What we were asked to do for this project
ACS Underground Solutions was hired to conduct an underground GPR survey to investigate voids in a 30’ x 15’ roadway area in NYC.
How we successfully completed this project
Our technician arrived on site and reviewed utility drawings with client. The work boundaries where the GPR Survey took place were defined. Our technician scanned the area using Ground Penetrating Radar with a 500 MHz antenna and successfully detected and located voids approximately 1ft below the surface. Another void was located at an electric manhole along curb heading towards Park Avenue in Manhattan. Manhole in street was scanned and showed section of collapsed asphalt between manhole and sidewalk. As the voids were located, they were marked-out on the ground with white paint for further reference. ACS technician also used Cable Avoidance Tool (CAT) locator to verify an electric conduit. A report summary was provided to the client upon completion of the underground survey work performed by ACS.
Ground Penetrating Radar (GPR) uses radio waves to detect and locate underground voids and cavities that may cause issues such as:
When the machine is pushed across the ground surface of the subsurface area under investigation radio waves are simultaneously reflected to the equipment’s monitor. The image is then recorded as to what is being seen underground. ACS experienced technician’s are specially trained to determine what these images represent.
