We have basement walls!
We also have a ton of mud. We left with some of it still attached to our shoes. Blech.
In other news, I met with our PM today and the plumber was on site doing his thing. PM explained the two-level foundation...apparently you have to dig at least two feet to get to undisturbed ground, and two levels keeps them from having to build a 12 foot high wall without supports. The space under the "great" room and morning room half of the house will be filled with gravel prior to the slab being poured. We also lucked out in that the plumber says we won't need a sump pump or ejector pump (for the sewer, I think?) because everything will be able to drain via gravity.
The current plan is to pour the slab on Friday, and hopefully they can start on framing as early as Monday!
