How this buyer will score bids.
The evaluation criteria and weights exactly as published on the notice, grouped by family (price, quality, social value and so on).
Lots publish different evaluation splits; there is no single procedure weighting.
- Price carries 50 points on every lot: a 10% discount moves about 5 points.
- “Control and Automation” is a framework: the contest is a place on its panel, 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.
