SUE LEVEL D, C, B & A
Planview USL supports all quality levels of SUE
while managing the associated risks with utility
coordination, mapping, relocation, condition
assessment and design.
The Planview USL SUE team adheres to the 38-
02/38-22 ASCE and CSA S250 standards. Our
SUE team reduces utility conflicts, enhances
safety and mitigates unnecessary alignment
changes, translating to a reduction in utility
relocation costs and a savings in design and
Level D: This is the most basic level of SUE
and is typically used for project and route
planning and uses existing utility records/maps
and as-built drawings.
Level C: Locating and surveying visible above
ground utility end points and capturing invert
measurements on catch basins and manholes.
Level B: The application of surface geophysical
methods to determine the existence,
whereabouts and horizontal position of the
Level A: “Daylighting” The utility is exposed in
a “Test Pit” using non-destructive methods like
hydro-vacuuming. The utility is captured via
GPS coordinates to 1.5 cm level accuracy. The
highest level of accuracy available.
