Specifications include, but are not limited to: It is the intent to describe in these specifications minimum functional and design requirements for galvanized steel street lighting poles for the City of Madison, Wisconsin. In these specifications, a clockwise or counterclockwise direction is as viewed when looking down from the top of the pole. All poles shall be designed to withstand a 90-mile-per-hour sustained wind velocity and a 117-mile-per-hour gust velocity, with any bracket arm(s) and typical roadway luminaire(s) in place. A. Handhole A 4" x 6-1/2" galvanized handhole shall be provided with a flat cover plate joined to the reinforced handhole frame with two screws. The handhole shall be located 90 degrees clockwise from the bracket arm of single arm poles, that is, at right angles to the curbside edge of the anchor base. For twin-arm poles, the handhole shall be 90 clockwise and 90 degrees counterclockwise from each bracket arm, respectively. The center of the handhole shall be approximately 14" from the bottom of the pole. B. Shaft The pole shaft shall be fabricated from the herein-specified manufacturer's standard gauge, best grade, hot rolled basic open hearth, or basic oxygen process steel. The shaft shall have only one (1) longitudinal, electrically welded joint, with the strength rated at not less than 100 percent of the yield strength of the steel and shall have no intermediate horizontal joints or welds. Only one (1) length of steel sheet shall be used, and it shall be formed into a continuously tapered shaft, having a taper of approximately 0.14 inches per foot. The weld shall be smooth, allowing the specified taper to be constant. The pole shall be within 1/4 inch in 10 feet of being straight and centered on its longitudinal axis.
