Port Mann Main No. 2

Port Mann Main No. 2

Scope

Michels built a 148-metre long, 1.8-metre diameter tunnel under the Mary Hill Bypass, a major four-lane highway in the Vancouver metropolitan area, to house a 1.5-metre diameter water main.

Microtunneling proved to be an effective method for constructing a tunnel in ground conditions that ranged from sandy/silty with layers of gravel and wood debris and a high pressure water table that sits just 2 metres below the surface. Tidal influxes from the nearby ocean also presented challenges.

Projects

Michels Canada completed a 117-metre long, 2,121-mm diameter tunnel as an outfall for a new wastewater treatment plant on Vancouver Island.
