When it comes to the cost of utility locating, the most important thing to know is this: with GPRS, you only pay for what you need, and investing in accurate utility locating services saves you far more than it costs.

You can always count on GPRS for straightforward, upfront utility locating pricing built around your project goals and timeline, so you never pay for services you don’t need.

GPRS tailors every utility locating quote by project scope because every building and site are different. Utility locating pricing depends on several factors, including:

  • Soil conditions
  • Site size
  • Utility depth
  • Number of utilities present
  • Night/weekend work
  • Level of detail required
  • Deliverables required

Comprehensive Subsurface Utility Detection

You will receive on site field markings with spray paint and pin flags, color-coded to American Public Works Association standards, plus utility maps to give your team a clear understanding of the exact location, depth, and layout of all underground utilities on your job site, including:

  • Electric power lines, cables, conduit and lighting cables
  • Gas, oil, steam, petroleum, and gaseous materials
  • Communication, alarm or signal lines, cables or conduit
  • Potable water
  • Reclaimed water, irrigation, and slurry lines
  • Sewers and drain lines
  • Underground storage tanks
  • Abandoned lines
  • Unknown utilities
  • Manholes & well heads

Why Accurate Utility Locating is Essential for Damage Prevention

Utility locating services are significantly less expensive than the cost of striking a utility line.

A white paper published in April 2023 by the Infrastructure Protection Coalition (IPC) highlights major failures in the nation’s damage prevention system used to protect the public and prevent damage to underground utility lines. These failures are responsible for over $30 billion in annual societal and utility line damage costs, and an additional $61 billion in annual waste and excess costs.

The Common Ground Alliance 2024 DIRT Report, the only comprehensive accounting of buried infrastructure damages in North America, found that 9 of the top 10 known root causes of utility damages occur during utility work itself. This means that the very activities intended to install or maintain utilities are often the ones most likely to damage existing buried lines when locating is inaccurate.

Why Professional Utility Locating Matters

Accurate utility locating helps your team to:

  • Avoid costly strikes and delays
  • Keep your crew and site safe
  • Stay compliant
  • Prevent change orders and rework
  • Keep your project moving confidently and on schedule

Frequently Asked Questions

1) How does utility locating work?

Utility locating works by combining an existing as-built records review, federally mandated 811 ticket coordination for registered public utilities, and field detection to identify and map buried electric, gas, water, telecom, and other infrastructure before excavation begins.

For power plants, substations, and transmission/distribution sites, GPRS supplements One Call coverage by using ground penetrating radar (GPR) to detect both metallic and non-metallic targets and electromagnetic (EM) locating to trace conductive private/unregistered and public/registered lines with 99.8% accuracy. Then they mark-out and map their findings to reduce strike risk.

GPRS Project Managers adhere to the highest industry standard – Subsurface Investigation Methodology – which means that our processes and markings are standardized, and the deliverables can include field markings plus CADD and digital utility maps in PDF, KMZ, and SHP formats delivered through SiteMap®.

2) What is RTK positioning and how much more accurate is it than GPS?

RTK positioning stands for Real Time Kinematic Positioning and is a real-time GNSS correction method that uses data from a base station or correction network to improve satellite positioning from meter-level to potentially centimeter-level accuracy.

In typical field conditions, standard GPS/GNSS is often accurate within 2-8 ft., while RTK, in perfect conditions, can achieve roughly 1-2 cm. of accuracy, making it up to 244 times more accurate than standard GPS, depending on equipment, line-of-sight, and correction quality.

GPRS has integrated RTK positioning into our utility locating workflows as a standard operating protocol to geo-reference field data more precisely for mapping and reporting. Digital access to all deliverables is provided via our SiteMap GIS platform.

3) How does GPRS maintain 99.8% accuracy in utility locating and concrete scanning?

GPRS maintains 99.8% accuracy on utility locating and concrete scanning by outfitting and training Project Managers in multiple complementary technologies and a standardized subsurface investigation process (SIM) instead of relying on a single tool.

In practice, SIM-certified field team members compare their findings from GPR and EM locating, apply repeatable field methodology and processes, and use RTK-enabled geo-referencing, a process that has allowed GPRS to maintain a 99.8%+ accuracy rate across more than one million jobs.

The protocol is Subsurface Investigation Methodology (SIM). For concrete scanning, we further back up our deliverables with GPRS’ Green Box Guarantee.

4) What other services does GPRS provide for the power industry?

Beyond utility locating, GPRS supports the power industry with concrete scanning, 3D laser scanning and reality capture, NASSCO-certified CCTV pipe inspection, pinpoint leak detection, and updated as-built documentation.

GPRS’ nationwide Field Team of Project Managers helps power utility owners/operators and transmission/distribution teams document substations and plant infrastructure, inspect buried water, sewer, or process piping, detect leaks, and produce accurate models and drawings that reduce clashes, rework, and outage-related risk.

We can custom-design deliverables to mee your needs: 2D CADD drawings, 3D BIM models, meshes, point clouds, and more, WinCan CCTV reports (including video and PACP-coded defect classifications), PDF/KMZ/SHP utility maps, delivered via SiteMap for cloud-based infrastructure visualization and secure 24/7 data access.
