Subsurface Utility Engineering:

Subsurface Utility Engineering:

“A branch of engineering practice that involves managing certain risks associated with utility mapping at appropriate quality levels, utility coordination, utility relocation design and coordination, utility condition assessment, communication of utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.”

[“Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data,” CI/ASCE 38-02]

So-Deep offers complete subsurface utility engineering services. The most common components are defined as follows:

QUALITY LEVEL "A"- LOCATING: Precise horizontal and vertical location of utilities obtained by the actual exposure and subsequent measurement of subsurface utilities, at a specific point. Minimally intrusive excavation equipment is typically used to minimize the potential for utility damage. Precise horizontal and vertical positions, as well as other utility attributes are shown on the final work product. Accuracy is typically set at 0.05' vertical, and to applicable horizontal survey standards.

QUALITY LEVEL "B"- DESIGNATING: This information is obtained through the application of appropriate surface geophysical methods to identify the existence and approximate horizontal position of subsurface utilities. “Quality Level B” data are reproducible by surface geophysics at any point of their depiction. This information is surveyed to applicable tolerances and reduced onto plan documents.

QUALITY LEVEL "C"- SURFACE VISIBLE FEATURE SURVEY: Information obtained by surveying and plotting visible aboveground utility features and by using professional judgment in correlating this information to Quality Level D information.

QUALITY LEVEL "D"- EXISTING RECORDS: Information derived solely from existing records or verbal recollections.
