The Gitga'at Power Limited Partnership, acting on behalf of the Gitga'at First Nation, is soliciting proposals for Independent Environmental Monitor (IEM) services for the Gitga'at Power Project in British Columbia. The IEM will be retained by the Owner but must maintain strict independence from the Owner, contractor, and designer, reporting directly to the British Columbia Ministry of Water, Land and Resource Stewardship. The scope of work spans several phases, including pre-construction review of environmental plans, field monitoring of in-stream and riparian works during construction, monitoring of first diversion and ramping, and overseeing site restoration and final close-out reporting. Compliance is measured against the Water Sustainability Act, the project's Water Licence, and the Construction Environmental Management Plan. Submissions must be delivered as a single searchable PDF by December 4, 2026, and must not contain any pricing information, as the final agreement terms will be negotiated with the selected respondent.

Key personnel must hold professional registrations appropriate for British Columbia. Respondents are required to provide a submission form, project reference form, and a conflict of interest declaration, while ensuring the total proposal does not exceed 20 pages.
