Supply of natural gas piped for heating in the centres under the Provincial Directorate of the National Institute of Social Security of Burgos, not subject to shared costs, for the period from 1 January to 31 December 2027.

✓Contract for the supply of natural gas to INSS Burgos centres (Expediente 09/UC-31/26)

✓The input text concerns a Spanish public procurement procedure launched by the Instituto Nacional de la Seguridad Social (INSS), Dirección Provincial de Burgos, for the supply of natural gas via pipeline for heating purposes.

✓It is firmly situated in the legal and administrative framework of Spain, repeatedly citing Spanish laws (LCSP, Ley 9/2017, Ley 34/1998) and Spanish public bodies and locations (Burgos, Ministerio de Inclusión, Seguridad Social y Migraciones).

✓The point of view is that of a Spanish contracting authority preparing, approving and publishing an open simplified tender.

✓Regarding what the bidder must submit and the minimum qualification requirements, the documents show that there is a single electronic envelope (“sobre único”) containing both administrative documentation and the automatically quantifiable criteria (the price offer).

✓The bidder must prove its capacity to contract and absence of prohibitions to contract in terms of the LCSP, and must hold the appropriate “título habilitante”: specifically, it must appear in the updated list of companies authorised to commercialise natural gas on the website of the Comisión Nacional de la Energía, in line with Real Decreto 197/2010 and RD 1434/2002.

❓There is no mention in the extracted text of explicit requirements for minimum turnover, specific insurance levels, or references beyond those legal-capacity and registration conditions, and no separate technical or economic scoring criteria are described that would require supporting forms or case references.

❓Concerning the scope of the contract (what, how much, where, when), the contract object is clearly defined several times as the “suministro de gas natural canalizado para calefacción” in INSS Burgos centres not subject to shared expenses, for the period 1 January 2027 to 31 December 2027.

✓The initiating order lists three specific centres (c/ Trinidad, Avda. del Vena, and Avda. de los Derechos Humanos, all in Burgos) as examples of the workplaces covered.

✓The estimated value of the contract is 46,282.79 EUR (VAT excluded), and the budget base for tendering is 56,002.17 EUR (including 21% VAT), with detailed annual allocations for 2027 and 2028 corresponding to the invoicing pattern.

✓The duration is set at 12 months, with no possibility of extension, no division into lots, and the contract must include both the acquisition of gas and access to networks, with the supplier handling the ATR network access, readings, reporting to the market operator, and mandatory verifications.

✓As for award criteria and their weighting, the procedure is an “procedimiento abierto simplificado abreviado” under article 159.6 LCSP, with a single award criterion: price.
