BC Hydro says it hit a major milestone at Site C this week, finishing roller-compacted concrete placements in the upper spillway buttress seven months ahead of schedule.
Crews finished the work on Wednesday, Oct. 30, BC Hydro said.
"The spillways buttress is one of three large concrete buttresses – or foundations – BC Hydro is building to support the Site C powerhouse, spillways and the dam itself," BC Hydro said in a news release.
"Together, they are a key component of the project’s design, and will ensure dam stability, including in the unlikely event of a major earthquake."
Crews placed 585,516 cubic metres of roller-compacted concrete this year, and have placed more than 1.2 million cubic metres of RCC on the project to date, BC Hydro said.
The powerhouse buttress was completed in October 2018, and the dam buttress is scheduled to begin in 2020, BC Hydro said.
