Plano metal is legacy office cable and copper in brick ranches

Plano’s Legacy and the older telecom campuses still decommission rooms of cable, ladder rack, and raised-floor pedestals. That is a documented commercial pull, not a trunk of mystery wire. If you do not have permission from the building, do not send it.

The houses west of Central and in the 1980s sections are repipe and remodel work: copper, brass valves, and a water heater every time a kitchen opens. Those loads are clean and small. Do not bury them under the office steel if both jobs land on the same day.
