Changi Airport Group (CAG) has awarded contracts for the substructure and airside infrastructure works at Changi Airport’s Terminal 5 (T5). These contracts are valued at about S$3.8bn (US$2.9bn) and S$950m (US$736m), respectively.
Substructure and airside infrastructure contracts
The substructure contract has been awarded to a joint venture between China Communications Construction Company (Singapore Branch) (CCCC) and Obayashi Singapore. It comprises the construction of the foundation and basements of the T5 main passenger terminal and ground transportation center, as well as a portion of the tunnels linking T5 and Terminal 2 (T2). The substructure site covers about 140ha with a basement depth of up to 28m.
A separate contract has also been awarded to Hwa Seng Builder for airside infrastructure works, including the development of remote aircraft stands, connecting taxi lanes and ancillary support buildings.
Changi East development plans
T5 is part of the larger Changi East development that includes Changi Airport’s third runway, as well as cargo complexes and other supporting aviation and ground transportation infrastructure. The construction of T5 will start in the first half of 2025 and is expected to be completed in the mid-2030s.
Ong Chee Chiau, CAG’s managing director for Changi East, said, “The appointments of the contractors for substructure construction and airfield works bring us closer to the start of T5’s construction. With a planned capacity of 50 million passengers annually, T5 represents one of the most complex construction projects in Singapore. Both CCCC and Obayashi Singapore bring a wealth of experience in civil engineering, construction and project management, with a strong track record in delivering large-scale infrastructure projects both in Singapore and internationally.
“Hwa Seng Builder brings valuable local expertise and deep familiarity with Changi Airport, built through the successful delivery of various past projects. Together with our partners, we will ensure that the high standards which define Changi Airport can be replicated or even surpassed in the development works of T5.”
