Barndominium/Shop or "real" House?

At least you know that you have your base rock compacted really well!!!!

I have always seen sub-slab work done before the building goes up, not afterwards. It what you are doing the norm in your area? Or is there some other reason for doing the building first, and floor second?

Yes. On a post frame, the building goes up before the slab. The weight of the structure is transferred through the columns into the footers. The slab is poured around all the columns. This is standard practice here.

Speaking of the columns, I asked the Amish crew to not backfill them with the sandy load soil, they did anyways. So now I have to dig that soil out and replace with crusher run.

That soil just will not compact with the jumping jack, the foot just disappears into the soil and the whole area floats, it's still too wet and I don't trust that the soil will stiffen up anytime soon.

For the first concrete pour, I have to do this for 27 columns...

Getting ready to run the pex for the garage slab. Wondering if I should or should not run pex under the stairwell?

Seems like it might get too hot in there, this will be all one heat zone.

I would agree as it appears that's where the PEX is terminating (under the stairs). Also will the water heater for the radiant hear go under the stairs too? That area is in the middle of the building too, so it will get residual heat from the surrounding slab.

Can you valve off the stairwell for future use/non-use? Now's the time to install it. You'll have a tough time going back.

The boiler will be on the upper level, so not on the 1st floor. Under the stairwell will be a 7-branch manifold collecting all the loops from the garage and workshop.

My take is that part of the concrete will get somewhat heated by the adjacent loops.

I could put in another single loop manifold and some tubing if I ever needed to heat that area but is that really needed? Could I just add tubing to the bottom of the stair treads in the future if I ever wanted to heat the area above the stairs?

Are you going to be crawling or laying or walking barefoot under the stairs? That is the only way you will notice the concrete is not heated. Jon

There will be a door to the under stairwell cavity. What will be in there is the main water shutoff, and the 7-branch manifold. That's pretty much it.

I don't see myself going in there very often.

The issue is really if the stairs leading up to the second level need to be heated or not...
