Around Town: Construction Report for John Hart Dam Generating Station Replacement Project
Drilling for the surge chamber at the John Hart Dam generating station replacement project has begun, along with blasting for the 1,575 metre power tunnel from the powerhouse to the reservoir and at the tailrace area. One sealing cell at the cofferdam is complete, and the other is still under construction.
This photo provided by BC Hydro shows work on the cofferdam at the John Hart Dam Generating Station replacement project. Work on the sealing chambers is expected to be complete in December.
Drilling, blasting and excavation for construction of the tailrace will continue through the month of October. The cofferdam is expected to be complete in December. Retaining walls will then be built and the area dewatered. Powerhouse vertical excavation is expected to be complete in March and concrete work will begin in April of next year.
Tree removal is almost complete for the construction access road and surge tank work area. Overburden will be removed in October to access the subgrade below and allow for continued construction and preparation for the surge tank.
