Singapore Changi Airport Terminal 4 is an upcoming passenger terminal building at Changi Airport. The construction of the new Terminal 4, commenced on November 2013. Under a new concept of Fast And Seamless Travel at Changi (FAST@Changi) it will see options such as self-service check-in, self-bag tagging, automated baggage drop, immigration clearance and departure gates being rolled out extensively in the new building. The new Terminal 4 will be a two-storey, 25-metre-high building with a gross floor area of 195,000 square metres (seven times larger than the previous Budget Terminal). 17 stands will be available for narrow body aircraft, 4 stands for wide body planes. A bridge across Airport Boulevard will be constructed to enable buses and other airside vehicles to move from T4 to distant aircraft stands. There will also be a new dedicated 68-metre-high Ramp Control Tower constructed. While great emphasis has been placed on high technology within the new terminal space, it will be connected to the Terminal 2 by a conventional Airport Shuttle Bus rather than the automated Changi Airport Skytrain that links the other terminals.
