Mangelhafte Subunternehmer-Verifizierung – Haftungsrisiko & Rework

Definition

Search result [6] confirms: 'How can main contractors check whether their subcontractors are prequalified?' Answer: Query PQ number via PQ list search. However, manual search is slow, error-prone, and asynchronous: (1) Main contractor compiles subcontractor list; (2) Manually searches each sub on pq-verein.de; (3) Records PQ status (or discovers absence of prequalification); (4) Must halt bid preparation if sub is not prequalified or PQ is expired. For a typical mid-sized project (15–30 subcontractors across trades: Elektro, Lüftung, Heizung, Dach, Fassade), this manual check takes 5–10 hours. Errors occur when: (a) PQ expires between tender and contract execution; (b) Sub operates under multiple legal entities (GmbH variants) and contractor queries wrong registry entry; (c) Commodity group change not reflected in cached data. Result: Bid rejected by client; project lost. If error discovered post-award, contractor must engage new sub, renegotiate contract, absorb cost delta (typically 5–15% markup for emergency sourcing).
