Procedure

Features
This procurement will be conducted using the Competitive Flexible Procedure under Section 20 of the Act. The process will be carried out in two stages: Stage 1 – Invitation to Participate (Selection) All suppliers must complete the Procurement Specific Questionnaire (PSQ). Submissions will be assessed against pass/fail criteria (financial capacity, insurance, legal capacity, technical ability, health and safety accreditation) and scored project-specific questions. The top five highest-scoring suppliers will be invited to progress to Stage 2. A sixth supplier may be invited if scores between 5th and 6th are within two percentage points. Stage 2 – Invitation to Submit a Tender (Award Stage) Shortlisted suppliers will be invited to submit full tenders. Responses will be evaluated on Quality (60%) and Price (40%), in line with the published award criteria. Quality will be assessed through written method statement responses, with areas covering service delivery, staffing competence, compliance, communication, technology integration, social value, and innovation. Price will be evaluated using a relative scoring model, with the lowest compliant bid achieving maximum marks. Moderation and Evaluation Each submission will be assessed individually by the Contracting Authority’s evaluation panel. Provisional scores will be moderated to agree a final consensus score. A non-scoring moderator will ensure accurate recording of the evaluation. Interviews and Due Diligence Interviews may be conducted to validate tender responses. The Authority may also undertake due diligence checks, including financial checks, reference site visits, and verification of technical competence. Scores may be adjusted based on interview outcomes. Contract Award The contract will be awarded to the supplier submitting the Most Advantageous Tender (MAT) following moderation, interviews (if applicable), and due diligence. The Authority will issue assessment summaries to all participants and observe the mandatory standstill period before contract award. Contract Details The successful supplier will enter into a JCT MTC 2024 contract, supported by service levels and KPIs. No negotiation on terms will be permitted, and supplier submissions will form part of the final contract.
