This Standard provides a framework for the classification of subsurface utility location and attributes information in terms of specified quality levels for the management of subsurface utilities.
This Standard applies to subsurface utilities and associated surface features that facilitate the location, identification and engineering management of subsurface utility infrastructure.
This Standard also applies to all existing (including redundant) and under-construction subsurface utility infrastructure.
For the purpose of this Standard, the term “subsurface” includes “submerged” (see 1.4.28).
This Standard does not apply to utility infrastructure that is above the surface, such as overhead power and telecommunication lines.
