A new air traffic control (ATC) tower, worth Rs3.5bn ($51.6m), will be built at Indira Gandhi International Airport (IGI) in Delhi, India.
The 22-storeyed new ATC will be one of the tallest structures in Delhi, built at a height of 101.9m.
The ATC's visual control room will have 21 controller positions while 12 ground controller positions will be at operational level.
The administrative block, meant for Airport Authority of India officials, will feature an area control centre and an approach control centre besides traffic flow management system.
The tower will enable a 360-degree view of the airport, including the three runways, apron area and taxiway, reported The Times of India.
Once the new tower opens, the old control tower will stay operational for at least six months.
The tower is expected to open by around May-June this year.
Although construction of the tower began in early 2012, it has already missed three deadlines, primarily due to VIP movement.
Sources told the publication that the tower will also be used as a training centre for newly appointed staff.
The new ATC tower is being constructed next to the existing structure. The new tower will feature a 50-tonne tuned mass damper, which can stop additional sway during critical winds and give stability to the structure.
"Such equipment has not been installed at any airport in the country before. The damper will move in the opposite direction to which the building is moving, thereby producing a counter-balancing and stabilising force," an airport official was quoted by the publication as saying.
Further, the tower can withstand zone-5 seismic forces.
Earlier this month, the airport stepped up its security following a 'non-specific call' to its control room about an impending bomb blast at the airport.
