this call for tenders concerns the procurement of works for the replacement of roofs of shared buildings in Navantia San Fernando

❓While precise quantities (such as square meters of roof, number of buildings, material specifications) are not detailed in the excerpt, they are to be found in the technical specifications (PPT).

✓The place of performance is Puerto Real (Astillero Puerto Real, Polígono Astillero s/n, 11519 Puerto Real, Cádiz), and the execution period is clearly fixed at 6 months starting 16 November 2026.

✓The contract allows electronic invoicing (“Se aceptará factura electrónica: Sí”), does not use electronic ordering or payment, and is not co-financed by EU funds.

✓On award criteria and weighting, the summary mentions that the “Condiciones de adjudicación” rely on criteria “evaluables mediante un juicio de valor SEGUN PCP Y ETC/PPT : Otros Subtipo Criterio : 100 Ponderación.” This means that the evaluation will be based on qualitative/subjective criteria defined in the PCP/PPT (such as technical quality, methodology, planning, safety measures) with an overall weighting of 100 points, but the detailed breakdown (e.g. price vs technical quality) is not specified in this text.

✓There is no electronic auction (“Subasta electrónica: No”), and the opening of economic offers is an internal, non-public act, scheduled for 03/11/2026 at 08:32.

✓The offer submission deadline is 03/11/2026 at 10:00, and the deadline to submit requests to participate and obtain the tender documents is 19/10/2026 at 10:00.

✓On risks and special conditions, the text explicitly notes that subcontracting is permitted (“Subcontratación permitida”).

❓Such as in many Spanish tenders, bidders must ensure ongoing compliance with tax and social security obligations throughout contract performance.

❓No site visit, question deadline beyond the general “Plazo de Obtención de Pliegos,” or special guarantee amounts are described in the excerpt, so they must be checked in the full pliegos or via the indicated contact email addresses ([email protected] and [email protected]).

✓Regarding contradictions or corrections between documents, the provided text essentially repeats the same information from two related documents (01‑placsp‑4 and 02‑placsp‑7) corresponding to the announcement of tender and the pliegos notice.

✓The dates, amounts, procedure type, deadlines, and basic conditions are consistent between them (for example, both mention 715,715 EUR budget, 591,500 EUR estimated value, a 6‑month period from 16/11/2026, negotiated procedure with publicity, no electronic auction, subcontracting allowed).

Answers on the required criteria

Must securities be provided (bid bond, performance or warranty guarantee)? If so: which, in what amount and by when?

❓Regarding securities (bid bond, performance or warranty guarantees), the excerpt only mentions general participation requirements (capacity to contract, no prohibition to contract, compliance with tax and social security obligations, and foreign firms’ submission to Spanish law).

❓It does not state whether any bid guarantee, performance bond, or warranty guarantee is required, nor their amounts or deadlines.

✓These aspects are indicated generically as “SEGUN PCP Y ETC,” meaning they are regulated in the administrative clauses and other tender documents (PCP/Pliego).

❓Therefore, based solely on the provided text, it cannot be confirmed if securities are required; you must consult the PCP/Pliego via the tender detail link on the Plataforma de Contratación.

Is subcontracting allowed? If so: with which limits and which disclosure duties?

✓On subcontracting, the text explicitly states “Subcontratación permitida” (subcontracting permitted).

❓No limits, percentage caps, or specific disclosure/approval duties for subcontractors are set out in the excerpt.

❓Any detailed rules (such as maximum subcontracted share, mandatory identification of critical subcontractors, or prior authorization by Navantia) would be contained in the PCP/Pliego or technical specifications (PPT/ETC), which are only referenced, not reproduced here.

✓As such, all that can be concluded from this text is that subcontracting is allowed in principle, subject to the detailed conditions in the full tender documents.

Is there a site visit, and is attendance mandatory? If so: when?

❓There is no mention of any site visit (“visita a las instalaciones”, “visita obligatoria”, etc.), nor of whether it is mandatory or when it would occur.

In which language must the tender and the supporting documents be submitted, and are documents in other languages accepted?

❓Likewise, there is no explicit statement about the language of submission, although, in Spanish public procurement, Spanish is normally required; however, that requirement is not spelled out in the excerpt.
