Private Utility Locate at Power Plant – Crystal River, FL


Ground Penetrating Radar Systems, Inc. (GPRS) was contacted by a construction company in order to locate utilities at a power plant in Crystal River, FL. The construction company needed utilities located, marked out on the surface with paint, flags, and a depth. After marking out all utilities, the contractor needed all findings put into a cad map file for the company to have on file. The contractor contacted GPRS of Tampa to perform the GPR and GPS mapping needed for this project. The contractor needed this project completed in order to be able to expand their operations area.

A GPRS technician was contacted in order to perform the survey at this location. Using our 400MHz antenna and RD7000 radar equipment, we scanned each area of concern. We were able to map out all needed buried utilities. All located utilities were marked with paint, flags and a depth to the top of the anomaly directly on the surface. After all areas of concern were located and marked out, the findings were clearly relayed to the onsite contact. The contractor was pleased with our results and felt relieved to know where the utilities were located, and at what depth each utility was prior to excavating.

Upon arriving onsite, the technician met with the contractor and went over the areas of concern that needed utilities located. Each area was scanned in a north/south, east/west pattern with the RD7000 for any power or communications. The GPR 400MHz antenna was used to scan each area in a north/south, east/west pattern to locate the exact location and depth of the utility. All located utilities were marked out with paint, flags and a depth. Each utility was color coded accordingly. Red-power, Orange-communications, Blue-water, Yellow-gas, Green-storm/sewer, White-unknown utility. We used our Trimble Global Positioning System, (GPS) technology to locate the coordinates of each located utility. We then took this information and put it on a cad map file for the contractor.

GPR Scan Performed to Locate Live Conduits in Newark, NJ

Ground Penetrating Radar Systems, Inc. – GPRS – of Northern New Jersey was contacted by a general contractor to locate all pipes and live conduits within and under a slab on grade in order to install a new sanitary line within an educational hospital.  The general contractor was planning on saw cutting the slab and digging down 3 feet in order to install a new sanitary line.  To ensure safe cutting and digging, the client requested all pipes and conduits within 3’ to be located.  The entire trenching area was scanned and any obstruction was located and marked out in real time.  Multiple live conduits were located both embedded in the slab and under the slab within the trenching area.  The contractor was able to cut shortly after the scanning was completed and the collaborative efforts and real time results helped keep the job on schedule.

GPR & Radio Detection used to Locate Conduits in a Slab at a School in Ann Arbor, MI Prior to Saw Cutting

GPR & Radio Detection

A lot of times in older schools, electricians placed conduits in the pour of the concrete. It’s always hard to know the actual paths of the conduits 20-30 years after. There is technology such as ground penetrating radar & radio detection that can help identify where the conduits were placed. It is always good practice to have the floors scanned prior to any saw cutting to ensure existing utilities don’t get compromised.

In this situation, a general contractor began to saw cut the floors without having GPR & radio detection utilized. Once they began the saw cutting, numerous conduits were struck immediately. GPRS of Michigan was contacted by the general contractor to investigate the concrete floors before saw cutting any further. Once notified of the situation, GPRS was able to mobilize to the site the following day. They used a high resolution concrete antenna along with a radio detection device to scan the rest of the proposed saw cutting areas. As you can see from the photos it was a great idea for the general contractor to contact GPRS to scan the floors going forward. Numerous conduits were marked directly on the surface with the depths provided. It would’ve have taken days to figure out the paths of where the conduits ran to if they were cut & had to be replaced. Plus, the school was still in session so there would’ve been some power knocked out that was feeding the classrooms. The GPRS technician walked the site contact around to ensure everyone was on the same page with what had been located. In the future the general contractor mentioned they will no longer saw cut without having the floors scanned prior.

GPR & Radio Detection-2

Ground Penetrating Radar & Radio Detection are both great methods to locate underground utilities, sub-surface voids, conduits, reinforcing steel, etc. If you would like more information regarding the capabilities of GPRS, please contact Regional Manager of Michigan, Thaddeus Bullock, at 734.377.4551 or You can also visit the website at

GPR Concrete Scanning – Atlanta, GA

GPR Concrete Scanning – Atlanta, Georgia – February 2017

Ground Penetrating Radar Systems, Inc. (GPRS) was contacted to perform a GPR survey at a high rise building in Atlanta, GA. GPRS was asked to determine the location of reinforcing, conduits, or any other potential obstructions prior to core drilling in multiple locations.

Ryan Abueg was the technician from GPRS that arrived on site to complete this project. Prior to arriving on site, the locations had been laid out using the pink “X’s” that can be seen in the photos. Using the 1600MHz GPR antenna, any anomalies that were found were marked directly on the surface using a black marker. Once each location was surveyed, the findings were then explained to the contractor in order to develop a safe plan for the drilling.

The photos included depicts the final markup of two of the areas of concern that was brought up by the contractor onsite. As mentioned before, the proposed core locations were laid out prior to GPRS arriving on site. If these areas were cored before they were surveyed, there may have been serious damage done to the structure. GPRS recommends that a GPR survey be performed prior to any cutting or drilling be performed.

GPR Concrete Scanning – Atlanta, Georgia – February 2017-2

GPR is a safe alternative to a costly repair to conduits or post tension cables damaged by drilling. GPR emits no radiation and poses no health hazards. Any findings are marked in real time directly onto the surface with no processing time which allows the contractor to begin drilling immediately after a survey. GPR is frequently used to scan the ground to determine location of underground utilities and underground storage tanks as well.
