Works for the replacement of the roof of the building that houses the fire group (GCI) of the biomethanization area and its interior sectorization, located in the COGERSA waste treatment center.

✓Place of performance is the Centro de Tratamiento de Residuos de Cogersa in La Zoreda, Serín (Gijón, Asturias), with postal address Carretera de Cogersa, 1125, 33697 Serín (Gijón).

✓The contractual execution period is 3 months, although the adjudicatario can offer a shorter period, which is then part of the award scoring.

✓No options or extensions (“prórrogas”) are foreseen.

✓Such as concerns award criteria and weighting, the contract is awarded on best quality‑price ratio under article 145 LCSP, combining economic and qualitative elements.

✓Quantifiable criteria (up to 97 points) are: price (criterion A, up to 92 points, scored by PO = (MO × VM) / OF, ensuring the lowest price gets 92 points), reduction of execution period (criterion B, up to 2.5 points, granting 2.5 points for one full month reduction from the 3‑month maximum; smaller reductions are not valued), and extension of contractual guarantee period (criterion C, up to 2.5 points, granting 1.25 points per full extra year beyond the minimum one‑year guarantee, up to 2.5 points total; partial years are not valued and the extension is capped at 3 years overall).

✓Qualitative criteria (up to 3 points) consist of the environmental resources memorandum (criterion D), rated 0, 1.5 or 3 points depending on sufficiency, detail and technical quality.

✓Offers are considered abnormally low if the offered amount is less than 70% of the average of all bids.

✓No variants are permitted.

✓Such as in relation to risks and special conditions, the PCAP includes an environmental special execution condition under article 202 LCSP: at the start of the works the contractor must present a waste minimization plan ensuring on‑site segregation of fractions and avoiding mixes that hinder reuse or recycling, supervised by the site management.

✓Non‑compliance triggers a specific penalty.

✓Payment regime is monthly certificates based on actually executed work and unit prices.

✓A definitive guarantee of 5% of the contract amount is required pursuant to the notice, and there is a contractual performance guarantee period of 1 year from reception, which may be voluntarily extended for scoring purposes.

✓Penalties cover delay in execution (by reference to article 193 LCSP), breach of the environmental/waste plan (1,000 € per infringement), defective execution (1,000 € per defect) and serious safety and health breaches (2,000 € per infringement), plus the general obligation to compensate damages.

✓No price revision is allowed (article 103 LCSP), and no modifications are foreseen during execution.

❓Subcontracting is implicitly possible under LCSP, but Cogersa explicitly disclaims any employment‑related responsibility: all staff assigned to the contract are exclusively dependent on the contractor, and there is no labour contract subrogation.

✓The tender documentation sets a validity period of the offer of 2 months (“Plazo de Validez de la Oferta: 2 Meses”).

❓The excerpts do not mention a specific question/clarification deadline or mandatory site visit; unless stated elsewhere in the full dossier, no special conditions on these points apply beyond general LCSP rules.

✓The place of performance appears both as “CTR de Cogersa” and “Centro de Tratamiento de Residuos de La Zoreda, en Serín (Gijón)”; these refer to the same facility, so there is no real conflict.

✓The guarantee regime shows a minimum one‑year contractual guarantee (section 11) and an award criterion allowing up to three years of total guarantee; this is complementary, not contradictory: the binding minimum is 1 year, with voluntary extensions to obtain extra points.

✓The solvency requirements are consistently described both in the PCAP and in the tender notice: bidders may choose between meeting the specific turnover and reference thresholds or presenting the stated official classification (Group C, subgroups 7 and 4, category 1).

❓Where minor wording differences appear (e.g. generic “CTR de Cogersa” versus full postal address), the more detailed notice description should be followed for practical purposes, but legally the PCAP and published notice together govern, and no excerpt provided indicates mutually incompatible obligations.
