Overloaded Pole Replacement Program

Houston, Texas

DCCM provided electrical distribution pole analysis for the Client’s pole replacement program. We received periodic spreadsheets from the Client listing numerous poles to be analyzed. The poles were deemed to be possibly overloaded structurally due to conductor size, type of framing, angle of distribution line, equipment, or other circumstances. Overloaded poles were evaluated to ensure proper clearances over roadways, railroads, or other types of terrain. Each pole had a unique six- or seven-digit identification number, and DCCM was able to locate the pole in the Client’s GIS mapping system. A notification, work order, and DDS project were created for each pole. We were limited to one pole per order, thus creating the need for multiple projects. The poles were spotted in DDS with adjacent facilities for analysis. Structural and profile analyses were performed for the overloaded poles. The structural analysis evaluated the side bearing, vertical bearing, insulator, guy, anchor, cross-arm, and stress on the pole itself. The profile analysis measured the clearance of the conductors under maximum load conditions. The structures were replaced with a larger/taller poles to meet the Client’s standards. A subsequent sketch, material list, and work order were created and scheduled for construction.
