The Washington Monument Grounds are Scanned to Prepare for Upcoming Event

Recently, an event production company contacted GPRS to come out to Washington, D.C. and scan the lawn surrounding the Washington Monument for underground utilities. The scanning was done prior to the company setting up tents, trailers, and stages for the event. The production company had to drive a large number of stakes into the ground to act as an anchor for the equipment being set up. Josh Walker is a highly trained technician with the DC GPRS team; he scanned three areas around the monument which ultimately totaled two acres of land. He used the GSSI SIR 3000 with a 400 MHz antenna to scan the areas and followed up by performing sweeps with the RD 800 (radio detection device), which will pick up any live power or communication lines.

GPRS was able to exceed the expectations of the client by not only locating the utilities, but marking them out on the surface in real time using spray paint. The project was completed in a safe and non-destructive manner. GPRS of the Washington, D.C. area has the technology and the training to meet your needs in a timely manner, ultimately ensuring your projects get finished safely and on time.

National GC Contacts GPRS to Locate Utilities at a Major Airport

Ground Penetrating Radar Systems, Inc. – GPRS – of California was contacted by a major nationwide general contractor with whom we have business nationwide to locate utilities on the apron of a major airport. The purpose of this project was to locate utilities in an area where they were planning to install additional charging/fueling stations for the vehicles used on the airport’s apron. In addition to this, they needed to core and drill into the apron to install bollards to protect the stations. Joseph first swept the area with Radio Detection and attached the transmitter to all visible risers within 50’ of the area requested to be scanned. He then used GPR and confirmed depths on the locations that were found with the Radio Detection and attempted to locate additional utilities that do not transmit a power or radio frequency such as a drain/sewer line. Two conduits in the concrete slab and a sewer line at 3’ deep were located and the GC could proceed with their project with extreme confidence.

GPR is a great tool to scan areas of post tension cables, rebar, and conduits, including PVC pipes and can also be used to locate underground utilities prior to digging or excavating. GPRS has offices throughout the entire state of California and performs GPR scans throughout the entire state, including cities like Ventura, Santa Barbara, Thousand Oaks, Westlake, Malibu, San Fernando Valley, Los Angeles, Irvine, Glendale, San Diego, Riverside, Pasadena, Torrance, Orange, Anaheim, Long Beach, Lancaster, Palmdale, Bakersfield and San Luis Obispo.

Water Line Break Over a Weekend Requires the Rapid Response of GPRS

Water Line Break Over a Weekend Requires the Rapid Response of GPRS

Ground Penetrating Radar Systems Project Manager, Joseph R. Granados of El Paso Texas was contacted recently for an emergency at a local elementary school over the weekend. GPRS takes great pride in servicing locations within a 48-hour period, any day of the week. A water line had busted in the parking lot and the sub-contracting company wanted to make sure that the area was scanned before they excavated. Utilizing GPRS minimizes the risk of striking a utility. GPRS used ground penetrating radar to locate and map out the utilities before any excavation began. The area was scanned for utilities such as water lines, electrical lines, telecommunication, fiber lines, gas lines and sewer. All of the utilities were mapped on site, painted on the surface (with depth) to signify the location of the utility beneath the surface, and pin flagged. The sub-contracting company was able to clear the location without disrupting any live-utilities, or injuring any of their employees, thanks to the locate work completed by GPRS.

If you would like a quote or more information on how GPRS may be able to keep your job site safer and on schedule, please contact the El Paso, TX Project Manager Joseph R. Granados at 915-765-7442 or at joseph.granados@gp-radar.com. You can also visit our website at www.gp-radar.com.

Power, Data Lines and Other Utilities Located Prior to Excavation

Ground Penetrating Radar Systems (GPRS) was requested on site to perform a Ground Penetrating Radar (GPR) scan prior to an excavation project. The purpose of this survey was to identify any possible utilities in the designated areas prior to doing any excavating for trenching purposes. During this process we were able to mark out power and data lines in the areas where they had planned on digging. This helped the customer tremendously saving them valuable time and money down the road.

Curtis Hoag, RM of GPRS in Charlotte, NC used a GSSI (Geophysical Survey Systems, Inc) Ground Penetrating Radar Unit with one specific antenna. The antenna used on this project was a 400 MHz antenna along with radio detection. All findings were marked on the surface an communicated with the site contact.

Conduits and Reinforcing Steel Avoided for Installation of Speakers in Performance Arts Center

Ground Penetrating Radar Systems, West Palm Beach office recently scanned for rebar and conduits in a concrete slab where new speakers being installed in a local theatre; they needed to drill into the slab and the facilities department was concerned about damaging conduits while drilling.
Conduits and Reinforcing Steel Avoided for Installation of Speakers in Performance Arts Center

Ground penetrating radar was used to inspect 2 different areas on each side of the main stage. GPR uses electromagnetic signals to penetrate the concrete. The signals are sent to the SIR-3000 computer system for interpretation. The results are delivered in real time allowing work to continue with no delays. The inspection is performed quickly and accurately with no health risks. GPRS also offers private utility locating along with detection of underground storage tanks.

Reinforcing Steel Mapped on Elevated Slab with No Permanent Marks Prior to Core Drilling

Ground Penetrating Radar Systems was called to scan an elevated concrete slab in Kansas City, MO before core drilling was performed. The client didn’t want any permanent marks on the floor so the technician laid down painters tape wherever there was reinforcement. The technician was able to mark any reinforcement in the slab to allow the contractor to perform his work without striking any anomalies.

Industrial Facility Scanned for Utilities Prior to Digging a Trench

Industrial Facility Scanned for Utilities Prior to Digging a Trench

GPRS of Michigan was contacted by a general contractor to investigate a proposed trenching area to locate any underground utilities at an industrial facility in Detroit, MI. The general contractor had to connect the future electrical conduits to the existing electrical feed and it was unknown if any existing utilities were in the path of the proposed trenching area. It was essential for them to know which direction the existing electrical was running so they could tie into it without compromising it during the excavation process. They also needed to know if any other existing utilities were present before proceeding with the trenching to ensure the safety of everyone involved.

GPRS first investigated the surrounding area to locate any above-ground manholes to determine what possible utilities may be in the area. GPRS Regional Manager, Thad Bullock utilized a 400 Mhz antenna which has the capabilities of reaching depths of 8ft. depending on soil conditions. The RD-8000, which is a radio detection device, was also used to perform the investigation to ensure everything had been identified. GPRS was able to locate the existing electrical feed as well as some other unknown utilities passing through the proposed area of excavation. Thad was then able to interpret his findings with the onsite Supervisor who then had the confidence to begin the trenching project.
