Lot distribution rule: The supplier with the highest overall score for both quality and price (Total of Columns 1, 2 and 3) in each Lot will win the evaluation. You can bid for both Lots, or an individual Lot. If bidding for one Lot you must be able to support the winning supplier for the other Lot with spare parts at the prices submitted in your bid.

Price carries 30 of 100 points: a 10% discount moves about 3 points. The method statement decides this lot, not the discount.

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