What this means for your bid
- Price carries 30 of 100 points: a 10% discount moves about 3 points. The method statement decides this lot, not the discount.
- “UKRI-5155 Radioactive Waste Characterisation and Treatment Services” is a framework: the contest is a place on its panel, up to 3 suppliers, 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.
