If you are planning to carry out construction work in the Netherlands (as a client or main contractor), you must notify the SZW Inspectorate (Inspectie SZW) in advance if:
- it is estimated that the construction work will take more than 30 working days to complete and if more than 20 employees will be working on the construction site at the same time;
- it is estimated that the construction work will take more than 500 man-days to complete.
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.
