Singapore’s ambitious expansion of Changi Airport is moving full steam ahead with the awarding of two major construction contracts worth a combined S$4.8 billion (approximately $3.7 billion). The development centers around Terminal 5 (T5), set to become the largest terminal at Changi, designed to accommodate 50 million passengers annually.
A joint venture between China Communications Construction Co. and the Singapore arm of Obayashi Corp. secured the S$3.8 billion contract for the substructure works, while Hwa Seng Builder won the S$950 million airside infrastructure contract. Construction is scheduled to begin in the first half of 2025, with completion expected in the mid-2030s.
T5 forms part of the wider Changi East development, which also includes a third runway, cargo facilities, and expanded ground transport systems. The substructure project will span 140 hectares, with basements reaching depths of up to 28 meters—equivalent to 5,200 Olympic-sized swimming pools.
Airside works will involve the creation of aircraft stands, taxi lanes, and auxiliary buildings, critical for supporting the future growth of Changi’s operations.
Changi Airport recently reclaimed the title of the world’s best airport at the Skytrax World Airport Awards, strengthening its global reputation as a premier aviation hub.
