- Social Value: 10%

- Technical: 70
- Social Value: 10
- Price: 20
- Staff
- Names and qualifications of delivery staff must be submitted
- Price carries 20 of 100 points: a 10% discount moves about 2 points. The method statement decides this lot, not the discount.
- “Post-Closure Safety Case Framework” is a framework: the contest is a place on its panel, up to 5 suppliers, not a single contract.
Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
