$267-million B.C. water tunnel project awarded

BURNABY, B.C. — A $267-million contract to build the Second Narrows Water Supply Tunnel Project in Vancouver has been awarded to a joint venture between Aecon and Traylor Bros Inc.

The project scope includes building two shafts, one on each side of Burrard Inlet, connected by a 1,100 metre tunnel. The north entry shaft will be in North Vancouver and approximately 60 metres deep, while the south exit shaft will be in Burnaby and approximately 110 metres deep.

Crews will use a tunnel boring machine launched from the shaft on North Vancouver to dig the tunnel. Once the tunnel is drilled, three steel watermains will be installed inside the new tunnel and connected to underground valve chambers at each shaft site, and into the region’s drinking water system.

Work will begin this month and is expected to wrap up by the end of 2023.

The tunnel will be one of five new water supply tunnel crossings in the region built to withstand a major earthquake. When complete, the tunnel will increase the capacity of the existing system to ensure the continued, reliable delivery of clean, safe drinking water in a growing region and will meet current seismic standards.

“We look forward to successfully and safely delivering this complex, multi-year project for Metro Vancouver to ensure the continued, reliable delivery of clean drinking water to member jurisdictions,” said Jean-Louis Servranckx, president of Aecon Group Inc., in a press release. “This award further advances Aecon’s recognized reputation as a partner-of-choice for tunnelling projects, while expanding our solid presence in Western Canada working on large-scale critical infrastructure projects.”
