Taking As-Built Measurements

To check elevation and position during production, Leica PaveSmart 3D has an integrated
as-built (Control) function, depending on the instrument type, to replace the manual
"dipping" method used when working on string line. Regular, independent as-built measure-
ments are essential to verify product is in project tolerances.
Measurements are only possible if the instrument is correctly positioned and orientated
within the project coordinate system (Free Station or Known Point setup)
Refer to the MGUIDE User Manual for the instrument type and for detailed instructions on
making as-built measurements. Customers using
the PowerTracker or iCON User Manual and the Geo-Pad User Manual or Site Foreman User
Manual on how to take As-built measurements.
Immediately after an As-built control measurement has been made the results can be seen
in the Work\Design dialog. The results are also recorded in the active project folder in the
file Asbuilt.abr. Work: Menu \ Projects \ AsBuilt, and can be exported to provide a perma-
nent quality-assurance record.
Care must be taken when taking as-built measurements very close to a free-standing edge
on freshly slipformed concrete or uncompacted asphalt - this may give misleading results,
due to the uncontrollable slump of the material at the unsupported edge. It is also
extremely important to ensure the correct Rod Height is used in the as-built checks, and that
the tip of the survey pole does not "sink" into the fresh material. Always use a small foot-
plate, adding its thickness to the Rod/Prism Height to ensure accurate measurements.
