Core drilling numerous holes on an elevated slab can be a difficult challenge due to the fact that you are not able to see where existing structures are below the elevated slab or any utilities that are embedded in the concrete itself. Ground penetrating radar can be used to provide the answers to these questions. Having a properly trained GPR technician onsite can help create a less stressful & safer environment for everyone involved on the construction project.
GPRS of Michigan was recently contacted by a general contractor to scan the concrete in several areas inside a hospital in Royal Oak MI. Numerous holes had to be core drilled in the future to connect to existing utilities below. The elevated concrete slab had structural beams supporting the deck. It was essential that the general contractor not drill into any of these concrete beams. They did not have any as-built drawings showing paths of possible conduits passing through the space that may have been embedded in the concrete slab. GPRS was able to utilize a 1600 MHz concrete antenna to scan all areas to locate the structural support beams. They also marked multiple conduits that were passing through the space. Everything was marked directly on the surface in a clear manner so everyone involved with the coring process had an understanding on what areas could be drilled and the areas to avoid.
Prior to saw cutting, core drilling, excavating or boring in the Ann Arbor/Detroit areas, be safe & get as many questions answered as to what sub-surface obstructions are present. Contact GPRS Regional Manager, Thaddeus Bullock, at 734.377.4551 or email@example.com.
