If you are planning to carry out construction work or renovation work in the Netherlands (as a client or main contractor), you must notify (in Dutch) the SZW Inspectorate (Inspectie SZW) in advance in the following cases:
- if the construction work is estimated to take more than 30 working days to complete and more than 20 employees will be working on site at the same time;
- if the construction work is estimated to take more than 500 man-days to complete (for example, 10 employees working for 50 days or 5 employees working for 100 days).
You must send in the notification to SZW Inspectorate before starting the activities. You put up a copy of the notification at the building site and notify SZW Inspectorate of any changes to the construction work. Finally, you must draw up a Health and Safety Plan.
