Specifications include, but are not limited to: 1. Except as may be amended by this section, poles delivered under this contract shall generally comply with RUS Bulletin 1724E-206, Guide Specification for Spun, Prestressed Concrete Poles and Concrete Pole Structures. 2. All poles shall be designed by the ultimate strength method. Poles shall be spun pre-stressed concrete. The final shape of the pole shall be round; multi-faceted designs are not acceptable. 3. All poles shall be capable of withstanding the loading conditions as required per the Purchaser's loading tree or equivalency standard, with allowances for deflection, handling, transportation and erection. 4. All poles shall be designed to have a three-fourth (¾) inch minimum concrete covering over the longitudinal reinforcing steel and a five-eight (5/8) inch minimum covering over the spiral reinforcing steel.\ 5. The following design calculations and data shall be submitted with this bid for each pole type (i.e. height, and class, etc.) and shall include the following information: a. The controlling loads and loading case. b. General dimensions of the pole. c. Number, size, grade strength and location of all pre-stressing strands. d. Size, grade, strength and location of all spiral reinforcing strands. e. Twenty-eight (28) day compressive strength of concrete used. f. Ultimate moment, cracking moment, maximum stress of all reinforcing bars and pre-tressing strands, and the neutral axis in each ten (10) foot section of the pole at the attached points and at the ground line. g. Maximum and normal deflection for the controlling and each load case. h. Guy tensions with overload factors. i. Maximum stresses of all bracing and crossarms. 6. Once a Purchase Order has been issued, the successful bidder must supply, for approval, detailed fabrication drawings, as well as, all pertinent information included in this section of this specification, to the City of Alexandria Electric Distribution Department for approval. 7. Fabrication of poles shall not begin until the successful bidder has been notified that the City of Alexandria Electric Distribution Department has approved all materials.
