Send advance notice of a construction site

If you are the owner of a construction site or have been given responsibility for a construction site, you must, under certain conditions, send an advance notice to the relevant health and safety authority at least 2 weeks before the construction site is set up. You must submit an advance notice if

• the expected duration of the work is more than 30 working days and more than 20 employees will be working on the construction site at the same time (i.e. over a period of at least one working shift) or
• the scope of your construction work is expected to exceed 500 person-days (one person-day being the labour input of one person over one shift).

Setting up the construction site begins with the essential preparatory work at the site of the construction project that is required immediately prior to its realisation. This includes, for example

• Construction of social facilities: for example toilets, break rooms or washrooms,
• Installation of supply and disposal facilities,
• Delivery of building materials, machinery and equipment.

You must also post the advance notice on the construction site on the first day of the construction site at the latest. Please note that

• the advance notice is clearly visible,
• the advance notice remains legible and unaffected by external influences and weather conditions,
• the advance notice is updated if there are significant changes. It is not necessary to resubmit the notification to the competent labour protection authority.

Significant changes that require an adjustment to the advance notice are, for example

• Change building owners or authorised third parties,
• Coordinator is newly appointed or changes,
• The duration of construction work is shortened, which means that more work has to be carried out simultaneously or in unplanned shifts,
• employees of several employers or subcontractors are working on the construction site at the same time for the first time,
• the number of people working on the construction site at the same time or the number of employers or companies without employees increases significantly.
