Subsurface Utility Engineering

3D Subsurface Utility Engineering (3D SUE) is an engineering process that helps to locate and map underground utilities and pipelines. It provides a 3D mapping of utility systems necessary for facility design.

SUE services can include utility design, utility coordination, surveying and mapping, 3D analysis and imaging, ground penetrating radar, GPS surveys, and geographic information systems (GIS).

Federal Highway Administration (FHWA) encourages the use of SUE on Federal-aid and Federal Lands Highway projects as an integral part of the preliminary engineering process through MAP-21, a new surface transportation law.
SUE is used by transportation departments (DOTs), local highway agencies, utility companies, and highway design consultants.


Our experienced and highly trained staff includes engineers, surveyors, and GIS technicians that have successfully provided all four SUE quality level services to state, municipal, and private clients.
