Ground Penetrating Radar
Arizona Public Service contacted Encompass Inspections to determine a safe and obstruction free space to core multiple holes into the elevated concrete floor of the main lobby and many levels of the downtown Phoenix high rise building. The engineer’s main concern was to avoid the known rebar and electrical conduits inside the elevated concrete slabs during renovation of multiple floors to the APS downtown headquarters.
How We Responded
Encompass Inspections utilized Ground Penetrating Radar and Radio Detection to locate rebar and electrical conduits as it is a non-destructive geophysical device used for subsurface exploration. GPR operates by transmitting an electromagnetic pulse from an antenna into the ground and then capturing the partial reflections from subsurface layers showing possible reinforcement, conduits. APS Engineer’s also required a reliable, non-destructive means to locate targets within concrete structures prior to drilling, cutting or coring.
Results We Delivered
Encompass Inspections used the GSSI GPR 1600 cart in Concrete Mode along with Radio Detection in Power Mode to detect rebar/PT cable/conduit position accurately, and to determine depth of rebar/PT cable/conduit, detect PVC conduit and provide onsite results. Encompass Inspections was able to instantly provide on site analysis from the interpretations of multiple GPR images. The engineers placed paper down over the area needing structural calculations so that the granite flooring would not be comprised. After we performed the GPR scan we used the Radio Detection in Power Mode to sweep over the areas in a grid pattern to trace both low and high voltage conduits. Both of the methods Encompass Inspections used for the APS Headquarters provided the engineers instant direct layout of possible obstructions in the elevated slab and the safest areas for possible core drilling.
