Singapore's Changi airport has unveiled plans for its fourth terminal, which it says will help to increase capacity by almost 25% when it is operational by 2017.
Terminal 4, which will have a planned capacity of 16 million a year, will cater to both full service and low-cost carriers. The two-storey 160,000m² (1.72 million ft²) building will be at the site of the airport's old budget terminal, says operator Changi Airport Group (CAG).
It will be designed primarily to handle narrowbody aircraft. The airside transfer of passengers and baggage to Changi's other terminals will also be possible. Construction is scheduled to begin this year and the entire development is expected to cost S$600 million, says Changi.
The airport is also looking to expand the capacity of its existing Terminal 1 by another 3 million. Together with Terminal 4, this will give Changi an annual passenger handling capacity of 82 million.
In addition, the airport also plans to increase the number of aircraft parking stands. It will convert a 38ha (94 acres) land plot south of the existing Terminal 3 into an aircraft parking area that can house 17 narrowbody and nine widebody aircraft.
This S$680 million project will increase the total number of aircraft stands at Changi - including the new ones at Terminal 4 - by 24% to 180.
Both the CAG and the Civil Aviation Authority of Singapore (CAAS) have been looking into measures to improve airport and runway capacity over the last few years. The CAAS is expected to announce soon that an existing military runway beside the airport will eventually be converted for civilian use.
