TWL Eichwerder oriental

The scope of the contract is defined as the renewal of the drinking water network (TWL and house connections TWL‑HA) in the area Östliches Eichwerder, including streets such as Detlef‑von‑Liliencron‑Straße and Freiligrathstraße. Such as: the LV sets out detailed quantities for excavation, pipe laying, house connections, surface reinstatement (paving, topsoil, seeding per DIN 18917, signage per DIN 4067), and documentation. Execution is scheduled between 05.04.2027 (start) and 15.12.2028 (end), with the bid submission deadline at 10.12.2026, 10:00 (digital via Vergabemarktplatz). The place of performance is 16321 Bernau bei Berlin; the construction site setup areas must be obtained by the contractor in coordination with landowners and then restored. The scope includes, for example, complete site installation and clearance, traffic management and safety according to StVO/RSA 21 (including multiple traffic orders, traffic sign plans, temporary signs, construction fence and trench safety), coordination of Vermessung (survey by a firm appointed by the client), creation of an extensive drinking water documentation (on USB stick) per WAV “Panke/Finow” guidelines, and coordination of house connection switchovers with property owners. All materials must comply with DVGW and DIN EN standards; only approved materials for the given medium (water), pressure class and dimensions may be used.

Award criteria and weighting are only indirectly mentioned. Such as: the tender is an “Öffentliche Ausschreibung” and the “Teilnahme am Wertungsverfahren” requires punctual submission and fully completed documents; only “vollständige Angebotsabgaben” will be evaluated. No explicit scoring matrix (price, quality, etc.) or weighting is specified in the cited text, and no stated Zuschlagsfrist or formal validity period of offers appears (Zuschlagsfrist is listed as “k.A.”). Standard VHB forms 221/222 for price calculation (Zuschlagskalkulation vs. Endsummenkalkulation) are annexed, showing the expected structure of cost breakdown (Einzelkosten, Baustellengemeinkosten, Allgemeine Geschäftskosten, Wagnis und Gewinn), but they do not state evaluation weights—rather they structure how the bidder should calculate and, on request, explain prices (including for subcontractors). In practice, this suggests price will be a major criterion, combined with formal and technical suitability, but explicit award weighting is not given in the provided excerpts.

Risks and special conditions for bidders are set out in several places. Such as: there is no separate remuneration for many coordination and logistics tasks (e.g. coordination of house connection appointments, coordination with Barnimer Dienstleistungsgesellschaft for waste container logistics, site documentation, participation in site meetings, traffic control checks), which must be priced into unit rates. Winter construction risks are shifted to the contractor, as “zusätzliche Vergütungen für die Ausführung der Arbeiten im Frostbetrieb sollten nicht erfolgen”; if necessary, work must be stopped, secured and monitored without extra payment. The contractor bears responsibility for all utilities in the construction area and must obtain utility location information and notify operators before work; damage risk is thus significant. The contractor becomes Abfallerzeuger and -besitzer and assumes all obligations for waste management under KrWG and the Nachweisverordnung, including separate collection, proper disposal, and submission of disposal proofs (form 241 and Baubeschreibung section 4.17). Construction water and electricity must be procured and paid by the contractor (costs included in unit prices). Guarantees and penalties are minimally specified in the LV front page: “Sicherheit / Gewährleistung: 0,00% vom Rechnungsbetrag”, and “Vertragsstrafe: -” (blank), which indicates that no separate security retention and no explicitly defined contractual penalty are set in this section; however, standard VOB/B rules may still apply via the “Allgemeinen, Zusätzlichen, Technischen und Besonderen Vertragsbedingungen” referenced. Subcontracting is allowed but tightly controlled: subcontractors’ services must be listed in form 233, names must be provided already at offer stage, and the client can demand detailed calculations from subcontractors. The client explicitly prohibits “Fremdüberwachung” as a substitute for missing or expired DVGW certifications; the bidder must itself hold the required approvals. Site inspection is strongly recommended (“Dem Bieter wird ausdrücklich empfohlen, das Baufeld im Vorfeld zu besichtigen”), which implies that bidders carry the risk of unforeseen conditions if they fail to inspect.

Regarding contradictions or corrections within the documents, the excerpts largely show consistent requirements, and some duplication rather than conflict. Such as: both the Baubeschreibung (sections 4.7, 4.8, 4.17–4.23, 5.1–5.3) and the LV “Allgemeine Hinweise zur Gesamtbaumaßnahme” state that all contents of the Baubeschreibung are to be included in unit prices and become part of the contract—this is consistent. Waste obligations in Baubeschreibung 4.17 match those in form 241. The LV front page lists “Sicherheit / Gewährleistung: 0,00% vom Rechnungsbetrag”, which is not contradicted elsewhere in the provided text. A potential apparent tension is that the LV states “Nebenangebote … sind nicht zugelassen”, while form 241 allows “eine andere als die in der Leistungsbeschreibung genannte Lösung” for waste treatment—however, form 241 treats such alternative disposal pathways as part of the main offer (subject to proof), not as formal “Nebenangebote” to the construction method, so the construction method itself remains fixed. Overall, where statements overlap, the more specific provisions in the Baubeschreibung and technical LV text apply, and the tender explicitly says that the “in der Leistungsbeschreibung eingefügten Allgemeinen, Zusätzlichen, Technischen und Besonderen Vertragsbedingungen … werden Vertragsgrundlage”; bidders should therefore treat the Baubeschreibung + LV + VHB forms as jointly binding and include all described obligations in their prices.
