INSPECTION, MAINTENANCE, AND REPAIR - Prestressed Concrete Transmission Pole Structures - page 103

or framed structures tend to be structures subject to this type of condition.
Poles should be inspected for possible cracks in the area of curvature and
the Purchaser should be notifi ed to determine the proper course of action.
Guyed poles should be plumb and straight with all wires and attach-
ments installed and the guy wires installed to fi nal tensions. Guy wire
tensions should be checked during routine inspections and tension adjust-
ments made as required (see Chapter 8, Fig. 8-10).
After construction is complete, the alignment of crossarms, arms, and
attachments on a structure should be in accordance with design
specifi cations.
Other Items
The pole cap (if originally required) should be present. Absence of the cap
may be acceptable provided there is little or no evidence of corrosion. Usually
the Manufacturer can furnish replacement caps should they be needed.
The name plate should be present and visible. All attachments should
be secured and aligned properly; all bolts, nuts, and locking devices
should be present and properly fastened. The ground near the pole should
be checked for evidence of pieces or parts that may have fallen from the
structure, and it should be determined whether action is required based
on the fi ndings.
Some prestressed concrete poles have been treated with a color stain
or other coating. This application may have been for a barrier coating or
for aesthetics. The coating should be examined for any apparent deteriora-
tion. It may be necessary to consult the coating manufacturer should any
repairs be required.
Guy wires, which are important components of the overall stability of
a structure, should be examined and retensioned, if needed.
Per applicable codes, climbing devices, if present, should be inspected
and replaced as needed. To inhibit climbing by unauthorized persons, no
climbing devices should be permanently installed below the required
elevation above ground.
Grounding systems and attachments should be checked for proper
installation to prevent electrical damage to the pole and other related
components.
MAINTENANCE AND REPAIR
Minor repairs to the concrete pole or galvanized steel components can
be addressed by a fi eld crew. An example of minor damage to a concrete
pole is a small area of local surface spalling of concrete that does not
compromise the pole's structural integrity.
