Subsurface Utility Engineering
If It’s Down There, We’ll Find It
Subsurface Utility Engineering, or SUE, is a process that allows engineers, designers, and project owners to “look underground” and map the utility infrastructure without massive excavations. This reduces conflicts and mitigates risks associated with digging and constructing blindly.
How We Do It
AMT’s SUE Team offers a wide range of services to support utility mapping requirements and has designated more than 5 million feet of utilities, performed safe excavation of more than 1,000 utility test holes, and has coordinated and designed utility relocation design for large highway projects. We understand our clients’ need for timely and economical services. AMT delivers quality, accurate service with support from our expert team of designers, engineers, planners and surveyors.
We employ the latest technology to increase the accuracy of our data including double ended connections, ground penetrating radar, and specialized tools such as the VacMaster 4000 system for test hole excavation. This equipment provides us with the performance required to excavate quickly, neatly, safely and both the air lance and the suction hose are some of the most powerful in the industry.
The American Society of Civil Engineers has implemented a standard of subsurface utility engineering manual titled CI/ASCE 38-02. Utilizing these criteria, AMT collects and depicts reliable data for existing utilities that is critical for making informed decisions and supporting risk management protocol regarding the impact of these utilities on your project.
Subsurface Utility Engineering Quality Level services provided by AMT:
Quality Level-A: called “locating” (also known as test holes), is the use of non-invasive vacuum excavation at critical points to determine the precise horizontal and vertical position of underground utilities, as well as the utility type, size, condition, and other various characteristics.
Quality Level-B: called “designating,” involves the use of surface geophysical prospecting techniques to determine the existence and horizontal position of underground utilities. The information obtained in this manner is surveyed to project control.
Quality Level-C: involves surveying visible utility facilities, such as manholes, valves, transformers, pedestals, etc. These structures are then correlated with existing utility records to depict the utility alignment.
Quality Level-D: information comes solely from existing utility records. This helps to provide for an overall “feel” of the underground utilities.
Additional Services: AMT also offers Geographic Information Systems (GIS) and other geophysical investigation options.
