Changi Airport Terminal 5 contracts worth S$4.75 billion awarded

Changi Airport Group (CAG) announced on Monday (May 5) that contracts of around S$4.75 billion in value for substructure and airside infrastructure works at Changi Airport’s Terminal 5 (T5) were awarded to various construction companies.

The substructure contract valued at S$3.8 billion was awarded as a joint venture (JV) between the Singapore branch of China Communications Construction Company (CCCC) and Obayashi Singapore.

The JV will involve the construction of the foundation and basements of the T5 main passenger terminal and ground transportation centre, 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 m – equivalent to about 5,200 Olympic-sized swimming pools.

Previously, CCCC developed two aircraft taxiways connecting runways two and three of Changi Airport’s three-runway system as the main contractor, as well as two underground tunnel sections for vehicular traffic underneath the taxiways.

As for Obayashi Singapore, it has undertaken major construction projects in Singapore since 1965. These include the 20-year East Coast reclamation project, the Changi Airport air traffic control tower and Jewel Changi Airport. Most recently, it completed the inter-terminal tunnels linking T2 and T5 for the automated people mover and baggage-handling systems.

A separate contract of S$950 million was awarded to Hwa Seng Builder for airside infrastructure works. These include the development of remote aircraft stands, connecting taxi lanes and ancillary support buildings.

Ong Chee Chiau, CAG’s managing director for Changi East, said: “With a planned capacity of about 50 million passengers annually, T5 represents one of the most complex construction projects in Singapore. 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.”

The construction of T5 will start in the first half of 2025, and is expected to be completed in the mid-2030s.
