GPR Locates Electrical Conduits
The church has hired Western Mechanical as its lead contractor for the project. One of the issues that quickly developed was how new floor ducts were going to be installed without hitting embedded electrical conduits and rebar. Since the sanctuary was technically on the 2nd level, the floor slab was a suspended slab construction with a basement beneath it. As built drawings showed several electrical conduit runs in the slab and needed to be avoided during the drilling. GPRS was contact by Mr. Bill Matheson, project manager for Western Mechanical. One of the challenges during this phase of the project was how to mark the floor where conduits were located without making any sort of permanent marking. The floor was a granite slate and would not be removed or replaced during construction. It was decided to place duct tape on the floor and then to transfer the findings onto construction drawings for future records. Although some of the conduit locations matched with the as-built drawings, many did not. Without using ground penetrating radar it would have been a guessing game for the contractors to safely drill.
Within a couple days time, GPRS was able to accurately map out the electrical conduits and rebar throughout the large sanctuary. Although the job proved challenging from a marking perspective, the experience GPRS brought to the job proved a worthy investment for all parties involved. Should you need to cut, drill, or dig, consider utilizing ground penetrating radar on your next project.

One of Southeast Michigan’s most historical churches is undergoing interior renovations. Built in the early 1900’s, it’s no wonder the current heating and cooling system installed in the sanctuary is out of date with current standards. Many church members and staff had experienced poor ventilation during services in the winter and summer months, which caused for some uncomfortable conditions during services.
