2026_04_10_ POLE BASE DETAIL_UPDATED.pdf

This is a technical specification document for light pole base construction design. The specification details the installation requirements for a light pole capable of withstanding 110 mph winds under Exposure Category C conditions. The pole must be finished to match the fixture and installed with a base plate secured by anchor bolts in 3000 PSI normal weight concrete. The design assumes a soil bearing pressure of 2000 PSF in the project area. Reinforcement consists of six #5 vertical rebars with standard 90-degree hooks at the bottom, #3 ties spaced 12 inches on center with the first tie positioned 3 inches from the top of the pier, and 3 inches of clear cover throughout. A 5/8-inch by 10-foot copper clad steel ground rod must be driven a minimum of 2 feet below grade, with #6 bare copper ground wire installed in 1/2-inch PVC conduit and bolted to the pole base cover plate at the handhole. The pole height measures 7 feet above grade with 2 feet below grade and 3 feet for the anchor bolt pattern area.

The specification includes critical notes requiring verification of anchor bolt pattern and locations with the manufacturer's template prior to base construction, and mandates grouting under the base plate only after the pole is confirmed plumb. An exothermic connection is specified for the grounding wire installation. This technical document serves as a construction guide for contractors and ensures compliance with wind load requirements and proper electrical grounding standards for the light pole installation project.
