Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 45. The category anchor is Installation of windows (45421132); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.

“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.

Price-outcome signal

Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.

The ITSO must be capable of being accepted without further negotiation. If deemed applicable and capable of being accepted, the Authority may choose not to proceed with further negotiations and award immediately to a Tenderer based on the Most Advantageous Tender (MAT) criteria\nStage 3 - Invitation to Participate in Negotiation (ITPN)\nBased on the evaluation of Stage 2 and if a contract is not awarded, Tenderers may be shortlisted by the Authority and invited for further negotiation/dialogue. The purpose of the negotiations will be to consider the ITSO responses submitted by the Tenderers with a view to improving the content of the Final Tender.\nPoints of clarification provided by the Authority during the negotiation will be shared with all Tenderers on an anonymous basis with the exception of commercially sensitive information which will not be shared.\nTenderers may be asked to submit revised versions of responses to questions following the negotiation phase. Interim submissions will not be evaluated by the Authority but are intended to form the basis of further negotiations with the Tenderers if required\nStage 4 – Final Tender \nOnce the Authority is satisfied with the negotiated terms with Tenderers within the ITPN stage, the remaining shortlisted Tenderers will be asked to submit their Final Tenders, which must be capable of acceptance. The Final Tenders will incorporate any changes and/or improvements as a result of the negotiation stage.\nThe Authority reserves the right to reject a Final Tender that:\n•\tIs dependent on a topic being the subject of negotiation (for example is incomplete or marked ‘for discussion’); or\n•\tIs incomplete and fails to include any specific proposals or responses; or\n•\tMoves away from pricing provided in the Initial Tender or improved pricing settled in negotiation stage (moves away in this context means ‘worsens’ – i.e. it is open to Tenderers to submit improved positions or more economically advantageous tenders in the Final Tender)\n•\tMoves away in a Final Tender from a proposal discussed and settled in negotiation stage (moves away in this context means ‘worsens’ – i.e. it is open to Tenderers to submit improved positions or more economically advantageous tenders in the Final Tender)."

The ITSO must be capable of being accepted without further negotiation. If deemed applicable and capable of being accepted, the Authority may choose not to proceed with further negotiations and award immediately to a Tenderer based on the Most Advantageous Tender (MAT) criteria\nStage 3 - Invitation to Participate in Negotiation (ITPN)\nBased on the evaluation of Stage 2 and if a contract is not awarded, Tenderers may be shortlisted by the Authority and invited for further negotiation/dialogue. The purpose of the negotiations will be to consider the ITSO responses submitted by the Tenderers with a view to improving the content of the Final Tender.\nPoints of clarification provided by the Authority during the negotiation will be shared with all Tenderers on an anonymous basis with the exception of commercially sensitive information which will not be shared.\nTenderers may be asked to submit revised versions of responses to questions following the negotiation phase. Interim submissions will not be evaluated by the Authority but are intended to form the basis of further negotiations with the Tenderers if required\nStage 4 – Final Tender \nOnce the Authority is satisfied with the negotiated terms with Tenderers within the ITPN stage, the remaining shortlisted Tenderers will be asked to submit their Final Tenders, which must be capable of acceptance. The Final Tenders will incorporate any changes and/or improvements as a result of the negotiation stage.\nThe Authority reserves the right to reject a Final Tender that:\n•\tIs dependent on a topic being the subject of negotiation (for example is incomplete or marked ‘for discussion’); or\n•\tIs incomplete and fails to include any specific proposals or responses; or\n•\tMoves away from pricing provided in the Initial Tender or improved pricing settled in negotiation stage (moves away in this context means ‘worsens’ – i.e. it is open to Tenderers to submit improved positions or more economically advantageous tenders in the Final Tender)\n•\tMoves away in a Final Tender from a proposal discussed and settled in negotiation stage (moves away in this context means ‘worsens’ – i.e. it is open to Tenderers to submit improved positions or more economically advantageous tenders in the Final Tender)."
