GPRS Locates Utility Lines at Airport - Columbia, SC

Ground Penetrating Radar Systems was recently contacted to locate all utilities at the Columbia Metropolitan Airport in Columbia, SC prior to directional boring. The equipment used in the scan was a 400MHz antenna capable of identifying objects at a depths of up to 6-7’, RD7000, and a SIR-3000 computer system.

Utility Mapping with GPR - Columbia, SC

The equipment used in the survey was:

  • The equipment used in the survey was: GSSI Ground Penetrating Radar – This device transmits an electromagnetic pulse through the ground and displays the reflection on a screen for interpretation.
  • 400 MHz antenna – This antenna allows for GPR signal penetration 4’-8’ through the ground.
  • RD-7000 locator – This device detects live power and RF signals underground, allowing us to locate electrical or telephone lines even if they are below the minimum size requirements to be detected by GPR. It also allows us to detect utilities via induction or conduction with an exposed or known surface of the conductive utility.

While on site, GPRS technician James Ross, scanned multiple locations to identify any anomalies that would indicate electrical conduits, water mains, gas lines, and any other pertinent utilities moving through the anticipated path. After further investigation at the suspected site we were able to determine that there were utilities running through the proposed path. Not only could we identify these obstructions, but we also provided accurate depths of each obstruction.
