Sanitärinstallation – Umbau und Erweiterung WC-Anlagen Stadtbibliothek Hannover (Vergabenummer 19-1041-26)
The input text concerns a public construction tender in Germany (Landeshauptstadt Hannover, Fachbereich Gebäudemanagement) for sanitary installation works in the Stadtbibliothek Hildesheimer Straße, including a related maintenance (Wartungs-) contract.
It is set within the framework of German public procurement law for construction (VOB/A, VOB/B) and the Niedersächsisches Tariftreue- und Vergabegesetz (NTVerG).
The electronic tender is run via the RIB Tender / meinauftrag.rib.de platform.
Only Germany is referenced, and the point of view is that of a German public contracting authority and German procurement rules.
In terms of what the bidder must submit and minimum qualification, the input text specifies several required form sheets and declarations.
Additionally, on separate request (Formblatt 216, Punkt 2) bidders must be able to furnish references (Referenznachweise), workforce statistics for the last three years, company registration documents (Gewerbeanmeldung, Handelsregister, Handwerkskarte/IHK), BG/Sozialkasse and Finanzamt tax clearance certificates, Freistellungsbescheinigung nach § 48b EStG, and product data sheets of offered brands.
The minimum qualification requirements follow VOB/A: either proof via Präqualifikationsverzeichnis (PQ-Nummer) or via Eigenerklärung zur Eignung with subsequent substantiation by certificates if the offer comes into closer consideration, including equivalent evidence for any Nachunternehmer.
Regarding the scope of the contract – what, how much, where, when – the Bekanntmachung Öffentliche Ausschreibung (Formblatt 121) and the LV describe the construction work as a “Sanitärinstallation” for the “Umbau und Erweiterung WC-Anlagen Stadtbibliothek Hildesheimer Straße” in Hannover, Germany.
The quantities include, such as, approx. 140 m PE drainage pipes DN56–DN125, approx. 130 m copper drinking water pipes DN12–DN31, approx. 140 m insulation, 11 washbasin units, 12 WC units, 5 urinals, 12 fittings, and the dismantling of existing TW and drainage pipelines including approx. 10 m asbestos drainage.
On award criteria and weighting, the documents clarify that the Zuschlagskriterium is primarily the price.
As stated, such as in Formblatt 211 and in the Bekanntmachung (121), the “Zuschlagskriterium Preis” is used, with the Wertungssumme calculated from the checked offer sum including unconditional discounts, any Erstattungsbeträge from a Lohngleitklausel, and offered maintenance services.

The Zuschlagskriterien are formally referenced via Formblatt 227, but in the excerpt the only criterion specifically named is price; there is no multi-criteria weighting table shown beyond that reference.
A special rule applies for workshops for disabled persons: these receive a 15% bonus in the economic evaluation; in case of equal economic performance compared to another bidder, the award goes to the workshop offer, provided its status is proven with the offer.
The documents also highlight risks and special conditions.
Security (Sicherheitsleistung) for contract performance and defects is normally waived but becomes mandatory: for contract performance, 5% of the gross contract sum (without change orders) is required if the net contract sum is at least €250,000; for defects, security equals 3% of the sum of installment payments at acceptance.
If security is provided by guarantee, prescribed forms (Vertragserfüllungsbürgschaft, Mängelansprüchebürgschaft, Abschlags-/Vorauszahlungsbürgschaft) must be used.
Further special conditions include a four-year limitation period for defects, mandatory compliance with working safety and health regulations, prohibition of smoking on the premises, 10 km/h speed limit on the client’s site, and immediate information duty in case of personal or property damage.
The contractor must attend site meetings every 14 days and, if required (unless the alternative text “kein Baufristenplan erforderlich” is chosen), prepare and update a construction schedule.
As for subcontracting, only technically competent, reliable Nachunternehmer may be used; their scope and identity (name, address, BG with member number) must be notified in writing, and they may not re-subcontract without written client consent.
The validity period of offers is governed by the Bindefrist (e.g. until 20.11.2026); questions/unclarities must be reported “unverzüglich” before bid submission under the Teilnahmebedingungen.
A compulsory site visit is not expressly mentioned in the provided excerpts.
Concerning contradictions or corrections, the documents set a clear hierarchy: the Besondere Vertragsbedingungen state a “Vorrang der Vertragsbedingungen des Auftraggebers”, meaning that the client’s contract documents always take precedence over any bidder’s conditions; the contractor’s own delivery or payment terms do not become part of the contract.
Within the tender documentation, where conflicting or alternative texts appear, the filled-in/checked options in the official forms apply; for instance, in Formblatt 214, the printed alternative “Auf Sicherheit wird verzichtet” is overridden by the conditional rule that security is required from €250,000 upwards, so the operative statement is: no security below that threshold, mandatory security above it.
Likewise, Formblatt 211 regulates Nebenangebote by selectable options; the specific project text says Nebenangebote are not allowed (6.1) so the general Nebenangebot rules in the Teilnahmebedingungen (Nr. 4) are explicitly declared inapplicable.
