What it takes to win
i

Evaluation split and conditions of participation as published; the tender pack may add more
How bids are scored · same split on all 2 lots
Quality: 50%Price: 50%
Published award criteria (2)
  • Price
  • Quality: See T190 CfT on eTendersNI for quality criteria breakdown
Lot distribution rule: Supplier states their Lot preference in their tender submission should they rank first in both.

No conditions of participation were published on the notice; check the tender documents.

What this means for your bid
  • Price carries 50 of 100 points: a 10% discount moves about 5 points. This one is won on the number: sharpen the price before polishing the prose.
  • Turnover usually expected: about £18,982,664 per lot (twice each lot's annual value).

Price arithmetic assumes straight proportional scoring; the tender pack may use another formula. Turnover is an indicative market norm (≈2× annual value), not a published condition.
