The new Integrated Terminal Building at Mumbai’s Chhatrapati Shivaji International Airport combines international and domestic operations at one of the busiest airports in India. The 410,000-square-meter building, being constructed at the site of the existing terminal, will achieve a capacity of 40 million passengers per year upon completion in 2014.

The primary design feature of the building is a long-span roof covering a total of 70,000 square meters over various functional requirements, making it one of the largest roofs in the world without an expansion joint. The Headhouse Roof, supported by only 30 columns spaced at 64 meters in the north–south direction and at 34 meters in the east–west direction, produces a large column-free space ideal for an airport. By increasing the depth of the trusses near the columns and running trusses in both an orthogonal grid and a 45-degree grid, large spacing and cantilevers of 40 meters along the perimeter are achieved with an overall truss depth of only four meters.

In response to the site constraints and proximity of the existing operational terminal building, the mega-columns are also designed to serve as hoist mechanisms, enabling the entire roof to be constructed without tower cranes. The Terminal Building also includes the largest and longest cable wall system in the world. The structural studies completed include solid finite element analysis of connections to optimize material efficiency. Furthermore, the structural design prioritizes modular construction for economy and facilitation of an accelerated construction schedule.
