Dalgrauer

This project was a seismic upgrade to an existing 6-storey indoor BC Hydro substation in downtown Vancouver, BC. The project involved reinforcing the entire rear wall down to the foundation. To achieve this, live 60 kv duct banks were undermined, shored, and stabilized in order to accomplish seismic work in the basement area.

Coquitlam Dam

Located at the end of Coquitlam Lake, the Coquitlam Dam was once home to the largest power diversion tunnel in the world. Kingston Construction was responsible for constructing a huge concrete gravity wall that ties into the native rock outcropping, overcoming extraordinary challenges due to extreme heights.
