Peri rises to challenge at Istanbul airport

01 December 2019

Formwork systems from Peri were deployed to build the gigantic main terminal building of the new airport in Istanbul, Turkey, which opened just over a year ago.

The airport is located north-west of Istanbul and features six runways and, in 10 years’ time, is expected to handle a larger passenger volume than that currently handled by the world´s largest airport in Atlanta, US. Istanbul Airport can accommodate around 90 million passengers per year but can easily be expanded to handle up to 200 million passengers annually.

Various Peri systems were used not only for erecting the main terminal building but also for constructing various other facilities. These systems were used by a total of 13 different building contractors involved in the construction of the airport. A range of Peri systems was used to construct, for example, a multi-storey car-park, maintenance building, fire station, cargo building, energy building, wastewater treatment plant, subway terminal, passenger and luggage tunnels, security building and a mosque.

Using state-of-the-art Peri formwork technology, the construction team successfully formed the high walls and columns of the terminal in the best architectural concrete quality.

Elaborating on the use of the formwork, a spokesman for Peri says: “Walls and slabs up to 14 m high with a thickness of up to 1.75 m were constructed in one part of the building. In the process, the slab beams featured heights of up to 2.30 m. The construction team formed the reinforced concrete core walls with Trio wall formwork because of the system’s numerous advantages.

“One particular advantage of using Trio is the possibility of moving large-sized units by crane. This also saved valuable time during the project’s construction phase. The minimum of different components and the universally applicable BFD Alignment Coupler, likewise, accelerated and simplified forming operations with the proven panel formwork.”

High productivity

For processing the approximately 220,000-sq-m slab area at a height of 17.50 m, the construction teams installed a total of 15,500 sq m of platforms with spans of up to 15 m and supported by Peri Up Flex shoring. In order to fulfil all the requirements of the clients, the Peri Up scaffolding completely shielded site activities from ongoing airport operations. The scaffolding construction simultaneously served as working scaffold. Installation of system decking provided protection for the area under the platforms so that the check-in desks could be installed beforehand.

“Due to the tight schedule and the enormous slab area, it was also necessary to minimise both the assembly and moving times for the working platforms,” the spokesman continues. “As a result, Peri used transportation wheels in order to easily move the platform elements by hand in a longitudinal direction. Thanks to the high degree of system rigidity, an area of up to 540 sq m could be moved as one unit. Independent of the height of the platforms – some of the working platforms were mounted at heights of up to 40 m – the LGS elements could be manually moved to their next place of use in only 15 minutes.”

Peri worked closely together with all participants to ensure that the large quantities of materials were delivered on a just-in-time basis in spite of the short lead time.

“Right from the very beginning, Peri engineers and supervisors provided extremely reliable support through comprehensive on-site assistance in order to ensure that all system devices were efficiently used from the outset. Thanks to the close cooperation between Peri Turkey and Peri GmbH along with the help of the state-of-the-art system solutions, it was possible to successfully realise this extremely important project and in the shortest possible time,” the spokesman concludes.
