The airport's operator said on May 5 that the substructure includes the foundation and basements of the main passenger terminal.

Changi Airport Group (CAG) said the substructure contract, valued at about $3.8 billion, was awarded to a joint venture between the Singapore branch of China Communications Construction Company (CCCC) and Obayashi Singapore, a subsidiary of Obayashi Corporation, one of Japan's biggest general contractors.

The joint venture will be responsible for building the foundation and basements of the main passenger terminal and ground transport centre, and a portion of the tunnels linking T5 and the existing Terminal 2.

Covering about 140ha with a basement depth of up to 28m, the substructure site is equivalent to about 5,200 Olympic-size swimming pools.
