Sint-jacobskerk: Consolidation of interior nave and choir

Such as indicated in I.1, II.6 and in the technical/restoration notes, the scope of the contract is clearly defined in terms of what, where, and when, with indicative quantities in the detailed meetstaat. The subject is “Sint‑Jacobskerk: consolidatie interieur schip en viering,” including consolidation of plaster layers and stabilisation of the oksaal (doksaal), works to masonry, timber structures, plasterwork, and decorative painting/restoration of historical finishes in the ship and crossing (viering). The place of performance is the Sint‑Jacobskerk in Leuven (Belgium), under the supervision of the city’s buildings directorate and the external architect Studio Roma. The meetcodes follow NBN B 06‑001:1982; quantities in the detailed meetstaat are indicative and the contractor must verify all dimensions and real quantities before tendering, and report any errors or gaps at the time of bidding. The execution period is set at 180 working days. The contract is an assignment with mixed price determination (gemengde prijsvaststelling) and includes both fixed and conditional sections: notably article 15.82 “Verwijderen van asbesthoudende beplating, hermetische zone – GP” is a conditional part only to be executed upon a later decision. The warranty period is 12 calendar months from provisional acceptance, with the contractor obliged to request both provisional and final acceptance himself.

Such as in I.10 and I.13, award criteria and weighting are straightforward: price is the sole awarding criterion. The contracting authority will choose the economically most advantageous tender determined on the basis of price only; no variants or free options are allowed, and there are no required or permitted variants/options. Although the offer structure mentions documents for the “beoordeling van de gunningscriteria,” in this case those criteria consist solely of price; qualitative elements serve for selection/access, not for award scoring. The binding period of the tender is 120 calendar days from the deadline for receipt of tenders. The procedure used is the “vereenvoudigde onderhandelingsprocedure met voorafgaande bekendmaking,” but the authority reserves the right to award on the basis of initial tenders without negotiations.

Such as detailed in II.2–II.5, II.8–II.15 and related clauses, the documents set out numerous risks and special contractual conditions for the contractor. Subcontracting is allowed, including reliance on subcontractors’ capacity at selection stage, but the main contractor remains fully liable and must use the pre‑proposed subcontractors when their capacity was relied upon. Any new subcontractors require prior approval and must meet equivalent qualitative requirements and not be in an exclusion situation. Under‑contractors must have appropriate Belgian recognition as contractors (erkenning) when their part exceeds legal thresholds; for this assignment the required recognition category/class is D23 (Restauratie door ambachtslieden), class 4, or D24 (Restauratie van monumenten), class 4. For parts to be subcontracted, the bidder must annex signed commitment letters from those subcontractors. Insurance conditions are strict: the contractor must take out and prove specific insurances for major repair, maintenance and renovation works, submit attestations at least 14 days before start and within 15 days of any request, and ensure subcontractors are similarly covered; the attestations must include a clause that any reduction or cancellation becomes effective only after 30 days’ notice to the client. A guarantee (borgtocht) of 5% of the original contract amount (excl. VAT), rounded up to the next 10 EUR, must be provided within 30 days after award, with release in two tranches at provisional and final acceptance; failure allows measures under art. 29 KB 14 januari 2013. There is a price revision formula based on labour and index parameters (k = 0.55*s/S + 0.25*i‑2021/I‑2021 + 0.20 applied to the full meetstaat). Payment term is extended to 60 calendar days due to project complexity and third‑party supervision. Additional risk provisions include: obligations regarding illegal third‑country workers (Sociaal Strafwetboek art. 49/2), liability for helper persons (hulppersonen) with waiver of direct tort claims against the client’s helpers except in cases of intent, fraud or bodily/psychological harm, and rules about the occupation of public domain (free parking in the work zone only for vehicles directly involved in the works, mandatory permits via Leuven police and Spotbooking; fines cannot be retroactively cancelled). Variants and options are excluded, and any tender that adds conditions making acceptance of the specifications unclear may be declared substantially irregular.

Such as clarified in the addendum “Vragen bij de aanbestedingsdocumenten” and cross‑references, the documents also address contradictions or corrections. A key contradiction in the original safety and health plan (V&G‑plan) was that page 12 stated that cost price calculations for special preventive measures were “not applicable,” while page 15 required cost price information for such measures. The addendum (dated 23‑10‑2026) corrects this: page 12 is amended so that cost calculations for special preventive measures are indeed required, and page 15’s example (accessibility of wood structure – use of lifelines on difficult positions) remains as a specific application whose cost must be priced. A second issue concerned the method for removing asbestos‑containing plates (menuiserite): the initial description assumed “eenvoudige handelingen,” but, because the plates will likely have to be broken (changing their condition) and inspectors would not accept this as simple handling, a new conditional article 15.82 was added to the technical specifications and meetstates for removal in a hermetic zone under global price, with conditions defined in that article. Correspondingly, section I.13 in the administrative provisions was expanded to mention that the authority is only bound by fixed sections and that article 15.82 is conditional. Regarding apparent duplication between the original administrative provisions (02‑20260911) and the “Aanpassing” document (11‑20261020), the latter functions as an updated version; blue text marks changes. Where there is divergence, the adjusted (Aanpassing) document, together with its addendum on questions, should be regarded as prevailing, since it explicitly states that changes have been incorporated into the tender documents.
