What is UAV Conditions?
Updated: 11 March 2026
The Uniform Administrative Conditions for the execution of works (UAV 2012) are a set of standard conditions for construction contracts in the Netherlands, established by the Board of Arbitration for the Building Industry. The UAV govern the relationship between client and contractor during the execution of works, including liability, handover, variation orders, timelines, and dispute resolution. They are not automatically applicable by law but are made applicable by reference in the contract.
How does uav conditions work?
The UAV 2012 succeeded the UAV 1989 and are widely used across the Dutch construction and infrastructure sectors. They are not legislation but a set of model conditions that parties incorporate by contractual reference. Alongside the UAV 2012, the UAV-GC 2005 (Integrated Contract Forms) exist for design and build contracts where the contractor is also responsible for the design.
The UAV 2012 regulate, among other things: the contractor's obligations (paragraphs 5 and 6), project supervision by or on behalf of the client (paragraph 3), variation orders (paragraphs 35 and 36), construction time and penalties for overrun (paragraphs 42 and 43), handover and maintenance period (paragraphs 9 and 10), liability after handover (paragraph 12), and dispute resolution via the Board of Arbitration for the Building Industry (paragraph 49).
A key feature of the UAV is the distinction between hidden and visible defects. After handover, the contractor is released from liability for visible defects not recorded in the handover protocol. For hidden defects, a liability period of five years after handover applies (ten years for structural defects).
The UAV are not mandatory law: parties can deviate from them in the specifications or the construction contract. Pay close attention to which paragraphs are excluded or amended, this happens regularly and can significantly shift the risk allocation.
For subcontractors, note that when the main contract incorporates the UAV, they are often also applied to the subcontract via a back-to-back arrangement.
Why does this matter for SMBs?
The UAV 2012 provide a balanced risk allocation that is widely accepted in the construction industry. By incorporating the UAV, you avoid having to individually negotiate every contractual provision, you start with a standardised framework.
The risk lies in deviations. Clients who exclude or amend UAV paragraphs in the specifications shift risks to the contractor. Without reading the UAV text alongside the specifications, you may accept conditions that are significantly less favourable than the standard framework.
How to manage this correctly
- 1Check for every construction contract whether the UAV 2012 or UAV-GC 2005 have been incorporated and which version applies
- 2Read the UAV text alongside the specifications and identify every deviation from the standard provisions
- 3Pay particular attention to deviations in the paragraphs on liability, handover, and variation orders
- 4Record the maintenance period and liability period per project in your contract management system
- 5Apply the same UAV version to subcontracts as in the main contract (back-to-back)
