Ground Penetrating Radar Systems’ Jacksonville Florida office was recently contacted to locate utilities near downtown Jacksonville. The client was working on a property near the Riverwalk area and was installing new communication lines. They wanted to avoid damaging any utilities running to the number of restaurants and condo buildings along the south side of the St. Johns River so GPRS was contracted to complete private utility locates. The proposed trench and directional bore path was scanned using GPR and radio detection devices. All utilities were painted and flagged directly on the ground surfaces. Following the investigation all of the findings were collected using a GPS Trimble device to collect the locations of each of the items. Water, gas, electrical, conduit, communication, fiber optics, natural gas and other unknown utilities were all found in the area. Each location was collected and placed into an aerial map and later inserted into a CAD file.
The client was able to use the markings in the field and the mapping services following the investigation to safely and timely install the new utilities and avoid damaging any live utilities already in operation.

In the image below you can see GPRS technician Adam Yunker scanning with his 400 MHz antenna along the Riverwalk area in downtown Jacksonville.
Ground Penetrating Radar Systems, Inc. was contacted by a contractor that needed to know the location of utilities prior to excavation earlier this month. The client’s primary concern was to identify any utilities or other subsurface items within the excavation area prior to digging so they could take appropriate measures in either relocating the utility or their excavation area. The project consisted of clearing three 20’ X 20’ areas to allow them to excavate down 25’ and tie into an existing walkway tunnel. Utilizing the latest in GPR technology and Radio Detection, Joe Bernarducci of the New York City Office of GPRS responded to the site and was able to mark out several utilities traveling through the proposed areas. With the utilization of GPR on this project it gave the client a way to identify any utilities or other subsurface obstructions in the area in a nondestructive, safe manner. All of the utilities that were located were then marked directly onto the service in real time while GPRS was on site. The use of ground penetrating radar allowed the client to stay safe while digging and helped to keep them on their tight completion schedule. With the professional services provided by GPRS, no utilities were struck during the excavation of the three areas allowing the client to stay safe on this project.

Ground Penetrating Radar Systems, Inc. (GPRS) was contracted to locate everything in a concrete slab at The University of Utah hospital, located in Salt Lake City, Utah. The contractor had no idea what was in this slab due to the fact that it was over 50 years old. GPRS was hired to mark all findings in order for them to core drill for remodeling. Recently, The University of Utah made the smart decision to make this mandatory due to the lack of knowledge about the slabs and wanting to ensure safety.
Ground Penetrating Radar Systems, Inc. has a few different tools that could be used to locate, potentially anything, within a concrete slab. GPRS used the 1600MHz antenna on this project; the 1600 is our standard piece of equipment. We also used a smaller antenna called “The Palm”, this antenna helps us get into smaller areas and allows us to get to areas that are just too tight for the larger 1600MHz antenna. Finally, GPRS always has a Radio Detection wand handy for all jobs. The Radio Detection wand is a way to double check that there is no power running through the slab.
At the University of Utah hospital, we were able to locate all the reinforcement within the slab so that they could core drill safely. The University was glad that they did not have to clear out the area, like they would have to have done if they used x-ray. This University hospital could not have the area cleared out, but wanted to make sure that the work was done safely as well. GPRS was able to ensure that both were done. Radar is safe to be around, and the job was done without the core driller hitting anything within the slab.
GPRS does much more than concrete scanning. We also do utility locating, underground storage tank (UST) locating, and we can even find voids. If you need work done safely, it is our job to make sure you don’t hit anything while drilling, cutting or digging. If you need work done in Utah, Idaho, Montana or Wyoming, please Contact Cooper Cox, Project Manager at (801) 419-7031 or firstname.lastname@example.org
Opening in 1933, the Hoover Dam has been one of America’s most iconic landmarks for over 80 years. This dam not only helps form Lake Mead, the largest reservoir in the world, but it also is a great source for hydroelectric power in the southwest. Without it, cities like Los Angeles, Las Vegas, and Phoenix would most likely not be the thriving metropolis’ they are today. Due to the dam’s age and incredible importance in keeping the west watered, some upgrades were inevitably going to be needed. Recently, a company who was hired to take care of some of these routine maintenance issues needed concrete scanning done.
Ground Penetrating Radar Systems was called to scan multiple areas prior to drilling into the concrete for anchor bolts for the extremely heavy equipment that was going to be installed. The scanning done by GPRS allowed the customer to confidently drill without hitting the reinforcement in the 30 inch concrete slabs. GPRS used a 1600 mHz antenna with the ground penetrating radar to scan the areas. All of the findings were clearly marked on the surface with permanent marker and discussed with the customer before drilling began. Had they not wanted permanent markings, GPRS is always ready to mark findings on concrete using crayon or tape instead. Whether working on an older historic landmark, or a freshly built hospital and everything inbetween, Ground Penetrating Radar Systems can help.
Prior to saw cutting, core drilling, excavating or boring in the Las Vegas and Southern Nevada areas, be safe & get as many questions answered as to what sub-surface obstructions are present. Pretty much, if you have questions about what lies beneath whatever surface you’re working on, GPRS should be able to give you a much clearer picture as to what you are dealing with. Typically able to arrive on site to begin scanning within 1-2 days, GPRS will take care of your project in a timely, safe, and accurate manner.

The GPRS East Tennessee office was subcontracted by an engineering firm out of Knoxville, TN to scan approximately 1.5 acres in Knoxville, TN at University of Tennessee Medical Center. The firm was interested in collecting soil samples for analysis. UT Medical Center was interested in expanding their chiller capacity, which is currently stationed on a roof top. There were 6 locations that needed to be scanned in the rear parking lot with ground penetrating radar so that underground utilities would not be struck when the drilling took place. The GPRS representative used a GSSI 400 MHz antenna and a radio detection wand to scan these 6 locations over multiple surfaces and terrain conditions. Each location to be drilled was scanned in a 10’x10’ radius, and bordered with white paint on the surface so the drilling contractors could better understand the exact boundaries of each area scanned with ground penetrating radar. There were multiple utilities and areas of interest found on this site, and upon location, each utility and area of interest was marked on the surface with paint indicating what type of utility was encountered. Depths were provided if located with ground penetrating radar. All findings were reviewed with the site contact after the ground penetrating radar inspection and any locations that had to be moved due to utilities in the direct path were communicated with the site contact. Details of the inspection were also reviewed with onsite personnel so that they could update their site drawings for their records.
The 400 MHz transmits an electromagnetic pulse through the ground and displays the reflection on a SIR 3000 head unit for interpretation. This antenna allows for ground penetrating radar signal penetration of 4’-7’ through the ground in the southeast region of the United States. Radio Detection RD-7000 locator is a device that 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 ground penetrating radar. It also allows us to detect utilities via frequency induction or conduction with an exposed or known surface of the conductive utility.

Ground Penetrating Radar Systems was recently called out to a project in Lyndhurst, Ohio. The scope of work was to locate any underground utilities throughout the roadway from the main entrance to the main building. By using GPR and Radio Detection, many utilities were located with depth indications to prevent utilities from getting hit. The contractor needed to put in a new roadway and needed to know what utilities were in the area. Electrical conduits would have been hit during excavation if they were not marked with depth indications. GPR and Radio Detection is an accurate and effective way of locating underground utilities, underground storage tanks, and voids. The pictures below show some of the many utilities located on site.
