What this means for your bid
  • Price carries 60 of 100 points: a 10% discount moves about 6 points. This one is won on the number: sharpen the price before polishing the prose.
  • “B930 (2026) Civil Engineering Works” is a framework: the contest is a place on its panel, up to 9 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.
