It's not whether it's sandy or not, it's to hold down a 12' X 60' sidewall sail during a monsoon, or micro burst, wind. Plus the poles are cast into the concrete footing, not J-bolted or wedge anchored. The slab is poured at the same time so, it's all monolithic.
Around here, buildings have to be rated for winds up to 80 MPH. The 30X60 slab is stable enough to keep it from sinking or shifting.
I did all that stuff myself (well, I hired a backhoe) but used a 90A breaker so I could run 2 AWG in a 1-1/2" pipe for the main service. I still have 2 - 50A runs inside for the air compressor and the welder.

I need 30amp circuit for compressor and 50amp circuit for my big welder. I would also like a dedicated 20 amp for my 110v welder that I use for sheetmetal. Lighting, and can't forget a radio and the beer fridge. lol
I had to buy underground cable to wire up a mobile home decades ago and remember the cable being hella expensive. Probably have to have a bigger box or secondary box put in on the house to get this done. That part of the job is above me.
Yeah, I have a 20 hole panel in the shop. The lights are on their own circuit as well as each door opener. Then I ran 3/4" EMT conduit with 3 - 20A (12 Ga) to each side so, I have 6 different circuits in the building. I installed an outlet about every 10' down the wall with a different circuit in the neighboring outlet. As an example, circuit #1 to the 1st outlet, #3 to the next one, then #5 to the 3rd. Rinse and repeat until you get to the other end of the shop. Plus I have a double duplex box (4 square) near where my battery powered tools are kept. Odd circuits are on the South wall and even ones on the North. The 50A cuircuits are in their own pipe. All the wire is stranded THHN. I pulled a ground wire from the house main and tied it to the sub panel and then, to the frame of the shop. Since we have solar the house main has 3 - 8' ground stakes and, with the shop frame grounded, I have 8 - 32". ha ha. As in our trucks, you gotta have good grounds
Just to give anyone an idea to use and/or improve upon

Ironic. I just got off the phone with my buddy. Talking about the contractor he used to do his building. Sounds like you did yours with similar methods.Yeah, I have a 20 hole panel in the shop.

I'm looking at buying 180' of 2/2/1/0 MHF (mobile home feeder) to run to my shop. Last I checked the wire alone was going to run me around $1000.
Do you mean 2/0, 2/0, 1/0, 4 cable. That's for a 200 Amp service with the neutral being smaller and the ground 4 AWG. Are you gonna have a 200A sub panel in your shop?
Yup, sorry, 2/0, 2/0, 1/0, 4 cable. My shop has a 100 amp panel 150' from the 200 amp service to my wife's shop. Her shop also has a 100 amp panel.
So, why that big of wire? Just throw a 90 amp breaker in your main panel and run 2, 2, 2, 6 wire. That breaker protects the run and you can still use the 100A panel in your shop. You'll probably never use the full 100 Amps anyway so, you won't need to up size for the 150' run either. If you really want the full 100A service, simply up your wire by one size.
NEC changed their standard for de-rating the neutral a few years ago. Now you have to calculate the load on circuits with the neutral leg (120V in this case) as apposed to loads with 2 power legs (240V, with no neutral) so, I always run the same size wire. It's not that big of a cost until you get into 400A and bigger services.
Plus, you only bond your neutral to ground in your main panel, you don't bond it on sub panels, FYI.
I can see a situation where I'd have the lights on, the vent fan running, the oven pre- or post-heating parts, and me welding, so I'd like to stick with a full 100 amps. So, 1, 1, 1, 4 wire?
As I typically work on mobile generators and not house wiring, what do you mean by "you only bond your neutral to ground in your main panel"?
