Metro and its principals have a long history of work on dams, and have carried out condition assessment, supervision of construction, and restoration projects working as both a contractor and subcontractor.
Assessment work has included destructive and non-destructive testing as well as leakage testing.
Construction work has included various grouting and shotcrete applications.
The value was between 0 and 50,000 dollars. Metro Testing was directly involved in the shotcreting of the low level outlet (LLO) wall, overflow in-fill walls, in additional to providing materials testing and shotcrete consulting to the prime contractor, Graham Construction.
Cheakamus Dam underwent a large scale seismic upgrade which included the restoration of the bridge decks, LLO wall, LLO roof, and the construction of an emergency control structure and crane access platform.
