Letter of Interest / Advance Notice to Industry Multidisciplinary Environmental Services RFSO

Solicitation # EW699-260375

Public Works and Government Services Canada (PWGSC) intends to establish new Departmental Individual Standing Offers (DISOs) for multidisciplinary environmental services to replace expiring contracts. This advance notice, which includes an amendment to remove Yukon from the requirement, outlines a procurement strategy for the Western Region covering environmental impact assessments, permitting, biological studies, archaeological assessments, environmental management of federal facilities, contaminated sites consulting, and remediation planning. The procurement will be structured into four distinct Requests for Standing Offers (RFSOs) based on geographic areas and specific eligibility requirements: a Prairies RFSO for Alberta, Saskatchewan, and Manitoba; a Prairies PSIB RFSO limited to Indigenous suppliers; a Northwest RFSO for the Northwest Territories; and a Nunavut RFSO exclusive to firms registered on the Inuit Firm Registry. The upcoming RFSOs will incorporate socio-economic benefits criteria to maximize opportunities for Indigenous businesses, labor, and training, in alignment with modern treaties and Comprehensive Land Claims Agreements. Call-up procedures will be tiered based on contract value, with requirements up to $100,000 allowing for rotational, selective, or competitive call-ups, while requirements exceeding $100,000 may utilize rotational, best-fit, or competitive methods. Additionally, PWGSC plans to implement a vendor performance management mechanism to adjust the distribution of call-ups based on individual offeror performance. The Buy Canadian Procurement Policy will also apply to these requirements. An optional pre-tender information session is scheduled for September 22, 2026, via Microsoft Teams.
