Structural Fire Engineering
Structural fire engineering assessments can reduce the structural fire resistance of elements of structure and show existing elements of structure are still suitable to support the fire safety strategy.
Each individual problem is highly unique and will be assessed by our experienced team.

CFD and Evacuation Modelling
Through the application of CFD modelling, smoke ventilation systems can be accurately designed as the complexity of the analysis is much greater. By producing our own performance specifications, clients are afforded flexibility in the choice of system provider, allowing them to benefit from more cost-effective solutions.
SOCOTEC provides the following services:
- Preparation of CFD models and associated reports
- Peer review of CFD reports prepared by others.
