Step 1: Draw up your plans
Step 2: Lay out the footings
For this deck, there were a total eight footings (five on the minor deck and three on the major deck). They were 12" in diameter and 42" deep. There were cinder blocks in the way of the footings, and it was awkward and time consuming to remove the cinder block with a sledgehammer. A larger hole had to be dug to allow the sledgehammer to swing.
