A stepped concrete foundation wall bears on a continuous concrete footing. Vertical dowels and continuous Z-bars tie the footing and wall reinforcement together, matching the size and spacing specified in the structural schedules. A continuous 2x4 keyway forms the horizontal construction joint between the stepped footing and the foundation wall. Step dimensions and maximum height limits govern the geometry of the vertical offset.
