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 10–30 points depending on the lot; most lots put it at 10 points.
- “Supply and/or Install of Rooftop Solar Photovoltaic Systems and…” is a framework: the contest is a place on its panel, not a single contract.
Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
