Practice Description: The project owner provides the excavator with
accurate location information on the proposed excavation area and scope of
work This information includes: a street address, street intersection, legal
description, a starting point, ending point and on which side of the property
(North, South, East, West, front, back, rear, sides, etc.) distance from nearest
intersection or other acceptable format and latitude/longitude if feasible.

Current Practice:
• Project owner provides information to excavator which is referenced to
the notification service map.
• Today, “starting and ending points” tend to be descriptions - not
coordinates; however greater use of mapping technologies will facilitate
this information being provided.
• There is currently a variety of referencing methods for tying-in proposed
construction (C/L, P/L, etc.) which is facility owner specific and may/may
not be tied to universal survey control points.
