The survey crew walked through the cave to plan for the best scanning positions
A laser scan of the cave’s interior helps surveyors accurately measure distances between points

Wade Trim surveyors recently went underground in the City of Frankfort, Kentucky,
to perform laser scanning throughout a 1,300-foot long cave. The City needed to
know if the existing, 50-year-old, 14-inch sewer running through the cave could be
supplemented with a 30-inch sewer. Global Positioning System and robotic total stations
were used to establish control points at the entrances and inside the cave. For six
days, the cave interior and pipe were scanned to produce plan, profile and cross-section
sheets to aid the City and their consultant, Quest Engineering, in their decision-making
process.
Wade Trim uses laser scanning technology for architectural, engineering and surveying
projects to increase accuracy and efficiency, improve employee safety and reduce costs.
Laser scanning is an exciting and beneficial alternative for the collection of as-built
data for a variety of projects.
