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 65% of the total evaluation score. All other prices will be scored proportionally.

- Price carries 65 of 100 points: a 10% discount moves about 6.5 points. This one is won on the number: sharpen the price before polishing the prose.
- “Service, Maintenance and Repair of Analytical Monitors” is a framework: the contest is a place on its panel, not a single contract: each call-off is a further competition, so the pricing contest starts after appointment.
Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
