Singapore International Airport at Paya Lebar, Singapore's third main civilian airport after Seletar Airport (main airport from 1930–37) and Kallang Airport (1937–55) opened in 1955 with a single runway and a small passenger terminal. With growth in global aviation transport, the airport was facing congestion problems. Its inability to cope with the rising traffic became critical by the 1970s; annual passenger numbers rose dramatically from 300,000 in 1955 to 1,700,000 in 1970 and to 4,000,000 in 1975.
The government had two options: expand the existing airport at Paya Lebar or build a new airport at another location. After extensive study, a decision was made in 1972 to keep the airport at Paya Lebar, as recommended by a British aviation consultant. Plans were made for the building of a second runway and an extensive redevelopment and expansion to the passenger terminal building. A year later, however, the plans were reviewed again as the pressure to expand the airport eased because of the 1973 oil crisis.
Concerned that the existing airport was located in an area with potential for urban growth, which would physically hem it in on all sides, the government subsequently decided in 1975 to build a new airport at the eastern tip of the main island at Changi, at the existing site of Changi Air Base, where the new airport would be easily expandable through land reclamation. However, as there was an increase in traffic, the airport still had to be expanded at that time. In addition, airplanes could fly over the sea, avoiding noise pollution issues within residential areas like those at Paya Lebar and helping to avoid disastrous consequences on the ground in the event of an air mishap. The airport in Paya Lebar was subsequently converted for military use as the Paya Lebar Air Base.

The airport was one of the largest single development projects in Singapore's history. Led by PSA chairman Howe Yoon Chong, land-reclamation works involving over 52,000,000 square metres (559,700,000 sq ft) of landfill and seafill began in June 1975, even as the airport at Paya Lebar was still in the midst of expansion works. About 2 km2 (0.77 sq mi) of swamp land was cleared and filled with 12,000,000 m2 (129,200,000 sq ft) of earth from the nearby hills, while another 40,000,000 m2 (430,600,000 sq ft) of sand from the seabed were used to reclaim land. The contractor was PentaOcean Construction (五洋建設), a Japanese construction firm directly involved in numerous land reclamation projects in Singapore. Canals were built to drain water from three rivers, Sungei Tanah Merah Besar, Sungei Ayer Gemuroh and Sungei Mata Ikan. In total, 8.7 km2 (3.4 sq mi) were reclaimed, raising the total site area to 13 km2 (5.0 sq mi). Of this, landfill accounted for 2 km2 (0.77 sq mi) while seafill represented 6.7 km2 (2.6 sq mi). The construction also demolished 558 buildings, exhuming around 4,100 graves, a 38.1 centimetres (15 in) gun emplacement at Changi, and diverting the three streams to the western side of the former Royal Air Force runway, which was to be used for the new 4,000 metres (13,123 ft) runway. All of these works were completed in May 1977. From 1977 to 1979, it was used to pile-drive the foundation of Terminal 1 and other buildings as well. The foundation stone for Terminal 1 was laid in August 1979. The 78 m (256 ft) high control tower is built on reclaimed land, with its design becoming an icon for the airport. The original name of the control tower was "Airtropolis", but was seldom used. The column-free hangar with an area almost as large as the Padang could hold three Boeing 747s. Its roof was constructed in Batam, and was shipped to Singapore in four separate sections by barge. A special jetty was built on the coast to obtain fuel from the Western Islands by shipping it round the coast. The fuel is pumped for a mile to the airport fuel station run by six oil companies on the north-eastern perimeter. The pipelines then leads to all the parking bays through a pipe some 5 m (16 ft) below ground level.[11]
The first phase costing about S$1.3 billion opened on 1 July 1981 with the first flight, Singapore Airlines Flight 101, touching down at 0700 hours Zulu with 140 passengers from Kuala Lumpur.[12] Officially opened with much fanfare five months later on 29 December 1981 by Howe Yoon Chong, the airport had 34 airlines operating 1,200 scheduled flights each week connecting Singapore to 67 cities in 43 countries. It ended its first year operations with 8.1 million passengers, 193,000 tonnes of air freight handled and 63,100 aircraft movements.[13]
Despite the airport opening in 1981, some sections were not completed. The big aircraft hangar was only completed in 1982, and the first runway was completed only in 1983. This was the year in which the now defunct government department, the Public Works Department decided to focus on the construction of the second runway on the reclaimed land east of the Terminal 1. The sections of phase 2 opened progressively over the next few years with the completion of a second runway as well as other facilities. In 1985, the construction work on Terminal 2 started, south of Terminal 1. Terminal 2 was completed in 1989, and was opened in November 1990 with its official opening on 1 June 1991 by Prime Minister Goh Chok Tong. The opening of the second terminal was way ahead of passenger demand.[11]
