    Multisensor Systems for Tunnel Measurement


    Tunnels are critical components of transport infrastructure. Structural defects, such as cracks or water inlets in tunnel constructions, are a major risk. To ensure adequate security, legislation requires regular monitoring of deformation. Nowadays, cameras and classical measuring devices are used for inspections using various measurement techniques. Processes are tedious and costly. The data obtained are in a wide variety of formats and the degree of digitalization is minimal.

    Digital measurement data play an important role in long-term structural monitoring as well as optimized construction planning in line with Building Information Modeling (BIM).

    In the future, a compact multi-sensor system will provide precise and objective measurement data of tunnel structures. The system will collect data related to geometry, surface structure and water input in a single measurement procedure in the tunnels and provide measurement data compatible with BIM in digital format. For the realization of this technology, the German AKG company group, Amberg Technologies AG from Switzerland and Elaborarium SL from Spain started to work together with Fraunhofer IPM as a partner in a joint project in the integrated audit process in which a new multi-sensor system will be developed.
