Peri Systems in Use for Construction of a New Airport in Istanbul
Istanbul Airport can currently accommodate around 90 million passengers per year. When all phases are completed, in 2028, it will handle up to 200 million passengers annually. Two gigantic terminal buildings have been planned to deal with this enormous increase in passenger volume – the first terminal alone provides 1.44 million m2 of effective area.
A total of 13 different building contractors contributed to the completion using PERI systems, including İGA Havalimanları İnşaatı Adi Ortaklığı Ticari İşletmesi, of Istanbul.
Various PERI systems were used in the construction of the terminal building as well as for realizing other structures.
PERI systems were not only used in the realization of the main terminal building but also deployed for constructing various other facilities. A range of PERI systems were 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 in the best architectural concrete quality. In one part of the building, walls and slabs up to 14 m high with a width of up to 1.75 m were realized. In the process, the slab beams featured heights of up to 2.3 m.
The construction team formed the reinforced concrete core walls with TRIO wall formwork which offers the possibility of moving large-sized units by crane. This saved valuable working time during the Istanbul Airport project.
For processing the approximately 220,000 m2 slab area at a height of 17.5 m, the construction teams installed a total of 15,500 m2 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 minimize both the assembly and moving times for the working platforms. To that effect, 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 m2 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.
Last but not least, 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 realize this extremely important project and in the shortest possible time.
