What are the EU prior notice and coordinator requirements?

Question

Accepted Answer

The directive's prior notice threshold works on two arms: work lasting longer than 30 working days with more than 20 workers at the same time, OR work exceeding 500 person-days. The notice goes to the competent authority before work begins and is displayed on site. The coordinator duty depends not on numbers but on structure: on every site with more than one contractor, one or more coordinators are appointed for the preparation and construction stages. The prior notice threshold Threshold Measure Duration + headcount Longer than 30 working days with more than 20 workers at the same time Volume of work More than 500 person-days The notice goes to the competent authority before work starts and is displayed on site . Türkiye's counterpart uses the same logic and the same numbers: the thresholds survived transposition. Coordinator: structure, not size The coordinator duty depends on the number of contractors , not workers. Where more than one contractor is present, coordinators are appointed for the preparation and construction stages — a single-contractor site does not trigger it. What we could not measure Annex III lists the content of the prior notice. In the published source that annex appears as an image , so it could not be read as text — which is why we do not list its content items here. Presenting an unmeasured item as measured is precisely what these pages do not do. Transposition differences The directive does not apply directly; each member state transposes it. Thresholds are usually preserved; the procedure and the authority change.

Obligation	Legal basis	How the page covers it
Where more than one employer or subcontractor is present on the same construction site, the employer or the project supervisor must assign one or more health and safety coordinators.	Regulation on OHS in Construction Work, art. 8(1)	The Turkish counterpart follows the same logic: the coordinator duty depends on the number of parties on site.
Where the work will last more than 30 working days with more than 20 workers employed continuously, or where the volume of work exceeds 500 person-days, a notification containing the particulars in Annex 3 must be given to the provincial directorate before work starts.	Regulation on OHS in Construction Work, art. 8(4)	Prior-notice threshold: the Turkish counterpart uses the same logic and the same numbers — the thresholds were preserved in transposition.
A board bearing the notified particulars must be placed at a suitable and clearly visible point on the site and updated where necessary.	Regulation on OHS in Construction Work, art. 8(5)	The notice is communicated to the authority before work starts and is displayed on site.

Obligation	Legal basis	How the page covers it
The client or the project supervisor shall appoint one or more coordinators for safety and health matters for any construction site on which more than one contractor is present.	Directive 92/57/EEC, art. 3(1)	Coordinator: structure, not headcount — the duty depends on the number of contractors on site, not on the number of workers.
The client or the project supervisor shall ensure that prior to the setting up of a construction site a safety and health plan is drawn up.	Directive 92/57/EEC, art. 3(2)	The prior notice and the plan are separate duties; the plan is drawn up before the site is set up.
Where work is scheduled to last longer than 30 working days with more than 20 workers occupied simultaneously, or the volume of work is scheduled to exceed 500 person-days, a prior notice shall be communicated to the competent authorities before work starts and clearly displayed on the site.	Directive 92/57/EEC, art. 3(3)	Prior-notice threshold table: duration plus headcount, or volume of work; the notice goes out before work starts and is displayed on site.
Where a client or project supervisor has appointed a coordinator, this does not relieve the client or project supervisor of his responsibilities.	Directive 92/57/EEC, art. 7(1)	Transposition difference: procedure and authority change, the seat of responsibility does not.
