-effective but it also allows very short cycle times. The PERI technology used is very practical and we could also achieve a high standard of safety. We would also like to praise the support given to our construction team by PERI engineers before and during construction operations.”

The rectangular cross-section of the pylons is constantly changing – from 6.50 m x 3.50 m in the base area up to 4.00 m x 5.00 m below the converging pylon head. For the realization of this complex geometry, PERI engineers combined the CB and RCS Climbing Systems. On the front sides, the CB 240 Platforms together with the VARIO GT 24 Girder Wall Formwork were moved with the crane. For the up to 18° forward and reversed-inclined outer surfaces of the pylon legs, the rail-guided RCS Climbing Formwork provided the optimal solution whereby the units could be continuously climbed regardless of the weather and without requiring a crane by means of mobile hydraulic pumps. As a result, each of the 24 concreting sections could be completed within an average of 5 days. RCS, CB and VARIO GT 24 formed the ideal climbing combination for constructing the two bridge pylons.

The new 2,500 m long bridge carries the A5 motorway across the River Drava in east Croatia.

The foreland bridges are supported on 180 cm thick circular columns – here, too, PERI supplied a customized formwork solution.

By means of simple rollers, the formwork and supporting construction could be quickly moved as one unit to the next concreting section.

The PERI solution for constructing the parapets of both carriage ways was based on the VARIOKIT Engineering Construction Kit. The VARIOKIT Parapet Carriage was used for constructing the external, large-sized parapets. As the loads were transferred via a gallows construction, anchoring in the superstructure was not required. For forming the parapets on the inner sides of the cariageways, VARIOKIT System Components were combined with the PERI UP Modular Scaffolding.

The “Place de Martyrs”metro station in the Algerian capital boasts some very impressive dimensions. For this, the PERI formwork carriage construction on the basis of the VARIOKIT engineering construction kit was customized to optimally meet the specific jobsite requirements, and was hydraulically operated.

254

144 m long and 23 m wide, the “Place des Martyrs” is one of the largest subway stations in the world. It is the northernmost but also most centrally- located Station – as well as closest- situated to the harbour area – of the extensive Metro expansion project within the city centre with numerous mosques and palaces as well as being directly below the historic old town (Kasbah). In a period of 10 years, the metro network of the Algerian capital is to be expanded and modernized from the current length of 9 km to a total of 55 km.

The formwork and scaffolding solution for the entire construction project was developed by a team of PERI engineers from Algeria, Portugal, and Germany. In addition to the VARIOKIT formwork carriage construction for the “Place de Martyrs”, a second project formwork carriage with a 9.30 m radius was utilized for the realisation of the “Ali Boumendjel” intermediate station. Two other project-specific tunnel formwork carriages were used for the construction of the 1,450 m long tunnel with its 9 m arch diameter.

The imposing arch width of 23 m in the middle section, tapers in the northern and southern directions resulting in 16.50 m widths respectively. PERI engineers developed a formwork carriage construction based on the VARIOKIT engineering construction kit in order to be able to cost-effectively realize both cross-section variants whilst using the same system components and formwork segments. Due to the relatively short 5.10 m concreting cycle lengths, special attention was paid to the design of the bracing.

Nordhavnsvej Tunnel, Copenhagen, Denmark Tunnel know-how for a cost-effective system solution

Brian Andersen Foreman “The main reason why we chose PERI was, that we were sure to have a formwork supplier, that can always deliver the material and has the necessary technical know-how to design all solutions for this kind of project.”

Transport Engineering

PERI engineers developed a customized formwork carriage solution for the Copenhagen tunnel jobsite using components taken from the VARIOKIT Construction Kit and supplied formwork and scaffolding from one source. Around 620 m of the altogether 1.65 km long Nordhavnsvej infrastructure project runs underground. In depths of up to 22 m, the two separate tunnel tubes each have 2 vehicle lanes. The double-tube tunnel with a rectangular cross-section was realized using the cut-and-cover construction method. PERI planned and supplied a tunnel formwork solution with wall formwork in advance and a trailing slab formwork carriage. With the customized project solution, the construction crew maintained a 3-week cycle for each of the 25 m long casting segments. Bottom slab and tunnel walls were formed with TRIO Panel Formwork; in part single-sided against the sheet piling of the excavation pit. For this, TRIO elements were connected to form large-sized units which could be moved very quickly by crane. For the subsequent construction of the 80 cm thick slabs, 4 slab formwork carriages – each 13.50 m Long – on the basis of the VARIOKIT Engineering Construction Kit were used. In order to concrete the respective 25 m long slab sections,

The “Nordhavnsvej – Vej- og Tunnelentreprise” major infrastructure project connects the North Harbour in Copenhagen with the Helsingør motorway. The 620 m long tunnel route runs through a very densely built-up inner city area and also crosses a busy railway line.

2 formwork carriages were coupled one behind the other. A hydraulic solution simplified and accelerated the lifting and lowering of the tunnel formwork carriages. A clever solution: the subelement for the haunch to the centre wall could be folded down by means of spindles; for this, the VARIOKIT construction was equipped with cantilevered working platforms. The fact that well over 90 % of the PERI Formwork Carriage solution consisted of rentable core and system components ensured maximum operating efficiency.

The VARIOKIT Formwork Carriage solution took into account a 4.30 m wide and 4.00 m high access opening for unimpeded construction site deliveries as well as hydraulic support for simple lifting and lowering.

256

The working scaffolds and access stairways to the working areas were also part of the PERI formwork and scaffolding concept. PERI UP Stairs securely mounted on the formwork carriage served as integrated access to the slab formwork. For the walls, 7.50 m long PERI UP reinforcement scaffold complete with transportation wheels was quickly moved to the next place of use each time. This saved valu able crane time and also allowed moving operations to take place in the area of crossing the railway line even when no crane was available. Contractor Consortium E.

With help of the VARIOKIT Tunnel Formwork solution, 25 m long sections of the tunnel arch could be concreted in regular 4-day cycles.

The hydraulic operability of the VARIOKIT Formwork Carriage allowed fast and accurately-repeated shuttering and striking operations.

The VARIOKIT-based tunnel formwork system solution ensured that a 1,545 m long stretch of the Tauern motorway disappeared under an enclosure-type structure after only a very short construction period.

progress. Foundation formwork, centre wall formwork carriage and the trailing arched formwork carriage were perfectly matched in order to complete a total of 125 casting segments, each with 12.50 m standard cycle lengths. 2cycles respectively could be formed and concreted in one working step.

In peak periods, up to 40,000 vehicles use the A10 Tauern motorway every day. A comprehensive package of measures has considerably eased the situation for the Zederhaus community. Alongside the passing road traffic, the designated stretch of motorway was in part relocated and subsequently covered by a 1.5 km long tunnel structure. In almost 4 years, 405,000 m³ of earth was moved followed by the installation of 140,000 m³ of concrete and 7,300 t of structural steel. Only 18 months was available to realize the shell construction. The construction of the double tube with arched cross-sections was carried out using the cut-and-cover method with the help of the VARIOKIT Engineering Construction Kit. Construction work on the second tube began at the start of 2016, in the planned time frame after completion and release to traffic of the tunnel on the mountain side. On the basis of standardized system components, the PERI complete solution ensured smooth construction 258

The hydraulic support for lifting and lowering the formwork carriage as well as for folding of the wall elements proved to be especially time-saving. The large-sized external formwork was moved with the crane. Formwork units were accurately pre-fabricated in the PERI assembly facility. The reduced installation efforts on the construction site and ensured fast operational readiness from the start. The detailed sequential implementation concept took into consideration the integrated construction of the emergency and inspection bays at distances of 100 m as well as changing crossfalls and axis radii. As the standard VARIOKIT Formwork Carriage could also be used for the widening of the 70 m long breakdown bays in the the tunnel centre, this provided additional time and cost benefits.

Hongkong-Zhuhai-Macao Bridge (HZMB), China Portal formwork carriage for tunnel transition in architectural concrete quality

Transport Engineering

Meng Fanli, Project Leader West Island Lin Ming, Project Director Liu Haiqing, Project Leader East Island “PERI played a decisive role in realizing this once-in-a-century structure; tunnel entrances and breakwater were extremely challenging due to maintaining the highest quality requirements. The formwork could be easily moved and provided the best possible safety and first-class architectural concrete quality. We came to appreciate the professional engineering, service and the striving of the PERI engineers for perfection.”

The construction of the high side and centre walls as well as the breakwater for two transitional structures was carried out using mobile PERI Portal Formwork Carriages – with a fast cycle sequence and high quality of workmanship. The 35 km long Hongkong-ZhuhaiMacao road connection is located in the area of the approach flight path of the Hong Kong International Airport, Chek Lap Kok, in an underwater tunnel. This 6 km long immersed tunnel had already been successfully built with PERI know-how – the shell construction for the east and west transitional structures was the next stage to be completed. For this, two artificial islands were created in the southern Chinese Pearl River Delta.

300 m long ramp structures with high walls in architectural concrete quality serve as the entrance and exit points of the 6 km long HZMB tunnel.

Side walls and centre wall were constructed with the help of three PERI formwork carriages – with a fast working speed and high quality of workmanship.

6 lanes lead into the two tunnel portals with a 3 % longitudinal gradient. The approx. 300 m long side walls of the up to 56 m wide ramp structures feature massive 2.50 m wall thicknesses. In addition, both driving directions are separated in the tunnel exits by a centre wall which will subsequently carry the roofing construction. The up to 15.50 m high reinforced concrete walls were to be realized in SB 4 architectural concrete quality with a clearly structured joint and tie arrangement as well as ensuring water impermeability on a sustained basis.

By including system components taken from the VARIOKIT Engineering Construction Kit, VARIO Girder Wall Formwork system and SK anchor t echnology, thePERI concept provided the most cost-effective and efficient solution option. As a result, concreting could be carried out in regular cycle lengths of 15 m while the entire height of each wall section was constructed in one pour.

The construction of the extensive architectural concrete walls was carried out largely without crane support. For quick, safe and simple execution, PERI engineers planned mobile portal wall

Msheireb Metro Station, Doha, Qatar Major construction site at a depth of 40 m

An individually tailored system concept and continuous on-site support facilitated the fast construction progress of the Msheireb Station, the key element of Doha's new metro system. The Msheireb subway station is situated in the heart of Doha and is the lynchpin of the ultra-modern metro system currently under construction in the capital of Qatar. This is where the three most important connections converge: the “Gold Line”, “Red Line” and “Green Line”. By 2020, 82 km of tunnel routes and 25 stations will connect the residential and commercial centres with the suburbs and World Cup stadiums. In the final phase, the Doha metro system will feature a total of four lines and nearly 100 stations. The metro station is located at a depth of 40 m and has 4 main levels. In order to effectively realize the 200 m long and 180 m wide major interchange with its massive component dimensions within the given construction period, PERI planned and delivered the formwork and scaffolding systems.

Transport Engineering

The complex structural geometry, with up to 3 m thick reinforced concrete slabs and wall thicknesses reaching 2 m, required a customized implementation concept. Within a very short space of time, 10,000 m² of wall and column formwork as well as 150,000 m³ of shoring were delivered to the construction site. For forming the massive walls, the VARIO Girder Wall Formwork system was used. For the single-sided forming of the up to 9.50 m high walls, SB Brace Frames supplemented the PERI formwork solution. For the higher wall sections, VARIO together with CB Climbing Platforms formed crane-movable climbing units. The tie holes could be reliably closed with the help of the DK Tie System. The shoring concept developed by PERI engineers for transferring the high loads is based on proven PD 8 Shoring Towers, MULTIPROP Aluminium Slab Props and PERI UP Flex Modular Scaffolding System. Here, the 25 cm scaffold grid allowed easy adjustment of the PERI UP Standards to suit the wide range of load requirements.

Capitol Hill is one of two subway s tations constructed as part of the rapid transit project for the Greater Seattle region. The new station is almost 18 m deep and over 100 m long. Huge steel-composite tubes with 1.00 m and 1.50 m diameters respectively brace the underground structure on two levels. A very experienced team of PERI engineers from USA and Germany developed a cost-effective formwork and scaffolding concept with detailed solutions for all stages of construction, and was based on rentable system components available at very short notice. Thus, walls and reinforced concrete beams could be monolithically constructed in one pour. This avoided the need for construction joints and resulted in assembly cost savings.

designed as a two-piece construction. As a result, it was possible to use the top half of the carriage for the remaining two levels after completion of the lower level. These were realized using 6 concreting cycles each time with heights of almost 5 m and 4 m respectively. The formwork carriage was completely hydraulically operated, and moved along on the reinforced concrete edge beams of the respective lower level by means of heavy duty rollers. HD 200 heavy-duty props were used as lateral supports in order to safely transfer the additional loads from the formwork carriage and the next concreting cycle. At the same time, the VARIOKIT unit served as temporary support during the assembly of the huge steel tubes used for bracing. In order to transfer the high loads resulting from the concreting operations for the 1.22 m thick reinforced concrete slab into the longitudinal edge beams, the formwork carriage was adapted to suit the changed load situation. However, the hydraulic handling and easy movability of the formwork carriage unit were still available.

Fathi Abdul Muti Deputy Project Manager “We met all milestones ahead of schedule which can only be achieved with the right partner and solutions. PERI prove to be very responsive and handled the challenges of such a huge project like ours very well.”

Delivery of enormous amounts of materials at short notice as well as competent engineering with related formwork and scaffolding planning made a convincing case during the construction of the airport terminal of unparalleled proportions. For ensuring strict adherence to the schedule, the comprehensive on-site support provided by a permanently assigned PERI project team consisting of very experienced supervisors and project managers played a key role; work and logistical processes were coordinated in close collaboration with the site management. The new X-shaped Midfield Terminal was built between the north and south runways of the Abu Dhabi International Airport where 65 wide-bodied commercial aircraft can be accommodated 266

at the four piers and up to 30 million passengers can be handled annually. In peak periods, up to 17,000 workers were working in shifts around the clock on the giant construction site. For maintaining the tight schedule, more than 1,000 cubic metres of concrete had to be formed every day. As a result, around 700,000 m³ of concrete and 200,000 t of steel were processed in a mere 18-months construction period.

Centrepiece of the Midfield Terminal is the over 50 m high passenger terminal, the so-called Central Processor, for which PERI planned the formwork and scaffolding systems and delivered huge amounts of material in a short period of time. The concept of the PERI engineers was flexibly adapted to suit the different ground plan geometries and slab heights of the 7-storey high terminal complex.

More than 60,000 PD 8 Frames were assembled to form 6 m to 10 m high shoring towers which reliably accommodated the high loads from the floor slabs and beams, and could be re-positioned without requiring a crane for the next use each time. Approx. 6,200 slab tables were in continuous use on the construction site – with almost 65,000 m² of formwork materials, this was an area almost as large as 10 foot-

ball pitches. The slabs together with the massive, mostly 0.85 m wide and 1.10 m high beams were constructed in one pour. The use of lightweight LIWA Panel Formwork elements as side formwork accelerated site operations due to easy shuttering and striking by hand and also reduced formlining requirements.

4,000 massive, reinforced concrete columns with a wide range of dimensions were constructed with the help of VARIO GT 24 Column Formwork as well as project-related SRS Circular Column Formwork elements. VARIO GT 24 Girder Wall Formwork reliably accomodated the high concrete pressure of the up to 12.50 m high reinforced concrete walls.

Water retaining structures serve to promote the utilization of water as well as the regulation and control of stretches of water in order to create or protect habitats – whilst taking into consideration the environment and resources. Water construction projects are often associated with complex structures comprised of massive structural elements. For the execution of the construction work, this often means single-sided forming operations without the use of ties. For also ensuring awatertight execution over the long term, the selection of the appropriate anchor and sealing system is frequently of particular importance.

The well-thought out climbing and supporting frame construction for the overflow area at the top of the dam were also comprised of PERI system components: SB Brace Frames and system components taken from the VARIOKIT Engineering Construction Kit formed large-sized platforms for the up to 8.65 m cantilevered casting segments. MULTIPROP Shoring Towers and SLS Heavy-Duty Spindles supported the inclined VARIO GT 24 Formwork Units.

The 108 m high and 275 m long dam has a very complex geometry. By means of a customized formwork, scaffolding and service concept, it was possible to maintain the very tight construction schedule and keep within the planned budget.

With a package of solutions consisting of formwork, scaffolding, logistical and technical services provided throughout the project, PERI engineers effectively supported the construction of the dam and the associated pumped storage power plant. The double-curved dam wall has a height of 108 m while the length of the 5 m wide dam crest reaches 275 m. The main focus here was to coordinate the wide range of formwork configurations, with a tight schedule and high

material requirements in particular to take into consideration. In addition to planning the formwork and scaffolding solution for the complex geometries and high loads, strict compliance of the construction schedule and staying within the planned budget for the imposing dam project were the major challenges. For ensuring smooth construction progress, all planning, logistical and formwork assembly processes were therefore precisely coordinated by the PERI project manager on site and adapted to match the actual construction sequence.

PERI UP was used for a range of shoring and working scaffolds as well as the access solutions. PERI UP Stair Towers with erection heights of up to 55 m provided quick and safe access means to the working areas.

The combination of the SCS Single-Sided Climbing System and VARIO GT 24 Girder Wall Formwork was ideally suited to accommodate the single-sided load transfer without formwork ties. Due to the high load-bearing capacity of the SCS Brackets, large-sized and crane-movable units could be formed. SCS modular concept with multi-piece brackets allowed optimal adjustment to match the structural geometry which featured different inclinations – and ensured horizontal alignment of the 1.90 m wide working platforms at all times. 271

The SCS Climbing System could be flexibly adapted to suit the variable inclinations and reliably transferred the high loads from the fresh concrete pressure into the previous casting segment.

The overflow funnel of the Bagatelle Dam features a complex curved shape. Based on system components and 3D formwork units, the climbing formwork solution was individually adapted by PERI specialists to accommodate the structural geometry and the single-sided load transfer. Although the island nation of Mauritius in the western Indian Ocean registers abundant rainfall, the rainwater quickly flows – mostly unused – into the sea due to the relatively small surface area of the island as well as the numerous steep gradients. The Bagatelle Dam Project has improved the water supply with the realization of this approx. 14 million m³ storage capacity. A 2.5 km long and up to 48 m high dam transforms a tributary of the Grand River North West into a reservoir at almost 400 metres above sea level. Construction of the overflow funnel for the flood spilway was supported by PERI engineers with a 3D formwork solution. The diameter of the circular shaft construction featured in the ground plan widens from 8 m to 27 m in at the crown of the funnel in the form of a chalice – outside with a uniform and internally with variable inclinations respectively. For realizing the complex geometry, SCS Climbing

Brackets along with three-dimensional formwork units based on VARIO Girder Wall Formwork elements were used. With the SCS Climbing System, the forward and reverse-inclined sections could be concreted single-sidedly, i.e. without ties. The adaptation to suit the given geometry was no problem; in addition, the bracket platforms always ensured horizontal working areas and access points even when having to deal with differently inclined walls. The formwork for the funnel walls with curved surfaces on all sides was individually manufactured. The detailed 3D planning and dimensionally-accurate CNC timber formers were realized in the formwork assembly facility at PERI headquarters in Weissenhorn. Final assembly and installation of the formlining took place on the construction site – under the expert guidance of a PERI supervisor, and based on VARIO basic elements. An integral part of the reverse-inclined climbing formwork solution were the inner-mounted brackets which ensured that the elements could be easily and quickly shuttered and stripped with the crane.

In order to ensure that the ambitious hydraulic engineering project on the Nile will begin operations within the planned time frame, PERI formwork and scaffolding systems as well as competent on-site support provide easy handling and fast cycle sequences. The new barrage between Luxor and Cairo replaces the old existing dam

built in 1902 which is located 400 m further downstream. The weir system supplies the 350 km Ibrahimiyya main irrigation canal and thereby 700,000 hectares of farmland with water from the Nile – a valuable natural resource for 1 million farmers and the Egyptian population. Integrated in this complex hydraulic engineering project is a 32 MW hydroelectric plant for generating electricity, two locks and a bridge

crossing. With a construction period of 5 years in total, more than 1,700 skilled personnel are working to achieve the planned 2017 completion date. Altogether, 8 sluiceways with 17 m widths respectively and a maximum damming height of 4 m ensure that a minimum 445 m³/s of water from the Nile can be discharged into the canal. In addition, the extensive concreting

work includes two locks, each 120 m long and 17 m wide, as well as construction work for the power plant. For forming the mainly massive reinforced concrete elements, PERI has provided the most cost-effective solution based on VARIO Girder Wall Formwork and the CB Climbing System. Over 8,000 m² of VARIO Girder Wall Formwork is in daily use at this major

construction site. In combination with the CB Climbing Platforms, the formwork and scaffolding can be moved as a large-sized unit with the crane. Here, both systems can be flexibly adapted for the construction of the challenging structural geometry and accommodating the required fresh concrete pressure. For accurate realization of the curved elements, customized formwork units within the VARIO elements

are being used; in addition, the subsequent installation of the technical equipment requires compliance with very high quality standards. The PERI formwork solution is complemented by planned needs-based use of PERI UP and PD 8 Shoring Towers.

Hisham Khattab Site Manager “For such projects, the choice of the right formwork system is a very important decision. After very careful consideration, we decided in favour of PERI due to the high level of safety, easy handling and fast cycle sequences. As expected, the PERI team has provided us with very professional support.” VARIO Formwork, CB Climbing Platforms and PERI UP access technology guarantee easy handling along with a high level of safety.

The heightening of the dam at the Blue Lake ensures an autonomous power supply for the citizens of Sitka in the US state of Alaska. An important part of the PERI climbing formwork solution was the transfer of the high loads resulting from a massive cantilever in the area of the dam crest.

Difficult site accessibility and a complex geometry presented the construction team with major challenges. The formwork concept was based on the CB and SCS Climbing Systems and was perfectly complemented by the use of VARIOKIT system components.

The VARIO formwork for the vertical edge areas was climbed on CB Platforms. For the spillway section with its massive cantilever, the SCS Climbing System was combined with SB Brace Frames and MULTIPROP Shoring Towers.

The construction of the massive, 2.44 m thick and rounded reinforced concrete wall with a 35 m radius, in particular, required a formwork concept that was exactly matched to the construction progress and challenging structural geometry. The PERI implementation solution was based on a number of different systems which could, however, be combined with each other. For realizing the vertical edge areas, the CB Climbing System along with VARIO GT 24 Girder Wall Formwork were used. F or this, platforms and formwork could be moved 276

with the crane as large-sized units respectively in regular concreting cycles heights of 3.05 m. On the dam itself, the overflow structure has a length of around 40 m. Here, the crest of the dam cantilevers 6.34 m in a downstream direction. Transferring the enormous loads was carried out by means of horizontally-positioned, connectable SB Brace Frames. As a result, an intermediate level could be formed which simultaneously served as a generously-dimensioned working platform and high load-bearing basis for sup-

porting MULTIPROP Shoring Towers. simultaneously. SCS Climbing Formwork units ensured the efficient transfer of loads during the single-sided forming operations; here, the brackets could be flexibly adapted to match the complex geometry.

Nant de Drance Pumped-Storage Power Plant, Martigny, Switzerland Modular formwork concept for underground large-scale construction site

Water Retaining Structures

Ulrich Anschütz Site Manager “My compliments to the Swiss PERI team and to MCE for this extraordinary, customized formwork solution. With up to 300 m³ of concrete per section, we only had a minimum of deformations.”

Contractor ARGE GMI (Groupement Marti Implenia), Marti Tunnelbau AG and Implenia Bau AG Field Service PERI AG Switzerlan, Ohringen and MCE GmbH, Eschenz

The construction of the underground machine cavern as well as two intake structures required an elaborate formwork concept along with competent jobsite support The Nant de Drance pumped-storage power plant, with a total output of 900 MW, will begin operating at the end of 2018 after 10 years of construction. The power plant is being built to a large extent underground at a height of 1,700 m above sea level between the Emosson and Vieux Emosson reservoirs. For this, 1.7 million m³ of rock will be removed while creating a tunnel and gallery system totalling 17 km long. At the Nant de Drance pumped-storage power plant, changing from pump to turbine operations can be carried out within minutes. For the construction work, PERI and MCE offered a well thought-out formwork concept, continuous on-site support as well as assembly support by a supervisor.

278

An integral part of the PERI solution was the formwork carriage and wall formwork for constructing the two intake structures with up to 3 m thick reinforced concrete slabs.

Dimensionally-accurate prefabricated formwork elements allowed the transition from circular to square-shaped tunnel cross-sections.

The machine cavern for the installation of the pump turbines is 194 m long, 32 m wide and 52 m high, and is one of the largest underground constructions in Europe. For the final excavation work, the arched slabs along with the abutment beams were concreted in advance. In close cooperation with MCE Engineering, PERI Switzerland planned and delivered a modular formwork carriage solution. The construction of the 32 m wide and initial 12.50 m high tunnel cross-section was carried out in 18 casting segments, each with a

10 m cycle length. For fast cycle sequences, the tunnel formwork carriage was equipped with an electric drive system which meant it could be hydraulically raised and lowered. The lateral anchoring clamps were likewise concreted in advance with the help of a hydraulically operated PERI formwork carriage construction. An important feature of the project was also the intake area on the higher Vieux Emosson reservoir at a height of 2,200 m. For the two intake structures and headrace tunnels, PERI likewise provided efficient formwork carriage solutions. The varying longitudinal gradients up to 12 %, the transition from a circular to a square-shaped tunnel cross-section as well as the trumpet-shaped portal widening were taken into consideration here. For the extensive surface and underground construction work, TRIO Panel Formwork in connection with SB Brace Frames and Climbing Brackets were also used in order to form and concrete the up to 14 m high walls.

Yuri Cherniak and Andrei Smouzh Site Managers “The VARIO, TRIO, MULTIPROP and PERI UP systems used on our jobsite allowed us to realize very challenging concrete structures in superb quality and the shortest possible construction time. Many thanks to PERI for many years of partnership-based cooperation.”

The power plant construction of the Daugava barrage required extensive concreting work. The formwork and scaffolding concept was based on versatile system equipment, detailed execution and cycle planning as well as competent construction site support. The 22 MW hydroelectric power station near Polotsk in the north of Belarus is the first one of a total of four planned barrages on the Daugava river. 140,000 m³ of concrete was used in 6 years of construction on the 61 hectare construction site. The complex design of the building with its massive reinforced concrete structures and heights

280

of up to 29 m placed enormous demands on all project participants. The proven wall TRIO and VARIO Formwork Systems, MULTIPROP and PERI UP modular load-bearing systems as well as CB Climbing Platforms and VARIOKIT System Components formed the basis for the PERI formwork and scaffolding solution. These fulfilled the wide range of requirements in all phases of construction and, in particular, ensured the reliable transfer of heavy loads during the realization of the cantilevered concrete components. Project-specific 3D formwork ensured a high degree of dimensional stability for the discharge structures.

Through the very detailed PERI cycle planning, optimization of the system utilization was achieved. Thus, material requirements and costs could be minimized and simultaneously boost efficiency. For example, wall formwork elements were initially used single- sided then subsequently double-sided and anchored, as well as utilized as tunnel formwork. System components of the tunnel formwork were used, in turn, in the load-bearing system for the pier cantilevers. The basis for this was provided by the flexibility and modularity of the PERI systems in combination with technical support by PERI specialists throughout the entire construction phase.

Industrial Structures includes the new construction, modernization and maintenance of structural facilities in industry. Planning and execution is determined by the demands of current and future production processes. The functional and economic aspects outweigh any architectural requirements which usually are of secondary importance. The actual execution is often associated with stringent safety regulations. Furthermore, structural work to be carried out and technical equipment installation also simultaneously require close coordination of the construction sequences. Approvals, type tests and technical documentation serve to verify the quality and reliability of the system equipment used.

Dedusting System for Blast Furnace 9, ThyssenKrupp, Duisburg, Germany PERI UP and VARIOKIT: 2 systems – 1 grid

Scaffold Contractor Intering GmbH, Scaffolding Department, Leuna Field Service PERI Germany, Leipzig and Weissenhorn

For the execution of the insulation work, the consistently high safety standard of the PERI UP Flex along with the almost unlimited combinability with VARIOKIT system components convinced scaffolding erectors and users alike. ThyssenKrupp Steel Europe operates four company-owned blast furnaces at the Duisburg facility. For the most recent extensive modernization measures, Blast Furnace 9 was taken out of service and brought in line with the very latest technical standards. Part of the work included the re-insulation of the casting house dedusting system. For this, PERI scaffolding specialists planned a project-specific working scaffold which was based on two compatible modular construction systems: PERI UP and VARIOKIT. Both systems follow a uniform metric basic grid. The PERI UP Flex Modular Scaffolding provided optimal working conditions for all insulation work. The high degree of variability allowed any adjustments in 25 cm increments – resulting in completely safe working platforms.

284

Industrial Structures

The loads from up to five additional scaffolding levels were transferred into the external scaffolding via the supporting intermediate level which consisted of VARIOKIT core components. PERI UP therefore served as both working scaffold and shoring.

Through the consistent use of system scaffolding components, the decking areas were free of gaps and tripping hazards. Guardrails and toe boards could be installed end-to-end also without any gaps. Safe and quick access to all levels was provided by integrated stair towers complete with 75 cm wide aluminum flights of stairs. In order to access the plant sections to be worked on via the non-supporting flat roof, a girder grid for transferring loads was integrated into the PERI UP scaffolding solution at a height of 12 m – formed using rentable steel walers taken from the VARIOKIT Engineering Construction Kit. Due to the 12.5 cm grid system, the VARIOKIT could be ideally combined with PERI UP Flex. Standardized connecting means facilitated continuous installation with system components – without any time-consuming adjustment work with tubes and couplers.

Heiko Neie Supervisor “With PERI UP Flex, the most suitable grid dimensions can always be realized and it is 100 % compatible with other PERI system components. And the integrated protection against lifting in the steel decks fully complies our high safety requirements.”

Modular supporting systems made it possible to easily adapt to the complex building structure.

The PERI shoring concept for transferring the high loads was based on standardized construction kit systems: MULTIPROP, HD 200 and VARIOKIT. With the help of the PERI UP Modular Scaffolding System, the required access means was realized.

A PERI shoring combination for transferring high loads – adapted beforehand to suit the complex building geometry – facilitated the efficient construction of the massive reinforced concrete components for the power plant. The new Block 11 at the Kozienice facility is the largest-fired coal power plant unit in Europe with an output of 1.075 MW, and worldwide one of the most modern of its kind. For the structural work on the turbine foundations, massive reinforced concrete components had to be realized. This required the transfer of very high loads from great heights, combined with the highest safety and quality requirements.

286

PERI Poland developed and delivered a comprehensive formwork and scaffolding solution that was perfectly matched to the strictly scheduled construction process with tight execution deadlines. In particular, the wide range of load supporting systems made it possible to form and concrete the complex building structure within the given tight dimensional tolerances – from the 5.50 m thick bottom slab and massive columns and beams through to the 3.30 m thick foundation slab at a height of over 20 m. With the combination of MULTIPROP Shoring Towers, HD 200 Heavy-Duty Props and VARIOKIT Heavy-Duty Shoring Towers, the detailed shoring con-

cept could optimally fulfil the wide range of requirements. The use of standardized system and connecting components ensured short assembly times – rapid availability and high level of cost-effectiveness was guaranteed through the immediate availability in the PERI rental parks.

Flexibility during modernization operations Parallel to the construction of Block 11, the existing infrastructure of the

Kozienice power plant was also modernized. For example, Blocks 1-8 were equipped with a new flue gas desulphurization system. For carrying out the insulation work, safe working plat-

forms for up to heights of 30 m were realized with the help of the PERI UP Flex Modular Scaffolding System.

Marcin Tymiński Site Manager “For rapid realization of the project, we found the right scaffolding provider in PERI. PERI Poland demonstrated great commitment during the technical and logistical support.”

Northwest Redwater Project (NWR), Edmonton, Canada Time and cost factor lowered, safety levels increased

The detailed 3D scaffold planning along with early consultation and coordination with all project participants increased both work safety and efficiency. In addition, PERI supported the project management with a control software for large-scale projects and optimized the interlinking between scaffold planning and execution.

Safe working platforms: the consistent use of system components not only accelerates the assembly work required on the scaffolding. Through the gap-free installation with system decking, this means there are no overlapping planks thus avoiding the presence of any tripping hazards during later use.

Project-specific PERI UP industrial scaffolding solutions accelerate work operation speeds and increase the level of safety.

For the construction of a Canadian industrial plant, the PERI UP Scaffold System and integration of 3D scaffold planning at an early stage reduced the time and cost factor while simultaneously increasing safety levels.

PERI´s North American scaffolding specialists are planning and supplying PERI UP industrial scaffold solutions as well as ensuring the on-time availability of correspondingly large quantities of materials. 1,500 t of scaffolding equipment is in daily use while around 1,500 people are working on the construction site at peak times. Safety is always of paramount importance: one of the most important objectives for all project participants is to ensure that no accidents occur during the estimated 1 million working hours.

the perfectly coordinated metric grid arrangement of the scaffolding components, plant sections can be systematically scaffolded in 25 cm increments without any on-site tube-coupler assembly, and thus form very safe working platforms. Furthermore, the detailed 3D scaffold planning with PERI CAD on the jobsite allows solutions to be approved in advance with all the project partners. As a result, all problem areas can be identified at an early stage and the working scaffold is then optimized for further usage. This avoids improvisations during the actual scaffolding phase, thus accelerating operation speeds and providing maximum safety for site personnel.

North-east of Edmonton/Alberta, the world's most advanced oil sand refinery is currently being constructed. The facility will produce 150,000 barrels per day, i.e. close to 2.5 million litres of oil. Since 2013, plant components have been installed on the 2 km² area, and the first of a total of three sections will become operational in the autumn of 2017.

Integrated staircases allow convenient and rapid access to all scaffold levels.

288

For this, PERI UP provides system-integrated advantages during scaffold assembly and use. For example, due to

In addition to the system-related assembly- and safety advantages provided by PERI UP, the competent on-site Project support is an important factor for realizing time and cost reductions.

Stanari Thermal Power Station, Doboj, Bosnia-Herzogovina Test of strength for formwork and scaffolding

The base area of the turbine structure measures 30.50 m x 12.00 m, and is characterized by its massive walls, beams and slabs. PERI UP Modular Scaffolding formed the shoring for up to 5.30 m high slab in the turbine building. The legs were simply bundled together in areas of high load concentrations – the system could therefore be optimally adapted to suit the loads.

9 circular concrete piers with 3.60 m external diameters and 40 cm wall thicknesses carry the steel platform for the air-cooled condensator at a height of 26 m. On each pier, 12 CB 240 Climbing Brackets carried the customized VARIO GT 24 Wall Formwork elements. Construction of the pear, including the pier head, took place in 9 cycles using 3.00 m concreting heights respectively. PERI UP Stair Towers provided safe access to the designated working areas.

desulfurization and dust separation. Approx. 3,000 people were involved in the construction of the power plant over a time frame of 45 months with trial operations taking place at the end of 2015.

PERI´s contribution for realizing the 300 MW power plant was a project- specific overall concept – consisting of formwork, scaffolding and engineering from a single source. With a just-in-time supply of materials, detailed plans and static calculations, PERI engineers continuously provided on-site support for the implementation and thus compliance with the short construction period. The Stanari coal-fired power plant produces around 2 million megawatt hours (MWh) of electricity annually and fully complies with EU environmental standards by means of continuous waste gas treatment including flue gas 292

PERI planned and supplied the formwork and scaffolding systems for two construction areas: a climbing formwork solution for the 9 piers of the steel platform for the condensator as well as a combination consisting of a stable shoring construction and complex arched slab formwork for the turbine building. The heavy massive components with a high degree of reinforcement as well as the large heights to be accommodated placed exacting demands: high load-bearing capacity, great flexibility in the application and the provision of large amounts of material in a short construction schedule. Atthe same time, the formwork and scaffold constructions for the realization of the power plant were to be individually calculated and developed. Thus, the complete turbine structure is, for example, characterized by its very impressive dimensions: the

c olumns have a cross-section of up to 1.40 m x 2.10 m while the beams measure up to 2.10 m x 5.30 m. Moreover, the up to 5.30 m thick slab also featured arched sections in some areas. PERI engineers developed an 11.60 m high shoring solution on the basis of the PERI UP Modular Scaffolding System. Through the 25-cm grid arrangement, the leg spacings could be optimally adapted to suit the load requirements found in the different areas. For the flat slabs, MULTIFLEX Girder Slab Formwork provided the necessary versatility; for the arched construction, a supporting structure comprised of rentable VARIOKIT system components was formed.

Luka Popržen and Miroslav Usorac Project Managers “PERI developed a very safe and fast formwork solution for us. The technical solution together with the excellent assembly plans, as well as the easy application and high load-bearing capacity of the system, were particularly helpful in ensuring that the in part complex formwork and concreting work could be efficiently realized. From the planning and static calculations through to on-going support during the construction phase, PERI proved that its service is of the highest quality.”

Building redevelopment includes the conversion as well as the refurbishment and modernization of existing buildings from a value-preserving and urban development point of view. Building redevelopment is increasingly gaining importance – from energy-conserving renovation of a detached house or the modernization of municipal buildings through to upgrading an industrial site which is then used for a new purpose. Construction measures for gaps between buildings on mature street facades are also included here, frequently under the aspect of preservation issues. In order to be able to also work quickly in restricted spaces and without a crane, the equipment used should be lightweight and preferably easy to move by hand. As a rule, supporting structure concepts and working platforms are required on a project-specific basis, respectively adapted to match all geometrical and static requirements.

Hotel Le Royal, Luxembourg Cantilevered system combination for refurbishment measures

Building Redevelopment

Cantilevered platforms accelerated the complete refurbishment of the Luxembourg luxury hotel. The customized project solution was based on two compatible PERI Modular Construction Systems – VARIOKIT and PERI UP.

The planning and assembly involved a total of 8 working platforms using two PERI Modular Construction Systems: VARIOKIT and PERI UP. In addition, MULTIPROP Aluminum Slab Props reliably supported the RCS Climbing Rails – which ran inwards through the window openings – against the floors

and slabs. Externally, the cantilevered VARIOKIT Supporting Formwork was used to form generously-sized working and material platforms with the help of the PERI UP Scaffolding System. Each of 6.25 m long and 2.50 m wide load platforms fulfilled two tasks: the intermediate level under the right window was dimensioned for positioning a bulk materials container; large-sized materials could be moved out through the left window by means of a suspended Formwork Carriage. The customized PERI solution was geometrically adapted regarding the structural dimensions and statically with regard to platform usage requirements. Equally helpful for the planning and installation was the uniform 25-cm modular grid arrangement of VARIOKIT and PERI UP as well as the standardized connecting means. The exclusive use of rentable standard components resulted in considerable time savings and, in particular, numerous cost advantages.

The 5-star Hotel Le Royal in the centre of Luxembourg underwent extensive renovation work in 2015. For this, complete sections of the structure had to be gutted and totally renovated in the space of only 9 months whereby a total of 165 rooms were completely emptied and stripped down to the building shell. The safe and quick disposal of the rubble as well as removing

large-sized wall and slab panels was carried out by means of an offset arrangement of cantilevered load platforms on each floor. Due to the expansion construction work on the ground floor, erecting a working scaffolding on the facade side was not possible; furthermore, anchoring on the hotel frontage was also not permitted.

Hvězdonice Motorway Bridge, Czech Republic Flexibly adapted building safeguards from the modular construction kit

For temporary support of an unsound motorway bridge, the PERI solution was quickly available due to the use of VARIOKIT system components, and ensured reduced material and assembly costs as well as a reduction in cost expenditure. The D1 stretches eastwards from Prague via Brno and on to Poland. With a length of 375 km, it is the longest but also the oldest motorway in the Czech Republic. Construction was started 75 years ago and, accordingly, some sections are in urgent need of refurbishment. In order to safely maintain road traffic operations, a motorway bridge which had fallen into disrepair 30 km southeast of Prague had to

be temporarily supported up to the time of the planned new construction. The 90 m long structure was built in the 1970s using prefabricated components. With regard to the building safeguards, the concept developed by PERI´s Czech engineers provided 44 VST Heavy-Duty Shoring Towers using components from the VARIOKIT Engineering Construction Kit. The system allowed flexible geometrical and load adjustments to suit the predetermined points of support with tower heights up to 11.30 m. For transferring the increased load concentrations in the bridging area of the main road, the load-bearing capacities could be doubled by means of additional legs. The

fine adjustment of the head spindles and the activation of the support were carried out with the help of mobile hydraulic units while the pre-tensioning forces were continuously monitored. VARIOKIT saved on both costs and time due to the availability in the PERI rental park: the rental of standardized system components provided, on the one hand, a cost-effective structural solution and, on the other, the required materials could be quickly delivered to the jobsite. Further time-savings could be achieved through the easy and simple VST assembly procedure using standardized fitting pin connections. In addition, the construction team was supported by an experienced PERI supervisor.

Refurbishment of the Inntal Bridge A12, Radfeld/Tirol, Austria All clear: bridge renovation without any jobsite traffic jams

Building Redevelopment

Manfred Neuhauser Site Manager “At bauma 2013, we found the right system solution at PERI for our construction projects. Together with the PERI engineers, a project-specific concept was developed using the VARIOKIT parapet track and the mobile PERI UP suspended scaffold system. Thus, it was possible – and also thanks to the simple handling – to realize all operations in the given time without any problems.”

The VARIOKIT carriage for suspending the PERI UP suspended scaffold by means of DW 15 tie rods could be moved within the existing crash barriers.

The moveable units were attached via rollers and rails completely to the underside of the cantilever which meant the superstructure remained freely accessible.

The refurbishment of the 185 m long Inntal Bridge was carried out by two complementary PERI modular construction systems – to a large extent without restricting road traffic.

Contractor Strabag AG, Direktion AF Verkehrswegebau Tirol/Vorarlberg, Innsbruck Field Service PERI Nußdorf/Austria and PERI Weissenhorn/Germany

For the bridge renovation, a project-specific PERI system solution ensured smooth working operations. The flow of traffic remained largely unaffected and the construction schedule was easily maintained. The rentability of the components and their easy handling increased the cost-effectiveness. The A12 Inntal autobahn between Kufstein and Innsbruck is part of an important European road axis. During the renovation and widening work on the 185 m long, over 40 years old Inntal Bridge, road traffic on both carriageways should remain largely unaffected throughout. The formwork and scaffolding solution from PERI was based on two complementary modular construction systems: the VARIOKIT engineering construction kit and the PERI UP scaffolding system. Furthermore, two essential elements of the PERI overall solution were the planning service and supervisor´s position then the incomplete as-built documentation required high degree of flexibility and maximum adaptability – in the planning phase as

well as during assembly and use on site. For refurbishing the outer parapets on the north side, two VARIOKIT parapet tracks were used. These ran on rollers on the underside of the cantilever. As a result, the superstructure was free of any disruptions whereas the existing drainage system was removed in several stages along with demolishing the old parapet while the new parapet was then shuttered and concreted section by section as well as new drainage pipes were also being installed. In addition, the mobile platform served to store and transport the resulting construction rubble. For the underside renovation and replacement of the drainage system in the area of the internal cantilevers, movable PERI UP suspended scaffold was used. Suspension was carried out by means of DW 15 tie rods between the two superstructures, and suspended at the top on a carriage comprised of VARIOKIT system components – within the crash barriers and without requiring any time-consuming and expensive cordoning off measures.

Our commitment to environmental protection All relevant CO2 emissions which result from producing the PERI Handbook will be determined in accordance with the “natureOfffice procedure” and offset via the purchase and binding suspension of approved certificates of climate protection. In addition, the wood used for the paper production of the PERI Handbook comes from FSC®-certified forests. The FSC® label confirms that the entire processing and comercial chain – from the forest and wholesalers through to the printing stage – is fully certified.

Important notes All current safety regulations and guidelines must be observed in those countries where our products are used. The photos shown in this brochure feature construction sites in progress. For this reason, safety and anchor details in particular cannot always be considered as conclusive or final. These are subject to the risk assessment carried out by the contractor. In addition, computer graphics are used which are to be understood as system representations. For ensuring a better understanding, these and the detailed illustrations shown have been partially reduced to certain aspects. The safety installations which have possibly not been shown in these detailed descriptions must nevertheless be available. The systems or items shown might not be available in every country. Safety instructions and load specifications are to be strictly observed at all times. Separate structural calculations are required for any deviations from the standard design data.
