Subsurface Utility Engineering
An Engineering Process
Subsurface Utility Engineering (SUE) is a multi-phase process combining civil engineering, surveying tactics and geophysics. SUE involves managing certain risks associated with utility mapping at appropriate quality levels as defined in CI/ASCE 38-02 - The Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data. SUE is an important component of any design to prevent change orders, utility damage and project delays.
Informing the Design Professional
We investigate utility records to develop an extensive inventory of all utility systems. We then proceed to the site with electro-magnetic detection instruments to trace the course of each utility from a surface feature. Additionally, our crew conducts a sweep of the project site in an effort to discover undocumented or unknown utilities. If conditions are suitable, Ground Penetrating Radar is used to investigate non-conductive utilities.
We process the survey, including field markings and features, to produce preliminary utility mapping. A/I/DATA utilizes professional judgment based on years of field and office experience to determine the most appropriate quality levels for utility mapping. We then provide you with a map that gives you the information needed to better manage the potential risks associated with existing underground utilities.
You don’t have to survey your project alone. A/I/DATA provides custom investigation of the underground. We work with you to investigate and map all existing utility systems in the project area.
