MIL-HDBK-1025/10
b. If it is necessary to use mechanical equipment within 0.6 meters (2 feet) of a mark you
should expose the line first.
c. If you are paralleling a line, expose every 30 meters (100 feet) to verify the location
and depth of the line. If the utility location is not accurate, contact the facility owner immediately.
d. If using a boring machine, bore away from all facilities. If it is necessary to cross a
facility, expose the line to verify location and depth. This may require changing the bore route or
depth to avoid a facility. Contact your supervisor to approve route changes.
e. Never place excavated dirt or street plates on top of utility location marks. Keep
marks visible and fresh at all times.
Backfilling in Areas of Utility Locations
8.4.6
Note
Prior to backfilling, contact facility owners to inspect exposed facilities.
a. All lines exposed during excavation should be supported to prevent stretching, kinking,
or other damage.
b. "Shade" all lines, meaning clean, good fill dirt placed around the lines to prevent
possible damage.
c. All backfill dirt should be "clean fill" free of large rocks, sharp objects, and large
chunks of hard packed dirt or clay.
d. No cable or personal trash and no abandoned lines, or pieces of lines, may be backfilled
into the trench.
8.4.7 If Damage Does Occur to Existing Utilities. Complete a Construction Facility
Damage Report as provided by your activity construction office and submit to your supervisor.
a. If the damage involves a potential risk to life, health or significant property damage, the
excavator should call 911 or the local emergency response number.
b. All damages, including kinking or sheath damage, however slight, should be reported
immediately to a supervisor and to the facility owner or operator.
