Indira Gandhi International Airport Air Traffic Control Tower

At 335 feet high, the new air traffic control tower (ATC) at Indira Gandhi International Airport (IGIA) is one of the world’s tallest.

The ATC’s tall, slender architectural form complements the structural system, which includes tuned mass dampers near the top of the tower that reduce mechanical vibrations under wind loads.

Its central location provides 21 controllers with 360-degree views of the airport’s runways, aprons and taxiways. On the operations level are 12 ground control stations.

HOK collaborated on the project with BurroHappold Engineering.
