UTILITY-LOCATING TECHNOLOGIES (R01B)
Two functional prototypes were developed: a multi-channel ground-penetrating radar system to locate utilities in one pass and a new multi-sensor platform that combines electromagnetic induction and 3D ground-penetrating radar to produce utility location data.
|
Locating underground utilities is made more complicated by variation in material types, soil types, and depth of location. Combining sensor technologies on a single platform can save time, improve accuracy, and provide data that designers can use to engineer site-specific project solutions.
|
The project is complete. Both technologies require further development to be commercially viable. The final report is forthcoming.

Staff Responsibility: Jerry DiMaggio
The purpose of this research was to bring together and develop creditable nondestructive geophysical techniques onto a land-based towed platform capable of detecting and locating underground utilities under all geologic conditions.
This project supported improvements in the detection and accurate determination of positions of buried utilities beyond Quality Level B as defined by CI/ASCE 38-02, the Standard Guidelines for the Collection and Depiction of Existing Subsurface Utility Data. The proposed combinations of new and/or existing sensor technologies and analysis software must offer significant advances in terms of utility detection and position (horizontal and vertical) from the ground surface across a wide range of soil types and site conditions. Enhanced utility detection is the primary objective. The technology was validated by field tests of a multi-sensor platform that supports near-real-time utility detection and location.
The SHRP2 R01B research project resulted in the development and improvement of advanced technologies (detection sensors, analysis software, and work procedures) that contribute to a multi-sensor approach that offers subsurface utility engineers and geophysical service providers the best chance at completely and accurately detecting, locating, and characterizing subsurface utilities at any location across the United States and the world.
Status: The project is complete.
