Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data

Development of the referenced Standard began in 1996. It is slated for publication in summer of 2002. The intent of this standard guideline is to present a system of classifying the quality of data associated with existing subsurface utilities. Such a classification will allow the project owner, engineer, constructor, and utility owner to develop strategies to reduce risk by improving the reliability of information on existing subsurface utilities in a defined manner. This document, as a reference or as part of a specification, will assist engineers, project and utility owners, and constructors in understanding utility data quality level classifications.
