What is the VOB?
The VOB (Vergabe- und Vertragsordnung für Bauleistungen) is Germany's central regulatory framework for public construction contracts. It consists of three parts covering procurement procedures, contract conditions, and technical specifications.
VOB/A – Procurement Rules
VOB/A governs the award procedure for construction works, covering both national (below EU thresholds) and EU-wide procurements. It defines procedure types, deadlines, evaluation rules, and award criteria.
VOB/B – Contract Conditions
VOB/B regulates the contractual execution of construction contracts including execution deadlines, acceptance of works, defect claims with a 4-year warranty period, remuneration, and supplementary claims.
VOB/C – Technical Specifications
VOB/C contains over 60 individual DIN standards for specific trades (masonry, concrete, roofing, etc.), providing detailed technical requirements for construction work.
Importance for Construction Companies
The VOB is essential for construction companies as virtually all public construction contracts are awarded and executed under VOB rules. Knowledge of all three parts is a prerequisite for successful participation in public construction tenders.
