GPRS was recently contacted by a large energy corporation to locate underground utilities at one of their new wind projects in Oklahoma. The work consisted of using radio detection and ground penetrating radar to locate and mark out utilities that were along the collection lines, transmission lines, and turbine sites on the wind farm. Andy Dermer – GPRS Oklahoma – performed the work by scanning the designated areas and marking the locations of utilities directly on the ground with marking paint, pin flags, and wooden stakes. These findings were also recorded to be used in a Google Earth file for future reference. With renewable energy on the rise, Ground Penetrating Radar can be an invaluable tool to help keep the site safe. Due to the instantaneous results GPRS can provide, the information is immediately available to prevent accidents or injury on the job site.
“GPRS has done another outstanding job providing subsurface engineering work across Northern Oklahoma locating several pipelines that had been otherwise forgotten about over the years, and providing the crews a peace of mind that they can dig safely. The GPRS team has shown dedication to their craft, an impressive work ethic while operating in harsh conditions and most importantly displaying exceptional communications skills that are vital to building a successful windfarm.”

Ground Penetrating Radar Systems of Virginia was utilized to detect underground utilities at a construction site in Glen Allen, VA. The as-built plans were inaccurate and the customer needed a particular fire-water line located. GPRS Project Manager Josiah Donaldson verified the location, depth, and direction of the 30 year old+ water line at approximately 5’ deep. As a result, the customer updated the as-built plans and successfully avoided expensive pot-holing and searching for the lost utility.

Ground Penetrating Radar Systems, Inc. – GPRS – of Southern California was contacted by an HVAC company in order to mark out the rebar in a ceiling prior to coring an 8” hole for a new AC unit. We found that the slab was 6” thick and the rebar was 12” on center. We had to scan the area from the bottom as the floor above us was occupied with office desk/portables. The client wanted to preserve as much rebar as possible due to the building’s being considered a historical landmark so we marked out a 5’x5’ area and provided the customer with several coring options.
GPR mapping is a great tool to scan for post tension cables, rebar, and conduits; it can also be used to locate underground utilities prior to digging or excavating. GPRS has offices throughout the entire state of California and performs projects in cities like Ventura, Santa Barbara, Thousand Oaks, San Luis Obispo, Bakersfield, Lancaster and the greater Los Angeles area. Please contact Freddy Espinal at 805-729-5877 or firstname.lastname@example.org to learn more about ground penetrating radar and how GPRS can assist in your projects.

Ground Penetrating Radar Systems (GPRS) was contacted to locate post tension cables that were present in the concrete slab prior to saw cutting using Ground Penetrating Radar (GPR). Curtis Hoag, Regional Manager in Charlotte, NC used the GSSI (Geophysical Survey Systems, Inc.) 1600 MHz antenna to locate the reinforcing steel and mark out the grid pattern for the cables on the surface of the concrete. This enabled the customer to avoid hitting any post tension cables or other unknown subsurface anomalies prior to saw cutting for electrical lines and plumbing.

Ground Penetrating Radar Systems was able to respond immediately to perform the work that required locating all reinforcing steel in the slab prior to drilling. The local construction company was contacted to install tie down locations on the rooftop to allow future work to be done safely. The project was undertaken in Colorado Springs Colorado and local technician Shawn Selmeski was able to facilitate in the project. Over twenty locations on the rooftop were scanned and anchors were placed with no interference with the reinforcing in the rooftop slab.
GPRS is available to locate reinforcements in a concrete slab, whether it’s post tension cables or rebar. Locating conduits and utilities also fall under the abilities of our technicians.

Prior to selling or developing properties, the parties involved need to determine if any underground storage tanks are still present on the site. Nobody wants to be stuck with the cost & headache of removing any unknown underground storage tanks with a property they just purchased. Ground Penetrating Radar is an excellent tool to utilize when determining if any UST’s are still present at a site.
An Environmental Company had a project at an former police station in Detroit MI where they were asked to determine if any underground storage tanks were present on the property prior to developing the land. There weren’t any records confirming or denying if any UST’s were still present on the property. Ground Penetrating Radar Systems of Michigan was contacted to investigate the parcel to provide answers to some of the questions regarding remaining UST’s onsite. GPRS utilized a 400 MHz antenna to investigate the areas. The technology used provided real time results for everyone involved. During the investigation GPRS identified a couple of possible areas where an underground storage tank could still be present. They were able to communicate the suspect areas to the environmental company for further investigation.
The next time you have a need to locate sub-surface objects in Michigan, contact Regional Manager, Thaddeus Bullock at 734.377.4551 or Thaddeus.email@example.com. GPRS also utilizes a high resolution concrete antenna to locate embedded conduits, reinforcing steel, voids, etc. Please contact Thaddeus Bullock or visit our website at www.gp-radar.com for a complete listing of our national locations.
Ground Penetrating Radar Systems in Minnesota was contacted to determine the locations of private utilities at a cell tower site in Shakopee, MN. Troy Bartlett, Project Manager with GPRS, used electro- magnetic induction to locate electric and communication lines present within the surrounding area and ground penetrating radar to mark conduit locations and verify trenches of utilities marked by One-Call locators.
Damaging any one of the “High Profile” utilities located at this site has the potential to disrupt service to thousands of customers including emergency personnel and government agencies in the area. The contractor involved in excavating for new services within the compound trusts GPRS to protect their crew and reputation from costly damages.
In March of 2016, Ground Penetrating Radar Systems, Inc. (GPRS) was contacted by an energy company to locate utilities such as electric, water lines, communication lines, gas lines and any other utilities in Bartow, FL. The company needed to know where these anomalies were running in order to dig a trench to install new water chiller lines. The company contacted GPRS of Tampa, Florida to locate all of the utility lines to avoid hitting any of them.
Isaiah Runkle of GPRS was contacted to perform the survey at this location. Using our 400MHz antenna radar equipment, we were able to map out the utilities which were running through the areas of concern as well as provide depths to the tops of the anomalies found. The contractor was pleased with our results and felt relieved that they were able to work in the areas knowing where the utilities and other anomalies were located. Below is a photo taken on-site which depicts Isaiah locating utilities running through the area of concern.
