Whether it's a renovation project or new build construction, the likelihood of needing to cut or core concrete is high. There is an inherent risk of striking rebar, conduits, and post tension cables during the cutting or coring process. If a striking occurs, repair costs begin to add up, delays creep into your schedule and it creates a safety hazard for your employees.

Private Utility Locating Contractor

Utility line strikes are on the rise, and yet many excavation contractors only follow local or state regulations to call “811” before digging. These services are only required to find public utilities, however, leaving the private utility lines to guesswork.

What You Need to Know: Private utility lines exist alongside public utilities, and are not being identified by standard utility locating services. If your project strikes or damages a utility line while digging, you will be responsible for repairing the damages.

Utilizing any private utility locating contractor still may not be enough unless a thorough investigation takes place prior to digging, there is still a lot of risk for a line strike. GPRS has a proven process and track record to not only locate subsurface utility lines, but to provide complete maps after the investigation to help ensure that your dig is safe.

GPRS can provide your team with a wide range of subsurface utility mapping options, from simple field sketches to a full-blown AutoCAD report, pinpointing exactly where buried private utility lines lie. Our advanced reporting will provide you with a permanent utilities location record for future reference. Scan once and make sure your job site is ready for your team to start digging.

GPRS utilizes the latest concrete scanning equipment to identify utility lines embedded in the concrete, providing fast and reliable layouts marked directly on to the concrete surface.

What You Need to Know: Scanning the concrete to locate subsurface private utility lines will minimize the risks of striking electrical conduits, sewer lines, rebar, post tension cables and more, saving you costly repairs and downtime in the process.
