Start by measuring out the design and marking that onto the ground with marking paint. Using your marked out design, then prep the area, digging down 3 feet for the footings. Put the sonatube in the ground and pour concrete into the sonatubes. Let them dry overnight and set the deck support posts on top of them.
Build the frame, and then hang your joists with the crowns up, nail them into the frame, and then install joist hangers for extra strength. As you work, keep checking to make sure everything is level. Joists are usually sold with a slight curve along one of the thinner edges. This "crown" gives the joist extra strength for the decking and weight to come.
Once the supporting frame is in place, begin adding the deck boards. For this demonstration, 5-1/4" x 6" pressure-treated decking boards were set flush against each other. The boards will shrink, leaving a small space for water drainage.
