Concrete construction joints in a concrete-on-metal-deck slab are supported by wide-flange beams and girders. Continuous reinforcing steel extends over the joint, with double-two-inch continuous form boards positioned above and below the reinforcing at the joint interface. Conditions occur both perpendicular and parallel to the metal decking, featuring specific center-line offset dimensions of four feet typical for beams and five feet typical for girders. General notes require the contractor to submit a construction joint layout for architect and structural engineer review prior to construction and limit the pour length-to-width ratio to one and a half to one.
