Call a Private Utility Locator Before You Dig

Underground private utility locating is critical to any construction project where subsurface excavation is planned. The excavation team and property owner are responsible for locating and avoiding any underground utility lines, public or private, beneath the construction site. Failure to accurately map and avoid these utility lines can result in expensive damage, costly delays and potential injury to your excavation team.

Not Your Average Underground Utility Locating Contractor

GPRS provides full service utility locating, both public and private lines, to help keep your team safe and your project on budget. One call state locators, like 811 services, are only responsible for locating the public utility lines. Their service, while valuable, fails to take into account the significant number of private utility lines, and can still leave you exposed to damages and delays.

GPRS offers you a comprehensive range of utility locating and reporting options, from marks on the ground, to basic field sketches, to a full-blown AutoCAD report pinpointing buried electrical, water, gas, communication, sewer and storm drain lines. Our state of the art technology and expert Project Managers will provide you with a permanent utilities location record for future reference.

Applications and Technology

Our equipment is second to none. We utilize the latest GPS technology to pinpoint subsurface utilities, map their locations and develop detailed AutoCAD reports for our customers.

Utility Locating and Injury Prevention

Safety and injury prevention are the top priorities at GPRS, as it is for our many clients. It’s at the core of all of our services, and something we take great pride in. From live electrical lines to gas and sewer utilities, your team can be exposed to danger if a utility line is damaged or compromised. An ounce of prevention, such as accurately mapping and locating the utility lines buried beneath your job site, can save you time, money and keep your construction safe.

Our utility detection services can locate electric, gas, oil, steam, communications, water, sewer, and storm lines. By locating these utilities, we help utility contractors and other construction workers avoid accidental strikes, one of the most common sources of construction related injuries.

Injury prevention is critical not only for employee safety but to keep projects running on time and on budget. Our project managers are rigidly schooled in all aspects of project safety prior to being certified for field duty. They also are required to take monthly refresher courses to stay current on all safety developments.

6 Frequently Asked Questions About Ground Penetrating Radar Utility Locating Services

1. Can GPRS find plastic pipes?

Yes. The technology and expertise applied to your project site allows for the discovery of the varying pipe compositions existing in the industry.

2. Can GPRS determine the type of utility it has located?

Our equipment can’t determine the type of utility we’ve found but, often, our project managers can. With their experience and knowledge, they can trace the line to where it surfaces and determine its type.

3. How accurate is your utility locating?

We’re very accurate. Specifically, + or – 6 inches to the center of the utility we find with depth accuracy at +/- 10-15%.

4. Can we get a permanent record of your findings?

Yes. We can provide you with a field subsurface utilities markings map and a detailed AutoCAD report.

5. How large of an area can be scanned for utility locations in one-day?

The size of the area that can be accurately located in one-day will vary based on the project site itself. Vacant/green fields many acres in size which are scheduled for residential development can be accomplished with great speed as the expected congestion of utilities is low. On the other hand, a small property (less than one-acre in size located on a busy metropolitan street) could be very time consuming as the anticipated utility congestion is high.

6. I have heard that saturated soils or a high-water table can be detrimental to the results produced using ground penetrating radar, is this true?

It can be. While the equipment used by GPRS is effective, it can be inhibited by moisture. It is best to contact your local expert GPRS project manager for more information on the soils native to your project.
