A concrete floor slab transition transitions in thickness with a six inch minimum dimension at a depressed slab condition. The construction joint features a continuous keyway, with edges tooled to a one-eighth inch radius and dowels matching the slab reinforcing extending across the joint. The control joint incorporates a similar step with slab reinforcing dowels and a sawcut performed within the first twelve hours of the concrete pour. Both conditions detail the slab thickness and reinforcement transition sized per the footing and foundation plan.
