Safety is guaranteed by the ventilation system

Tunnel ventilation maintains air quality at the required level. In the case of a fire, the main objective of a ventilation system is to protect users from smoke and toxic gas allowing them to reach the emergency exits. The design of the ventilation system depends mainly on the size and shape of the structure, the intensity, the type of traffic as well as the weather conditions at entrances and exits. BG’s work includes surveys, site supervision, and maintenance assistance.
