S-Red - Reparación del puente FG sobre DB en Zuettlingerstrasse

Such as with respect to the scope of the contract, the documents clearly define what, where and when: the works concern the “Instandsetzung FG‑Steg über DB bei der Züttlinger Straße” (rehabilitation of a steel footbridge over the Deutsche Bahn line in Stuttgart‑Rot), project number U23492130510. Examples in the price‑breakdown form (223) show typical work items and indicative quantities: sweep‑blasting steel surfaces to Sa 2 / Sa 2½, intermediate and deck coatings (PUR‑Deckbeschichtung Br. 100), steel de‑rusting, elastomer bearings and movable hold‑down constructions, concrete foundations C16/20, stainless steel wire‑mesh infill (Edelstahl-Drahtnetz 50×50 mm), large‑capacity crane (>350–400 t), protective tent (>100–300 m², h>4.5 m), and comprehensive site security for the whole project. The place of performance is Stuttgart, with defined logistics and storage areas around plot 3853/14 and a Baustelleneinrichtungsplan describing approx. 55 m × 12 m of free space and dedicated access routes; no living trailers or barracks are allowed in the construction area. The time frame is set in the Besondere Vertragsbedingungen (Form 214): start of works with a “Startgespräch” on 18.01.2027; latest registration of the railway closure and crane with Deutsche Bahn on 22.01.2027; latest submission of workshop drawings by 01.03.2027; and completion/abnahmereife Fertigstellung by 10.12.2027. These key dates are defined as Vertragsfristen under § 5 VOB/B and linked to contractual penalties. The SiGeKo coordination is required and largely assigned to the contractor (AN), who must name the coordinator before work begins if only his own staff and subcontractors are on site, whereas special clauses also foresee an AG‑appointed coordinator where multiple contractors are present.

Such as regarding award criteria and weighting, Form 211 (Section 7) explicitly states that the Zuschlagskriterium is primarily the “Preis”: the price is evaluated via the Wertungssumme derived from the corrected offer sum, taking into account unconditional discounts, any offered Lohngleitklausel‑Erstattungsbeträge (Form 224), and prices for Instandhaltungsleistungen. If several criteria are used, they are set in Formblatt 227 (not quoted here in detail); otherwise, price alone governs. There is a specific social policy bonus: offers from recognised “Werkstätten für Behinderte” receive a 15 % bonus on the Wertungssumme, and where such an offer is equally economical to another, the award goes to the workshop. Discounts are considered only if they are unconditional, stated as a percentage on the Abrechnungssumme, and entered at the designated place in the Angebotsschreiben (213). Nachlässe entered in the GAEB file on positions or titles are automatically integrated into the offer sum, not separately listed at opening. Nebenangebote may either be prohibited (211, section 6.1) or allowed under conditions (6.2); the general Teilnahmebedingungen (212, section 4) require that side offers meet minimum requirements, be qualitatively and quantitatively equivalent, fully describe all affected LV positions including quantities and unit prices, and provide proof of equivalence with submission; otherwise they are excluded. The tender also allows several Hauptangebote per bidder, provided each is fully self‑contained and non‑abusive, and recommends immediate explanation of price or technical differences.

Such as concerning risks and special conditions, the text sets out a series of contractual obligations and potential sanctions. Contractual penalties (Vertragsstrafen) are stipulated in Form 214: for each working day of delay against any contractual milestone (Einzelfrist) or the final completion date, a penalty per day or a percentage of the (sub‑)final account sum is payable, capped at 5 % of the Schlussabrechnungssumme (excl. VAT) for the entire contract, with special rules for partial deadlines. The Angebotsschreiben (213) contains a commitment to pay a lump‑sum damages of 15 % of the gross contract sum if the bidder has, in connection with the award, demonstrably engaged in anti‑competitive collusive behaviour, save where the bidder proves a lower damage. Security provisions in the Besondere Vertragsbedingungen require, where the net contract sum is at least 250,000 €, a security for performance of 5 % of the (gross, excluding change orders) contract sum and a security for defects of 3 % of the sum of progress payments at acceptance; these can be provided via standardised VHB Bürgschaftsformblätter 421 (Vertragserfüllungsbürgschaft), 422 (Mängelansprüchebürgschaft) and 423 (Abzahlungs-/Vorauszahlungsbürgschaft) if any agreed advance payments are made. No advance payments are granted unless explicitly agreed in the WBVB, in which case they require a 423‑type guarantee and are repaid through retention from subsequent payments. The tender also mandates tariftreue and minimum wage compliance under the Baden‑Württemberg LTMG via specific Verpflichtungserklärungen; violations can trigger contractual penalties up to 1 % of the contract value per breach (5 % maximum), exclusion from the current procedure, exclusion from future awards for up to three years, and even termination for cause. There are further risks in relation to competition law and public registers: exclusion of offers participating in unzulässige Wettbewerbsbeschränkungen; automatic requests for Gewerbezentralregister and Wettbewerbsregister extracts above defined thresholds; and mandatory notification obligations regarding changes to Freistellungsbescheinigungen. On subcontracting, Form 233 and related guidance emphasise that subcontracted positions must be precisely tied to LV‑Ordnungszahlen, that vague descriptions are not allowed, that NU‑sums in price‑ermittlungsforms (221/222) must match those in Form 233/235, and that NU‑firms must also meet PQ or Eigenerklärung requirements. The validity period (Bindefrist) is specified in Form 211, with the bidder in Form 213 confirming that their offer remains binding until its expiry. Questions on the tender must be submitted at least three working days before the end of the offer period, in text form via email or the RIB e‑Vergabeplattform; all clarifications are distributed to all bidders.

Such as concerning contradictions or corrections, the documents contain internal cross‑references clarifying which statement prevails where differences arise. The Teilnahmebedingungen (212) state that where bidders consider any part of the tender documents unclear, incomplete or incorrect, they must immediately notify the contracting authority prior to bid submission; clarifications and amendments issued by the authority become binding and are explicitly recognised in the Angebotsschreiben (213, clause 8) as part of the offer. The same clause establishes that only the AG’s “Langfassung des Leistungsverzeichnisses” is binding if there is a mismatch with any contractor‑prepared abbreviations or excerpts, and that “oder gleichwertig” product specifications fall back to the AG’s proposed product where the bidder fails to name an alternative. The Besondere Vertragsbedingungen (214, clause 7) specify that all referenced technical specifications are to be treated as including “gleichwertige” alternatives even without explicit wording, reducing ambiguity in norm references. With Nebenangebote, the apparent contradiction between 211 (which allows the authority to choose whether they are permitted) and 212 (which details general rules for side offers) is resolved by 211 section 6.1: if Nebenangebote are marked as “nicht zugelassen”, the general side‑offer rules in 212 section 4 do not apply (“Nummer 4 der Teilnahmebedingungen gilt nicht”); if they are permitted, the rules in 212 section 4 control their form and evaluation. Where there is variance between generic VHB text and project‑specific WBVB or ETV‑Stadt (e.g. on SiGeKo responsibilities, logistics areas, waste management), the project‑specific clauses (WBVB 120 ff., ETB/ETV‑Stadt) prevail as “Weitere Besondere Vertragsbedingungen” and are explicitly made contract components in 211, section B). As a general rule, any individual project modifications or additions stated in the Besondere Vertragsbedingungen, Weitere Besondere Vertragsbedingungen and the Leistungsverzeichnis override generic guidance, and bidders are cautioned not to try to “correct” these by cover letters, as such changes may be treated as unzulässige Änderungen der Vergabeunterlagen and lead to exclusion under § 16 VOB/A.
