About this detail

A typical concrete pile elevation interfaces with a variable-thickness pile cap. The 18-inch diameter pile features longitudinal reinforcement spaced equally around the perimeter with variable spiral pitch zones, including number four spirals at two-inch pitch for the top ten-feet six-inches and number four spirals at nine-inch pitch below. Spiral units require one and one-half extra turns with 135-degree seismic hooks at each end. A full-height center bar utilizes an A706 mechanical coupler or approved equal type-two splice as required. The top of the pile extends into the pile cap with outer eight bars featuring 90-degree hooks, while the center bar terminates with a headed bar or terminator per ICC ESR-2935. Notes specify waterproofing details, lowering the bottom of the pile cap where dimension A exceeds three inches, and increasing pile cap thickness by A-minus-three inches accordingly.
