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.

Surveying Solutions

Find the Solution for You

  • Boundary & Topographic Surveying

    We use the most up-to-date, efficient methods for collecting and staking data points for property and topographic surveys.

  • Asset Integrity & Waterway Inspection

    Our team stays on top of all of the current regulations regarding asset integrity and manageable waterway crossing requirements, allowing us to create fully customized solutions for our clients.

  • Hydrographic & Geophysical Surveying

    Our hydrographic surveying team inspects conditions on the seafloor and investigates any existing obstructions underwater, and is also capable of keeping an eye out for better search, rescue and recovery operations.

  • Unmanned Aerial Systems (UAS)

    This is a relatively new and rapidly evolving technology and surveying process, which involves the use of unmanned drones for safely and rapidly collecting large amounts of information.

  • Marine Positioning

    Our marine positioning services feature an extensive GIS and AutoCAD database of onshore, shelf and offshore wells, pipeline and platform data and hazard locations.

  • Laser Scanning

    Our 3D laser scanning services are the most advanced, efficient method of collecting survey measurements for a wide range of projects.

  • Dimensional Control Survey

    Dimensional control surveying allows our team to provide our clients with real-time, three-dimensional surveying results out in the field. It’s instant surveying information you would not get with many other types of surveying applications.

  • Subsurface Utility Engineering (SUE)

    We combine our SUE services with our various surveying and engineering solutions, which results in better risk management for underground utility mapping.

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. ”
