Changi Airport Group (CAG) has awarded contracts for substructure and airside infrastructure works at Changi Airport’s Terminal 5 (T5), valued at about $2.9 billion (S$3.8 billion) and $730 million (S$950 million), respectively.
The substructure contract has been awarded to a joint venture between the Singapore branch of China Communications Construction Company (CCCC) and Obayashi Singapore Pte Ltd. 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 140 hectares with a basement depth of up to 28 meters, equivalent to about 5,200 Olympic-sized swimming pools put together.
A separate contract has also been awarded to Hwa Seng Builder Pte Ltd. for airside infrastructure works. The works include the development of remote aircraft stands, connecting taxi lanes and ancillary support buildings.
Ong Chee Chiau, CAG’s Managing Director, Changi East said: “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.”
