Tunnel Systems

Tunnels systems provides the foundation for a safe environment for the tunnel user, providing ventilation and safety features appropriate for the tunnel and surrounding environment.  In designing a new tunnel, it is vital that early consideration be given to ventilation issues. Our understanding of the inner-relationship between tunnels design and tunnel ventilation results in a cost–effective design that optimizes system performance and safety of the traveling public. Expertise includes:

• Environmentally sensitive design to minimize adverse effects inside the tunnel and within the tunnel vicinity including noise attenuation measures and integration of ventilation facilities with architectural; features
• Design and implementation of facilities for the safe collection and disposal of hazardous spills
• Experience in analyzing levels of carbon monoxide and other pollutants in the tunnel environment and designing the ventilation system to maintain high air quality
• Simulations of exhaust emissions, dispersion from tunnel portals, and designing measures to alter the dispersion pattern such as changing the portal design or by introducing a portal ventilation facility
