Terminal 4, Changi International Airport

A new terminal, designated as Terminal 4 (T4), is being constructed at Changi International Airport of Singapore.

The Terminal 4 project was initiated in February 2013. The construction started in November 2013 and is expected to be completed by 2017.

Changi airport, operated by the Changi Airport Group (CAG), is Asia’s sixth busiest international airport. It handled more than 51.2 million passengers in 2012. The new T4 is expected to handle about 16 million passengers per year and will increase Changi Airport’s annual passenger handling capacity to 82 million by 2017.

The total cost of the T4 project is estimated at S$1.28bn ($1.03bn), including S$600m for the terminal construction and S$680m for the airfield infrastructure construction.

Changi airport Terminal 4 design and construction

"The construction started in November 2013 and is expected to be completed by 2017."

The T4 will be constructed on the site of the old Budget Terminal located about two kilometres away from the three main terminals. The Budget Terminal was opened in March 2006 and closed in September 2012. It was demolished in 2013 to construct the new T4.

Terminal 4 will be a two-storey building with a gross floor area of about 195,000m². The terminal design is inspired from an orchid petal. The terminal building will be 25m high featuring 25 aerobridge gates.

A separate Ramp Control Tower will be built to monitor the aircraft movements in the apron and taxiways around the terminal. The 68m tall tower will provide clearance to pilots.

The terminal will feature a 300m long Central Galleria, which will be a glazed open space that visually connects the departure, check-in, arrival and transit areas across the terminal.

A new overhead vehicular bridge will be built across the airport boulevard to connect the T4 and the aircraft stands.

It will also enable the movement of buses and other airside vehicles.

Passenger facilities at Changi airport’s new terminal

The new terminal will feature kiosks for self check-in, self bag-tagging and self bag-drops. It will also feature an advanced and automated baggage handling system.

"Changi airport, operated by the Changi Airport Group (CAG), is Asia’s sixth busiest international airport."

Self-service and automated options will be offered at check-in, bag drop, immigration counter and departure-gate boarding.

Biometric technology and fast and seamless travel (FAST) services will be implemented at the terminal to reduce manpower and increase efficiency.

The T4 will feature 15,000m² of shopping, dining, liquor, tobacco, perfumes, cosmetics and other retail spaces. It will implement a new walk-through retail concept. It will also feature local, cultural and heritage-theme restaurants, as well as retail stores.

Changi Terminal 4 parking and transport infrastructure

Two new car parks will be constructed at the terminal, to accommodate up to 1,500 vehicles. The terminal will be internally connected to the new car parks via sheltered links. One of them will be a multistorey car park located next to the terminal. Another will be an open air car park constructed in front of the terminal.

A 38ha plot at Terminal 3, which houses the airport nursery and a reservoir, will be converted into an aircraft parking area. The aircraft parking area will be able to store up to 17 narrow-body and nine wide-body aircraft stands.

A new road will be constructed connected to the East Coast Parkway to manage the outgoing traffic from T4.

A free airside shuttle between terminal 4 and terminal 2 will be constructed to facilitate the non-T4 airlines passengers. T4 will also feature a centralised departure bus lounge, with up to nine bus bays providing quick transportation services to the passengers.

Contractors involved with the Terminal 4 project

A consortium led by SAA Architects was selected by CAG to design and construct the T4 in April 2013.

The consortium also includes Benoy, AECOM Singapore and Beca Carter Hollings & Ferner (SEA).

CSC Holdings will provide foundation works for the construction of the airport terminal building, ancillary buildings and other infrastructure under a contract awarded in September 2013.
