Competitive flexible procedure description
This procurement is being conducted as a Competitive Flexible Procedure in accordance with the Procurement Act 2023. Completion and submission of all documents will be conducted via the Authority's eSourcing system. Following the evaluation stages 1-5 referenced in the Bidder Pack, the authority reserves the right to reissue the technical evaluation questions, pricing schedule, or any part thereof to the two highest scoring bidders, or any other bidder, for a Best and Final Offer (BAFO). Please note that all bidders will be invited to submit improved responses on the same items. Bidders will have 10 calendar days to review, revise and resubmit their bid via Atamis. There will be a period of 5 calendar days for clarification questions. The exact dates of these periods and deadlines for submission will be shared with the relevant bidders. ! IMPORTANT - This is an optional stage for the Authority to ensure that the Most Advantageous Tender is selected, that the requirement has been fully understood, and that bidders are provided a fair chance to compete where the Authority does not feel ready to award after Stage 5 evaluation. Bidders should submit their best possible tender and price in the first instance, as it is not guaranteed that this stage will be used.
