About this detail

An eight-inch solid grouted concrete masonry unit screen wall is supported by a twelve-inch thick concrete footing with a minimum eighteen-inch embedment. The footing is reinforced with four continuous number five bottom bars and transverse number five bars spaced at twelve inches on center, maintaining a three-inch clear cover. Number five vertical dowels spaced at twenty-four inches on center with alternate hooks extend from the footing with a forty-six-inch lap splice into the wall. The wall incorporates number five vertical reinforcing bars at twenty-four inches on center with forty-six-inch lap splices, and number five horizontal bars at forty-eight inches on center with thirty-two-inch lap splices. A concrete slab on grade by others intersects the wall above a thickened edge at the contractor's option, with a water stop per architectural specifications. The wall reaches a maximum height of six feet and is capped per architectural details, with specific structural notes requiring single vertical bars at wall ends, single horizontal bars at the top of the wall, and prohibiting openings without engineer approval.
