Changi Airport awards S$999 million contract for T5 intra-terminal tunnels
Construction will be undertaken by a joint venture between Japanese firm Penta-Ocean Construction and a subsidiary of Koh Brothers Eco Engineering
[SINGAPORE] Changi Airport Group (CAG) has awarded a S$999 million contract for the construction of intra-terminal tunnels at the upcoming Terminal 5 (T5).
The contract was bagged by a joint venture between Japanese firm Penta-Ocean Construction and a subsidiary of Koh Brothers Eco Engineering, a local construction and engineering company.
The intra-terminal tunnels will serve as underground connections within T5, said CAG in a Tuesday (Jun 10) press statement. These will support the transfer of passengers and baggage across the terminal’s concourses while facilitating the routing of common utilities.
The project, expected to take more than four years to be completed, will also comprise a ventilation building and provisions for a future underground infrastructure tunnel.
The announcement follows the groundbreaking of T5 in May.
When the mega terminal opens in the mid-2030s, it will consolidate the operations of Singapore Airlines and Scoot, which are now spread across three terminals.

CAG estimates that with T5’s completion, Changi Airport’s annual capacity will grow to 140 million passengers, from the current 90 million – taking it into the ranks of Asia’s “mega airports”, defined as those that handle more than 100 million passengers a year.
The airport’s network is also projected to increase from around 170 city links to more than 200 by the mid-2030s.
At the terminal’s groundbreaking ceremony last month, CAG chief executive officer Yam Kum Weng noted that T5 will effectively double the size of Changi Airport. “It will give us the capacity to grow as an air hub of the region over many decades to come.”
Prime Minister Lawrence Wong, who is also finance minister, added that the mega terminal will bring more job opportunities for Singaporean companies and workers, particularly in the areas of data science, robotics and sustainability.
Its opening will also boost demand for services and workers, both in the airport and other industries, added PM Wong.
