What to plan/install prior to slab pour

[Dreamshop]

So the shop will be under construction within the next 3 weeks. Looking at the entire project has given me hives so I'm trying to break it down into bite size pieces. My first piece is the pre-pour. Here's what I have so far:
- pad for shed (being moved in behind the garage)
- underground conduit from shop pad to shed pad for power
- Conduit in shop for gas, water, hydro, Ethernet
- floor drain
- insulation/pex/side pad insulation for heated floors
- perhaps a pad for the exterior man doors? (Outside)
- drain heat tracing wiring?
- grounding rods by panel location

Is there anything else I should consider or have missed?

Thanks!

Drain for the condensate from a high-efficiency boiler.
Thick spots for potential lift.

I forgot the drain from the boiler! I did however plan 2 4' x 4' pads that will be an additional 12-18" deep for the 2 post lift

Anchor bolts for for attaching the walls. They can be pushed into the wet mud. Or they can be hung from a stick attached to the form.

Oh yes. They are spec'd out as part of the engineered slab.

- grounding rods by panel location

You don't put ground rods in the slab. You can put a "Ufer" ground in the slab and stub up the rebar near your panel location.

Take a look at my Guide to Floor Slabs in the link below for some thoughts on the slab itself. Just like the stuff under the slab, you only get one chance to get the slab right. Good luck with your project.

Are you going to apply any sort of an epoxy coating on the floor? If so, coordinating with the proper cure/sealer will make your life easier.

Along that lines, what sort of a textured finish do you want for the floor? Slick, broom, etc.

Expansion joint placement and type?

Lastly I’d clarify if there are any curbs or stem walls. My current house drives me a bit mad. There is a soft rolled curb of sorts vs hard angles. It makes it difficult to roll anything flush to the wall.

If your heavy into auto repair consider putting a couple of 'pull pots' or anchor points in the pad.

I add 1" conduit going from one side of the building to the other. That makes it possible to get a 60A wire from one side of the building to the other without going around.

I also typically add 3" sweeps to each corner and the middle of the foundation. "Future Use" conduit.

"I also typically add 3" sweeps to each corner and the middle of the foundation. "Future Use" conduit." Can you explain what you mean here?

I am a truck and car mechanic by trade. But unless I'm doing body/frame repair is it necessary?

Only you know the way you work and if it is worth the investment. An anchor point can be used to drag in dead cars or other pulling projects. More than a few times over the years I've wished I had one.

Not sure where you are located, but a vapor barrier under the slab would prevent moisture from coming up

Pre-plan where you are washing off the tools / concrete truck chute. And controlling the runoff.

My last shop I mounted 4 receiver hitch tubes in the floor in a 10 foot square. Came in very handy for future projects

Vapor barrier, 2” blue board, pex for future radiant heat, drains for a bath or at least a utility sink and toilet.

That's a neat idea!

Floor safe

Anchor Pots (use floor plates if installed at pour).

Rebar and mesh.

So if I'm using the dimpled floor insulation with pex and 32mpa concrete with fiber mesh, should I lay WWM over the insulation/pex?
