6.19 As-Built Mapping of Underground Electronic Utility Markers73
The location of underground electronic utility markers is identified on as-built mapping, GIS mapping, and/or other underground facility mapping documents.
Appropriate asset data collection and data management procedures are in place after completion of the underground facility installation. Primary among these is the practice to note in all as-built mapping where path and point markers are installed to increase the awareness of the existence of underground facility markers during the locate process.
