Ground Penetrating Radar Systems was recently called out to a project Akron, Ohio. The scope of work was to scan several areas in roadways to clear utilities in advance of soil borings. By using GPR and Radio Detection several gas, water, sanitary and unknown lines were located. Had this area not been scanned prior to excavation several lines could have been struck. By having the area scanned beforehand, the client avoided timely delays and expensive repairs. GPRS, Inc. was able to complete the job in a timely manner to mark all utilities in the scanning area. GPR is an accurate and effective way of locating underground utilities, underground storage tanks, and voids.

GPRS recently completed a utility investigation and locate in Dayton, OH on Colonel Glenn Highway. The project that GPRS was working on was being overseen by Star Construction for AT&T. The scope of the project was to scan approximately 1500 lineal feet to locate duct sections between specific manholes along the middle of the highway. Upon arrival GPRS met with Star Construction to walk the length of the proposed path of work to identify any potential hazards.

The main concern that the client had was getting accurate depths to lines within the duct banks, along with a depth to the top of the duct itself. The client needed accurate depths to mitigate any potential damages to the duct. Understanding the importance and accuracy of this, they reached out to GPRS and inquired about the mapping and CAD services we could provide.

After meeting with representatives from Star Construction and walking the site to identify potential hazards, GPRS needed to clarify the engineering controls and PPE to be used to safely complete the work. Being a fairly active highway, traffic controls would need to be provided and full PPE was established to instill maximum visibility while working. Star Construction was able to provide a vehicle to divert traffic away from GPRS as we worked, their help was vital in making sure the project went off without any incident.

GPRS (Ground Penetrating Radar Systems, Inc.) was recently hired by a local contractor during a project where they plan to build a new addition to an existing building. The contractor hired GPRS in order to locate any utilities in the proposed areas where excavation was to take place. The contractor contacted GPRS in order to determine where the existing utilities in these areas were located so they could make any necessary changes and plan accordingly based upon the located utilities. The contractor also planned to intercept certain utilities such as gas and water to tie new services into the existing lines. Once GPRS arrived at the site, our project managers walked the areas of concern (areas to be scanned) based upon a map of the proposed areas the client sent prior to scanning. This was done in order to determine what utilities were present on the surface in the areas being scanned. Upon completing the walk-through of the areas of concern, the project managers first used the EM Pipe Locator and walked the areas to get a general idea of where utilities which contained either an electrical, or communications signal were present. Once this initial phase was completed, the project managers were ready to scan using Ground Penetrating Radar (GPR). The GPR is pushed across the scan boundaries in a grid pattern to identify underground obstructions. The approximate depths of utilities present in the area were confirmed using GPR and marked directly on the surface using spray paint. Utilities such as gas, electric, communication, water, storm, and sanitary were found on this site. In the first image our project manager Josh Domingues is seen using GPR to confirm the approximate depth of the water line that the client had to intercept in order to add an additional service line.

Ground Penetrating Radar Systems was recently called by a local construction engineering firm to help analyze a concrete slab for future construction planning. The contractor needed to know information such as slab thickness, rebar spacing, and conduit presence. The building was extremely old and little information about the slab composition exists. GPRS was able to identify the information the client was looking for as well as mark additional obstructions such as beams and conduits that were not thought to be present. Ground Penetrating Radar Systems was able to identify clear areas where the contractor could safely drill and take a core sample for further testing. The relevant details of the slab were then saved, and a detailed report was handed over to the client with the findings. All this information prevents delays on the project and keeps people safe. Striking a conduit can cost a contractor thousands of dollars in repairs, as well as potentially harming the workers drilling on site. Ground Penetrating Radar Systems, Inc. was able to get to the job in a timely manner which allowed the contractor to stay on schedule. GPRS can also perform after hours services upon request to meet our client’s needs.

Change order! What!? The slab has already been poured, and the customer wants to change the entire layout? Impossible! It’s a Post Tension Cable slab; can’t do it!

Unless you call GPRS! We specialize in identifying Post Tension Cables in the slab and can mark safe places to drill and areas that need to be avoided, so the integrity of the slab is not compromised.

In the picture below, a change order came across the desk of the General Contractor. Planters were now being added to a Post Tension Cable elevated slab. This required over 100 rebar dowels to be drilled 5” into the 8” slab on multiple balconies.

GPRS showed up and completed the job-specific safety training and scanning all in one day. There were over 45 cables encountered in the pathway of the new planters. Now they know both exactly where the cables are located, and how deep the cables are from the top surface of the slab at each encounter.

As it turns out, the surface had recently been waterproofed with a black tar. GPRS normally marks on surface with black permanent marker, crayon, or painter’s tape, but in this case, the marker just blended into the tar. Thankfully, every scanner is a concrete scanner and a utility locator. As utility locators, we carry crates full of paint. A quick trip to the truck, and the location of the Post Tension Cables were clearly painted on the surface.

GPRS (Ground Penetrating Radar Systems, Inc.) was recently hired by a local contractor to scan for any utilities in several areas where they planned to build new cooling towers and expand both ends of an existing building. Prior to our arrival, the contractor indicated the areas to be scanned by marking the four corners of the perimeter in white paint. Once we arrived, we walked the site with the onsite contact and discussed where they planned to excavate inside of the scanning boundary as well as how deep they planned on digging for the new foundations/piping. This was done in order to determine exactly what areas needed scanning and to get an idea of how deep we should scan for utilities, which helps us utilize our time on-site most efficiently. Upon completing the walk-through with the customer, we first used our EM Pipe Locator and walked the proposed area to get an idea of any live communication or electrical signals present within the areas to be scanned. Once we were ready to scan, we set-up and calibrated our 350MHz antenna and GSSI SIR-4000 unit at the area to be excavated and began scanning. During our scanning, we marked all findings on the surface using the appropriate color of paint and flags (where able to). The image below depicts our Toledo/NW Ohio Senior Project Manager, Justin Rasanow, scanning a section within an area requested to be scanned. The remaining two images depict on-site photos of an area that was scanned with the located utilities indicated on the surface. It is important to call GPRS and have each area being excavated scanned with GPR prior to any work being done. In this case, we were able to help the contractor avoid possibly excavating through numerous electrical conduits, as well as existing cathodic protection wires. Upon the completion of our scanning and explanation of our markings to the site contact, the contractor was able to determine where they should dig more cautiously when excavating the area.

Ground Penetrating Radar Systems (GPRS) was recently called out to a project by a construction company to locate private and public utilities for a project on the north end of an active high school. The scope of the project was to locate any and all underground utilities in a 3,500 square foot area prior to trenching for new poles to be placed for overhead lines, and a new electrical line that is being installed underground. By using GPR and Radio Detection, GPRS was able to mark the entire area of all obstructions or impediments in the ground that could become dangerous while trenching. If the contractor had decided against calling GPRS, they potentially would have hit a fiber optic line up to 3 times, and existing electrical twice while trenching to install one new line. GPRS marked all utilities on site with spray paint and pin flags and included specific depths of each line found underground as well. GPR and Radio Detection is an accurate and effective way of locating underground utilities, vaults, tunnels, and other obstructions prior to any ground excavation. This project was a vital first step for the contractor to ensure the safety of all employees, and also helped establish a clearer timeline that avoids stoppages due to utility strike incidents. The scheduling of the project went extremely smooth for all sides, and was performed by one technician for best communication practice.

On September 9, 2019, GPRS was requested to come on site by a general contractor to perform a Ground Penetrating Radar (GPR) scan at a bridge that is being completely remade from scratch high above a set of train tracks. The contractor was looking to see exactly how much concrete coverage was poured over the reinforcement. The contractor needed to know if the bridge was poured correctly to meet standards with at least 2.5” over every piece of reinforcement in place. GPRS found the coverage never met these depths, and the actual depths were far from acceptable. These major problems could severely risk the safety of everyone driving over the bridge in the future. The actual depths were written in black marker on the surface and located every 9-12 feet down the entire 150’ bridge. GPRS was even able to designate the specific depths and test drilled to ensure accuracy to within 1/8”. Without having GPRS on site there could have been serious damage to the bridge in the future. Our work prompted the contractor to begin plans on a major corrective action to ensure safety. Minimizing risks to your employees should always be a top priority of all companies, and GPRS aims to assist in that goal for every client we work for. Before you saw cut or core drill, call GPRS to know what’s underground and in the concrete slab you are working on!

GPRS was recently called out to a project by a general contractor at an RTA facility in Cleveland, Ohio. The scope of work was to locate any underground utilities in the vicinity and in conflict with a new trench that is planned to be installed. The contractor needed to excavate about a 1000ft trench. By using GPR and Radio Detection, we were able to locate utilities that the contactor desired. We were able to locate utilities such as electrical conduits (marked red in picture to the right), within the area of interest, from site lighting poles towards the buildings, and electrical conduits feeding the track switches and traffic control light signals. Electrical conduits were at about 2’ below the surface. Drains were also located.

The most exciting find was a conduit that crossed the trench path, shown in the picture below, that the contractor was unaware of and which would surely have been hit while trenching.

Why dig not knowing where any utilities are when GPRS can locate and mark all utilities with depth indications for your safety!

GPRS (Ground Penetrating Radar Systems Inc.) was hired by Ohio State University (OSU) to locate utilities running through their laser labs, inside their robotic welding and additive manufacturing research building. GPRS was able to locate utilities running through the area, as well as the type of reinforcing within the concrete and the concrete slab thickness.

Pictured below is a GPRS Project Manager scanning in front of Ohio State's new robotic laser welding system, the installation of which would not have been possible without quality ground penetrating radar scans provided by GPRS. This robot will be used for cutting edge robotic welding and additive manufacturing research. The system features a 6- kilowatt laser head equipped with the latest laser beam raster and waveform technology, as well as a wire arc system enabling extremely high productivity hybrid laser-arc welding.

GPRS’s findings changed OSU’s plan regarding placement of the lasers. GPRS was able to highlight possible structural integrity issues as well as locate utilities near the proposed locations. For example, the concrete was reinforced with wire mesh, rather than rebar, which is preferable for such heavy equipment. OSU is now conducting research into how they could increase the structural integrity of the areas where the lasers are due to be placed. Without GPRS, these lasers may have been bolted to inappropriately reinforced concrete.

Ground Penetrating Radar Systems was recently contracted to complete a site investigation prior to the installation of new ground wires in an active substation. The substation was going to be staying active through most of the project and delays due to utility damages or other line-strike issues were a major cause of concern to the General Contractors on site.

GPRS was tasked with locating any underground utility on site such as: electric, drain, and ground grid. We provided the location of each utility with as much accuracy as possible and gave depth where applicable. The technologies used on this project included the standard locating equipment (400 MHz antenna and EM locator.)

Site photos taken of a new utility trench with ground grind located and identified in green, and electrical conduit identified and marked in red. When we arrived on site, we discussed what needed to be done and walked the site. The contact conveyed that their primary objective was to have us locate the ground grid so that they could install new grounding and tie into the existing; we were shown two utility trenches in which this needed to be done. Providing this knowledge to the general contractor let them stay on schedule and prevent any possible injuries from a line strike.

Ground Penetrating Radar Systems was recently called by a local electrician to help assist in the installation of a couple concrete core drilling locations in Columbus, Ohio. The electrician needed to core drill through the slab to install a couple conduits. Ground Penetrating Radar Systems was able to identify clear areas as well as mark and identify reinforcing steel located in the slab. Providing the electrician with as much information as we can directly assists with a safe and speedy project. While we identified multiple obstructions throughout their area of concern, we were also able to tell them an approximate slab thickness. All this information prevents delays on the project and keeps people safe. Striking a conduit can cost a contractor thousands of dollars in repairs, as well as potentially harming the workers drilling on site. Ground Penetrating Radar Systems, Inc. was able to get to the job in a timely manner which allowed the contractor to stay on schedule. Ground penetrating radar is an accurate and effective way of locating conduits, rebar, and post tension cables in a concrete slab.

Below you will find our standard markings for this project, we used sharpie to ensure a lasting deliverable in case of other delays on the project. We were able to identify several open areas for the general contractor to core drill through safely. We believe that all these marks represent possible rebar locations but conveyed to the contractor that these could be possible conduits and to be safe they should stay a minimum of 1”-2” off all our marks. By doing this we can ensure an efficient drilling process by avoiding the steel, beams, and conduits in the slab. This helps keep the project on schedule and prevents any unnecessary injuries that could be caused by striking a conduit with a drill. Since GPRS was able to arrive on site quickly and identify potential hazards in the slab prior to core drilling the general contractor was able to safely and efficiently core through the locations they needed.

Ground Penetrating Radar Systems was recently contracted to complete a site investigation prior to the installation of new equipment at an active compressor pad. The compressor pad was going to be staying active through most of the project and delays due to utility damages or other line-strike issues were a major cause of concern the General Contractors on site.

GPRS was tasked with locating any underground utility on site such as: gas, electric, drain, and possible water lines. We provided the location of each utility with as much accuracy as possible and gave depth where applicable. The technologies used on this project included the standard locating equipment (400 MHz antenna and EM locator).

Site photos taken of what appears to be a wide-open area present in the existing compressor pad. When we arrived on site, we discussed what needed to be done and walked the site. The contact conveyed that this area was where they wanted to set the new equipment and that there wouldn’t be anything running through this area. During our investigation we located the main electrical line and several drains going through this area. Providing this knowledge to the general contractor let them stay on schedule and prevent any possible injuries from a line strike.

GPRS (Ground Penetrating Radar Systems Inc.) was hired by Kraton Polymers to scan in the vicinity of a burst water line inside their Chemical Plant before they excavated to fix it. The initial site contact thought that there was nothing that ran through the area but wanted to be sure by calling GPRS to double check for any utilities and to locate the waterline itself.

GPRS found several lines including water, fire water, storm, fiber, gas, nitrogen, and some unknown lines. We marked all these findings onto the asphalt along with their depths. We also created a map of the area which uses a Google Earth image as a reference map. We overlay all of our findings, which color code utilities by type (as with our spray paint) and have details such as depth and location method. Therefore, if the surface water were to wash away any of our markings, the customer still has a map with all line locations plotted. In the pictures below, a GPRS Project Manager is seen scanning in front of the burst pipe. You can see the color-coded paint sprayed along the surface for utility, resulting in quite a colorful piece of asphalt.

The main tools in our arsenal for utility locating are the 400 MHz GPR Antenna and the Electromagnetic Pipe Locator. GPR works by sending pulses of energy into a material and recording the strength and the time required for the return of the reflected signal. The total depth achieved can be as much as 8 feet or more with this antenna but can vary widely depending on the conductivity of the materials. The Electromagnetic Pipe Locator can detect the electromagnetic fields from live power or radio frequency signals. It can also be used in conjunction with a transmitter to connect directly to accessible metallic pipes, risers, or tracer wires. Depths achieved can be as much as 20 feet depending on the type of signal being traced or methods used.

A General contractor in Cincinnati, OH needed to core a drill hole at a major construction site downtown. Being that the core was for a new fire suppression system, the size of the core would be 10" in diameter. Knowing that this was a Post Tension slab and the risk of hitting a Post Tension cable was high, it needed to be scanned/X-rayed. GPRS, LLC. specializes in this application of work; identifying Post Tension cables and other reinforcement with depths and mapping out directly on the floor to ensure safe drilling locations. In this sensitive project, it is essential to know what is under you before you drill. GPRS, LLC. took the call and was mobilized to the new high-rise project site in downtown Cincinnati.

On Site, GPRS was able to quickly and accurately find the post tensioned cables and steel reinforcement that was within a 10'x10' area where the client wanted his core drilling location to be. Typically, when A client needs a core drilling location cleared, a 2'x2' area is scanned. In this situation, the core was much larger and the client asked if a larger area could be scanned. GPRS was able to do this with no hesitation. At a client's request; larger areas may be scanned, especially if there is a lot of room for adjustment with the core location. All findings within this area were marked directly on the surface along with depths. GPRS was able to then discuss the findings with the General contractor. Locations of the post tension cables/steel reinforcement, depths, and slab thickness were all deliberated to find a safe drilling location for the future fires suppression system. This project was a success, and GPRS was able to ensure the security of the structural integrity, along with the safety of others while work was performed.

GPRS (Ground Penetrating Radar Systems Inc.) was hired by Ohio State University (OSU) to locate utilities running through their laser labs, inside their robotic welding and additive manufacturing research building. GPRS was able to locate utilities running through the area, as well as the type of reinforcing within the concrete and the concrete slab thickness.

Ground Penetrating Radar Systems was recently called by a local environmental firm to help assist in locating existing radiant heating tubes in the slab prior to core drilling in Cincinnati, Ohio. The contractor needed to core drill through the slab to install railings. Ground Penetrating Radar Systems, Inc. was able to arrive on site in a quick manor and begin assisting the contractor with their needs which allowed the project to stay on schedule. The contractor conveyed that we needed to utilize crayon on this project to convey our findings but not permanently mark the slab. We also clearly marked scan boundaries using red crayon to accurately showcase the limits of ours scans. GPR is an accurate and effective way of locating conduits, rebar, and post tension cables in a concrete slab.

GPRS (Ground Penetrating Radar Systems Inc.) was hired by Midcity Electric to mark out 12 core drilling locations on a pan decking slab, spread over two floors of the AEP high-rise office building in downtown Columbus, Ohio. GPRS marked highs and lows of the metal pan decking, as well as any conduits running through the concrete. We then recommended to the customer to drill through the highs of the pan decking, as we are better able to confirm the absence of conduits in the high portion of the metal sheets. The last picture below shows what pan decking looks like prior to having concrete poured over the top.

GPRS marked all the highs and lows and found several conduits. Furthermore, to the surprise of the customer, we also discovered that many of the locations of pan decking the customer had intended to drill into had beams running below it. Below are two examples of where we found beams running in both directions along the bottom of the concrete slab. Many of the core drilling locations had to be moved to prevent drilling into one of these foundational supporting structures.

The main tools in our arsenal for concrete scanning are the 1600 MHz GPR Antenna, the 2000 MHz GPR Antenna, and the Electromagnetic Pipe Locator. One of the benefits of calling GPRS for any concrete scanning or utility locating job is that we are specially trained in more than one method and utilize several different pieces of equipment to ensure our customers receive the most thorough and all-encompassing methodologies to perform our jobs to the highest standards possible.

The highly anticipated Sonic Temple Art and Music Festival, located at Mapfre Stadium in Columbus, Ohio, featured a lineup led by multiplatinum artists: Foo Fighters, System Of A Down and Disturbed. During the preparation for the festival, Columbus Crew hired GPRS (Ground Penetrating Radar Systems Inc.) to find and locate all underground utilities in the surrounding areas and stadium parking lots. This was scheduled prior to teams moving in to drill holes into the ground in various locations for tent and fence posts.

GPRS located and marked gas lines, water lines, fire-water lines, site lighting, communication lines, and storm lines. We ensured no utilities were struck. To locate all the utilities we used two methods, each of which is preferable at finding certain utilities. When utilized in conjunction, they ensure a much more thorough utility locate than using one method alone. This is one of the benefits of calling GPRS for any utility locate or concrete scan; we are specially trained in more than one method to ensure our customers receive the most thorough and all-encompassing methodologies to perform our jobs to the highest standards possible.

GPRS was recently hired by a local contractor to scan a 10” thick, elevated slab in an equipment building at a local water treatment plant. Prior to our arrival, the contractor determined that there were four possible locations he wanted us to scan in order to run conduit through the slab to the floor below. The contractor planned to core three 2” diameter holes in each of the four locations scanned in order to run conduit to new equipment being installed on the floor below. Once we arrived, we walked the site where the proposed coring locations would take place in order to get an idea of what type of slab we would be scanning as well as if any visible conduits were going into the slab areas being scanned.

We also went to the floor below and above the floor being scanned to determine if the slabs were consistent on each floor. Once we were ready to scan, indicated the perimeter of the area being scanned using dash marks. We then set-up and calibrated our 1600MHz antenna and GSSI SIR-4000 unit at each of the four proposed areas and began scanning. During our scanning, we marked all findings on the surface using permanent marker or crayon per customer request. The image to the right depicts our Toledo/NW Ohio Project Manager, Justin Rasanow, scanning one of the four proposed locations requested by the contractor. The remaining two images depict on-site photos of areas that have been scanned with the anomalies and scanning boundary indicated on the surface. The markings with diagonal lines running through them indicate anomalies with characteristics of rebar. The wider markings with an “X” running through them indicate anomalies with characteristics of conduit.

Ground Penetrating Radar Systems (GPRS) was requested to come on site by a general contractor to perform a Ground Penetrating Radar (GPR) investigation at a hospital that is preparing to have a brand new room put inside of the west wing of the building on the ground floor. The contractor is needing to saw cut several trenches to install new drain lines and electrical/communication conduits running through the renovation area. The contractor needed to know if there were any conduits or potential problematic areas to avoid when saw cutting through the concrete. These major problems could severely risk the safety of employees if not found prior to using a saw. GPRS located multiple electrical conduits that were in, and just below, the concrete slab that could have been easily saw cut through if the blade were set too deep by the worker performing the cutting. The conduits were marked on the surface with red spray paint, and also included depth indications so that the contractor could safely saw cut over or around them without hitting the conduits.

Also, just to be even more specific for the contractor, conduits that were found to be live were marked with solid edges on the surface, and conduits that were found to be cut off and abandoned were marked with dashed lines. All conduits should be avoided at all times regardless, but this gives even more notice for the contractor to be aware of findings and have an even higher comfort level when beginning saw cutting. GPRS also was able to locate a majority of the drain lines running under the slab as well and marked those with green spray paint to make sure the general contractor knows how to differentiate between findings.

Ground Penetrating Radar Systems Ohio (GPRS Ohio) was recently called out to a project by an environmental company to locate utilities for a project on a 60+ acre lot inside of an active coal mine. The scope of the project was to locate any and all underground utilities for almost 50 soil boring sample locations to be drilled down 25+ feet. By using GPR and Radio Detection, GPRS was able to safely clear each specific location of any obstructions or impediments in the ground that could become dangerous while drilling. GPRS painted all utilities on site with spray paint and included depths of the lines found underground as well. GPR and Radio Detection is an accurate and effective way of locating underground utilities, vaults, tunnels, and other obstructions prior to any ground excavation. This project was a vital first step for the environmental company to ensure the safety of all employees, and also helped establish a clearer timeline that avoids stoppages due to utility strike incidents. The scheduling of the project went extremely smooth for all sides, and was performed by one technician for simplicity and best communication practice as well. Why would you risk digging underground without knowing where any utilities are in your designated area when GPRS has the ability locate and mark all utilities with depth indications for your safety!

GPRS recently completed a private utility locate at CVG International Airport in Hebron, KY. The scope of the project consisted of the addition and removal of entrance ramps from a highway, and the building of a new parking garage (designed to hold rental car companies much closer to the main terminal). When contacting us about this project, the contractor stated that they needed to determine as much of the underground infrastructure as possible due to this being an “exploratory option”, to determine if they would be able to continue with certain designs and plans previously engineered. They had a set of original blueprints from when the airport was designed but didn’t know anything about what underground infrastructure was still there, what had been removed, and exactly what had been installed from the get go etc.

Ground Penetrating Radar Systems (GPRS) was requested on site by a general contractor to perform a Ground Penetrating Radar (GPR) survey. The contractor needed to saw cut a trench to install new sanitary lines to replace the existing sanitary. The contractor needed to know if there were any conduits in the area to avoid saw cutting through them. GPRS located a bank of live electrical conduits that were just below the concrete slab at 5” depth that would have been saw cut. The conduits were painted on the surface with depth indications so that the contractor could safely saw cut over or around them without hitting the conduits. The site had knowledge of the electrical conduits found, and were glad to confirm their location. Without GPRS on site there could have been serious damage to the electrical lines.

Ground Penetrating Radar Systems was recently called to a project at an IBM office building by a local construction company in Columbus, Ohio. The scope of work was to scan several sections of an asphalt parking lot, locating and mapping out underground utility lines before excavating to repair drain lines. There were several utility lines that were marked out using GPR that would have been struck during excavating. GPRS, LLC. was able to get to the job in a timely matter to map out the utilities so the project could stay on time. GPR is an accurate and effective way of locating underground utility lines, underground storage tanks, and voids.
