Istanbul Airport is the world’s largest airport terminal under a single roof, spanning 1.4 million square meters of terminal space across a 76.5 million square meter campus. Built by the Cengiz-Kolin-Limak-Mapa-Kalyon consortium and designed by Grimshaw Architects, Nordic Office of Architecture, and Haptic Architects, the project demanded construction solutions that could deliver speed, scale, and structural efficiency simultaneously. Disposable void formwork was applied in [doğrulanacak: raised floor areas / terminal foundation fills / landscape areas / car park structures], providing lightweight fill that reduced dead load on the foundation while accelerating the construction schedule. With 90 million annual passenger capacity in Phase 1 alone, the project illustrates how void formwork technology performs at megaproject scale — the same system TurStructure supplies and supports on site for airport, infrastructure, and large-scale commercial projects.
