Quality Assurance Act (Wkb).

You need to hire someone for construction supervision, a quality assurance contractor, in some cases. And you must report this to the municipality. This is called a Notification of Quality Assurance Act (Wkb notification). You can do this through the Environment Desk. Do the Wkb-notification at least 4 weeks before the start of the work. 

Currently, only new construction of simple structures, such as single-family homes and smaller commercial buildings, requires a Wkb notification. Health then that you hire the quality assurance officer in time. He will first assess the building plan. And then you can make the notification. Providers of quality assurance can be found on the website of the Ministry. 

Notification Quality Assurer

You can do the notification yourself, but someone else may also do it for you. For example, the quality assurance company. You should enclose the following information with the Wkb notification:

  • quality assurance name
  • What tool the quality assurance company uses. This is the quality assurance officer's method, which includes how the quality assurance officer works. It also says how he keeps in touch with you and what you can do if you disagree with the quality assurance officer.
  • a risk assessment. The quality assurance contractor must pay attention to the Special local conditions quality assurance.
  • an assurance plan. This states, for example, who inspects the structure and when.

If new risks arise during construction, the municipality may request additional information.

Special local conditions
