RAILWAYS The excellence of collaboration

Inspection • The easy comparison of multiple inspection periods
Intact tunnel structures are necessary to guarantee safe and • The accurate results
economic operation, so what is a precondition to facilitate an • The monitoring of damage overtime
economical life cycle management is the:
• The speed – minimum time presence in track
• The safety – minimum personnel presence in track
• Inspection of the tunnel on regular time basis, or after an
incident
• Acknowledgement and documentation of current tunnel
structure condition
• Allocation, classification and monitoring of damages
• Data Base creation of tunnel’s condition

By using the same mobile mapping method as for envelope
clearance, dense point cloud data is collected, exporting
projected high definition images of the tunnel surface.

With predefined tunnel structure and geometry of inspectables,
next step is the digitalization of recognizable damage, Inspection sheet
structural features & equipment.

The automatic generation of inspection result overviews is one EXPERIENCE
of the benefits that this non-conventional method offers. Also
