About this detail

An eight-inch concrete masonry unit screen wall rests on a continuous concrete footing with a minimum depth of twelve inches and a width of four feet. The masonry wall has a maximum height of six feet and features solid grouted medium-weight blocks with a specified compressive strength of two thousand psi laid in a running bond. Vertical reinforcing consists of number five bars spaced at twenty-four inches on center with forty-six-inch lap splices, tied to number five vertical dowels extending from the footing with alternate hooks. Horizontal reinforcing consists of number five bars spaced at forty-eight inches on center with thirty-two-inch lap splices. The footing contains four continuous number five longitudinal bars and number five transverse bars spaced at twelve inches on center with three inches of clear cover. A slab on grade by others intersects the assembly above a thickened edge at the contractor's option, incorporating a water stop per architectural requirements and four continuous number five bars. A cap per architectural specifications finishes the top of the wall. General notes require one vertical bar at the ends of walls, one horizontal bar at the top of the wall, and prohibit openings without engineer approval.
