Locating Utilities for an Environmental Contractor - Little Rock, AR

Zach Bates, a project manager for Ground Penetrating Radar Systems, LLC. in Little Rock, Arkansas, worked with an environmental contractor to locate underground utilities prior to excavating at a vanadium plant in Hot Springs, Arkansas. GPRS, LLC. utilized a GSSI 400 MHz ground penetrating radar antenna as well as a Radiodetection RD7000+ to locate electrical, natural gas and water lines on the property. The utilities were marked with marking paint and flags.

Private Utility Locating Project at Cell Tower – Little Rock, AR

Private Utility Locating - Little Rock, AR  
unknown utility locating project

Ground Penetrating Radar Systems was recently contacted by a general contractor to locate and map all underground utilities, as well any underground anomalies at their site in Little Rock, AR prior to excavating on site prior to adding new addition to cell tower.

GPRS used the latest ground penetrating technology to provide relevant information about critical utilities, and other potentially dangerous, and problematic areas underground while on site. The equipment used for this scan included:

• GSSI Ground Penetrating Radar/ SIR 3000 – 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 Project Manager, Ethan King, scanned approximately 1 acre around cell tower to identify any anomalies that would indicate electrical conduits, water mains, gas lines, and any other pertinent utilities moving through the customers anticipated excavating locations. After further investigation at the suspected site we were able to determine that there were underground utilities running through the proposed drilling zones such as electric conduit and ground lines. GPR located data cables outside of the area of concern. GPRS plotted the locations of subsurface obstructions directly onto the surface, and provided accurate depths giving the contractor a clear indication of where it was safe to excavate, as well as where extra caution would be necessary. Not only did we ensure the safety of the crew by identifying potential life threatening hazards, but also eliminated any potential costly repairs that may have been added to their project due to damaging unknown utilities.
