TEKIA and tunnel ventilation

At TEKIA, our experience in different urban and high-speed railways allows us to offer safety engineering solutions that cover everything, from designing the system to defining operations and emergency procedures.

During the commissioning of a tunnel, and also regularly during its use, the ventilation system should be audited. TEKIA uses a contrast methodology to assess the tunnel ventilation and evacuation system design based on 3D simulation and on-site tests carried out with our own equipment.

At TEKIA, we have been involved in over 100 ventilation projects in both road tunnels and railway tunnels around the world.
