About this file
This is a technical drawing specification document prepared by the City of Milwaukee Department of Public Works, Transportation Section, Infrastructure Services Division, Street Lighting Division, for a 31-foot bolt-down aluminum pole design (Drawing B-14-14, dated 11-14-14). The drawing is referenced in conjunction with a commodity contract for 25-foot bolt-down aluminum black poles and transformer bases, governed by City of Milwaukee Specification Nos. 12e-F-31 (dated 12/28/2025) and 12c-C-1 (dated 10/30/2025). The specification establishes detailed technical requirements for the aluminum pole structure, including material standards, dimensions, mounting configurations, and component fabrication details necessary for street lighting installations.
The 31-foot pole design specifies a cast aluminum base plate (ASTM #356-T6 or ASTM #319) measuring 27 inches with an 8-inch outside diameter shaft, featuring a 4-inch mounting height to accommodate 1-inch anchor bolts configured in 10-inch to 12-inch bolt circles. The pole includes two mounting plates positioned 180 degrees apart, a hand hole (4-inch by 6-inch nominal) with cover and bolt, cable exit holes (one diameter hole drilled and deburred, one 2-inch hole drilled through), three equally spaced 1/4"-20NC stainless steel hex head bolts with a cast aluminum top cap, and a cover plate manufactured from 7/16-inch aluminum sheet stock. All cast aluminum components meet ASTM standards, with specific dimensional tolerances and finishing requirements detailed throughout the drawing to ensure compliance with City of Milwaukee street lighting standards.
