Fort. St. John, B.C.- Work is underway to stabilize the north bank of the Site C project, following the development of a tension crack.
A two stage plan has been developed to deal with the 400-metre tension crack that appeared during construction of a haul road at the site.
The first phase will see a toe berm constructed to keep the area stable. That work is expected to be completed by the end of this month.
The second phase will see the safe removal of soil from the north bank so that work on the project can resume.
Geo technical experts have been conducting assessments over the past week and the information they have gathered indicates the slope around the 400 metre long crack is stable.
BC Hydro expects to complete the remediation work for the tension crack within the overall project budget and schedule.
BC Hydro says tension cracks are not unexpected in this area but that, “this particular crack requires attention due to its significant 400-metre length.”
