Must... remain... productive...

Although we're at a bit of an impass since we still have to get the radiant floor piping laid by Roth before we get the slab poured, we managed to do a little more work this weekend. The first thing we did was build up the next layer of the forms. We used the 2x6's that had been the insides of the footer forms and stacked them on top of the outside forms, which were still intact and anchored down with the long stakes. We also used this opportunity to recheck level. It turns out we were a little slumped in the middle of the 64' spans, probably due to the kite string sagging. Luckily we are able to make up for that our final forms, and it's much easier to check if these are level since we have a nice sturdy surface to put an actual level on. We then nailed everything together and stuffed any open cracks with some foam.

We then measured out where interior walls will eventually go, and spray painted them with neon green spray paint. Not only does this help us imagine what the floorplan of the house is going to look like, it will also be helpful when Roth comes to lay the heating pipes, since different rooms will constitute different heating zones that can be turned on and off.

We also added thermal breaks around the perimeter for where doors are going to go. It is unwise to have the slab too close to the outside as there is the potential for major heat loss, so we added in a few inches of wood at the doorways as an extra break. Basically we measured some 2x6's to be the width of the door openings, and nailed them all together.

These are the thermal breaks at the garage doors and front door.

Lastly, we prepped our drains for the slab pour. We stuffed them full of spongy foam, and then cut out solid foam caps of the correct diameter which we then duct taped over the tops of the drains. (These make a great percussion noise when you tap on them.) We also laid a wooden box in the area where the tub drain pipes will eventually go, so that that space will remain free of concrete until later when we install the tub.

I guess now we'll just relax for a few days while Roth comes in and does their work! It is difficult to be patient and wait on other peoples' schedules. But we will at least be busy with making phone calls to our mason to get the slab pour scheduled. Hopefully he's available when we'll want him - with how terrible the weather has been this summer, I expect he is very busy catching up on projects.

Updated budget:
Still the same, because all the wood used for the forms and thermal breaks was reused from before!
