Professional Utility Locating & Ground Penetrating Radar Surveys (GPRS)
UES provides Professional Utility Locating and Ground Penetrating Radar Surveys (GPRS) to help owners, architects, engineers, contractors, developers, municipalities, and agencies identify subsurface features that may impact design, excavation, or construction activities.
Our team helps locate underground utilities, storage tanks, tunnels, voids, buried structures, and other below-ground conditions that can create risk during project planning or construction. By combining advanced geophysical methods, geospatial tools, and professional interpretation, UES delivers reliable subsurface information that supports safer work, better design decisions, and more confident construction planning.
What is Professional Utility Locating & GPRS?
Professional Utility Locating and Ground Penetrating Radar Surveys (GPRS) are used to identify and document underground utilities and subsurface features before excavation, construction, renovation, or site development begins.
While traditional private utility locating often relies on limited methods and field markings alone, UES takes a broader investigative approach. Our licensed engineers, geologists, and geophysicists go beyond single-channel GPR by using an advanced geophysical toolkit that may include multi-channel ground penetrating radar (MCGPR), magnetometry, acoustic locators, electromagnetic methods, GPS/GIS data collection, and other complementary technologies.
By integrating multiple geophysical and geospatial methods, UES can often develop multiple lines of evidence to improve the accuracy, reliability, and usefulness of subsurface findings.
UES Professional Utility Locating and GPRS services may include:
- Ground Penetrating Radar Surveys to help identify utilities, tanks, voids, tunnels, and subsurface anomalies
- Professional utility locating for private, public, active, abandoned, known, or unknown utilities
- Use of advanced geophysical tools, including MCGPR, magnetometry, acoustic locators, and other complementary technologies when appropriate
- Identification of underground utilities such as water, sewer, stormwater, gas, electric, telecommunications, conduits, and other buried infrastructure
- Evaluation of storage tanks, tunnels, vaults, voids, buried structures, debris, and other subsurface features
- Review of available utility maps, as-built drawings, site records, and project documentation when provided
- Field markings, utility maps, reports, 2D drawings, 3D deliverables, CAD files, GIS-ready data, or digital documentation
- Support for site investigations, pre-design planning, excavation planning, construction coordination, and risk mitigation
- Practical interpretation of findings to help clients understand potential conflicts and next steps
Why it Matters
Unknown or poorly documented subsurface conditions can create significant risk during design, excavation, and construction. Utility strikes, unexpected obstructions, buried structures, and inaccurate records can lead to safety concerns, costly delays, change orders, design revisions, and damage to critical infrastructure.
Professional Utility Locating and GPRS helps clients:
- Identify potential subsurface conflicts before work begins
- Reduce the risk of utility strikes and related safety hazards
- Improve design accuracy and excavation planning
- Support safer construction sequencing and field operations
- Reduce uncertainty caused by incomplete or outdated utility records
- Improve coordination between owners, designers, contractors, and field crews
- Support permitting, pre-design planning, site investigations, and constructability reviews
- Make better-informed decisions using 2D, 3D, and digital utility locating deliverables
Field markings can provide value, but many projects require more than paint and utility flags. UES helps clients turn subsurface information into practical, usable data that supports safer and more efficient project execution.

Frequently Asked Questions
What can Professional Utility Locating and GPRS help identify?
Professional Utility Locating and GPRS can help identify underground utilities, storage tanks, tunnels, voids, buried structures, conduits, vaults, debris, and other subsurface features that may impact design, excavation, or construction activities.
How is UES different from traditional private utility locating?
UES goes beyond traditional single-method utility locating by using an advanced geophysical toolkit that may include GPR, MCGPR, magnetometry, acoustic locators, electromagnetic methods, and other complementary technologies. This allows our team to develop multiple lines of evidence and provide more useful 2D, 3D, and digital deliverables when needed.
When should utility locating and GPRS be performed?
Utility locating and GPRS should be considered before excavation, drilling, trenching, demolition, site development, design, renovation, or construction activities where unknown utilities or subsurface features may create risk.
Can UES provide more than field markings?
Yes. In addition to field markings, UES can provide utility maps, reports, 2D drawings, 3D deliverables, CAD files, GIS-ready data, and other digital documentation to support design, construction coordination, permitting, and risk management.
Does GPRS guarantee that all utilities or subsurface features will be found?
No subsurface investigation method can guarantee that every utility or feature will be identified. Results depend on site conditions, depth, soil type, utility materials, access, congestion, and available documentation. UES uses multiple geophysical and geospatial methods, professional interpretation, and field experience to improve confidence in findings and help clients make informed decisions.
