Supervision and Enforcement Policy for the Quality Assurance for Building Act (Wkb) – Groningen Municipal Regulations
The Beleidsregels toezicht en handhaving Wet kwaliteitsborging voor het bouwen is a formal policy document issued by the Board of the Municipality of Groningen, Netherlands. Effective from 26 July 2024, these regulations establish the framework for how the municipal authority evaluates construction notices, conducts supervision, and enforces compliance under the Wet kwaliteitsborging voor het bouwen (Wkb) and the Omgevingswet (Ow). The document outlines the municipality's transition from technical building plan checks to a process-oriented supervisory role focused on private quality assurance.
The scope of this policy primarily concerns new construction projects falling under Gevolgklasse 1 (consequence class 1), which represent low-risk buildings. It details the mandatory involvement of a private kwaliteitsborger (quality assurer) and the shift of technical verification from the municipality to these private actors. The document is structured into four chapters covering the introduction of the law, the construction notice (bouwmelding) phase, supervision during construction, and the completion notice (gereedmelding) and occupancy phase, followed by a comprehensive Interventiematrix (enforcement matrix).
These guidelines clarify that the Municipality of Groningen does not perform preventive technical checks or standard construction site supervision for Wkb projects. Instead, it utilizes a risk-based approach, including a 5% random audit (steekproef) of accepted notices to verify that the quality assurance system is functioning correctly and addressing local circumstances.
Supervision Strategy and Local Risks
The municipality has adopted a specific role in the quality assurance process, characterized by the following principles:
- Process-oriented supervision: The authority performs process audits rather than substantive technical assessments of building plans.
- 5% Audit Rate: A random sample of 5% of accepted notices is selected for on-site process checks.
- Local circumstances: Quality assurers must account for specific local risks, such as soil conditions or seismic activity, which the municipality publishes on its official website.
Construction Notice and Start of Works
Before construction begins, a complete bouwmelding must be submitted. Legal consequences apply if works commence prematurely or without a valid notice:
- 4-week Period: Construction may only officially start four weeks after a complete notice has been submitted.
- Incomplete Notice: A notice missing required data is legally considered non-existent and will not be processed.
- Enforcement Actions: Starting without a notice or with an incomplete notice results in a bouwstop (stop-work order) and potential administrative fines (last onder dwangsom).
Monitoring During Construction
The private kwaliteitsborger is responsible for ensuring the building meets the requirements of the Besluit bouwwerken leefomgeving (BBL). The municipality intervenes if the quality assurer signals unresolved issues regarding:
- Structural Safety: Irreversible errors in structural calculations or execution.
- Fire Safety: Violations of fire prevention regulations and compartmentation.
- Health and Sustainability: Non-compliance with ventilation, insulation values, or solar panel requirements.
Completion and Occupancy Requirements
A building may not be occupied without a valid gereedmelding (completion notice), which must include a statement from the quality assurer confirming the works comply with the BBL. The policy defines specific handling for:
- Missing Declarations: If a completion declaration is missing due to safety concerns, occupancy is prohibited.
- Phased Occupancy: For large housing projects, a full completion notice is required two weeks before each phase is occupied.
- Casco Construction: If elements like kitchens or bathrooms required by the BBL are missing, the quality assurer cannot issue a final statement until these are completed via a supplementary assignment.
Frequently Asked Questions
What is Gevolgklasse 1 in the context of the Wkb?
Gevolgklasse 1 refers to buildings with a low risk profile, such as ground-bound dwellings and simple industrial buildings, which are the first to fall under the mandatory private quality assurance regime.
What happens if I start building within the 4-week notice period?
Starting works within the 4-week period following the construction notice is at the builder's own risk; the municipality may issue a stop-work order until the period has expired.
How does the Municipality of Groningen handle a missing completion declaration?
The municipality assesses the situation based on safety risks; if structural or fire safety is uncertain, a prohibition on occupancy is enforced, and the owner may be required to perform destructive testing to prove compliance.
Are seismic risks in Groningen considered in the building process?
Yes, local circumstances including soil conditions and seismic risks must be incorporated into the quality assurer's risk analysis as specified in section 1:3 of the policy.
What occurs if the quality assurer stops their work during a project?
A new quality assurer must be appointed, and their details must be disclosed to the municipality, although a new construction notice is generally not required if the project remains unchanged.
Can the municipality still perform an on-site check?
Yes, the municipality conducts random audits on 5% of projects and may also perform inspections based on complaints or observations of irregularities during other permit checks.
