Procedure

Features
The process will include up to four stages as follows: Stage 1 - Invitation to Participate Questionnaire (ITPQ) with Conditions of Participation This stage follows the process set out in this document and the process set out in Section 11. Stage 2 – Initial Tender Submission Offer (ITSO) The Initial Tender Submission Offer (ITSO) requires tenderers to complete the tender response documents for the Quality Award Criteria and Pricing Schedule. 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 Stage 3 - Invitation to Participate in Negotiation (ITPN) Based 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. Points 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. Tenderers 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 Stage 4 – Final Tender Once 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. The Authority reserves the right to reject a Final Tender that: • Is dependent on a topic being the subject of negotiation (for example is incomplete or marked ‘for discussion’); or • Is incomplete and fails to include any specific proposals or responses; or • Moves 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) • Moves 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).
