What is the Building Quality Assurance Act?
The Building Quality Assurance Act (Wkb), effective January 1, 2024, as part of the Environment and Planning Act, reforms building supervision by transferring technical compliance checks from municipalities to independent quality guardians. They assess plans beforehand, execution during construction, and issue a compliance declaration upon completion.
Phased rollout: starts with new builds in consequence class 1 (simple structures like homes and small commercial buildings), later including renovations. Technical rules are in the Decree on Building Environment (Bbl), covering fire safety, foundations, and energy efficiency.
Why is the Building Quality Assurance Act important?
For construction firms and clients in tenders, the Wkb reduces failure costs via better assurance and transparency through a delivery dossier and expanded contractor liability. In public contracts, it ensures higher quality, fewer defects, and stronger buyer protection. Municipalities retain enforcement powers.
How does the Building Quality Assurance Act work?
1. Check via Environment Portal if project falls under Wkb.
2. Engage certified quality guardian.
3. Develop assurance plan with controls.
4. Submit building notification with plan, assurance plan, and guardian details.
5. Guardians check before, during, and after.
6. Send compliance declaration and dossier as completion notice; use after 2 weeks.
Contractors must inform clients on insurance and provide full delivery dossier.
Examples
New home build (class 1): Guardian verifies foundation and fire safety during construction; issues declaration for handover.
Tender for commercial building: Contractor supplies dossier proving compliance, key for public bids.
Shed construction (non-permit-free): Requires guardian, but no extended liability rules.
Tips
Early check via Environment Portal; select accredited guardian.
In tenders: Include assurance plan and dossier in bids for compliance edge.
Ensure defect insurance; transparently inform clients.
Use digital tools for dossiers to cut costs in projects.
