Concrete slab-on-grade conditions incorporate both greater-than-slab-thickness and less-than-slab-thickness recess configurations. The drop configuration includes continuous number four top and bottom bars along with number four bars spaced at twelve inches on center, while dowels match the size and spacing of typical slab reinforcing with a forty-eight bar diameter lap. The recess depth is sized per plan up to eighteen inches maximum, transitioning smoothly into the adjoining floor slab.
