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.

Prior to saw cutting concrete floor slabs, it’s essential to have as much information as possible in regards to what utilities may be below the surface. In many instances during construction of buildings, conduits & other utilities will be placed in the actual pour of the concrete floor or just beneath the concrete floor. The process will go much smoother if the areas are scanned with ground penetrating radar & radio detection prior to beginning the demolition process.

An electrical contractor took a chance with saw cutting an entrance area of the building without having it scanned first for any potential conduits. During the saw cutting they had cut through some electrical conduits that powered parts of the building. Before they continued to saw cut the areas they decided it would be best to investigate the floors for any more surprises. There were many unknowns as to what types & how many utilities were embedded in the concrete floor during the original construction. The building facilities didn’t have any records or drawings of what could possibly...

Never go in to a demolition project without having as much information as possible. It can be difficult to determine where new floor plugs & plumbing should be placed in the design phase without having any information as to where existing conduits/structures are below.

It’s essential to have as much information as possible before digging or drilling as to what utilities could be passing through underground. It’s even more essential when working inside an industrial facility with multiple electrical feeds passing through. The thought of digging, trenching or drilling prior to having a private utility locate completed, should never happen. The risk of injuries is too high.

A general contractor had a project where they needed to drill borings & trench throughout an industrial complex. It was unknown of the paths of any existing utilities passing through the area especially the electrical feeds. The general contractor had to connect the future electrical conduits to the existing electrical feeds. Prior to proceeding it was essential they had information to which direction the existing electrical was running so they could tie into it & also so they didn’t compromise it during the excavation process. The general contractor also needed to know if any other existing utilities were present before proceeding with the trenching...

Ground Penetrating Radar Systems was recently contracted to complete a site investigation prior to major renovation and construction at a local Miami mall. The mall was going to be staying open through all phases of the project and delays due to utility damages or other line-strike issues were a major cause of concern for both the Mall Owners and the General Contractors on site.

GPRS was tasked with not only locating and painting all the utilities including post-tension cables, conduits, rebar, and voids found on site, but also documenting the location of each utility with as much accuracy as possible. The technologies used on this project included the standard locating equipment (400 MHz antenna and EM locator), but also included a Geode (GPS collection device) and a Drone to create an orthomosaic map of the areas scanned.

Ground Penetrating Radar Systems of New Mexico recently visited a church parking lot to identify any underground utilities in the area prior to excavation for a new building. Klinger Constructors wanted to ensure that there would be no delays in construction due to severed utilities. The project manager on site was able to scan the proposed building area and identify any dangers in below the surface and map those dangers on the surface of the asphalt with precise depths.

Our project manager detected a deep circular disturbance about 20” wide that was connected to a pipe that would lead to a steel plate embedded into the slab. We found this pattern several times in the service garage. The owner of the garage was on site and made and recalled that the original garage used a piston system to elevate vehicles in the service garage. With the technology of GPR we were able to determine the location of the old pistons, and the lines that connected them to the hydraulic lifts. In this instance we were able to confirm that the pistons had been removed and there were no longer any UST or pistons below the surface.

In the picture to the side you can see our markings where there...

When an electrical contractor needed to do core drilling in a post-tensioned slab they called Ground Penetrating Radar Systems. GPRS was able to accurately locate all the conduits, rebar, and post-tensioning and provide them with area where they could safely drill. Ground Penetrating Radar is a very safe and quick method to locate reinforcement in large areas where cutting or coring is necessary.

Other services we offer are: underground storage tank locating, utility location, rebar locating, void location, and more. If GPR services are needed in Arkansas call Dave Schaff at (501) 251-4036 or e-mail at dave.schaff@gprsinc.com.

The pictures you see below are from a local attraction in Orlando, FL. The demolition contractor was removing a curb when they unknowingly broke a main feed line for the sprinkler system. This would normally not have been something difficult to remedy. However, they did not know where the shut-off valve was for the system. With this problem hundreds of gallons of water were wasted and the ground will have to be repaired prior to work continuing.

This is not an uncommon issue on job sites today. To cut cost contractors are performing site work, demolition and excavation without having a proper utility locate performed. Most argue that it is a private property and therefore the local “one-call” services will not perform the scan. This, however, is where Ground Penetrating Radar Systems really shines. We work in all conditions providing one of the most comprehensive and accurate utility locates available.

We can ensure you that your project will be safe and more cost effective before you start digging or excavating....
