Framework operation description
Call Off Method 1 - Without Re-opening Competition Direct Award based on Ranking:
Contracts which are awarded under this Framework Agreement without re-opening competition will be done so in accordance with the objective conditions provided for in the initial Tender Documents.
Contractor/ Suppliers will be ranked on the basis of the initial quality/price evaluation of the concluded Framework Agreement. The highest ranked Supplier may be offered each Contract on the basis of these rankings (the highest ranked Contractor/ Supplier may be selected to perform a specific Contract).
If the Contractor/ Supplier who was ranked highest is not able to undertake the Contract, the Council may offer the Contract to the next ranked Contractor/ Supplier. The Council may repeat this process until the Contract is fulfilled or there are no further organisations on the Framework Lot qualified to fulfil it.
Call Off Method 2 - Re-opening of competition amongst all Contractor's/ Suppliers on the Framework:
Contractor/ Suppliers awarded a position on the Framework Agreement may be invited, where applicable, by the Council to participate in a Further Competition by way of an Invitation to Tender through the Council's electronic procurement website, YORtender.
This procedure is anticipated to be used where:
• the requirements of the specific Contract differ from the requirements as detailed in the Framework Documentation
• submitted Framework rates cannot be accurately assigned to the specific Contract
• the specific Contract is estimated to be higher than £50,000.00 for Loft Insulation Services or £100,000.00 for Cavity Wall Insulation Services.
Where Parties to the Framework Agreement are invited to supplement their initial Tender to compete under a Further Competition from this Framework, the evaluation of these Tenders will be based on a ranged Price, Quality and/or Social Value split which will be formulated more precisely and communicated in the published Invitation to Tender document. This range allows Award Criteria percentages to be determined appropriately in accordance with the complexity of each specific scheme.
In the event that the Contract is estimated to be higher than a value of £100,000.00 (one hundred thousand pounds), in line with the Council's Social Value Policy, the Council reserve the right to include Social Value as part of the award criteria.
Provided that the Tender is submitted fully in accordance with the requirements set out within the Council's Specification and the additional Tender Documentation, the Contract will be awarded on the basis of the Most Advantageous Tender based on Quality, Price and/or Social Value
Quality: 0% - 90%
Price: 10% - 100%
Social Value: 0% - 10%
For the avoidance of any doubt, one or more of the above Award Criteria may be applied to any Further Competition from this Framework.
Notwithstanding the fact that the Council has followed the procedure set out above for competed Works, the Council may cancel, postpone, delay or end the procedure without placing an Order for Works or awarding any Contract. Nothing in this Framework Agreement shall oblige the Council to place any Order for Works.
Evaluation of the further competition tender response:
Tenderers will have their Pricing Schedule and/or their Quality Method Statements (and where applicable, any Social Value proposals) evaluated using the Award Criteria and the Evaluation Model set out within the Further Competition Document.
The Quality and Pricing information provided and requested in the Further Competition documentation will be formulated more precisely for each Specific Contract.
Re-assessment of minimum selection criteria:
Prior to the award of any Specific Contract, the Council reserves the right to re-assess the Contractor/ Supplier to confirm that the Contractor/ Supplier still meets the Council's minimum selection criteria at the time of the proposed award.
Assessment of current capacity:
Prior to the award of any Specific Contract, the Council reserves the right to assess the existing workload of the Contractor/ Supplier to confirm that the Contractor/ Supplier has the necessary capacity to undertake the new Contract alongside any current commitments.
