Halde Hoheward, Horizontal Observatory, Herten - Renovation - Civil engineering and paving...

✓Award criteria and weighting are described succinctly: the Zuschlagskriterium is “Preis”, with the award based on the Wertungssumme derived from the recalculated offer sum, including such as discounts, refunds from the Lohngleitklausel, and any maintenance (Instandhaltungs-) offers.

✓The documents also mention “Mehrere Zuschlagskriterien gemäß Formblatt Zuschlagskriterien” insofar as a special rule applies for Werkstätten für Behinderte: these receive a 15% bonus on the Wertungssumme and, if equally economical as another offer, must be preferred.

✓Proof of status as a workshop for disabled persons must accompany the offer.

❓No qualitative criteria (e.g. concept, methodology) are mentioned in the provided text; thus the procedure is essentially price-driven with a specific social policy adjustment.

✓Risks and special conditions are addressed extensively in the general conditions and the geotechnical report.

✓Contractual and procedural risks include, such as: Nachträge due to ignorance of the geotechnical report or local conditions are “ausgeschlossen”; bidders thus bear the risk of properly understanding the soil data (Homogenbereiche, Bergematerial characteristics, frost susceptibility, environmental constraints) when pricing.

✓Subcontracting is allowed but controlled via the Verzeichnis der Nachunternehmerleistungen and the Verpflichtungserklärung anderer Unternehmen.

✓The binding period (Bindefrist) runs to 30.11.2026.

❓Penalties and guarantees are not explicitly quoted in the excerpt but standard VOB/B rules apply; detailed penalty/guarantee clauses likely appear in the “Vertrag Tiefbau- und Pflasterarbeiten” referenced as a contract attachment.

✓Special technical and environmental risks include the windexposed, slope-adjacent location, restricted heavy-load areas, public recreational use of access roads, and the need to protect the “Sternentheater” and other objects.

✓The geotechnical report describes the halde’s layered fill (non-cohesive topping, Bergematerial, no groundwater up to 20 m), abrasiveness, potential contamination issues (MP 2 TOC > BM-F3 under EBV, requiring particular disposal or supervised reuse), and the recommendation to map soil to Homogenbereiche for clear contract pricing.

✓Kampfmittelbeseitigung is addressed: no prior checks are required, but suspicious findings must halt work and trigger engagement of the Kampfmittelräumdienst.

✓Bergbauliche Einflüsse are deemed irrelevant by RAG.

✓Advertising on site is allowed only with prior approval of the AG.

✓The documents define strict acceptance procedures (Leistungsabnahme) for foundation soles, Hilfsfundamente, buried lines, Corten edging, and reinstated paving, with at least five working days’ notice and comprehensive documentation (Lieferscheine, Aufmaß) per VOB/B §14; these constitute operational and payment risks if not complied with.

❓Regarding contradictions or corrections, the excerpts themselves do not reveal overt conflicting statements.

❓Where potentially overlapping provisions occur, the hierarchy can be inferred from typical German practice: the “Aufforderung zur Abgabe eines Angebotes” and Bewerbungs-/Vergabebedingungen govern procurement rules (e.g. what can be nachgefordert, what must be submitted with the tender); the “Allgemeine Bedingungen und Vorbemerkungen zum LV Tiefbau- und Pflasterarbeiten” and the LV itself govern technical scope and performance obligations; and the geotechnical report (Anlage 1) provides the binding basis for ground conditions, with explicit statements such as “Nachträge durch Unkenntnis über das Bodengutachten … ausgeschlossen” indicating its precedence over bidders’ assumptions.

✓Where the geotechnical report notes that in-situ deviations and hidden obstructions cannot be excluded and must be dealt with via special accounting arrangements, this is not a contradiction but a qualification: bidders must price based on the report while accepting that exceptional conditions (e.g. unforeseen Bauwerksreste) will be handled separately.

❓No explicit question deadline or mandatory site visit is quoted in the provided text; given the reference to electronic communication via the Vergabeplattform, questions would typically be handled through that platform under the general Bewerbungs- und Vergabebedingungen, which should be consulted for any specific clarification procedures.
