Tunnel Ventilation Design

Our small team of tunnel ventilation experts have extensive experience designing European tunnels to PIARC standards.

Our tunnel ventilation team can provide advice for amenity and fire emergency ventilation, including:

  • Sizing tunnel cross sections and entries,
  • Sizing and positioning ventilation systems,
  • Accommodating different locations of fires within tunnels, and
  • Accommodating and working with wind pressures and gradients,
  • Creating beneficial acoustic and energy outcomes.
We are able to simulate the optimal ventilation design during a tunnel fire by utilising a smoke exhaust model similar to the image above.
Alongside the smoke exhaust model, we can produce a temperature slice of how heat will travel within the tunnel.
