- Price carries 40 of 100 points: a 10% discount moves about 4 points. The method statement decides this lot, not the discount.
- “Sewer Sealing Request for Information” is a framework: the contest is a place on its panel, up to 8 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.

Depending on the insights gathered, we may follow up with:
One-to-one meetings (either in person or online),
A live Marketplace event or townhall session (either in person or online),
and/or a second RFI, if deemed necessary.
The initial RFI is scheduled to be issued on 17th October 2025.
