About this file
This is a technical drawing specification document prepared by the City of Milwaukee Department of Public Works, Transportation Section, Street Lighting Division for a 31-foot bolt down aluminum pole. The drawing, designated B-14-14 and dated November 14, 2014, specifies the design and manufacturing requirements for street lighting pole infrastructure. The pole features a cast aluminum base plate sized for 1-inch mounting bolts with a 10" to 12" bolt circle diameter, a 31-foot total height from the bottom of the base plate to the top of the pole, and a 30-foot mounting height to the centerline of the bracket arm. The design includes specific dimensional requirements such as an 8-inch diameter outer diameter base, a 4-inch top cap of cast aluminum, two mounting plates positioned 180 degrees apart, and a hand hole measuring 4" x 6" nominal with a bolt opposite. The pole incorporates three equally spaced 1/4"-20 NC stainless steel hex head bolts and includes provisions for cable exit with specified hole drilling and deburring requirements.
The specification details material requirements including cast aluminum components conforming to ASTM #356-T6 and ASTM #319 standards, 7/16-inch aluminum sheet stock for certain components, and 1/8-inch radius detailing on select edges. The drawing references specification number 12c-C-1 and related drawing B-13-14 for a 14-foot pole variant. This technical drawing serves as the manufacturing standard for the City of Milwaukee's vendor contract for 25' and 30' black bolt down aluminum poles, which is part of a three-year contract period beginning from the award date in accordance with City of Milwaukee Specification No. 12c-C-1 dated October 30, 2025.
