GPRS Provides Peace of Mind for Crews on Wind Farm

GPRS was recently contacted by a large energy corporation to locate underground utilities at one of their new wind projects in Oklahoma.  The work consisted of using radio detection and ground penetrating radar to locate and mark out utilities that were along the collection lines, transmission lines, and turbine sites on the wind farm.  Andy Dermer – GPRS Oklahoma – performed the work by scanning the designated areas and marking the locations of utilities directly on the ground with marking paint, pin flags, and wooden stakes.  These findings were also recorded to be used in a Google Earth file for future reference.  With renewable energy on the rise, Ground Penetrating Radar can be an invaluable tool to help keep the site safe.  Due to the instantaneous results GPRS can provide, the information is immediately available to prevent accidents or injury on the job site.

“GPRS has done another outstanding job providing subsurface engineering work across Northern Oklahoma locating several pipelines that had been otherwise forgotten about over the years, and providing the crews a peace of mind that they can dig safely. The GPRS team has shown dedication to their craft, an impressive work ethic while operating in harsh conditions and most importantly displaying exceptional communications skills that are vital to building a successful windfarm.”

As-Built Plans Inaccurate? Call GPRS for Peace of Mind

Ground Penetrating Radar Systems of Virginia was utilized to detect underground utilities at a construction site in Glen Allen, VA. The as-built plans were inaccurate and the customer needed a particular fire-water line located. GPRS Project Manager Josiah Donaldson verified the location, depth, and direction of the 30 year old+ water line at approximately 5’ deep. As a result, the customer updated the as-built plans and successfully avoided expensive pot-holing and searching for the lost utility.

GPRS Technician Scans Floor from Crawl Space to Avoid Disrupting Office Staff

Ground Penetrating Radar Systems, Inc. – GPRS – of Southern California was contacted by an HVAC company in order to mark out the rebar in a ceiling prior to coring an 8” hole for a new AC unit. We found that the slab was 6” thick and the rebar was 12” on center.  We had to scan the area from the bottom as the floor above us was occupied with office desk/portables. The client wanted to preserve as much rebar as possible due to the building’s being considered a historical landmark so we marked out a 5’x5’ area and provided the customer with several coring options.

GPR mapping is a great tool to scan for post tension cables, rebar, and conduits; it can also be used to locate underground utilities prior to digging or excavating. GPRS has offices throughout the entire state of California and performs projects in cities like Ventura, Santa Barbara, Thousand Oaks, San Luis Obispo, Bakersfield, Lancaster and the greater Los Angeles area.
