The big day is coming up next week.
I need to make sure I'm not misssing any great in-floor items before I pour the slab. Here's what I've got so far: Elec. service is in, water is in, floor drains nearly done, I'm buying some 1 1/2" pvc for a air line to the far end of the shop, I'm pouring in some pieces of tubing with a 3/4" nut welded in (flush to the floor) for chaining down frames and stuff, that's what I've got so far.
What am I missing ?

depending on what you want to do i dont think a 3/4 nut is gonna hold anything. but one of my buddys put a 4' solid steel bar in his shop for something to pull against. Also if you ever plan on running a lift find the spot now and make that part deeper. and maybe a reciever hitch in the ground to put a stand for bending grinding etc...

I installed two of the cup's (like they used to have in gas stations) in my slab. It has big cross bar's in a footing and chain's in the cup. Also has lid.s so you don't get hooked up in the holes. They should have drain's at the bottom unless you don't mind them full of water & rusting chains.

I've been debating the "nut" issue...I might tap some solid stock for a longer thread...I'd think 3/4 size should be enough.
I thought about the "cups" but I'm thinking a flush threaded hole might be more useful.

Oh I see what your doing now. Good idea if they hold.

I would caution about using PVC pipe for the air line in the slab (or anywhere else for that matter). If the slab would happen to crack (and they all do somewhere particularly if you put control joints in them and the pipe is in the actual concrete),then the PVC pipe will crack and leak air and be a bitch to fix.
If you do a google search on 'pvc air line' you will see within the 1st 2 pages of hits a few articles about warnings about using PVC pipe, especially above ground. If you do go with it I'd at least transition to pipe the last few feet and where it comes through the slab to steel pipe so it won't get broke off if hit. I'd also use big sweeping elbows so if it does ever break you could snake a prety good sized air hose through it. If the shop isn't heated the pvc is going to get more brittle in the winter.
If you are building it with a permit then all the local building codes apply (which means all the stuff in the slab needs to be inspected before the concrete is poured). You might want to consider rigid conduit (not the thinwall stuff), again with sweeping elbows if you ever want to snake something through it. I'd probably use '1 inch black pipe' if it was me though and then I'd think about getting a good air drier at the beginning of it to try to keep the moisture out, otherwise moisture is going to collect in the pipe and cause other problems. Oh, and if you do use steel then protect it with a sleeve where it comes through the concrete so the concrete doesn't start to corrode it.
