Subsurface Utility Engineering

Subsurface Utility Engineering

Combining Surveying & Engineering Solutions

TBS combines subsurface utility engineering (SUE) with our surveying and engineering solutions to help manage the risks associated with underground utility mapping. Our SUE project team uses cutting edge geophysical prospecting tools and techniques to designate the horizontal position of subsurface utilities as non-destructive vacuum excavation is used to verify and record their exact vertical and horizontal location.

Integrated Project Approach

Using our integrated project services approach allows TBS to accurately and precisely record, interpret, and manage data derived from SUE in accordance with DOT standards. All data is processed and housed within the TBS GIS system.

Quality Levels

T. Baker Smith’s SUE Solutions are performed using four quality levels of utility depiction in compliance with the ASCE Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data.  (CI/ASCE 38-02)

  • Quality Level A: Underground Utility Locating (Test Hole)

    Highest level of accuracy available and involves the use of non-destructive digging equipment at specific points to determine the precise horizontal and vertical position of underground utilities, as well as the type, size, material, and other characteristics.

  • Quality Level B: Utility Designation

    Collected by thorough applications of appropriate surface geophysical sensing technology to determine the horizontal position of subsurface utilities. Example methods: RD 8000, GPR, Metrotech, Non-destructive probing, etc.

  • Quality Level C: Visible Surface Feature Utility Survey

    Utility surface feature data is obtained from surveying and plotting above ground utility features (e.g. manholes, valve boxes, etc.) to assist with determining approximate horizontal position of underground utilities. Used with QL-D.

  • Quality Level D: Records Research/Data Collection

    Information is derived from existing records research or verbal recollections (oral history), providing an overall “feel” for the congestion of utilities, but is often limited in terms of comprehensiveness and accuracy.

Customer Satisfaction

We let our customers speak for us

“ As a Landman, I have worked on projects with T Baker Smith for many years. I continue to utilize their services because they are professional, trustworthy and assist me, the client, in finding the most efficient resolution for varying types of challenges whether it’s surveying or permitting. ”

Carol M. Sledge, CPL
“ What keeps me coming back to T. Baker Smith is the dedication that Kenny and his team exhibits every day; it is one of the most valuable things to me. I cannot recall one time TBS did not follow through on getting what we asked for. You get what you pay for, and with TBS, we do not have to sit and babysit or redo the work. ”
Craig Guidry

“ We have worked previously with other consultants and find that TBS’ reliability and capability are superior to their competition. They are always available to assist us at Rebecca, Magnolia, Coulon, Acadia, St. Bridget and Evergreen Plantations as well as the Bayou Lafourche Freshwater Reintroduction project, by providing surveying and modeling support. ”
