One of the most important aspects on a construction site is health and safety coordination. This involves controlling and minimising risks to your safety and health. It is therefore part of occupational health and safety at work, which requires measures for a humane work structure. These are the essential supporting processes of a company.

  1. Avoiding risks
  2. Assessing unavoidable risks
  3. Eliminating hazards at source
  4. Consideration of the human factor
  5. Consideration of the technical standard
  6. Eliminating or reducing risks
  7. Risk prevention planning
  8. giving priority to collective over individual protection
  9. giving appropriate instructions to workers
  1. Sanitary installations WC, etc. and their numbers.

  2. Construction equipment (fixing the access road, backfilling, possibly underpinning)

  3. Description of the construction site

  4. Duration of the construction site; start of construction, construction companies involved, emergency police hospital fire brigade

  4. AS Plan constructed by construction companies

  5. Has the PPSS been sent to the safety office?

  1. Coordinate the application of the general principles

  2. Develop a safety and health plan including the provisions applicable to the site in question. The specific measures and tasks in the safety and health plan should be incorporated into the tender documents.

  3. Compile a Built DAO document and record the relevant health and safety information to be taken into account in all subsequent work.

  4. Ensure that the general principles of health and safety prevention set out in the Health and Safety of Workers at Work Act of 31 July 2006 are taken into account by the contractor and, where appropriate, the client, including the following

  5. Estimating the time needed to carry out the work

  6. Drawing up a comprehensive health and safety plan specific to the site concerned, taking into account the work on the site. The plan must also contain specific measures relating to work falling under one or more categories of Annex II of the Grand Ducal Regulation of 29 October 2004 and the elements covered by Annex V of the Grand Ducal Regulation.

  7. The specific indications and measures of the general health and safety plan must be included in the tender documents.

  8. Draw up a list, adapted to the construction site, of the health and safety elements to be adopted in the event of subsequent work. The elements listed in Annex VIII of the Grand Ducal Regulation of 29 October 2004 must also be adopted.

  1. Coordinates the compilation of general prevention and safety principles :
    • Making technical and/or organisational decisions to plan the various jobs or stages of work taking place simultaneously or consecutively.
    • To estimate the time needed to carry out these different works or stages of work ;
  2. Coordinate the implementation of relevant regulations to ensure the protection of workers on the part of employers:
    • Consistently implement the principles set out in paragraph 4.2;
    • Implement, if necessary, the general health and safety plan referred to in paragraph 3.1.b ;
  3. Makes the necessary adjustments to the general safety and health plan from paragraph 3.1.b and in accordance with paragraph 3.1.c, according to the progress of the work and changes, and according to the additional information in the establishments’ specific safety and health plans.
  4. Organizes between employers, including those operating on site, cooperation and coordination of activities for the protection of workers and prevention of accidents and damage to occupational health risks, and follow the mutual informations contained in the Law of 31 July 2006 Book III concerning the safety and health of workers at work.
  5. Coordinates the supervision of the proper application of work procedures;
  6. Ensures that the necessary measures are taken to ensure that only authorised persons have access to the site.

With regard to the minimum health and safety requirements to be met on temporary or mobile construction sites, each client is obliged to appoint one or more health and safety coordinators (SiGeKo) for each construction site where at least two companies are active (simultaneously or successively).

For this purpose, they may use specialised third parties, such as the approved SiGeKo.

These specialists, who carry out this activity under their own responsibility, will then explain the relevant technical details to you (for example, the “general health and safety plan”).

If the SiGeKo has a subordinate relationship (employment contract) with you, the coordination task must be recorded in a separate written document. If several construction works are to be carried out simultaneously by several builders on the same site, the respective SiGeKo are obliged to consult each other in order to prevent the risks resulting from the mutual interference of these interventions.

There are two types of SiGeKo, one for the conceptual (planning) phase of the construction and one for the realisation of the project (site phase). A contract between the client and the SiGeKo explains, among other things, the tasks to be performed by the SiGeKo and the beginning and end of the latter’s obligations.

The Client, who uses a secondment company, is informed that in case of non-compliance by this company with local legislation, its activities, respectively those of its seconded personnel, may be temporarily, partially or totally interrupted.

There are 4 important conditions that must be fulfilled with regard to the notice (AP):


If it is a construction site of a certain size:- where the estimated duration of the construction project is more than 30 working days and more than 20 workers are employed at the same time,- OR the estimated volume of construction is more extensive than 500 “man-days”; the client is obliged to send a <written notice> to the ITM via its SiGeKo.

The <written notice> (“AP”) must be prepared in accordance with Annex III of the G.V. of 28 June 2008 and must be communicated at least 10 working days before the start of the construction activity.


It is mandatory that the “written notice” be posted (visibly) on the work site (preferably on the outside grills of the work site under a plastic protection (against bad weather).


The notice should preferably be sent to the following email address: Otherwise, the <written notice> shall be delivered to the postal address of the ITM (<INSPECTION du TRAVAIL et des MINES> : Département : <Construction>), boîte postale 27 à L-2010 Luxembourg.


The “written notice” must be updated as necessary. Any update in the employment situation or working conditions at the work site must be communicated to the ITM without delay. (For example, in the event of a substantial increase in the number of workers or the anticipated start of activity by new companies or subcontractors at the worksite.
