Electrical Conduit Locating
Company in Ann Arbor, Michigan

The University of Michigan Construction Services Department recently contracted with GPRS to scan the Simpson parking garage prior to new floor slab penetrations. The specifications called for (2) 4” diameter holes to be drilled on the 2nd -7th floors. The university was concerned about hitting rebar and any unknown electrical conduit that was embedded in the slab. Once the areas were scanned, marking were made directly on the concretes surface for a grid layout. The entire process took only 3 hours and results were immediate.

In other related news, GPRS was again hired by the University of Michigan for a project at the University Hospital. This time GPRS was called in on a project that required floor scanning at 4 locations for new AV boxes. Due to the relatively close locations of the AV floor boxes to structural support beams, all the reinforcing steel needed to be located and analyzed for spacing and depth. The structural engineer on the project needed as much information on the rebar as possible so that an educated assessment on what bars to cut could be made.

top bars, and the green line indicates a conduit in the slab

As you can see, the amount of reinforcing steel was extremely dense in the scanned area. GPRS was able to layout the rebar locations and identify top and bottom bars immediately while scanning. It is not uncommon for GPRS to scan sizable areas such as these within just a few hours. For questions or to receive a quote, contact John Kessinger at 734.377.4551 or at john.kessinger@gp-radar.com
