Eliminate Strikes. Reduce Rework. Keep Power Projects on Schedule.

Electric‑power generation facilities operate under OSHA 29 CFR 1910.269, which governs work on generation and distribution systems. These environments present challenges, which include limited outage windows, tight tie‑in tolerances, and unknown embedded conditions in older structures.

Water‑based fire protection systems require inspection and leak detection per NFPA 25, while coring or anchoring without proper imaging risks striking rebar, post‑tension cables, or live utilities.

We support your power generation projects, whether nuclear, hydro, gas, coal, geothermal, or renewable. Our above and below-ground documentation services reduce risk and keep your projects running on time, on budget, and safe.

Transmission projects must follow strict clearance and safety rules. These rules are set by the National Electrical Safety Code (ANSI C2). This is whether you’re rebuilding overhead lines or installing underground corridors. To avoid redesigns, relocations, and costly utility conflicts, especially during HDD, teams rely on Subsurface Utility Engineering (SUE) practices defined in ASCE 38‑22.

GPRS provides utility locating and utility mapping services that support SUE.

Whether you're rebuilding overhead transmission lines in remote areas or installing underground power infrastructure in dense urban environments, GPRS delivers the precision and reliability you need.

Solutions

With our advanced utility locating services, GPRS Project Managers utilize ground penetrating radar (GPR) and electromagnetic (EM) technology to ensure accurate mapping of subsurface utilities on both public and private property.

Substations handle high fault currents. Mapping grounding grids and buried conductors is key. This helps reduce step and touch hazards, as outlined in IEEE Std 80. Work in these environments follows OSHA 29 CFR 1910.269 for qualified personnel and safety practices.

We help you locate and map grounding grids, duct banks, and private utilities. This way, you can plan safe excavation and lower the risk of step and touch potential during intrusive work.

For design and outage planning, teams often rely on millimeter‑accurate as‑builts and clearance data, typically delivered as E57 point clouds.

GPRS’ Reality Capture Project Managers use laser scanning on your switchyards, control buildings, and equipment clearances. This provides you with accurate as-builts and digital twins. You can use these for design, prefabrication, and outage planning. These highly accurate scans capture substations and plant applications safely away from energized equipment. Outputs support as‑builts, clash detection, and clearances for expansions.

Solutions

With our advanced utility locating and reality capture services, you receive clear field-verified utility markings, PDF and .KMZ maps, and, when needed, scaled CAD drawings or 3D BIM models. SiteMap stores all your data for easy, secure 24/7 access.

Distribution networks combine overhead spans with dense underground utilities. Overhead clearances and work practices follow the National Electrical Safety Code (NESC). For underground areas, risk is reduced by applying SUE quality levels from ASCE 38‑22 and by recording accurate as‑built data. For conduits, condition assessments and cross‑bore prevention often use CCTV inspections.

Whether your project is overhead or underground, we help you maintain safety and maximize efficiency.

Solutions

GPRS provides reality capture services for clearance verification and as‑builts on overhead lines, plus utility locating and NASSCO‑certified VPI for underground conduits. Our services also support horizontal directional drilling (HDD) planning with cross‑bore prevention and pre‑/post‑install inspections
