If Submissions are received from Consortia, the Partner Councils reserve the right to require every Consortium Member to enter into the Contract on a joint and several basis. Where a Consortium Member is relying on another entity for the purpose of financial standing, parent company guarantees or other form of security (acceptable to the Partner Councils acting reasonably) will be required to guarantee that Consortium Members’ liabilities under the Contract.

The Partner Councils reserve the right to disqualify any consortium which changes its composition after pre-qualification without the Partner Councils prior consent.

Publisher note: The Partner Councils reserve the right to reject or disqualify a Bidder where the Bidder or any Bidder is an economic operator excluded under Regulation 58 of the Public Contracts (Scotland) Regulations 2015 at any stage of the selection process. Any change in Consortium Members or Reliance Entities after SPD response deadline must have prior agreement of the Partner Councils. Appendix C of the SPD Instructions provides guidance on the sections of the SPD requiring completion by each Consortium Member and Reliance Entity. When answering Question 2.A.3 in the SPD Bidders should detail their Company Number or alternative EU Registration Number (if applicable). The Contract will not be divided into lots due to its complexity. A Competitive Procedure with Negotiation is being used because of the complexity, the legal and financial makeup of the Facility and the risks which are attached to these; and the technical specifications of the contract cannot be established with reference to a standard common technical specification. Bidders must self-certify adherence to selection and exclusion criteria via the SPD. Relevant evidence and certificates, which support the declarations made in the SPD, shall be provided by the Bidder at ITT stage. When completing the SPD, Bidders must have regard for the specific selection requirements detailed in Section III of this Notice. Following assessment of SPD Submissions we intend to invite 3 Bidders to submit a tender. The buyer is using PCS-Tender to conduct this PQQ exercise. The Project code is 31998.
