The Indira Gandhi International Airport (IGI) in India will receive the tallest air traffic control tower (ATC) in the country by 2013.
The Airports Authority of India is finalising the design of the tower, which will measure 90-95m and cost between INR700m ($15m) and INR800m ($17m), according to The Times of India.
The entire project, including automation and installation of the tower, will cost the Airports Authority of India (AAI) nearly INR2,500m ($53m) to INR3,000m ($64m).
Designed by Hong Kong-based architects HOK International, the tower features a central lift and will be built between the existing tower and Terminal 3 to provide a better view to air traffic controllers.
The ATC will be equipped with a flow management system linked to a central control system to give controllers a clear picture of the congestion situation at the airport.
Construction of the tower is expected to begin soon.
