Subsurface Utility Engineering (SUE) quality levels explained

07.08.25 / Uncategorized

ASCE standard guidelines for SUE is broken into 4 different quality levels of accuracy for underground utility information. These range from Quality Level (QL) D (the lowest level) to Quality Level A (the highest level). The use of quality levels allows both facility owners and design engineers the flexibility to decide what level of accuracy they would like for any subsurface infrastructure to best design around. Accurate knowledge of what is underground helps reduce conflicts encountered during construction and thus saves the project owner both time and money in the end.
