Scan profile
A tunnel surface is scanned in detail during construction and/or at the comple-
tion of construction to detect overbreak, underbreak and/or to create an 'as
built plan' of the finished tunnel surface.
Scan profile
allows measuring a user-defined number of tunnel profiles along
an existing tunnel alignment.
It can be defined:
•
Whether to scan the whole tunnel profile or just a segment of it.
•
The interval between measurements around the profile.
It does not matter if a design profile exists in the job or not.
If the job does not contain a design profile, then before scanning the defined
scan area the instrument will first scan a profile at the instrument chainage.
