Alignment of the utility with engineering stationing at each running
line change or PI (point of inflection) including signs and markers.
Bridges, culverts, and rivers.
All road crossings, overhead viaducts and underpasses, including
name of the street (public or private) and mile marker/marker post
designation.
Small scale maps that show the overall utility route.
Physical characteristics and attributes of the system, such as
pedestal, pole, transformer, meter numbers, anode bed, size,
material, product, and pressure.
The number of utility lines or conduits owned by the facility
owner/operator in a corridor, or the size of the duct package/bank.
Records processed by Subsurface Utility Engineering on the actual
locations prior to design of new installations.
CURRENT PRACTICE:
The one-call centre should be able to receive either a
digital or hard copy of the information. However, the onus remains on the
centre members to provide updates in a facility owner designated format. The
facility owner/operator uses this format to provide facility information to
locators. In addition, centre members who wish to exchange digital information
can use a standard “common file” for spatial information.

PROJECT OWNER RESPONSIBILITIES AND USE OF MAPPING
PRACTICE STATEMENT:
The project owner provides accurate information on
the scope of the work and determines the starting and ending points of the
excavation area. Providing the basic coordinates should define the centerline or
area of construction.
