Concrete Imaging Services for 161 William St.

On 12/1/21, AmeriscanGPR provided concrete imaging services at 161 William St. The purpose of this survey was to map rebar patterns and locate any in-slab electrical conduits or other obstructions that may interfere with the proposed slab penetrations. In order to do so, we used ground penetrating radar (GPR) and radiodetection technology. The specific equipment used for this scope of work was: The Conquest Concrete Imaging System and the RD7000 Radiodetection Wand. The Conquest GPR unit specializes in evaluating concrete structures and detecting embedded metallic & non-metallic objects. In order to collect data, grid scans were performed, which collect cross-sectional lines to produce 3D concrete slice images. The RD7000 Radiodetection unit, when set to power mode, is able to detect the electromagnetic field surrounding electrical lines.

Here's a picture of the area scanned:
