Ground Penetrating Radar used to locate conduit, rebar, and post tension cable in downtown Phoenix, Arizona. Ground Penetrating Radar Systems, LLC. – GPRS of Arizona was contacted by a major national general contractor to locate rebar and post tension cable within the concrete flooring of a new high rise project in downtown Phoenix, AZ.
In this sensitive project, it was essential that the location of all reinforcements such as post tension cable, rebar, and live power conduits be located, to confirm that they would not be damaged during any core drilling or concrete cutting processes.
With Ground Penetrating Radar Systems' trusted history of accurately locating structural steel within concrete on dozens of previous projects for this major contractor, GPRS was immediately called upon for this unexpected and urgent work. GPRS arrived on site within 24 hours to provide digital concrete imaging (ground penetrating radar) to provide illustrations marked directly on site in real time, to provide an accurate mapping of the rebar beneath the concrete wall's...more
Ground Penetrating Radar Systems, LLC. serving the entire state of Arizona as well as nationwide, was contacted by a major commercial contractor to conduct location services of all underground utilities for an upcoming excavation and soil boring project.
The excavation area was a commercial manufacturing plant that operated 24 hours a day. It was critical to locate all underground utilities, as any damage to the utilities during soil boring or excavation work could cause catastrophic and costly damage as well as severe interruption and loss of business to the manufacturing plant that these utilities served.
Ground Penetrating Radar System's services were ideal on this site as all utilities were located within a few short hours. Findings made it very clear that the area was very congested with many utilities, including water, electrical power / conduit, sewer lines, gas, and fiber optic lines. GPRS' services were essential for providing the necessary information to excavate and conduct soil borings with safety and avoiding costly utility...more
Ground Penetrating Radar Systems, LLC. of Phoenix, AZ. was contacted by a general contractor to locate PT cables in a high rise building for one spot for a 2” core drill. The customer was aware of the reinforcement in the slab in this particular area from photos prior to pouring concrete, however the customer needed to be sure of what was there by using GPRS. GPRS was quick to respond to this project to help the customer in a timely manner. GPRS was able to identify all obstructions in the slab so that the customer could feel reassured that there was indeed an area in which the 2” core could be drilled. All of this was accomplished by using a 1600 antenna. By having GPRS on site for the scanning, it allowed the customers schedule to stay on time with this project and kept them from hitting any reinforcement in the concrete slab.

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...more
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. Ground Penetrating Radar is an excellent tool to utilize when trying to layout floor cores. GPR can detect structural beams, conduits, reinforcing steel, etc. inside or below concrete structures.
A general contractor had a project inside a Medical Facility in downtown Phoenix, AZ where they needed to core drill holes from the 1st to the 4th floor. The core drills were needed to install new utility pipes that passed through all 4 floors of the building. They also had some areas in the basement of the building where saw cuts needed to be made prior to installing new plumbing & electrical. The building was still being used for classes & couldn’t have any existing utilities compromised during the drilling process. It was essential to have as much information as possible on what was...more

Ground Penetrating Radar Systems, LLC. of Phoenix, AZ. was contacted by a solar contractor in Tucson, AZ. to locate PT cables on an outdoor basketball court. The contractor was looking to install multiple support columns to carry the load of new solar panels over top of a basketball court at a park in Tucson. Four of the columns were to run between the two basketball courts through the concrete. It was very important to scan this area prior to cutting the concrete for the install of these columns to avoid cutting into any Post Tension cables. Once scanning the four locations we were able to show the client that where they wanted to install the columns, it was loaded with approximately six post tension cables running the entire length of the basketball court.

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...more
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.more
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. This allowed the project to proceed on schedule and without injuries due to damaged utilities.
Private utility locating with ground radar is an excellent way to precisely locate anything below the surface because it does not depend on the utility being active. Soil imaging is also used to locate underground storage tanks and coffins because of its ability to “see” many different obstructions in the soil. If you would like to know more about private utility locating in New Mexico, contact your local Project Manager today at...more
