PWGSC plans to develop the upcoming multidisciplinary environmental services Request for Standing Offers (RFSOs) with the following structure:
Publish four RFSOs on the CanadaBuys tender opportunities website, each aligned to a distinct geographic area and supplier eligibility requirements:
1. Prairies RFSO: Alberta, Saskatchewan, and Manitoba
2. Prairies PSIB RFSO: Alberta, Saskatchewan, and Manitoba, limited to Indigenous suppliers in accordance with the Procurement Strategy for Indigenous Business (PSIB)
3. Northwest RFSO: Northwest Territories and Yukon
4. Nunavut RFSO: Nunavut Settlement Area, limited to Inuit firms registered on the Inuit Firm Registry
Each RFSO will allow consultant firms to qualify for a DISO for the geographic area covered by that RFSO.
? Consultants may submit offers under more than one RFSO.
? Call-up distribution within each standing offer will be based on pre-determined percentages.
? Each standing offer will include two tiers, with separate call-up procedures as follows:
1. For requirements up to $100,000 (including applicable taxes), PWGSC may either:
i. issue the call-up to the next firm on the rotation (rotational call-ups),
ii. select the Offeror of their choice (selective call-ups)
iii. compete the call-up on the basis of a work plan, level of effort, cost of disbursements and/or travel or Indigenous/Inuit commitments (competitive call-ups).
2. For requirements above $100,000 (including applicable taxes), PWGSC may either:
i. issue the call-up to the next firm on the rotation (rotational call-ups),
ii. direct a call-up to a firm with ‘best-fit’ justification (‘best fit’ call-ups), or
iii. compete the call-up on the basis of a work plan, level of effort, cost of disbursements and/or travel or Indigenous/Inuit commitments (competitive call-ups /the pre-established unit rates of the standing offers will be respected).
Each issued call-up will affect the order of priority of rotational call-ups to attain the ideal business volume distribution.
Modern Treaties/Comprehensive Land Claims Agreements (CLCAs)
Many of the multidisciplinary environmental services tool call-ups will be subject to modern treaties/CLCAs, which define the land and resource rights of Indigenous signatories and are intended to improve the social, cultural, political and economic well-being of the concerned Indigenous peoples. Accordingly, the RFSOs will include socio-economic benefits criteria designed to maximi
