North West Leicestershire District Council:
Replacement of Double Glazed Units Invitation to Quote

Background
North West Leicestershire District Council has a variety of outstanding deficient
double glazed units that require replacement in a large number of domestic
properties across a wide geographical area. These have been batched and now
require attention. As a result, NWLDC needs to carry out urgent repairs as quickly as
possible.

Outputs and Deliverables
Measure all units accurately and replace as required. Glazing to units shall comprise
hermetically sealed flat units of 2 no. leaves of 4 mm clear or obscured glass air filled
cavities of not less than 16 mm width, the inner leaf to incorporate a low-E coating.
The thermal performance of glazing used will be such that it will enable finished units
to achieve a thermal performance (U-value) of not more than 2.0 W/m2K.

Evaluation / Selection of provider
The Council reserves the right to write to or meet with bidders for clarification on any
points included within their submission. The points discussed may result in scores
being adjusted either up or down. We also reserve the right not to award any
contract, in whole, or in part.
The evaluation of the quotations submitted will be done using the criteria and
methodology set out below:
Financial Evaluation
The financial element is weighted at 70% of the overall evaluation. It is anticipated
that fees will follow the guidelines set out below:
The submission with the lowest % fee will be awarded the full score of 70.
All other bids are scored using the formula: Bid’s score = (maximum score available)
x (lowest total cost / bid price
So for example, where there are 70 points available:
Bidder 1 submits the lowest price of £50
Bidder 2 submits a price of £65
Bidder 1 will score 70, as their price is lowest
Bidder 2 will score 53.84, based on the formula 70 x (50÷65)
