Works of execution of metal roofs and photovoltaic solar installation in parking areas and warehouse of the Machinery Park of the Road Cleaning and Collection Service of the R.S.U. of the southern area of the C.A.M.

✓The execution period is six months, and the place of performance is Melilla (sub‑territorial code ES640).

✓The text clarifies that the contract is not divided into lots, justified by the need for centralized technical and functional control of a single works package, and that no provisional guarantee is required, although there is a definitive guarantee of 5% and an additional complementary guarantee of 5% of the contract amount.

✓Such as the award criteria and weighting, the contract uses an open procedure with multiple criteria aimed at best quality‑price ratio.

✓The overall scoring is 100 points, split into 60% for quantitative criteria (price) and 40% for qualitative criteria evaluated by judgement (Memoria Constructiva, Programa de Trabajo, Cartas de Compromiso).

✓The economic offer is scored via a three‑segment polygonal formula that distributes 0–100 points across all possible prices, ensuring the lowest price gets the highest score but avoiding excessive advantage for abnormally low (temerarias) bids, thereby discouraging destabilizing underpricing while still rewarding reasonable discounts around the market average.

✓The qualitative phase has an internal maximum of 100 points, with sub‑weights (e.g. 16 points for Memoria, 16 for Programa, 8 for Cartas), then normalized to 40 points overall.

✓There is an exclusion threshold: bids that score less than 50 points in the qualitative phase are rejected and their economic envelopes are not opened.

✓The requirement to submit a detailed construction method, work programme with critical path analysis, and binding commitment letters from key suppliers and subcontractors is justified as a way to assess the realism, coherence and risk control of each offer.

✓Such as the risks and special conditions, the documents underline several obligations that are deemed “esenciales del contrato” whose breach may lead to termination, including adherence to the sectoral collective agreement (“Convenio Colectivo del Sector de la Construcción de Melilla”) for all workers, including subcontracted staff, and the effective assignment of the jefe de obra residing permanently in Melilla and able to attend site within two working hours.

✓The jefe de obra is the sole interlocutor with the Administration, responsible for technical, economic, administrative management, safety and health (PSS), environmental, social and labour compliance (in line with LCSP and EU law), subcontracting rules (arts. 215–216 LCSP), payments to subcontractors, and internal quality control via a plan de calidad.

✓Subcontracting is permitted following PCAP clause 17; the tender highlights the need to manage island‑specific logistics risks by requiring letters of commitment for supplies, machinery, rentals and labour, especially when subcontracts are foreseen.

✓The validity period of offers is two months.

❓No explicit question deadline or site visit obligation appears in the extracted text, but general DEUC clauses address exclusion risks (criminal offences, tax/social security debts, breaches of environmental/social/labour obligations, professional misconduct, rescissions and sanctions, false declarations).

✓Such as possible contradictions or clarifications, the texts consistently state that the contract is not divided into lots, even though some solvency clauses refer to the hypothetical case of division into lots; here the applicable statement is the explicit “NO DIVISIÓN EN LOTES”.

✓There is also clarification that the classification requirement applies because the estimated value is above 500,000 €; references to alternative solvency routes for values below 500,000 € are purely hypothetical and non‑applicable in this specific tender.

✓Another apparent tension concerns territorial “arraigo”: although doctrine is generally critical of territorial residence conditions, the tender justifies and frames the residence of the jefe de obra in Melilla as a medium of contract execution under art. 76.2 LCSP, only demanded of the proposed awardee, and thus presented as compatible with principles of equality, proportionality and non‑discrimination.
