We at NBG love details and information, even over far distances. With our technology, it is possible to measure changes in tunnels/mines in real-time 24/7. By analyzing measurement data, structural deformation trends can be predicted and the level of safety can be evaluated in order to timely find early defects. Having permanent and reliable monitoring data from the structure can guarantee the safety of the structure and its users. Monitoring discovers deficiencies in time as a few structures might present deficiencies which cannot be identified by visual inspection or modelling.
