Infrasense Conducts Advanced Subsurface Utility Survey
Infrasense was recently engaged to perform a subsurface utility engineering (SUE) survey in a mountainous region known for its ski slopes. The project involved the collection of data using both electromagnetic induction (EMI) methods and state-of-the-art 3D ground penetrating radar (3DGPR). This innovative survey aimed to accurately map and analyze the positions, conditions, and potential obstructions posed by various utilities beneath the surface.
Details of the Survey Methodology
The field team managed to effectively employ both the EMI and the GPR methodologies to ensure comprehensive utility mapping. The EMI method is particularly effective for locating underground utilities, and during the survey, features such as transformers, utility poles, and catch basins were identified on-site. The team recorded each utility's location with precise RTK GPS technology, ensuring a detailed and accurate mapping operation.
Complementary Technologies Elevate Survey Accuracy
The combination of these technologies allowed Infrasense to achieve remarkable depth penetration of up to 12 feet during their survey. The versatile nature of the terrain encompassing both landscaped and open areas posed an interesting challenge, but the thorough preparation by the Infrasense team ensured successful data acquisition in a single day.
Applications of Utility Mapping
Mapping out the utilities involved not only identifying their location but also determining their depth and service types. By utilizing the 3DGPR system, the team could visualize underground features and measure the depth of each utility reliably. This capability allows clients to undertake safer construction activities, ensuring they avoid potential hazards associated with unidentified subsurface structures.
Advantages of Combining EMI and GPR Technologies
Through the integration of both the EMI and GPR approaches, the team brought together the strengths of each technique. The EMI method can pinpoint utility paths effectively, while GPR provides a more comprehensive view of subsurface conditions. By mapping the culverts through both mediums, the team ensured that data was not only accurate but also thoroughly vetted against pre-existing documentation.

Frequently Asked Questions
What is a subsurface utility engineering survey?
A subsurface utility engineering survey is a process used to locate and identify underground utilities and structures to prevent damage during construction or excavation.
How does electromagnetic induction work in utility surveys?
Electromagnetic induction works by applying a signal to underground utilities that can then be detected by a receiver, allowing for the tracing of utility paths.
What are the benefits of using ground penetrating radar?
Ground penetrating radar (GPR) provides detailed images of subsurface conditions, helping detect buried structures, utilities, and their depths more effectively than traditional methods.
Who can benefit from subsurface utility surveys?
Architects, engineers, construction firms, and environmental consultants can all benefit from the accurate data provided by subsurface utility surveys, enabling safer project planning and execution.
