GPRS was contacted by a local construction company to scan for suspect radiant heat tubing at a new Tesla facility near Chicago, Illinois. The contractor needed to find the heat tubing in order to safely remove the metal sheath around the existing vehicle lifts future building projects.

GPRS also scanned several areas for the electricians on site in order for them to safely dig a trench for new underground electric lines for the Tesla charging stations. GPRS was able to pair thermal imaging and GPR technologies in order to locate the heat tubing for a safer dig and saw cutting.

The thermal camera we use can detect changes in temperature as small as <0.1°C with accuracy with 2°C. When the system is heated near to or after the start of the project there is a contrast between the temperature of the tubing and the concrete slab.

It’s no mystery that drilling for environmental samples comes with certain risks. Overhead power lines, above ground obstacles like crowded parking lots, and, perhaps most challenging of all, underground utilities.

Drillers, geotechs, and environmental firms alike know this particular challenge full well. Because of this, robust damage prevention plans are created in attempt to eliminate line strikes and other hazards associated with drilling for samples. Various best practices are considered, implemented, and refined as experience dictates.

Construction teams and engineers must work hand in hand to make sure that buildings and structures go up in a safe yet timely manner. In Orlando, there is an array of amusement parks, resorts, hotels and a so on. Currently everything seems to be growing which is great for business, but it also means that sometimes, we must be even more careful when making changes to plans

A construction team at one of these amusement parks was handed down an alteration that needed to take place to account for an addition they had not initially planned on. Basically, they needed to drill for anchors into a structural column to add some metal plates. They needed to make sure they abided by the requests for the changes without undermining the integrity of the structural steel. Being well acquainted with Ground Penetrating Radar Systems the supervisor reached out to them and had them come out to scan for the structural steel (rebar) prior to drilling.

After arriving on site, the construction team had already had a boom lift brought into the area so that the GPRS professional could access...

Ground Penetrating Radar Systems, LLC. (GPRS) was contracted to locate everything in a concrete slab at a parking garage, located in West Palm Beach, Florida. The contractor had no idea what was in this slab where they wanted to core due to the fact that the post tension plans are not 100% accurate. GPRS was hired to mark all findings in order for them to core drill so the local electricians could run electrical lines through the slab. With the amount of structural steel and post tension within a slab it is not easy to find a good place to core through a slab without compromising the strength of the structure. Reference the picture below.

A valued customer recently requested that we map out all post tension cables in an Orlando area resort. There were four areas, each about 500-1000 square feet, that needed to be mapped out, with both the post tension cables and the conduit marked. We were asked to paint the PT cables red and the conduit blue in order to distinguish between the two.

The customer had photos of the area prior to the concrete pour, so we were able to compare our field markings to photograph, and we thought the results were worth sharing. Not every job allows for such a stark visual confirmation of our findings, but in this case, the customer’s photo demonstrated the clarity and accuracy of our marks.

Note: There was a piece of conduit in the photograph that was not in our field markings. We confirmed that this conduit had, in fact, been removed prior to the pour.

The conduit was easy to distinguish from rebar in this particular slab because it was empty and thus created a negative reaction—the metal rebar reflects the GPR signal back to the receiver, whereas the air inside empty...

GPRS of Florida received a call from a new customer who had recently hired one of our competitors to scan an area prior to the installation of several plumbing lines. Our customer was concerned that the scanning service that they had used made several mistakes, and several items had been missed. After the customer called GPRS, we offered to only charge them for the project if we were able to offer them new, and relevant information.

After getting started with the scan, it became immediately clear to us that our competitor made several mistakes. In the image above, you can see several of the markings that GPRS marked onto the surface (in black). You can also see our competitor’s markings (in red crayon). Our competitor had missed the fact that one of the lines ran at a slight diagonal (at about a 15º angle). Our competitor had marked the line as through it were straight, and as a result, their markings were off by up to 4”.

As we completed this project, it became clear to us that our competitor had likely rushed the scanning process, as there were several obvious...

It can be hard to foresee all situations and plan accordingly for each scenario when constructing new buildings. Subcontractors come and go and you can’t always keep an eye on what every person does on a job site. A plumbing contractor had installed the necessary plumbing lines and also installed clean-outs for future lines to be installed at a new warehouse in Orlando, FL. Little to their knowledge that after they installed everything the concrete team cover the clean-outs and poured concrete over them. The problem was that there was no way of them knowing where the clean-outs would be for future use. They had a good idea of where they were but finding multiple clean-outs in a large warehouse can be like finding a needle in a haystack.

Fortunately, for this team they knew about Ground Penetrating Radar Systems. GPRS is a team of professionals that specializes in locating subsurface elements. This was a unique project for the Orlando team, but when it comes to problem solving GPRS shines. After a few conversations, it was decided that we could help their team find a...

The Fort Lauderdale Airport has been making countless changes in recent years, as a result they’ve had Ground Penetrating Radar out there sporadically working alongside them in different projects. Recently, they were tasked with adding multiple steel plates to several beams. Normally, this would not be such a complicated job because the beams would not be filled with too many rebars that could hinder them from finding their coring locations. However, things were very different this time around and a bit problematic because, each time they drilled, they’d hit multiple rebars.

In light of that, in an effort to avoid wasting their time guessing where to drill and to avoid damaging the beams, the crew at Fort Lauderdale Airport decided to call out Ground’s Penetrating Radar to help them locate all of the rebars. We were happy to lend our services and demonstrate our expertise in concrete scanning. They knew that with our technology we could successfully identify and mark all of the rebars for them, thus providing them with an efficient way to complete their work and ensure...

GPRS was called out to scan for private utilities at a wastewater treatment plant near the quad cities in Iowa. The engineers on this project were not only concerned with where each utility was but also interested in mapping the features and including depths of each utilities. GPRS was able to come out with only a day notice and do just that!

Scan before you plan! This ensures worker safety and saves valuable time by targeting specific areas of concern. GPRS was able to provide a GPS report overlaid on Google Earth and an overlay on a pre-existing CAD file for the future building plans at this site.

GPRS was contacted by a engineering firm to investigate for any buried structures or possible underground storage tanks (USTs). After arriving on site, the firm let GPRS know that there had been a truck stop with diesel filling stations at one point dating back all the way to the late 40’s or early 50’s.

There was no clear documentation stating whether the USTs had been removed or abandoned in place, so GPRS did what we do best; create a strategy to provide the best subsurface scanning solution.

GPRS scanned the area with Electromagnetic Induction (EMI) equipment, and we were able to provide conductivity maps that represented the data collected from the scanning process and overlaid on to Google Earth. GPRS also provided a detailed report which included maps of any utilities around the area as well as where the suspect tanks were to be. Data screenshots were saved for the reporting as well.

The Chicagoland area is filled every year for the summer festivals, food, music, and fun. With so much entertainment available, it is commonplace to see contractors setting up structures and other festival related items, seemingly daily. The skilled contractors whom perform these tasks can make it seem like an easy and often occurring task. But it is worth noting, that these professionals would likely spend time preparing and planning in order to perform these setups safely and efficiently.

An important tool in any contractor or installer toolbox, is the utilization of locating procedures by GPRS. GPRS provides critical information regarding the location of utilities which can be beneficial to the design, installation, and site safety for each jobsite. Additionally, the information GPRS provides can aid in lessening the delays, costly repairs or downtime, and safety risks which occur when utilities are struck. In addition to markings on-site, GPRS can quickly produce GPS maps and CAD drawings from the findings which communicate utility locations to stake holders and assist...

There is a lot happening in Tampa right now, and we have recently expanded our North Florida team to stay ahead of the demand. We believe that scheduling GPR should be simple. You should trust the team you call. You should know that they have your best interest in mind. Scheduling an appointment should be quick, and you shouldn’t have to wait a week to receive service. Every project manager should arrive on time and be friendly, qualified, and dedicated to your project. He should make clear markings, explain what they mean, and his results should be industry leading in their accuracy. We believe that our Tampa customers deserve our above and beyond, standard. Everything we do is a reflection of these beliefs.

We recently got a call from a new customer in the Tampa area and we were able to mobilize a project manager the next day. Nate used a high frequency GPR antenna to scan for anomalies in and directly below the slab, and then he used a low frequency antenna to scan for utilities deeper down. Finally, he swept the scan are with our EM technology to detect...
