Peace Canyon Dam

A 32 year-old power dam in northern BC needed a roof upgrade and a skylight replacement.

Roof upgrade and a skylight replacement

Topside was brought in to co-design the re-roofing project. The project specifications were centered on safety and risk reduction for both the people and building. Careful discussions with the owners and their engineers continued for two years. We ultimately determined that re-purposing the existing roof membrane to become the new vapour barrier would allow the risk of water intrusion on such a large, critical facility to be considerably reduced.

It was a demanding project that required cooperation and constant communication with several departments of Hydro along with the roofing contractor and sub-contractors. Several critical details of the final design came out of the due diligence discussions that we initiated.

The roof was successfully completed in 2012, and carries a 10-year guarantee.
