Changi Airport Group (CAG) has awarded to the joint-venture Penta-Ocean Construction Co Ltd (70%, Tokyo). and Koh Brothers Building & Civil Engineering Contractor Ltd (30%, Singapore) the EUR 675 million (SGD 999 million) contract for the construction of intra-terminal tunnels at Terminal 5 (T5). The groundbreaking of Terminal 5 (T5) was last 14 may: construction is expected to take more than four years.
The intra-terminal tunnels will serve as underground connections within T5, supporting the efficient transfer of passengers and baggage across the terminal’s concourses, while also facilitating the routing of common utilities.
The tunnel system comprises a series of sub-tunnels that will house key infrastructure to support efficient airport operations. They include the Automated People Mover System and Baggage Handling System, as well as a Common Services Tunnel (CST) which will contain dry and wet utilities such as electrical power, communication systems and water services. The works also comprise a ventilation building that supports the CST, and provisions for a future underground infrastructure tunnel.
T5 is part of the larger Changi East development that includes Changi Airport’s third runway, as well as cargo complexes and other supporting aviation and ground transport infrastructure. The project is expected to be completed in the mid-2030s and will significantly boost Changi Airport’s capacity and operational capabilities to meet future demand.
