A way out of manual inspection
Modern transport infrastructure would be inconceivable without tunnels. In Germany, there are more than 400 road, rail and underground tunnels requiring regular maintenance. Many of these tunnels have been in operation for decades, so regular maintenance and repair are becoming increasingly important in order to avoid safety risks and consequential damage. Today, an inspection is performed manually in a slow, costly and unobjective process – the degree of digitization is low. In the near future, however, Building Information Modeling (BIM) will also become standard in tunnel construction. This will require the complete digitization of building surveying. Fraunhofer IPM develops technical measurement solutions for a cost- and time-efficient inspection process during regular operation.
