I'm building a deck as the floor of a 30' yurt. Construction is 4" x 6" joists on 4" x 4" posts, on pre-cast concrete pier blocks, on tamped gravel footings. Posts are 20" - 30" long. Lumber is pressure treated.
As I build the framing, I have many variables to measure: the plumb of the posts, the rotation of the posts, the level of the joists, the height of the joists relative to each other. Adjusting each one affects all the others, so it is an iterative process. I want to know when it's good enough, so I can stop iterating. I'm asking here about the plumb
