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 maximize opportunities for Indigenous businesses, labour, subcontracting and training. The Nunavut stream in particular will be exclusive to firms listed in the Inuit Firm Registry [https://inuitfirm.tunngavik.com]. Vendor Performance Management PWGSC will develop a vendor performance mechanism that is specific to the standing offers. The mechanism is designed to adjust the percentage distribution of call-ups according to the performance of each offeror.
