A rockslide in a remote coastal region of British Columbia damaged penstock essential to providing water to Alterra Power Corp.’s hydroelectric facility. The company, through the Toba Montrose General Partnership, required a contractor that could move quickly during the region’s short construction season to stabilize the mountainside and replace the damaged penstock.
Barnard Construction of Canada Ltd. responded on a fast-track schedule to remove and replace approximately 1,100 LF of 96-inch-diameter steel penstock that was damaged in the naturally occurring rockslide. This repair project included rock removal, slope stabilization and drilling and blasting in addition to the penstock construction. The project took place in the remote Sunshine Coast region of British Columbia where the logistics of material and equipment delivery were solely by ocean delivery. The project also required establishment of a temporary remote camp for living quarters.
