LOL There will be signs! I, however, did not win the lottery.

That's 60 sheets of 1/2" flame treated.

I started framing this weekend. First time doing this so it took a little while to get it all figured out and get some speed. I put studs on 24" centers since this wall is not really holding anything. I didn't think to take any pictures of how I connected it. I used Simpson "L" brackets from the studs to the center purlin and flat ties from the top purlin to the top plate. Spacing is about every other stud with ties on each side of the I beams and on the I beams when possible. Pressure treated bottom plate and I got some 5/16 concrete anchors that I'll anchor the bottom plate with probably very sparce spacing.

Next is mounting my recep boxes. I put up a run of 3/4 conduit from the panel, running along the ceiling, then down into the framed portion. I'm planning on running 4 - 110 circuits through that and mounting receps in 4 square boxes about every 6 feet with alternating circuits in each set so if i need to power 2 high amp draw tools I can use receps next to each other and not have a problem. Once I get the recep boxes mounted I'll pull wire and get it all ready to terminate then mount my plywood. I'm planning on mounting my receps with the bottom of the boxes at 4' so I just have to make 3 cuts on the top piece of plywood and no cut on the bottom one. Also, I'm only planning 110 on this side of the shop. I'm planning on putting a 220 on the other side of the bay door and another couple close to the panel so I don't have to buy a ton of 10AWG wire.

My plan with the plywood is mounting it horizontal the top of the bottom sheet being the bottom "cut" for the recep boxes. The top sheet will just have a horse shoe cutout for the boxes. That's the easiest way I can think to do it. I can mount the bottom sheet all the way around and just lean the bottom sheet up against it while the edge is still on the floor, mark the spot for the recep, then cut the opnening on sawhorses or something.

Are you going to space the plywood off the concrete? Jon

Do I need to?

It's more important to have that space with sheetrock then plywood. The reason for doing so is to stop moisture from getting into it. With plywood in a shop, I don't see it as being an issue unless you have a lot of wet vehicles in there, and water actually getting to it.

For what it's worth my contractor friend as we were putting up OSB spaced it 1/2" up off the concrete. He said so it doesn't wick, OSB because drywall in a garage every time it gets bumped you have to patch.

Makes sense. Aside from a little more work I don't see an issue with leaving a little space. I'll factor that in. Probably just make a couple of blocks to use as spacers to rest it on while I nail the plywood.

Oh, I'm planning on just using some shorter nails in my framing nailer to install the plywood. Any reason not to do that?

Most sheathing is done with 8d nails, IIRC, so yes, just use shorter nails in your gun.

I'm thinking my contractor friend has OCD. He nails up plywood to hold then goes back with deck screws also.
