SUBSURFACE

UTILITY ENGINEERING

If it is covered, we've got you covered

Subsurface Utility Engineering (SUE) is an engineering practice that combines engineering, surveying, and geophysics to provide reliable subsurface and above ground utility information.  SUE services can minimize unnecessary utility relocations and reduce unexpected conflicts with utilities which reduces project costs and construction time.  SJB Group has experienced engineers to deliver you the highest quality subsurface data to keep your project on time and within budget.

WHY IS IT IMPORTANT?

Subsurface Utility Engineering 

As the United States rapidly developed in the last century, under ground utilities paved the way for a cleaner and more enjoyable city landscape. However, records of the exact placement and locations of each utility has fell short of spectacular. This lack of records or the precision needed to construct safely is why so many private, municipal, and federal government agencies rely on Subsurface Utility Engineering. When SUE is performed on a project, you can expect significant cost savings from reduced construction delays, environmental setbacks, and preventable mistakes.

THE RIGHT GRADE 
FOR YOUR PROJECT 

Discover which level you need for your project 

No two projects are the same, therefore your current or future project may require different levels of SUE. Call us today to learn which quality level your project will require to give you the best data on your job site. 

QUALITY LEVEL 

A

Precise horizontal and vertical location of utilities is obtained by actual exposure and subsequent measurement of subsurface utilities, usually at a specific point. Utility location is documented to an accuracy typically 1.5 mm vertical and project specific parameters on the horizontal axis. 

B

Appropriate surface geophysical methods are applied to determine the existence and approximate horizontal position to subsurface utilities. Data should be reproducible by surface geophysics at any point of their depiction and surveyed to applicable tolerances. 

C

Visible above-ground utility features are surveyed and plotted. Engineers then use professional judgement to correlate this data to Quality Level D inofmation

D

Derived from existing records or oral relocations
