About this detail

An exterior concrete grade beam measuring three feet wide by one foot six inches deep supports an adjacent concrete slab and exterior curtain wall or cladding assembly. The grade beam is reinforced with five number five bars top and bottom, extending two feet six inches minimum into the concrete pedestal, and number five ties spaced at twelve inches on center with three inches typical concrete clearance. A continuous keyway with waterstop is provided at the cold joint between the grade beam and slab, with insulation applied to the exterior face per architectural drawings. Slab dowels match the size, grade, and spacing of the slab reinforcement and tie the slab into the grade beam assembly.
