[Superseded]Classification of subsurface utility information, Part 2: Subsurface utility engineering
This Standard provides a framework for the management of information and decision-making tools for projects that may impact subsurface utilities. It has been written primarily from an engineering perspective, and applies to all existing (including redundant) and under-construction subsurface utility infrastructure and associated surface features. This Standard does not apply to utility infrastructure that is above the surface, such as overhead power and telecommunication lines.
