Changi Airport Group awards $999m contract for T5 tunnel system
The Straits Times
|June 11, 2025
A contract worth $999 million for the construction of underground tunnels at Changi Airport's Terminal 5 (T5) has been awarded to a joint venture between a Japanese construction company and a Singapore-based construction and civil engineering firm.
Construction of the tunnel system, which will transport passengers and baggage across T5, is expected to take more than four years, Changi Airport Group (CAG) said on June 10, about a month after a ground-breaking ceremony for the terminal.
It will be built by Penta-Ocean Construction and Koh Brothers Building and Civil Engineering Contractor (KBCE).
The tunnel system will house key infrastructure, including automated people-mover systems similar to the Skytrain, as well as baggage-handling systems. There will be two people-mover systems within T5 that can connect departing passengers to their gates and arriving passengers to two arrival immigration halls.
A common services tunnel will contain dry and wet utilities such as electrical power, communication systems and water services.
CAG said the works also include a ventilation building that will support this tunnel, and provisions for a future underground infrastructure tunnel.
