Structural Health Monitoring allows rapid assessment of a tunnel’s state of health and such approach is becoming recognized as an appropriate mean to increase the safety and optimize operational and maintenance activities of tunnels. Data resulting from the monitoring program is used to improve the operation, the maintenance, the repair and the replacement of the structure based on objective results. Detection of ongoing damages can be used to discriminate deviations from design performance. Malfunctioning tunnels can often have serious consequences. The most severe are failures involving human victims. Even when there is no loss of life, populations suffer if the structure is partially or completely out of service. Learning how a tunnel performs in real conditions will help design better structures for the future. This can lead to cheaper, safer and more durable structures with increased reliability, performance and safety.

The TunnelTech 101 Visibility Monitor (VIS), is an essential part of any road or rail tunnel safety system. It monitors the Visibility within the tunnel and ensures that the tunnel ventilation system provides sufficient clean air for drivers to clearly see the road ahead. The TunnelTech 102 Cold smoke monitor (CSM detects smoke from a fire to rapidly warn the operator of the hazard. Secondly, used in combination with other TunnelTech 101 VIS monitors, the operator can quickly detect the locus of the fire if it is also equipped with the optional PT 101 temperature sensor to accurately measure ambient air temperature in a range of -15 to 1050C.

We have developed washing techniques and technologies for the military industry in keeping with high military standards of safety and efficiency, using water jets and the sanding power of aluminum oxide. We are currently creating an anchor profile that will allow us to file a plating patent application for an exclusive, entirely automated surface treatment which prolongs engine life in extreme conditions. At IST Pure, we also manufacture washing tunnels for the complete cleaning of military vehicles and ballistic equipment to prepare for and return from missions.
