Paint booth. Office. Lift. Lucky!!
Where are you putting your compressor?
in the model they are hard to see, but there are 2 compressors stacked in a corner behind the paint booth. I picked up a 5 HP 60 gallon low rpm compressor from a MN company called "C-Aire" about a year ago. It replaced an aluminum pump 2 stage high rpm unit on an 80 gallon tank that I had been running for about 15 years, which was a sams club special. My new C-Aire runs at about half the RPM and still makes more air than my old screamer. I will be purchasing one more of the same model compressor very soon and I will tie the 2 together and offset the cut in switches so that they come on in stages in need be. Mush of the time only one of the compressors will run, but if I'm using a lot of air the second unit will kick on and my CFM will double.

What kind of heat are you installing?
Have you considered boiler system for hot water in the floor.
Yes, pex tubing is going to be stapled to 2" Styrofoam insulation which will separate my heated slab from the earth below and around it. The rebar will go over the top of the pex tubing. The slab will have a thicker edge perimeter and I will also have thicker footing areas around the leg locations for the rotary 10,000 lb asymmetric lift. The slab will be heated with hot water pumped through the pex tubing. It is likely I will go with an electric boiler and have it powered by an "off peak" circuit.
For those that may be unfamiliar, "off peak" means the electric company basically has permission to cut power to that device during peak power load periods. This is going to happen on the coldest of days, they kill the power to that device to help free up capacity for other customers. I have been heating homes with this type of system in northern MN for about 14 years. The slab stores so much heat that most times you don't even notice that the power is being controlled. The kilowatt rate is substantially lower for these off peak circuits.

Your shop isn't big enough until you can stand in one end and look toward the other end and see the curve of the earth. Just as well have them take it to a 100' x 200' while they're at it.
I like the way you think, lol!
