FAQ

It would appear that a construction permit is not essential. Is this correct?

In certain, very specific cases it is not necessary. However, in the vast majority of cases a construction permit is mandatory, even for a temporary construction.

Is the mention of resistance to wind speeds of 160 km/h in technical or sales documents sufficient assurance that the proposed building is compliant with NV65?

The mere mention of resistance to a particular wind speed does not constitute the compliance of the building with the NV65 calculation regulation.

It is in fact important to verify that the resistance highlighted is compliant with that in force in your area of installation.

This also applies for the snow load and for additional factors such as the exposure of your site or its altitude.

In the same context, is the mention in a technical or sales document of a material compliant with NV 65 an indication of safety?

Yes, provided the contracting authority can guarantee that the factor of climatic load in his area are well taken into account in the dimensioning of the project. Only a written confirmation of the figures for the snow and wind zone and aggravating factors such as altitude, la distance from the sea or even seismic risk can guarantee their actual consideration in the calculations.

In this case, how can you assess compliance with NV65 with a degree of certainty?

The only infallible approach involves calling in a technical inspection agency to validate the building's resistance to cold conditions and to issue an opinion on the finite element calculation report.

Which fundamental criteria should I focus on before renting my dismantlable building?

Certain parameters can provide you with indications regarding your service provider's overall adherence to the NV65 standards:

  • the size and the cross-section of the profiles used for the frame, which may prove to be some way off the mark;
  • the techniques used for anchoring to the soil and for joining the parts of the frame, which indicate whether the main forces acting on the framework have been considered
  • the lack of reference to the NV65 regulations and to the framework calculation in the technical and sales documents
  • the mention of structural inspections carried out be a marquees, tents and temporary structures inspection body (bureau de vérification des chapiteaux et structures, BVCTS), which serves as legal validation of compliance with the CTS regulations, but not NV65
Am I responsible for an accident on site if I call in a professions who should himself ensure that basic safety rules are adhered to?

Yes. The co-responsibility of the contracting authority is clearly established.

It is not sufficient to confer responsibility to a service provider who is considered competent in this regard. With regard to safety, it is worth checking, and in fact acquiring written confirmation regarding the effective methods used by the service provider. Abnormally low construction site costs can be a sign that safety provisions are only being implemented partially or inadequately.

 

Do regulations regarding procedure in the event of a fire and how to avoid panic also apply to dismantlable buildings?

Regulations regarding fire and personal safety apply to dismantlable buildings. However, these rules differ depending on whether or not the building is intended to be open to the public.

Your service provider will assist you to ensure you fulfil these obligations.
