Please ensure that all questions in the PQQ documentation are completed in full. Stage 2: Request for Proposal (RFP) Shortlisted tenderers from the PQQ stage will be invited to submit detailed proposals on how they will deliver the requirement. These proposals will be evaluated and scored to determine the supplier offering the best overall value for the contract. Pricing will be evaluated based on the information provided in the Pricing Matrix. The totals from the evaluated worksheets will be consolidated into a Summary table, which will provide an overall price for comparison. The bidder offering the most advantageous price will be considered for award of the call-off contract. Pricing will be scored relative to the lowest feasible bid. The lowest compliant price will receive the maximum score of 100 points. Price will account for 30% of the total evaluation score. All other prices will be scored proportionally. Following the RFP stage, Severn Trent will conduct clarification meetings and supplier presentations with the final two shortlisted bidders to ensure a full understanding of their proposals and to clarify any aspects of the submissions. Severn Trent also reserves the right to hold negotiation meetings with shortlisted bidders as part of the tender process. Following these activities, Severn Trent reserves the right to conduct negotiations in accordance with the Utilities Contracts Regulations 2016. Following negotiations, bidders may be invited to submit a Best and Final Offer (BAFO). The BAFO stage provides bidders with the opportunity to refine their proposals based on clarifications, presentations, and negotiations. BAFO submissions will be evaluated against the award criteria set out in this RFP documentation. Please note that the evaluation of BAFO may result in changes to the scores previously allocated to initial written proposals.
