Each project must be comparable to the Rowley Way Estate Better Homes Internal Refurbishment Works in terms of:
• Scale (large residential estate, approx. 500 occupied dwellings, with ancillary buildings)
• Value (£11.4m)
• Location (Grade II Listed Building - for at least two projects)
For each case study, provide the following project details:
• Project title
• Project address
• Full name and registered address of the Employer
• Employer contact details (name, role, organisation, email, and phone number - references may be taken up)
• Form of Contract used (e.g., JCT D&B, JCT SBC, NEC ECC, etc.)
• Contract start and completion dates
• Contract Sum at award
• Delay/Liquidated Damages - whether any were deducted and total value
• Health and Safety - number of RIDDOR reportable incidents and near misses
• Disputes - whether any arose, how they were resolved (e.g., through adjudication, mediation, or other).
For each case study, you must also address the following qualitative evaluation criteria:
Assessment Criteria (Total: 100%)
1. Project Delivery (50%)

• How you managed engagement with key stakeholders (including the client team, local authority, consultants, and neighbours and any others) throughout the contract period
• How you managed phasing of the works.
2. Coordination of Works (10%)
Explain how you approached coordination of intrusive heating works with other contractors carrying out window and internal refurbishment works. How were the works sequenced to minimise return visits and protect finished areas.
3. Quality Assurance (20%)

Procedure
Procedure type
Competitive flexible procedure
Competitive flexible procedure description
3.4. The process will include up to four stages as follows:
3.4.1. 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.
3.4.2. 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
3.4.3. 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
3.4.4. 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).
Justification for not publishing a preliminary market engagement notice
The scope of the market is big enough for preliminary market engagement to not be required.
