TRAFFIC SIGNAL POLE INSPECTION
Raleigh and Durham, North Carolina
In the summer of 2003, Ko & Associates was selected by the Bridge Maintenance Unit of the North Carolina Department of Transportation for the first ever inspection program for metal traffic signal poles and mast arms. We were charged with identifying, documenting, and inspecting all of the metal poles on state-owned roads in Wake, Durham, Franklin, and Person Counties.
The initial contract was for an estimated 250 poles in division 05, but by the end of the contract period our teams had identified and inspected nearly twice that number. Due to the rapid growth in urban areas of the state and the fast track installation of signal poles and mast arms, it was vital for NCDOT to have an inventory of the location and condition of the poles that are in place.
