O 2026-161 GB Nature Conservation Monitoring - Biotopes and Vegetation

The scope of the contract is described as monitoring and documenting biotopes and vegetation in the Tegeler Stadtheide in the investigation years 2027 and 2029. Such as: flächendeckende biotope mapping of approx. 148 ha according to the current Berlin biotope key with additional attributes; recording dominance stands of three plant “problem species”; vegetation surveys on 45 permanent plots in two seasonal aspects (spring and summer), including digital data matrix entry and compilation of a complete species table; floristic survey of the entire investigation area with mapping of eight target species; creation of shapefiles with attribute tables for all biotope polygons; and preparation of annual written reports in Word/PDF. Place of performance is Berlin (postcode 13405, Tegeler Stadtheide). The contract period begins with award, runs until the end of the 2029 investigation year, with key performance deadlines of 30.11.2027 and 30.11.2029 for abnahmereife delivery. A kick‑off meeting on site (2 hours) and an online debrief meeting (4 hours) are included.

Award criteria and their weighting are straightforward. Such as: the only stated Zuschlagskriterium is the price – the offer with the lowest overall price (including all contract years and any optional services) receives the award, provided minimum suitability requirements are met. The Bekanntmachung (section 16) refers to “Zuschlagskriterien siehe Vergabeunterlagen” but is clarified in Teil A (Verfahrensbedingungen): section 9.1 explicitly states “Das einzige Zuschlagskriterium ist der Preis” and 12–13 repeat that the cheapest total price wins and that the bidder is bound until 31.12.2026. Technical and professional criteria serve only as Mindestkriterien zur Eignung (pass/fail) and not as weighted award criteria. No qualitative scoring is applied.

Risks and special conditions for bidders are set out mainly in the Verfahrensbedingungen and the draft Werkvertrag. Such as: the bidder must submit a complete, timely electronic offer via the iTWO/RIB Tender platform in German; late or formally non‑compliant offers are excluded and are not returned. Bid validity (Bindefrist) runs until 31.12.2026. The contracting authority reserves the right, but not the obligation, to request missing documents post‑submission; bidders are advised to submit complete offers. There are no securities (Sicherheitsleistungen) required; payment conditions follow Wirt‑215 (Besondere Vertragsbedingungen). The Werkvertrag includes an Anordnungsrecht of the client for changes/additional services under §§ 650b, 650c BGB and stipulates that all ancillary costs are covered by the agreed fee. Compliance risks arise from extensive exclusion‑ground declarations (criminal, tax, social security, minimum wage, Schwarzarbeit, Lieferkettengesetz) and the obligation to ensure that all deliverables are free from third‑party rights, including for subcontractors. Subcontracting is allowed but sensitive: the announcement requires that all main tasks be performed by the contractor or a consortium member, and any sub‑tasks must be declared via Wirt‑235; subcontractors and “Eignungsverleiher” are subject to the same exclusion checks and may require Wettbewerbsregister self‑declarations. Bietergespräche may be held in KW 47/2026 but cannot be used to negotiate or modify offer contents. Site visits are not mandated in the documents, beyond the necessary fieldwork once contracted. Insurance coverage and proof of social insurance/ tax registration can be made conditions for payment.

Regarding contradictions or corrections, the documents largely align, with some points needing interpretation. Such as: while the Bekanntmachung mentions various possible offer submission formats, it clearly restricts this procedure to “nur elektronische Angebote zugelassen – elektronisch in Textform”; this is confirmed in Teil A and IV 2121/Wirt 2121. Any mention of qualified signatures is generic and overridden by the specific statement that a qualified electronic signature is not required; scanned signed PDFs suffice where a signature is demanded. The announcement section 16 (“Zuschlagskriterien siehe Vergabeunterlagen”) could suggest multiple criteria, but the Verfahrensbedingungen state uniquely that price is the only award criterion; this specific rule in Teil A governs. The reference to “Qualitative Zuschlagskriterien” in the contents list is marked as “Fehler! Textmarke nicht definiert.” and is overridden by the explicit statement that there are no qualitative criteria. Bietergemeinschaften are told in the Bekanntmachung to submit a collectively signed Wirt‑238, whereas the form itself clarifies that in electronic procedures text‑form declarations from all members suffice initially; if in doubt, the more specific form instruction for e‑submission applies, with the authority able to require a fully signed version later. Where formulations in generic guidance (e.g. on signatur types or multiple award criteria) differ from the tender‑specific rules, the tender‑specific statements in Wirt‑121‑A, Teil A, Teil B and the Werkvertrag take precedence.
