GPRS Project-Melbourne FL

Post tension cables, electrical conduits, rebar and other structural steel, water pipes and various other objects are often found in concrete slabs. Construction companies, plumbing contractors, electrical contractors and renovation specialists are always in need of either core drilling through a slab or trenching through a slab on grade. Whatever the case may be, Ground Penetrating Radar Systems has an expert level of understanding when it comes to the need to “x-ray” or radar before you go penetrating a concrete slab.

In Melbourne, FL there are constantly needs arising when it comes to this. A local plumbing contractor was tasked with relocating some existing plumbing lines. Having used GPRS a time or two before, they felt confident the professionals there would be able to give them the attention needed to get through the slab without cutting anything critical and that they could locate the plumbing lines to be moved.

GPRS showed up on site and used the 1600 MHz and 400 MHz antennas to scan the floor. The professional on site scanned the entire area in a grid pattern to assure that there was no mistaking the location of the plumbing. Contractors only like to cut through a slab once if they can help it.  After mapping out the areas, the GPRS professional used markers to indicate where the plumbing was located. These findings were then relayed to the site contact to ensure all information was accurately communicated. The client was able to penetrate, cut and trench in the areas scanned without hitting or cutting any electrical conduits or critical structural steel. The client expressed gratitude on the quick turn-around time and skill the technician brought to the project. Clients who use GPRS know they are getting the highest level of service when using our product.

You will see a picture below depicting Nate Schmoe, of GPRS, Inc. scanning the slab on grade surface.

Prairie Cemetery project underway

Land owner Jim Moore, of Jonesboro, assures Brenda Hutcheson that there will be plenty of land for potential fencing when project is completed, along with Josh Sneed, Brandin Mathis, Wayne Couch and Ethan King.

The ancient Prairie Cemetery, south of Lake City, is being examined from above and below to find graves of loved ones buried there.

Riverside teacher and Lake City councilwoman Brenda Hutcheson spearheaded a project in January to reclaim the overgrown cemetery on County Road 812, one-and-a-half miles east of Lunsford.

“The cemetery has been overgrown with vines and brush for years,” Hutcheson said. “My husband Donnie (Hutcheson) and I were raised in the Prairie Community, and wanted to do something about cleaning it up. We only found two stone headstones at first, but remember there being over 20. Many markers had been wood and they were gone.

“We contacted Craighead County Judge Ed Hill about getting help from the county road crew to remove the thicket covering the cemetery. The road crew brought heavy equipment and removed 30 dump trucks of brush and debris.”

Hearing the story on KAIT-TV, Mike McGuirt, a teacher at Westside, brought his drone to the Prairie Cemetery to take photos before the county workers began and afterwards when the property had been cleared.

Volunteers came to the cemetery on Saturdays during February and March to rake and clean the surface of the cemetery. They probed for unmarked graves and located a third stone marker and a metal grave stake. ASU Archeologist Dr. Julia Morrow and her assistant Brandy Dacus examined the cemetery and advised Hutcheson as how to document the findings.

“Calls came in from everywhere giving me information about loved ones buried there,” Hutcheson said. “This has helped us uncover a lot of information about the people who lived in this area, as well as nearby schools, and organizations. Our desire is to give those buried here a proper resting place.”

Surveyor Michael Daniels, with the Bureau of Land Management, visited the site to look for what was first believed to be a section marker. The marker turned out to be the base of another tombstone.

Wilma Johnson Freeman, of Jonesboro, contacted Hutcheson to report five members of her Watkins family were buried there from 1892 through 1913.

“Wilma and her husband Ron Freeman came to the cemetery in hopes of finding the unmarked graves of their family,” Hutcheson said. “The Watkins family was willing to sponsor the cost to hire GPR scanning of the cemetery to find graves. Mrs. Freeman contacted Ethan King, project manager with Ground Penetrating Radar Systems, out of Little Rock, and he did the work last Saturday.”

King found 14 more grave sites on the cemetery property, much to the pleasure of the Freeman and Watkins family.

Ethan King completed GPR scanning at the cemetery Saturday.

“We believe we have found our Watkins family members on the south end of the Prairie Cemetery,” Mrs. Freeman said. “My cousin Sandra Whitmire and her friend Dwight Baker have already placed the cemetery on the Find-A-Grave site, listing the three headstone names, with hopes of soon adding our Watkins family to the listing.”

“Donnie’s cousin Harold Hutcheson, owner of Hutco Inc. of Paragould, also lived in this community growing up and has offered to construct an arched metal sign with the cemetery’s name on it after work is completed,” Brenda Hutcheson said. “He and his wife Viva came over here to work and have been great supporters of the project.

“Landowner Jim Moore has pledged his support in making sure we have enough space to clear the property and erect a fence when work is completed,” she said. “It didn’t take us long to see how interested people are in the work being done here. Even students from Riverside School and ASU came out to work. Local farmer Lynn Nall helped level the site for mowing at a later date.

“Now we are just waiting for the printout with the GPR results so we can purchase small concrete markers to identify the found grave sites. When we are finished we want to list the names of all those buried here on a marker near the metal arch out front. We are trying to raise money to pay for those and have already received several donations.”

Ma•ni•a•cal (məˈnīəkəl): exhibiting or denoting obsessive enthusiasm

Ma·ni·a·cal

As a Project Manager with Ground Penetrating Radar Systems, every once in a while, you’ll find yourself scanning through an endless field, under a cloudless sky, before a backdrop of the Oquirrh Mountains, all while focusing on a scrolling Radargram–basically a dream job.

You’re confident that there’s nothing in this field, and your site contact is confident that there’s nothing in this field, but your site contact’s customer has the policy to scan the ground before ANY penetrating of the ground (even if they’re just skimming off the top couple of feet to collect fill dirt). So you scan…and scan…and scan…and scan…then you STOP.

At times like this, the value of extensive training, attention to detail, and diligence becomes evident. Had the old drainage line (marked in red, per the customer’s request, for contrast purposes) that I found with my radar been found with an excavator’s scoop, that would have constituted a Stop Work Event, causing delays, expenses, and frustration.

Nothing that travels around in a GPRS truck has more money and attention invested in it than the Project Manager in the driver’s seat. Our customers depend on not only our impressive suite of tools, our network of experienced radar technicians that covers all of the US and Canada, or our exemplary response time. But also, unknowingly, they depend on the intense, unrelenting, and unapologetically maniacal emphasis we place on problem-solving, attention to detail, and safety.

To each his own, but if you found yourself nodding your head while reading this article, then your company probably suffers from (read: “prospers because of“) the same maniacal adherence to good values. If that’s the case, then we should consider doing some business together. You will be joining a long and growing list of customers who can’t get enough of our “obsessive enthusiasm” for getting their job done right and right away.

Give your local GPRS Guru a shout.

GPRS Scaling Skyscrapers

Chicago

Don’t be fooled by the lofty view, Chicago was nick-named the windy city for a reason!

As winds are raging, GPRS scans tight spaces atop a 48-story building in Chicago, IL. We were able to map out rebar so the general contractor could safely drill anchors for future building plans.  High or low, GPRS is here to help you on any subsurface locating you need to finish your project safely and timely. Don’t hesitate to call your nearest GPRS technician today!

Scan before you plan! This ensures worker safety and saves valuable time by targeting specific areas of concern. GPRS can also provide GPS reports overlaid on Google Earth or overlay information on pre-existing CAD files for future building plans. This is all done in a safe, time efficient, non-destructive manner.

20170126_122138One of our goals at GPRS is to keep all projects on-budget and on-schedule.

GPRS assists by giving a real-time depth view of subsurface hazards such as reinforcing, utilities, conduit, underground storage tanks, voids, etc. This reduces the likelihood of subsurface obstruction strikes during core drilling, saw cutting, trenching, soil boring, directional drilling, anchoring, and other sub-surface applications.

Ground Penetrating Radar Systems uses the GSSI (Geophysical Survey Systems, Inc.) Sir-4000 technology in locating. GPRS also uses the RD-8100 Locator to locate live power and radio frequency (RF) signals underground. We can also detect utilities in or under concrete via induction or conduction with an exposed or known surface utility line.

Time is a primary currency traded on any given construction project. At Ground Penetrating Radar Systems, our everyday efficiency in operations allows us to respond to the immediate needs of our customers, often within 24 hours or less. (gp-radar.com)

GPRS locates post tension cables in Washington D.C.

WashingtonDCA contractor investigating the structural components of a post tension building in Washington DC contacted Ground Penetrating Radar Systems of DC for concrete scanning. The contractor hoped to find valuable information about the reinforcing and post tension cables of the building before core drilling for anchors on the slab edge. GPRS was able to mark the depths of the reinforcing and cables accurately. GPRS scanning assists contractors by reducing the likelihood of subsurface obstruction strikes during drilling, cutting, trenching, anchoring and other sub-surface applications. Ground Penetrating Radar Systems, using GSSI Sir-3000 technology, located the critical post tension cables in the slab which allowed contractors to avoid a possible cable strike. GPRS has used different GSSI antennas to accommodate for ceiling work or even work in tight spaces giving clients data up to 1” close to walls or objects.  Information was given in real time, giving the contractor quick results with a safe place to drill in each location. This was all done in a safe, time efficient, non-destructive way.

If your company needs reinforcing or post tension mapping in the Northern Virginia, Washington D.C. Arlington, Alexandria or surrounding areas with fast response times and easy scheduling, please contact Stephen Yant at 703-851-3853 or at Stephen.Yant@GP-Radar.com.

GPRS Locates Electrical/Data Conduits at the Cleveland Clinic-Richard E Jacobs Health Center in Avon, Ohio

On December 19th 2016, Ground Penetrating Radar Systems (GPRS) was requested on site by a general contractor to perform a Ground Penetrating Radar (GPR) survey at the Cleveland Clinic-Richard E Jacobs Health Center.  The contractor needed to saw cut a trench to install new plumbing lines and remove existing drains.  The contractor needed to know if there were any conduits in the area to avoid saw cutting through them.  GPRS located two active electrical/data banks of conduits going directly through their saw cut area.  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 hospital had no drawings showing the banks of conduits.  Without GPRS on site, the contractor would have saw cut through them as they were right at the bottom of the concrete slab.  Before you saw cut or core drill, call GPRS to know what’s underground!

The pictures below show the banks of conduits marked out on site.
