This may have been the same crew that built the form for the cement slab. They had already laid out the plastic vapor barrier when I came out the front door in the morning.
They spent a good bit of time digging out footings around the perimeter and dug the dirt away from the outside of the form as well.
Those sections of rebar are for the inside of the periodic cement-filled column of cement in the exterior wall.
I can almost tell where the rooms are going to be from the pipes sticking up in the air.
This is what it looked like at the end of the day.
