Subsurface Utility Engineering (SUE)

Last updated: January 11, 2019

What Does Subsurface Utility Engineering (SUE) Mean?

Subsurface utility engineering (SUE) deals with the mapping of underground utilities such as pipelines and cable lines. Subsurface utility engineering also encompasses retrieving information on the present condition of existing subsurface utilities and when and how to relocate subsurface utilities. Subsurface utility engineering uses geophysics, civil engineering and surveying to complete its tasks.

Subsurface utility engineering can reduce unnecessary utility relocations and the likelihood that existing utilities will be damaged by new construction projects.


Corrosionpedia Explains Subsurface Utility Engineering (SUE)

If the location of a subsurface utility is accurately mapped then new projects can adjust their routes to avoid the existing subsurface infrastructure.

Subsurface utility engineering employs a variety of tools. Three-dimensional underground imaging radar is often used to determine the location of existing subsurface utilities when accurate maps are unavailable or if a high degree of certainty is required. Subsurface utility engineering also uses several methods of excavation to physically locate utilities. Vacuum excavation is a type of earth removal that is commonly used to find an underground utility.
