  • How the procedure runs: This procurement will follow a simple two stage competitive flexible procedure, without negotiation or dialogue. The Contracting Authority will carry out a PSQ as the first stage to shortlist a number of suppliers, evaluating suppliers on a combination of Qualification & Technical questions & an assessment of excludable suppliers, connected persons or sub-contractors in accordance with PA 2023. This is available on the DSP & will be used to down-select from an anticipated maximum of 6 suppliers to invite to tender. At the second stage, the Contracting Authority will issue an ITT to the shortlisted suppliers & invite them to submit tenders. If at the first stage it's established that only ONE supplier is shortlisted, letters will be issued to inform unsuccessful suppliers the procurement under the competitive flexible procedure would be cancelled & would switch to Direct Award. Once the ITT has been published to those successful at PSQ, a clarification process will be used during the tender period to allow for suppliers to ask the Authority questions. A summary of the award criteria is in this notice and will be explained in the Tender Evaluation Strategy, which will be published in the DSP, with the ITT. The Authority reserves the right to refine the award criteria before and - where negotiation/final tenders are used - during the Tender period in accordance with section 24 of the Procurement Act 2023. This may include revision to the weightings of the sub-criteria. During this stage there will be no negotiation or dialogue with any shortlisted suppliers.
  • No preliminary market engagement: No market engagement required for this procurement.
