The slab-on-grade construction control joint detail specifies a saw cut extending one-fifth of the slab depth up to a maximum of two inches. Reinforcement is continued across the construction control joint since the slab functions as a structural diaphragm. The drawing explicitly prohibits through cutting or trenching across this assembly. A note requires the contractor to submit a slab-on-grade construction control joint plan for engineer review prior to pouring.
