I spoke with our builder this morning and he's planning on the following schedule right now:
Today: Prepping for one more concrete pour tomorrow (driveway apron), maybe start framing the walls.
Tomorrow: Placing concrete for driveway apron and more framing. Well driller starts on domestic water well, I think.
He doubts he will have any walls "tilted up" by the weekend (putting framing together on the ground first), but all the concrete except for sidewalks should be done by tomorrow. He said the weather is holding up great for concrete so he wanted to get the apron done to help keep mud from getting tracked everywhere once the rains hit and they are working on plumbing, electrical, etc. The apron is going to be the same length as the garage (43 feet) and extend out 20 feet in width. That will put the apron right at the edge of the aggregate driveway we have right now.
He will probably be tilting up at least some of the walls next week by the sound of it.
He figures he's got about 135+/- yards of concrete placed after tomorrow's pour. That will increase significantly once the sidewalks are added in the spring.
I took a closer look at the house slab today and saw only 2 cracks in the entire slab. Both were approximately hairline in nature and occurred in re-entrant corners, very common locations for these to occur. Given the size of the slab and lack of control joints (not put into residential floor slabs), I was impressed!
