The use of laser scanner systems in tunnel construction projects offers advantages and potentials for use both to owners and construction companies. Virtually spatial recording of the excavation profile enables significant cost savings through targeted quality improvement with respect to the quality of the excavation profile and optimisation of the concrete strength.

By accurately determining the measurements, the scanner recordings can also be utilised as an important basis for billing. Scanner records are also suited for geological purposes (especially when augmented by camera data), for analysis of deformation and to secure evidence.
