Washwa Nu has managed major construction projects and large-scale civil works over the last few years. Among others, we participated in the construction and dismantling of a power substation in Waswanipi, the tree clearing of the substation, the right-of-way of the 315KV power line for Hydro Quebec as well as the remedial works at the end of the project. We also carried out paving works in the Community, performed maintenance works on Highway 113 on behalf of the MTQ, and completed the rebuilding of a bridge for the Osisko mining company.

Washwa Nu, along with their environmental and forestry team, has conducted several studies on behalf of the Cree First Nation of Waswanipi on various cases such as the implementation of the Marten Monitoring Program (Wapistan), the professional support for the review of the Windfall mining project impact study, as well as tailored wildlife monitoring training. All projects were completed with the involvement of local First Nations workers.
