GPRS Works on Major Pipeline – Davenport, Iowa

In a sea of hardhats, GPRS is found at the caboose of this construction train. Although GPRS was in the back of this line, our work was surely not. GPR and EM locating is crucial and always a first step in any big project.

GPRS was contacted by a major pipeline company to conduct four- way utility sweeps around their pipeline near Davenport, IA. GPRS was able to locate all critical lines prior to the contractors’ work on this pipeline. All scanning conducted was implemented through our SIM process.

GPRS was also able to provide the client with surface markings with depths of the structural steel as well as on site photos and a job summary report documenting any important information in regard to the scanning.

Our state of the art GSSI GPR equipment sends radio signals into concrete that send the data back instantly to locate objects. The radio waves are safe for workplaces so there is no need for any stop in work for floors below or around the scan areas. 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 using our transmitter box which sends out a frequency via induction or conduction with an exposed or known surface utility line.

“GPRS deploys the best equipment operated by skilled project managers who know how to solve your subsurface locating issue. Since our inception, GPRS has completed hundreds of thousands of projects in North America. Our accuracy rate on these projects? Over 99%” (

GPRS technicians are commonly called for a wide array of locating jobs, such as concrete scanning for rebar, mesh, conduits, radiant tube heating, post tension cables, and any other utility that may be buried. We also scan for private and public utility locates, underground voids or vaults, footings, buried foundations, and Underground Storage Tanks (UST’s). All of these tasks are done in a safe, time efficient, non-destructive manner.

Scan before you plan! This ensures worker safety and saves valuable time by targeting specific areas of concern. GPRS can provide GPS reports overlaid on Google Earth or overlay information on pre-existing CAD files for future building plans.

“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” (

At GPRS, safety is our #1 priority. When saw cutting, digging, or drilling, the last thing you or our technicians want is to run into any problems. While you may think that there is nothing buried in the concrete or ground, better think again…. There are an unfortunate number of people that call because they were proven wrong. The price of one of our technicians is well worth it compared to the costs of repairing a mishap later on.
