Metro Vancouver (Greater Vancouver Water District) has awarded a $267 million contract for the Second Narrows Water Supply Tunnel project in British Columbia to a joint venture between Aecon (40 per cent) and Traylor Bros Inc. (60 per cent).
The scope of work includes construction of 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.
Work to replace existing marine crossings of Burrard Inlet has been underway for several years. Seismic vulnerability studies undertaken in the late 1990s and early 2000s showed that they crossings were vulnerable to damage from earthquake. The new design, work on which began in 2009, will ensure a more resilient system is put in place that would be able to withstand significant seismic activity.
“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 and chief executive officer of Aecon Group Inc.
Work will commence in November 2018 and the project is expected to reach completion by the end of 2023.
