Day 1: Saturday (High temperature 95 degrees)

On Saturday I installed the floor joists:

Day 2: Sunday (High temperature 96 degrees)

On Sunday I added plywood strips in the bottom of the joist bays, held in place with 1x2 strips to form a bed for the insulation. I then added the insulation, followed by 3/4" OSB T&G sheathing. I miscalculated slightly on the amount of insulation needed so I still have one piece of sheathing left to install. My generator ran out of gas toward the end also so I wasn't able to trim the sheathing where an 8' foot piece went in a 6' space (14' wide floor).

Here are pics of a makeshift workbench I built and the tarp I put over the structure.
