Around Town: Update on John Hart Replacement Project
Work is progressing on time at the John Hart Dam generating station replacement project in Campbell River. The work site is expanding as more aspects of the project come under construction, and various components of the project begin to come together.
This photo from BC Hydro shows construction on the cofferdam, an important step in the overall replacement project. This will be the site of the new water intake tunnel.
Steel bracing has been installed inside the cofferdam, which has been under construction since this summer, and a staged de-water process has begun. Site excavation at the cofferdam is in progress. This will be the site of the new water intake tunnel for the underground generating station.
Components of the turbine generator will begin to arrive this month, including draft tube elbows, in preparation for installation late next year. Alstom, a European company with some fabrication in Quebec and China, was awarded the design and installation of the draft tube elbows in 2014. These tubes are roughly 10 metres in length and 7 metres in diameter, and will arrive by truck due to size limitations of train tunnels across Canada!
BC Hydro has completed a second construction video showing work on site and progress to date. You can view the video on Youtube here: https://youtu.be/wOAZFZgiBok.
