Aecon-Flatiron-Dragados-EBC Partnership (AFDE)
Peace Region, British Columbia
December 2017 – Ongoing
The Site C Clean Energy Project (Site C Project) is being constructed by British Columbia Hydro and Power Authority (BC Hydro) to provide 1,100 megawatts of energy capacity and approximately 5,100 gigawatt hours of energy each year into the Province of British Columbia’s (BC) integrated electricity system, consistent with the BC Clean Energy Act. The Site C Project is the third dam and generating station on the Peace River, located approximately 7 kilometres southwest of Fort St. John, which resides within the First Nations Treaty 8 Territory and the Peace River Region of BC. The AFDE Partnership was contracted by BC Hydro to construct the Generating Station and Spillways Civil Works contract of the Site C Project.
The Generating Station and Spillways Civil Works includes construction of the following permanent and temporary infrastructure:
- Generating station and powerhouse;
- Water intakes, penstocks and spillways;
- Laydown areas for batch plant, water treatment settling ponds, formwork storage, carpentry shop, welding and rebar shops, main warehouse, and fuel yard;
- Temporary water intake and outfall installation;
- Aggregate crushing and storage area; and
- Office areas.
Construction of the GSS commenced in spring 2018 with the target completion date of summer 2023.
Additional scope of work also completed by AFDE for the Site C Project include:
- Moberly debris control structure;
- Peace River debris boom; and
- Right bank foundation enhancements.
