DGZ Graustein - Lot 17 - Interior doors

✓The time frame is regulated in the Besondere Vertragsbedingungen (Formblatt 214) and a separate Bauzeitenplan: the start date is tied either to a fixed calendar week or to a number of working days after receipt of the award letter, and completion must be achieved by a specified contractual deadline; these start and completion dates are explicitly declared as “Vertragsfristen”.

✓The binding period for offers runs until 10.12.2026, while offers must be submitted electronically by 11.11.2026, 10:00, via the Vergabemarktplatz Brandenburg; late or wrongly transmitted offers (e‑mail, fax, communication area) are mandatorily excluded.

✓Award criteria and their weighting are comparatively simple and mainly price‑driven.

✓Such as: the Aufforderung zur Angebotsabgabe states “Zuschlagskriterium Preis”, with the award price derived from the “Wertungssumme” of the offer, including recalculated offer sum, unconditional discounts, and – if relevant – effects of a Lohngleitklausel and any linked Instandhaltungsangebote.

✓Nebenangebote (variants) are as a rule not allowed in this procedure (explicitly: “Nebenangebote sind nicht zugelassen, Nummer 4 der Teilnahmebedingungen gilt nicht”), and any variant or modification of the tender specifications, including attaching own general terms and conditions (AGB), is defined as an inadmissible change of tender documents and leads to exclusion.

✓Price discounts are only evaluated if unconditional and indicated at the specific location in the Angebotsschreiben.

✓The documents contain numerous risk‑related and special conditions, such as contractual penalties, guarantees, subcontracting rules, minimum‑wage enforcement and data/communication obligations.

✓For example, the Besondere Vertragsbedingungen (214) allow the Auftraggeber to impose a daily contractual penalty for each day of delay in meeting the contractual start, completion, or specific intermediate deadlines, capped at a defined percentage of the net contract sum.

✓Security for contract performance is required at 5 % of the contract sum (incl. VAT, without change orders) where the net amount is at least 250,000 EUR; security for defects claims is set at 3 % of the sum of interim payments at acceptance; these securities must be provided, if used, via the client’s standard guarantee forms.

❓The Brandenburg minimum‑wage agreements (VHB‑Bbg 5.4 EU) impose a strict duty to pay at least the BbgVergG minimum hourly wage (13,00 EUR, but at least federal MiLoG 13,90 EUR from 01.01.2026) to all workers involved and to ensure equivalent commitments from all subcontractors and labour leasing firms; breaches trigger contractual penalties of 1 % of contract value per proven case (max. 25,000 EUR, total max. 5 % / 250,000 EUR) and can lead to up to three‑year exclusion via a central blocking list, with the possibility of “Selbstreinigung”.

✓Additionally, the Angebotsschreiben includes a clause on a 15 % lump‑sum damage payment if the bidder is proven to have participated in unlawful collusion, unless a lower damage is proven.

✓Subcontracting is regulated in VVB 233 (Verzeichnis der Nachunternehmerleistungen) and VVB 235/236, requiring early declaration of subcontracted scopes, naming of subcontractors (names requested already at offer stage) and, in case of capacity loans, binding commitment declarations with joint liability.

✓Special BVB clauses stipulate extended working hours (up to 22:00 on weekdays, Saturday work), mandatory weekly site meetings and site diaries, daily cleanliness, procedures for time‑and‑materials work and change orders, and detailed waste‑management obligations including proof of proper disposal and possible naming of disposal facilities.

✓As for contradictions or needed corrections, the documents themselves clarify the primacy and binding nature of certain statements.

✓Such as: the Teilnahmebedingungen and the Hinweisblatt emphasise that only the officially provided long‑form Leistungsverzeichnis is binding; self‑created short versions serve solely as working aids.

✓The Aufforderung zur Angebotsabgabe and the Hinweise zur Angebotsabgabe stress that any change or supplement to the tender documents – including the unintentional inclusion of the bidder’s own AGB on stationery, catalogues etc. – constitutes an inadmissible change and leads to automatic exclusion; simultaneously, the same Aufforderung reiterates that “es gelten ausschließlich die Vertragsbedingungen des Auftraggebers (inklusive Vergabeunterlagen, BVB, ZVB)”.

✓Where there appears to be an older standard text referring to written submission (213/211 general text) versus the specific project note that “Schriftliche Angebote sind nicht zugelassen”, the project‑specific marking in the Aufforderung (Zulassung ausschließlich elektronischer Angebotsabgabe über das Bietertool) governs.

✓Likewise, if there is any perceived inconsistency between GAEB data exchange files and the written tender, VVB 244 clarifies that the written version prevails and differences must be marked by the contractor.

✓In case of any remaining uncertainty, bidders are obliged to submit clarification questions exclusively via the Vergabemarktplatz Brandenburg within the stated period; they must not self‑correct texts, leave fields blank, or alter wording on their own, as such modifications would render the offer inadmissible.
