LIGHTING POLE FOUNDATION DETAIL 1.pdf

This is a technical specification document for a lighting pole foundation detail related to a state and local contract opportunity in Colorado, specifically the OAAA 2010 Buckley Space Force Base Building 1000 MOV Repair project. The document provides construction specifications for a reinforced concrete foundation designed to support a lighting pole installation. The foundation utilizes Class A concrete with a 3,500 PSI minimum compressive strength, measuring 24 inches in outer diameter and extending 6 feet 6 inches in depth below finished grade. The design includes eight #6 reinforcing bars positioned vertically and equally spaced around a circle, with #4 tie reinforcement at 12-inch on-center intervals and a minimum 12-inch lap, along with (2) #4 ties within the top 5 inches of concrete. The foundation accommodates four ASTM F1554 3/4-inch diameter brass 36 hex head anchor bolts positioned on a bolt circle with 2.5 inches minimum clear spacing.

Critical construction requirements include a 1-inch chamfer on finished edges, an insulating grounding bushing on all exposed galvanized steel bend ends at the pole base, and a minimum 54-inch above-finished-grade (AFG) height in parking lot areas and regions subject to military vehicular damage. The contractor is responsible for verifying all anchor bolt dimensions, size, and bolt circle specifications with the lighting standard installer prior to foundation installation. The document specifies a conduit adaptor coupling connection detail and includes provisions for undisturbed ground bearing capacity verification during installation.
