  • Profile checks and setting out for portals, niches, cross cuts and inner linings

  • 3D displacement measurements and automatic monitoring

  • 3D net and control measurements

  • Geotechnical measurements and instrumentation

  • Nondestructive tests of tunnel inner linings based on guideline NDT-TU (in German: ZFP-TU)

  • Laser Scanning

In both parent companies, different hard- and software solutions are available for specific tasks in tunnel construction./:

  • Alignment laser for conventional tunneling

  • Motor laser systems which can be easily used by miners without the presence of a surveyor

  • Roadheaders control guidance systems

  • TBM guidance systems

  • Software packages for processing all relevant data and outputs
