Site preparation and stone column installation to prepare property for new BC Hydro Substation. The work included clearing and grubbing of 17,300m2 of land and off-site disposal of approximately 35,000m3 of soil. The ground improvement work included the installation of 1,591 stone columns to a depth of 25 meters below grade. Due to the steep grades and elevation changes across the site, a 10 meter high Lock-Block retaining wall and 2 Sierrascape retaining walls were constructed to provide a level footprint for the construction of the access road and substation. Additional work included the installation of drainage pipe, ditches and final site grading.
