Corbeau Hydroelectric Station Demolition and Remediation

Kitigan-Zibi, QC

Decontie Milestone Inc. (DMI) a joint venture formed by Decontie Construction Inc. and Milestone Environmental Inc., was contracted to demolish, and decommission a former run of the river Hydro Québec hydroelectric power station, the Corbeau Hydroelectric Station located adjacent to the Anishinabe (Algonquin) community of Kitigan Zibi. Decontie and Milestone worked together seamlessly to conduct specialty services such as environmental remediation of hazardous substances, construction cofferdams, and demolition of the building itself alongside a trusted subcontractor, Demolition Plus for heavy civil earthworks and demolition services. A project team with members of the Anishinabe (Algonquin) community of Kitigan Zibi was formed filling 30 new jobs in heavy equipment operation, skilled trades, administration, and site supervision.
