Istanbul Finance Center (IFM) is Türkiye’s flagship financial district — a 3.3 million m² mega development built across 65.7 hectares in the Ataşehir district to position Istanbul alongside London, New York, and Dubai as a global financial hub. The complex houses the Central Bank of the Republic of Türkiye headquarters (a 354-meter, 62-storey supertall tower), major state bank headquarters, 1.4 million m² of office space, a 100,000 m² shopping center, a five-star hotel, and parking for 26,000 vehicles. A project of this scale generates vast areas requiring lightweight structural fill — podium levels connecting towers, landscaped plazas, car park ramp transitions, and raised floors above below-grade service infrastructure. Disposable void formwork was applied across multiple zones to create reinforced concrete raised surfaces without adding unnecessary dead load to the podium and foundation structures. In a complex where dozens of towers share interconnected below-grade parking and service levels, minimizing imposed loads on transfer slabs is a critical structural requirement. This project demonstrates how void formwork technology integrates into financial-district-scale developments — the same systems TurStructure supplies and supports on site for large-scale commercial and mixed-use projects.
