TAP Positioning

When dressed out and supported, the TAP should be 6 ft., (72 in.) off the pole, and the MFC
should be one foot (12 in.) off the pole to the CO side of the pole, unless designed for another
distance based on the engineering drawing. See Figure 6.

PAM Marker

An orange pole alignment marker (PAM) marks the center line measurement from one pole to
the next. It is placed by the factory according to the measurement specification provided by the
engineer. PAM markers are shown in Figure 7.

As the cable is placed from pole to pole, each PAM should be watched by the line force for
negative or cumulative drift in relation to the poles. As drifting grows in either direction, a
maximum tolerance of approximately 4 feet is an indication that corrective action be
considered. Examples of corrective action are introducing slack coils if the drift is in the
direction of placement (PAM is positioned after the pole; long), or taking advantage of
engineered slack coils if the drift is against the direction of placement (PAM is positioned
before the pole; short).
