Utility Locating & Mapping

Accurate Mapping for Smarter Planning

Overview

Infrasense utilizes a suite of nondestructive testing (NDT) methods including Ground Penetrating Radar (GPR), 3D-GPR, Electromagnetic Induction (EMI), and Electromagnetic Conductivity Meter technology to locate and map subsurface utilities and obstructions.

The NDT data can be geo-referenced using high-precision, differential GPS coordinates to accurately integrate targets or areas of concern into site survey drawings. This type of comprehensive utility locating prevents costly excavation damage, reduces project delays, and ensures worker safety by providing an accurate depiction of the subsurface.

Capabilities

Locating and marking out underground utilities
ASCE 38/22 Guideline for Investigating and Documenting Existing Utilities
Detecting other underground objects
i.e. storage tanks, manhole covers, concrete structures
Identifying the depth and service type of utilities
Compiling findings
and mapping utilities in CADD compatible format

Results You Can Trust

In addition to onsite mark-outs, the geophysical data can be processed to provide the following:

  • Subsurface Utility Engineering (SUE)
    Quality Level A through D services for comprehensive utility risk assessment and project planning coordination.
  • CADD compatible maps
    Which include both the type and positioning of each utility.
  • Geospatially referenced results
    Allowing integration into ArcGIS

Technology & Tools

Ground Penetrating Radar

GPR detects buried utilities by sending electromagnetic pulses underground and analyzing reflections from underground targets such as pipes, cables, and conduits.

Electromagnetic Induction (EMI)

Electromagnetic induction identifies targets passively or actively by reading a magnetic field of conductive service line. An active source can be added to targets with an exposed access point, for direct tracing and marking of its underground path.

Electromagnetic Conductivity

Electromagnetic conductivity tools measure subsurface electrical properties to detect buried objects, voids, contamination, and geological variations.

Total Station and GPS

Total Station and GPS provide precise positioning and measurement capabilities for surveying, mapping, and construction layout projects.

Other Subsurface Testing Technologies

Several other types of subsurface technologies that complement traditional locating methods for comprehensive underground mapping.

“For a complicated project in Harvard Square, Kleinfelder hired Infrasense to conduct GPR of the roadway, redline tunnel and the utilities using Infrasense’s technology. The data was proven to be valuable to determine the existence of utilities in question where records were not complete, the roadway structure, and the MBTA redline tunnel where we were not able to get a permit to excavate to locate the top of the tunnel due to permitting issues. The data and technology has come a long way and was proven to be invaluable.”
— Tyson Ross, Senior Project Professional, Kleinfelder
“We’ve partnered with Infrasense on a range of projects over the years, and they’ve consistently delivered. Their team brings deep technical expertise, professionalism, and a willingness to go the extra mile—especially on fast-moving or complex jobs where precision matters most. When we need GPR or specialized NDE, Adam is always our first call.”
— Mollie Rhett, Director of Marketing, ICC-IMS

Have a Question?

  • Our multi-technology approach using GPR, electromagnetic induction, and conductivity methods provides accurate utility locations with depth and service type identification that prevents the $50,000+ average cost of utility strikes. By delivering CADD-compatible mapping that integrates with project plans, contractors can excavate confidently while avoiding the project delays and safety risks associated with unexpected utility encounters.

  • Quality levels range from records research (Level D) to precise surveying of exposed utilities (Level A), with our NDT methods typically providing Level B designation through geophysical detection and mapping. Most projects benefit from Level B services that provide accurate horizontal positioning and approximate depth information without expensive excavation, offering the optimal balance of detail and cost-effectiveness.

  • Yes, our GPS-referenced results integrate seamlessly into CADD systems and GIS databases, allowing direct incorporation into construction plans and survey drawings. This capability enables real-time coordination between utility locations and proposed construction, reducing design conflicts and supporting accurate project planning while maintaining precise spatial relationships with existing site features.
