Leighton Asia, a CIMIC Group company, has won a Deep Tunnel Sewerage System Phase 2 contract worth AUD470m ($378m) from PUB, Singapore’s national water agency. 

Under the contract, Leighton Asia will be responsible for designing and construction of almost 7.9km of sewer tunnels, each with an internal diameter of six metres, as well as shafts, hydraulic structures and other facilities associated with the sewage conveyance system.

Construction work is expected to begin in October 2017 while the project completion is scheduled by mid-2023.

CIMIC Group CEO Adolfo Valderas said: “The award of one of the major tunnelling packages for the Deep Tunnel Sewerage System in Singapore demonstrates CIMIC’s diverse capability, drawing together the expertise of Leighton Asia and CPB Contractors to deliver large and critical infrastructure assets.

“It is our privilege to contribute our innovative and cost-effective design and construction methodologies to support Singapore’s continued growth, and fulfil the quality and sustainability expectations of its people and communities.”

CPB Contractors and Leighton Asia managing director Juan Santamaria said: “Our team has extensive international experience in delivering major tunnelling and complex energy and resources infrastructure, as well as decades of local experience in building important commercial and social infrastructure in Asia.

“We value the opportunity to contribute our key resources and expertise to safely and effectively deliver a project of this scale and complexity.”

Earlier in 2008, the first phase of the project was completed. Now the second phase will be completed through various works packages.

The project aims to complete 40km of deep tunnels and 60km of link sewers, as well as associated hydraulic structures and air management facilities.
