Ground Penetrating Radar Systems, Inc. was contacted by the Auraria Higher Education Center in regards to a project at the Media Center Building. The AHEC campus is home to the Community College of Denver, the Metropolitan State University of Denver, and the University of Colorado Denver. AHEC needed to saw-cut the concrete floor in multiple locations of the basement.
However, they had worries about striking conduit in the concrete flooring while they were saw-cutting. This is where the use of GPR was needed to come in and map out the two areas that needed to be saw-cut and identify any conduits running through the concrete slab. Ground radar is the only logical method available to examine a concrete slab on grade, as concrete x-ray is not able to scan concrete unless there is access to both sides of the concrete.
In these pictures you can see the pipes below the concrete after the saw-cutting was already completed.
GPRS of Colorado was able to mobilize to the site and while on the campus a conduit was located in the floor and marked directly onto the surface. Because GPR data is received in real time the information of what lies below the concrete can be mapped on the surface immediately. AHEC was then able to cut around the areas where conduit was located and then go back and chip out concrete around the line to ensure no conduits were hit.
Here a GPRS technician scans the surface of the concrete. After the survey the conduit located was mapped on the surface.
If you are worried about striking conduits, rebar or post-tension cables during coring or saw-cutting in Colorado, New Mexico, Utah or Nebraska contact Ground Penetrating Radar Systems Inc. regional director Jason Schaff at 303.945.5415 or by email at firstname.lastname@example.org.
