The University of Colorado at Denver needed several holes cored on the roof of the campus in downtown Denver. Rhinotrax Construction was in charge of the site and was instructed to miss all rebar when coring through the roof. Larry Wieker of Rhinotrax Construction called Ground Penetrating Radar Systems, Inc. of Denver, Colorado to ensure that no rebar was hit in the coring process.
GPRS of Denver, Colorado mobilized to the site and was able to map out the location of the rebar within the concrete roof. All six locations were scanned using GSSI Ground Penetrating Radar equipment. Located on the floor below where the scanning was to take place were classrooms full of students that could not have been evacuated if concrete x-ray was used. The radiation that concrete x-ray emits would have created a need to move teachers and students to another location, interrupting everyday business. GPR does not emit any radiation and therefore was ideal for the rebar investigation.

Concrete scanning for the purposes of identifying the location of rebar and post-tensioning is the most frequent service performed by the GPR technicians at GPRS.
