6.19 As-Built Mapping of Underground Electronic Utility Markers73
Practice Statement:
The location of underground electronic utility markers is identified on as-built mapping, GIS mapping, and/or other underground facility mapping documents.
Practice Description:
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.
