The formwork carriage has been designed so that trucks can pass through at any time without obstacles. Due to the cramped site conditions, an absolutely essential requirement for the execution.
For construction of the emergency parking bays, the formwork carriage was designed with a width of 14.30 m. Moving the carriage to the next bay through the smaller-sized standard cross-section, required a reduction in the maximum external dimensions.
Two steel arches, each with a span of 148 m, carry the middle section of the Waldschloesschen Bridge 26 m above the Elbe.
Simple connecting means and the compatibility of the VARIOKIT Engineering Construction Kit with the PERI UP Modular Scaffolding have facilitated safe access and working platforms in all areas.
Thanks to the detailed planning provided by PERI engineers and high flexibility of the PERI balanced cantilever equipment, the superstructure of the cable stay bridge could be completed according to the schedule.
The 258 m long and 50 m high arched bridge crosses the Opamo Valley in the Bohemian Forest.
Up to 30 m high VARIOKIT VST heavy-duty shoring towers served as falsework for the construction of the bridge edge sections. Each leg carried a load of around 600 kN.
Using a combination of ACS self climbing technology and the VARIO GT 24 girder wall formwork, a solution was developed which was crane-independent as well as ensuring maximum safety in all types of weather.
The VARIOKIT formwork carriage ensured rapid concreting sequences for the construction of the new subway station in Seattle. HD 200 heavy-duty props served as temporary support for the longitudinal edge beams.
The 22.25 m wide superstructure sections were constructed with section lengths ranging from 3.40 m to 4.10 m in regular 10-day cycles.
The 3rd Bosphorus Bridge has the highest concrete bridge piers in the world, and will eventually connect the European and Asian continents after its completion in 2015.
Only when seen from an aerial perspective is the scale of the construction site really apparent: the area is the size of around 2,000 football pitches.
The 180 m long tunnel elements are cast in eight individual segments each 22.50 m long – monolithic, without ties and in compliance with strict dimensional tolerances.
In the complex area with an extremely tight outer radius, the concentrated loads of the radially-arranged cantilever brackets are transferred into the available bridge piers by means of pressure supports.
The Lekki Ikoyi Bridge in Lagos is the first cable-stay bridge in Nigeria.
The VARIOKIT tunnel formwork solution accelerated construction of the 228 m long Marchlehner gallery situated at a height of 1,800 m above sea level. The competent planning process took into account al possible project requirements which ensured on-schedule completion before the onset of winter.
The Midfield Terminal Complex is the ultimate in construction sites: in order to maintain the tight construction schedule, PERI planned and delivered the formwork and scaffolding systems, and has provided yet another convincing performance through the competent engineering service and provision of huge quantities of materials at short notice.
The Algerian metro station "Place des Martyrs" is 144 m long and features record-breaking dimensions with its 23 m width and 14.80 m height.
A VARIOKIT cantilevered parapet carriage serves for constructing the external cantilevered parapets. The horizontal loads are transferred via friction, anchoring is not required.
With some supplementary system components, the VARIOKIT engineering construction kit can also be used for the balanced cantilever construction method. For the construction of the motorway bridge near Tarnow, the construction crew achieved a 4 to 5-day cycle thanks to the easy to use, mechanical solution. At the same time, the high requirements concerning the very small tolerances for the variable bridge cross-sections could be fulfilled.
Designed by Zaha Hadid, the new station – a construction consisting of concrete, glass and steel in the form of a bridge – is characterized by numerous curved shapes. Traffic flows from travelers inspired the architect to create this extraordinary shape.

PERI supplied a project-specific formwork and scaffolding solution and supported with comprehensive engineering services for the construction of the 108-m-high complex dam on the River Tua in Portugal.
The Smithland hydroelectric power plant is equipped with 3 turbines; due to the extremely tight construction schedule, all three tubes with their constantly changing cross-sections are being realized at the same time.

The LGS Weather Protection Roof on the basis of the PERI UP Scaffolding System made the roof renovation independent of the weather. The 90 m long protection roof consisted of 3 m wide and nearly 30 m long LGS segments.
The first of a total of three sections will become operational in the autumn of 2017.
Through the planning and supply of formwork and scaffolding from one source, the MULTIFLEX slab formwork and PERI UP shoring could be perfectly matched.
The VARIOKIT heavy-duty shoring towers with a height of 23.60 m can support loads of over 200 t in each case. The horizontal assembly of the approx. 10 m high tower sections makes the erection of the shoring easy and safe.
Cost-effective PERI climbing concept: with a complete platform level and halved on-site wall formwork requirements, fast and continuous working operations were achieved.
The two-storey supporting structure, with a height of 25 metres, accommodates the sorption installation for the flue gas desulphurisation.
Only 7 months after beginning the excavation and foundation work, the topping-out ceremony took place; 8 months later, production started in August 2009.
A total of 9 circular piers with 3.60 m diameters and 40 cm wall thicknesses will subsequently carry a steel platform for the condenser.
A unique suspended slab-support system was designed for this project.  A travelling gantry was designed to meet the unique time and labour requirements for this project.
