Phase III Steel Distribution Poles
City of Safford
As consulting engineers for the City of Safford, AZ, Transmission & Distribution Services has
been requested to provide specifications for eleven steel distribution poles. Poles will be mostly
engineered self-supporting (both direct embed and anchor based). Self-supporting poles shall
withstand all forces without guying, including full dead-end loads. One wood-pole equivalent is
needed. All poles shall have a self-weathering steel finish.
Enclosed is the design information and specifications for the poles. Included for each pole are
dimensions, load tables, loading trees and drilling guides.
Cross-arms are not needed in this quote. Owner will provide and attach wood cross-arms as
needed.
Load cases for the poles for each conductor are provided in the bid specifications. Poles are to
be manufactured to the guidelines specified in RUS Bulletin 1724E-204 “Guide Specification for
Steel Single Pole and H-Frame Structures”. All poles will require two stainless steel 2-hole
NEMA ground pads as indicated on the drilling guides. Direct embedded poles will have
Corrocote or equivalent protective coating from the butt of the pole, to the top of the
groundsleeve.
The quotation shall include the moments, axial loading, and shear for each pole as well as
dimensions, weights, and lead time/delivery schedule. Pricing, including delivery and all
applicable taxes, shall be provided for all poles. The FOB delivery site will be City of Safford
Warehouse, 373 W. Discovery Park Blvd, Safford, AZ, 85546.
