GPRS Locates Utilities in Fueling Terminal – Jacksonville, FL

Ground Penetrating Radar Systems was contracted recently to complete a utility locate within a fueling terminal prior to installing a new pipe rack. Even though the project was simple, creating a pipe rack for approximately 100 linear feet to support a storm drain pipe, the project could easily have been complicated if a utility was struck during the digging process. The foundations for the pipe rack were to be augured out and concrete poured in. It was necessary to locate the electrical conduit, water lines, control lines and other underground utilities prior to drilling for the foundations, as a disruption of these services could cause a major shut down for the terminal. Following the investigation the contractor was able to install all foundations safely, with minimal risk in regards to endangering his employees or the facility in which they worked.

If you would like similar work completed or have questions regarding the capabilities of GPR and our services, please visit the “contact us” page at www.gp-radar.com . In the image below you can see GPRS technician Adam Yunker scanning with the 400 MHz antenna to locate underground utilities near an existing pipe bridge.

Locating Underground Storage Tank at the Residential Home in Decatur, GA

Recently, GPRS was contacted to locate an underground storage tank (UST) and any other possible utilities within the backyard of a residential property. Plans for this property needed the location of the abandoned oil tank to be determined for any future work to proceed on the property.

With the 400 MHz antenna, GPRS technicians were able to scan a predetermined area and provide clear locations for soil borings. Using the 400 MHz antenna, the length, width and depth of the UST was able to be marked on the ground using spray paint. The 400 MHz antenna will typically reach depths from 8-12’. An SIR-3000 computer system is what displays the data for interpretation. Although this project did not require documentation showing the results of the survey, GPRS is capable of providing a written report to accompany the on-site markings.

In the pictures below you can see the UST clearly marked. With the mobility of the push cart we were able to scan the area in a quick and thorough fashion. The second photo is a probable septic tank that was not known to be on site and was added to be cored and sampled for the environmental studies.

If you would like a quote for a scan to possibly find a UST, please visit the “contact us” page at www.gp-radar.com to contact your local GPRS representative.

Utility Locate in Lehi, Utah

Ground Penetrating Radar Systems was contacted by America First Credit Union to locate utility lines before digging was to take place at the site for new foundations. GPRS technicians came out and successfully located electrical lines as well as utility lines. This was critical due to the neighborhood and other local businesses surrounding the site which could be devastated if a line was hit.

Lehi2

Ground Penetrating Radar Systems used a 400 MHz antenna for this application and a Radio Detection (RD) device to detect electrical current deep in the soil. All findings were marked with SUE marking paint directly on the surface for easy interpretation by the customer. GPRS’ 400 MHz antenna was ideal because of its accurate deep penetration and the open clear area the technician had to work. GPR was ideal for this application due to the active work site in the surrounding areas. GPR emits no radiation and is safe for others to work in the area near the scan location.
