Changi Airport Group (CAG) has awarded a contract worth S$999m for the construction of intra-terminal tunnels at Terminal 5 (T5) to a joint venture between Penta-Ocean Construction Co., Ltd. and Koh Brothers Building & Civil Engineering Contractor (Pte.) Ltd. The project, following the recent groundbreaking of T5, is expected to take over four years to complete.
The intra-terminal tunnels will facilitate efficient passenger and baggage transfer across T5’s concourses and support the routing of common utilities. The tunnel system will include the Automated People Mover System, Baggage Handling System, and a Common Services Tunnel (CST) for utilities like electrical power and water services. Additionally, a ventilation building and provisions for future infrastructure are part of the project.
Ong Chee Chiau, CAG’s Managing Director for Changi East, stated, “The award of the T5’s intra-terminal tunnel works marks another important development in the construction of T5 and the wider Changi East project. These tunnels will enable the smooth and efficient movement of passengers, baggage and services.”
Penta-Ocean, known for its expertise in large-scale projects, and Koh Brothers, with a strong track record in infrastructure development, are key players in this venture. Osamu Hidaka of Penta-Ocean expressed honour in being awarded the project, emphasising collaboration and advanced technologies. Paul Shin of Koh Brothers highlighted the milestone in their commitment to Singapore’s transport infrastructure.
The T5 project is part of the broader Changi East development, which includes a third runway and cargo complexes, aiming to enhance Changi Airport’s capacity and operational capabilities by the mid-2030s.
