Changi Airport Group has awarded a contract for the construction of intra-terminal tunnels at Terminal 5 (T5) to a joint venture of Penta-Ocean Construction Co and Koh Brothers Building & Civil Engineering Contractor Ltd.
The award of the S$999m (€680m) contract follows the ground breaking of T5 last month. Construction is expected to take more than four years.
The intra-terminal tunnels will provide underground connections within T5 for the transfer of passengers and baggage across the terminal’s concourses, while also enabling the routing of common utilities.
The tunnel system comprises a series of sub-tunnels that will house key infrastructure to support 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.
CAG’s managing director for Changi East, Ong Chee Chiau, said the award of the T5’s intra-terminal tunnel works was another important development in the construction of T5 and the wider Changi East project.
“We are pleased to partner two highly reputable construction companies on the project – Penta-Ocean, recognised for its extensive expertise and technical proficiency in undertaking large-scale projects such as land reclamation within Singapore and internationally; and Koh Brothers, a key player in shaping Singapore’s infrastructure development with a strong track record in delivering complex, large-scale projects locally,” he said.
T5 is part of the larger, 1,080ha 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.
