Fire risk calculations
We carry out fire risk calculations for reconstructed, renovated and modernised buildings to ensure a level of fire safety that is compliant with all applicable regulations.

When reconstructing, renovating or modernising buildings, structural constraints often make it simply impossible to comply literally with the fire safety rules. Once non-compliances with fire safety legislation are identified, we carry out fire risk calculations that objectively assess the real probability of a fire starting and spreading, and its possible consequences. This opens the way to performance-based (engineering) fire safety and to coordinating the design with the supervisory authorities.
Using state-of-the-art fire and evacuation modelling software, we prove that by implementing compensatory measures, the building will achieve a safety level that meets or exceeds regulatory requirements. This makes it possible to legally approve the design, preserve the building's architecture, and avoid expensive, excessive fire safety systems.
What problems do fire risk calculations solve?
- Justification of regulatory deviationsIf a building features insufficient staircase widths, excessive evacuation travel distances, inadequate fire separation distances between structures, or heritage restrictions, our calculations prove that implementing alternative measures keeps the building entirely safe.
- Significant cost optimisationWe help clients find more cost-effective compensatory measures, avoiding the need for expensive, technically complex, or excessive fire safety systems (such as automatic suppression systems that would require replacing the main water supply inlets).
- Smooth project approvalThe fire risk assessment report is an official document submitted for fire safety expert review and to the Fire and Rescue Department (PAGD), ensuring formal approval of the building's safety.
When should you contact us?
- 01During the design phaseWhen the architect realises that the prescriptive fire safety regulations cannot be met due to structural constraints during building reconstruction.
- 02After receiving expert remarksWhen the fire safety expert review or PAGD officers reject the design because of identified non-compliances.
- 03When changing building useWhen industrial or storage premises are converted for public, retail or residential spaces, and fire safety requirements become more stringent.
