About this detail

A concrete pile cap supports a steel column connected via a base plate and anchor bolts embedded in the concrete. The pile cap features top and bottom reinforcing steel mats sized per the pile cap schedule, with a three-inch non-shrink grout pad beneath the base plate. Number four dowels are placed at eighteen inches on center around the column on all four sides, extending into the ground floor slab. At frame pile caps, the bottom mat steel includes one hundred eighty-degree hooks with a standard three-inch concrete clearance. The ground floor slab may be blocked out for column erection after the slab pour at the contractor's option.
