– Damage Reporting: The immediate reporting to appropriate authorities
and the owner of any damage made or discovered in the course of
excavation or demolition work.
– Daylighting: The exposure of underground utility infrastructure by
minimally intrusive excavation practices to ascertain precise horizontal
and vertical position or other attributes. (Note: may also be referred to as
“potholing” or “test pitting".)

– Demarcation Point: The demarcation point (DM) is the point at
which the Facility Owner’s ownership of a distribution system, including
connection assets, ends. Privately owned infrastructure may continue from
this point that is not owned by or known to the Facility owner.
– Demolition Work: The intentional, partial or complete destruction by
any means of a structure served by, or adjacent, to an underground line or
facility.

– Depth: The vertical distance below grade.
– Designer: Any architect, engineer or other person who prepares or issues
a drawing or blueprint for a construction project or other activity that
requires excavation or demolition work.

– Electronic Mapping Data: Geospatial data that is in a format that can be
stored, edited, retrieved, viewed and shared electronically.
– Emergency: A sudden or unforeseen occurrence involving a clear and
imminent danger to life, health, or property; the interruption of essential
utility services; or the blockage of transportation facilities that requires
immediate action.

– Excavate or Excavation: An operation using equipment or explosives to
move earth, rock or other material below existing grade. (Note: Excavation
can include augering, blasting, boring, coring, digging, ditching, dredging,
drilling, driving-in, grading, plowing-in, pulling-in, ripping, scraping,
trenching and vacuuming).

– Event: The occurrence of an underground infrastructure damage, near
miss or downtime.

– Excavator: Any person proposing to or engaging in excavation or
demolition work for himself or for another person.

– Facility: See Utility Infrastructure.
– Geospatial Data: Data that identifies the geographic location (latitude/
longitude) and characteristics of natural or constructed features and
boundaries on the earth. Also includes facility location information and
notification areas.

– Geographic Information System (GIS): An organized collection of
software and data that is geographically referenced and used to capture,
store, update, maintain, analyze, and display geographically referenced
information.
