Exploring Singapore Changi Airport's Massive Scale And Complexity

Singapore Changi Airport is Singapore's main international airport and a major aviation hub in the Asia-Pacific region. The airport is located approximately 25 km (16 mi) east-northeast of the city's commercial centre, on a 2,400-hectare (5,900-acre) site on the easternmost point of Singapore Island. Changi Airport initially opened in 1981 and has since grown with the rising number of passengers. The airport is currently undergoing a significant expansion, with the addition of Terminal 5, which is expected to double its size and increase its annual passenger handling capacity to accommodate future growth in air travel.

Terminals and runways

Singapore Changi Airport currently has four terminals (T1, T2, T3, and T4) and two runways. The terminals are connected via a people mover system, with airside passengers being able to move between T1, T2, and T3 without passing through immigration. Transport within and between these three terminals is also provided by people movers and the skytrain system, and it is possible to walk between them on foot. T1 is built in an H-shape to maximize gate space and is home to a Tropical Rainforest Vivarium, the Water Lily Garden, and the Kinetic Rain Sculpture. T2 is larger than T1 and is home to several Star Alliance carriers, including Air India, Lufthansa, and United Airlines. T3 is linked to the Crowne Plaza Changi Airport hotel, which has 563 rooms.

Changi Airport's largest expansion project to date, the Changi East development, will provide future capacity for the airport. It will include a new terminal (T5), a three-runway system, and the Changi East Industrial Zone. The existing third runway, previously used only by the military, has been extended from 2.75 km to 4 km to handle larger passenger aircraft.

Masterplan and construction

The Singapore Changi Airport, formerly known as the Singapore International Airport, was constructed at the tip of the main island at Changi. Given the limited land resources in Singapore, the airport was built on reclaimed land on the eastern part of the island. This allowed for future expansion without using valuable land in Singapore and minimised noise pollution as aircraft approach over the sea. The airport is operated by the Changi Airport Group, a wholly-owned subsidiary under the purview of the Ministry of Finance of the Government of Singapore.

The original master plan for Changi Airport involved a dual-terminal and dual-runway configuration over two phases, with provisions for two additional passenger terminals in the future. The first phase of construction included the first runway, 45 aircraft parking bays, a fire station, and a cargo agent building. The airport commenced commercial operations on 1 July 1981, with its first flight, Singapore Airlines SQ101, arriving from Kuala Lumpur with 140 passengers.

The second phase of construction included the second runway, 23 additional aircraft parking bays, a second fire station, and a third cargo agent building. Terminal 2 (T2) opened in 1991, and Terminal 4 replaced the former budget terminal in 2017. Changi Airport's iconic control tower was constructed in 1980, and the airport MRT station opened in 2002.

Currently, the airport is undergoing its biggest expansion to date with the construction of Terminal 5 (T5) and the implementation of a three-runway system. The Changi East development project will span 1,080 hectares and is expected to be completed by 2030. The project will include the construction of tunnels and other underground systems, landside and aviation support, and the Changi East Industrial Zone. The Singapore government and the Changi Airport Group have committed significant investments to this project, ensuring the airport's competitiveness and ability to handle growing passenger traffic.
