Published description of the framework

All Lots of this Framework are multi-supplier lots with 2 suppliers per lot for lots 1 and 4 and 3 suppliers per lot for lots 2, 3, 5 and 6 at the Groups' discretion.

In the circumstance where more than one supplier has been awarded a place in a particular lot, suppliers will be ranked by their tender submission score according to the evaluation criteria set out in the Tender. The supplier with the highest score will be ranked first, the second highest ranked second and so on.

Work will be allocated and orders placed through the following process:

a. The Group will identify from the framework the highest ranked supplier for the required work.

b. The Group will contact the identified supplier with regards to capacity for the date, timescale and nature of the work required.

c. The Group will place an order with the supplier.

d. If the highest ranked Supplier is unable to fulfil the Group's requirements, then the Group will approach the next highest ranked supplier. This process will be cascaded down the ranks until the Group's requirements are met.

By exception the Groups reserves the right to access this Framework by mini competition.

Where an order is to be placed following the execution of a mini competition, the evaluation of offers will be made based on the following 'headline' criteria:

To reflect the variations of the work anticipated under this framework, the award criteria may differ from the award criteria used to set up the framework provided they are related to (i.e. derive from) the original award criteria.

In addition to changes to the award criteria it is also permissible to vary the weightings of the award criteria.

What this means for your bid
  • Price carries 40 of 100 points: a 10% discount moves about 4 points. The method statement decides this lot, not the discount.
  • “Compartmentation Surveys & Works and General Fire Safety Rectification…” is a framework: the contest is a place on its panel, up to 20 suppliers, not a single contract: call-offs may be direct or by further competition.

Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
