Eliminate Strikes, Reduce Rework in Power Delivery

Utility locating identifies, verifies, and maps buried public and private utilities before trenching, boring, or duct bank work begins. For contractors, these services are used to confirm existing conditions, support safe excavation, and improve coordination across the jobsite. GPRS provides 99.8% accurate utility locating and mapping to help contractors reduce utility strikes, clashes, and delays on power delivery projects.

GPRS locates underground power lines by combining ground penetrating radar (GPR), electromagnetic (EM) locating, and Subsurface Investigation Methodology (SIM), along with other complimentary technologies. This process helps identify buried utilities, verify their paths, and estimate depths where possible. Findings are field-marked and uploaded into SiteMap using Real-Time Kinematic Positioning (RTK), so you can review your utility data before construction begins. RTK Positioning provides accuracy within inches, compared with standard GPS accuracy within eight feet.

A standard GPRS utility locate includes field mark-outs, PDF and KMZ utility maps, and SiteMap Personal access. These deliverables give contractors a clear record of utility paths for coordination and construction planning. You can also request 2D CADD drawings, 3D BIM models, and other digital as-builts for planning, design, and historical documentation. Learn more about our Utility Locating Services here.

3D laser scanning uses Light Detection and Ranging (LiDAR) to capture exact existing conditions of power facilities, structures, and sites. LiDAR is a remote sensing method that uses pulsed laser light to measure distances to a target. This scan data supports planning, design, coordination, clash detection, and record documentation across power delivery projects. GPRS converts laser scan data into point clouds, virtual tours, 2D CADD drawings, 3D BIM models, and 3D mesh models that help project teams work from accurate as-built information.

GPRS attains industry‑leading accuracy by deploying a multi‑technology methodology that integrates ground penetrating radar (GPR), electromagnetic (EM) locating, and other complementary technologies. All GPRS Project Managers are trained and certified in SIM. SIM is a step-by-step guide that uses experience-based training, multiple types of locating technologies, and applied methods and practices to achieve a very low investigation error rate. This structured workflow reduces uncertainty in congested transmission corridors, substations, and generation facilities. Learn more at Utility Locating Services and Concrete Scanning Services.

Concrete scanning helps power teams cut, core, and drill safely in generation facilities, substations, transmission sites, and distribution systems. GPRS uses GPR to locate rebar, conduit, post tension cables, voids, and other embedded hazards before crews install equipment, make penetrations, or begin upgrades. This helps contractors reduce damage, limit rework, and protect critical infrastructure in high-risk environments.
