- A centrally located airport in India.
- Conducting wind tunnel testing of the air traffic control tower to mitigate against monsoon winds.
The new Rajiv Gandhi International Airport is located approximately 22km south west of Hyderabad City, one of the fastest growing cities and the sixth largest metropolitan area in India. With its central location in India, the airport will serve as a hub for domestic passengers, international passengers and cargo traffic.
The passenger terminal building comprises a five-level reinforced concrete frame supported on pad foundations, covered with a structural steelwork roof with spans up to 45m in length. A lightweight fabric roof structure covers the pick-up and drop-off areas along the frontage access to the airport. The design has provided flexibility to enable future expansion that will ultimately cater for a capacity of over 40m passengers annually.
The 70m high air traffic control tower comprises a reinforced concrete slip-formed core with a steelwork cabin structure to the upper five levels of the tower to support air traffic and apron control areas. The Arup team undertook extensive wind tunnel testing of the tower, which resulted in the proposed perforated cladding and strake features to mitigate lateral accelerations induced by monsoon winds. The foundation for the tower is a raft foundation and the upper steelwork cabin structure includes a column-free perimeter to allow uninterrupted views over the airfield.
