Versorgungskanal West, Tief- und Rohbauarbeiten (26-28348)

✓Such as specified in the Besondere Vertragsbedingungen (214), the execution period is fixed: start of works on 08.02.2027 and completion (abnahmereif) by 04.08.2028, and these dates are declared as Vertragsfristen.

✓Additional scheduling requirements include a Baufristenplan to be prepared and kept updated within 14 working days after award, coordinated with other trades.

✓The place of performance is clearly the university site in Stuttgart; water and energy costs during construction are borne by the client and must not be priced into unit rates.

✓On award criteria and weighting, the text states that the Zuschlagskriterium is primarily “Preis”, i.e. lowest economic price, with the Wertungssumme derived from recalculated offer sums, considering discounts, effects of the Lohngleitklausel and any Instandhaltungsangebote.

⚠Such as mentioned in the Aufforderung, there is also an attached “Anlage 227 Zuschlagskriterien” for any additional criteria and their weighting; however, the excerpt we have confirms that price is the decisive criterion.

✓A specific bonus rule applies for “Werkstätten für Behinderte”: these receive a 15% bonus on the Wertungssumme, and in cases of equal economic result, the award must go to such a workshop, provided its status is proven with the offer.

✓Regarding risks and special conditions, the Besondere Vertragsbedingungen introduce several contractual risk elements.

✓Such as outlined, there are contractual penalties (Vertragsstrafen) under § 11 VOB/B for each working day of delay in meeting the start and completion dates and any additional Einzelfristen; while the daily rate or percentage is left blank in the excerpt, the total is capped at 5% of the net contract sum.

✓Security for contract performance of 5% of the contract sum (including VAT, excluding change orders) is required if the contract amount is at least 250,000 EUR, plus a 3% security for defects based on the sum of interim payments at acceptance.

✓These securities, if provided as guarantees, must use the client’s standard Bürgschaft forms.

✓Subcontracting and Eignungsleihe are permitted but controlled: the bidder must list all subcontracted parts (233), capacities of other firms (235), and later produce Verpflichtungserklärungen (236), including joint liability when financial capacity is borrowed.

✓Safety-related declarations for Nachunternehmer may be requested via Formblatt 126.

✓The documents also impose obligations on waste management (241) including proof of authorized disposal routes, GAEB-based electronic data exchange (244), mandatory e‑invoicing via XRechnung and PTS use, weekly site meetings attendance, and IT-security incident reporting to SITiF BW.

✓The validity period of the bid is the Bindefrist until 11.01.2027.

✓Questions and clarifications must be raised “unverzüglich” before submission in text form per the Teilnahmebedingungen; there is no explicit site visit requirement mentioned in the provided text.

✓As to contradictions or corrections, the documents include internal rules determining which statements prevail.

✓Such as stated in 244 (Datenverarbeitung), in case of discrepancies between electronic GAEB data and the written version of tender or billing documents, the written version is binding; the GAEB files are considered working aids only unless exchanged via the Vergabeplattform in the context of the electronic procedure.

✓The Teilnahmebedingungen clarify that a self-made short version of the Leistungsverzeichnis is not binding; only the official long version applies.

✓No direct contradictions on key points like allowed Nebenangebote appear; where Teilnahmebedingungen generally explain Nebenangebote, Formblatt 211 explicitly states that “Nebenangebote sind nicht zugelassen”, and this specific statement applies, thereby disallowing alternative offers despite the general framework text.
