Subsurface Utility Services
From public utilities to municipal water districts, our clients are constantly striving to deliver their products and services to their customers as efficiently and safely as possible. Most of the time, this requires substantial work below ground. Subsurface Utility Engineering (SUE) and Subsurface Utility Mapping (SUM) are critical steps in executing these projects safely and effectively.
At Whiteley Infrastructure Group, our combination of advanced surveying techniques, our proprietary GIS database, and decades of identifying unknown subsurface features, allows us to provide our clients with all of the data they need to safely, efficiently, and reliably deliver on their project. Whether it is ground-penetrating radar, high-density laser scanning, hydro-excavation, or detailed land-use history research, our team at Whiteley Infrastructure Group is well-equipped to ensure that your project succeeds – no matter how large the challenge.
Standard of Care
The American Society of Civil Engineers (ASCE) has developed an important standard of care guideline, Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data, CI/ASCE 38-02.
This standard guideline describes four quality levels of utility depiction:
Quality Level A
Precise horizontal and vertical location of utilities obtained by the actual exposure and subsequent measurement of subsurface utilities, usually at a specific point.
Quality Level B
Information obtained through the application of appropriate surface geophysical methods to determine the existence and approximate horizontal position of subsurface utilities.
Quality Level C
Information obtained by surveying and plotting visible above-ground utility features and by using professional judgment in correlating this information to Quality Level D.
Quality Level D
Information derived from existing records or oral recollections.
Whiteley Infrastructure Group can demonstrate a thorough knowledge and understanding of the major SUE activities and we can provide these services to the extent desired by our clients.
