Im building a 30 x 40 shop that is essentially going to be built on a deck frame type structure due to the shop is partially located atop an incline. I priced it out and between building it that way versus putting up a retaining wall and concrete, the deck frame is a third the price. So, my question is, what kind of thickness of flooring will I need for my shop? Im thinking 3/4 pressure treated plywood on top of the frame, which would be pressure treated 2x8 joists, 16 on center with 2x8 spacers between the joists as needed. I have the typical machine equipment: 6 jointer, 14 bandsaw w/ riser kit, contractor table saw, floor drill press, 13 planer, etc. The point is, I dont have anything insanely heavy that myself and a buddy cant lift. Is 3/4 plywood enough for a floor? Do I need more? Any thoughts on this from people with experience in building a wooden floored shop would be much appreciated. Thank you.
