About this detail

A steel light pole mounts to a concrete caisson foundation using a base plate secured by four three-quarter-inch threaded rods with square or round plate washers. The caisson is reinforced with six number six vertical bars equally spaced, number four closed ties at twelve inches on center, and three number four closed ties at one and a half inches on center at the top. A one-inch non-shrink grout layer sits beneath the base plate over a concrete top finished with a quarter-inch per foot slope and a three-quarter-inch chamfer all around. The foundation provides embedment depths up to thirty-one feet maximum and four feet minimum clearance, surrounded by finish grade or sitework as occurs.
