them to place the SX10 in optimal locations for both
scanning and conventional total station measurements.
Rather than removing the vault grating, crews could use
smaller openings to safely measure the equipment in
the vault. By placing the SX10 in strategic locations to
scan the vault, they completed the work with just three
setups in half a day. Surveying the remainder of the
site required another half day and included scanning as
well as prism measurements for precise location of the
excavated pipes. The SX10 also captured high-resolution
digital images of the site and equipment. In all, the crews
visited the site on three separate days to set control and
capture comprehensive data.
INTEGRATING COMPLEX
INFORMATION
SOA technicians used Trimble Business Center Software
(TBC) throughout the project. For the control, they
combined data from the SX10 as well as digital levels and
Trimble R10 GNSS receivers. "Most of our GNSS work is
done with Trimble VRS," Trevino said. "And we have long
used TBC for QA/QC on our data and for computing control
coordinates."
Using TBC's scanning module, SOA technicians
quickly combined all of the scans from the project site.
Because all setups were resected onto project control
Finished 3D model of the vault developed from SX10 scanning data.
Combined point clouds provide complete data on piping and
equipment in sunken vault.
Image data from the Trimble SX10 combines with point cloud to
provide accurate 3D information.
