Published award criteria (2)
- Technical: Award Criteria as per tender documents
- Commercial: Award Criteria as per tender documents
- Price carries 45 of 100 points: a 10% discount moves about 4.5 points. Quality carries 55 of 100: the paper moves it further than the discount.
- “PA23 - UK4 - Tender Notice” is a framework: the contest is a place on its panel, not a single contract: each call-off is a further competition, so the pricing contest starts after appointment.
Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
