Fire, Smoke + Tunnel Modelling

We support investigations into the cause and behaviour of fire incidents, using CFD calculations to analyse the influence of the framework conditions on a fire’s behaviour. 3-D simulations offer insight into the behaviour of the fire, as well as the ventilation conditions, to determine the events that unfolded during the incident.

Our experts provide robust solutions to solve the most complex tunnel ventilation challenges. We can undertake a qualitative risk analysis to assess a ventilation system’s capability to limit the effects of any fire developing in a rail or road tunnel. A combination of 1-D and 3-D modelling and analysis for smoke propagation and movement, ambient temperature and evacuation needs can be used to produce a preliminary design and map out the functional requirements. Using the results of this analysis, we can determine which measures are appropriate to ensure optimum fire safety within the tunnel. This can also inform the contractual framework for installing the ideal ventilation system.

With dispersion modelling, we can help you evaluate hazard potential and understand how your project may impact the environment. Using our advanced modelling capabilities, we can assess hazards – like smoke from a ventilation shaft, tunnel or car park, a combustible gas leak, or a flame stack plume - so you can consider remedial measures and significantly impact the probability of a reoccurrence happening.

Complex building designs, new construction materials and ever-changing building lay-outs pose challenges to properly addressing evacuation in modern buildings. Utilising the latest fire safety modelling, we can check the safety level of the building using real time evacuation data and simulations of fire and smoke spread throughout a building. In addition, we can integrate fire safety into BIM models, providing valuable insights to contractors and architects from the start of the building process. Using one aggregate model allows a streamlined design process and increases the potential to collaborate.
