- Rapid, comprehensive and unbiased documentation
of the rock mass during excavation
(later verfication of the actual conditions)
- Objective data basis for decision-making concerning
further construction, support or
excavation planning, respectively
- Improved analysis including
- spatial rock mass observations on the computer
- contactless measurements of distances, areas,
orientations in 3D
- determination of geotechnical parameters
- simple change of observation scale
- analysis without pressure of time
- Increased safety
- no manual contact needed for measurements
- no work in insecure areas, e.g. at the unsupported
tunnel face
- Scalable system that allows different object
sizes, from several metres to several hundred metres
height
- Reduced mapping effort especially in regions with
difficult access
- Cost savings in planning construction
