Norway’s unique landscape necessitates one of the most extensive tunnel networks in the world. 1800 road and rail tunnels contribute to 9000km of tunnel in Norway. These are inspected manually by eye and on foot, a time-consuming and hazardous process producing only qualitative data on tunnel safety. To combat these issues, Techrail aims to provide an integrated solution that is safer for inspectors, that does not interfere with traffic, and more comprehensively evaluates the safety of tunnels. Our solution enables the measuring the change of a tunnel’s surface over time, which allows tunnel directors to predict maintenance needs and more accurately evaluate the state of their tunnels. A digital paper trail will also aid regulators in overseeing tunnel maintenance. Furthermore, our technology has a large number of secondary uses that provide value such as Building Information Modeling (BIM), tunnel construction, and crack detection.
