Tunnel review
Create reports of the as-built tunnel in the field to:
-
Check that the tunnel construction matches the design.
Assess the excavation, shotcrete, and lining process.
-
Report on deltas between the staked location and design point for quality control.
-
Report on tunnel volumes for underbreak and overbreak analysis.
-
Share progress information with stakeholders and clients.
Reports show survey results for scanned points, manually measured points, and set out points.
All scanned, measured and set out points are face 1 measurements and are stored in the database. You can review them in the Review Job screen.
When reviewing a tunnel the number of points within or outside tolerance and their delta values is controlled by the tolerance values defined when the tunnel was scanned. To edit these tolerance values after a survey, select Tolerance from the tap and hold menu at the plan or cross section review screens. This option is useful if incorrect values were specified for the survey.
