Yes, there was work being done on a Saturday. I watched them lay the sheathing for the porch and garage extension roofs. 99% of the brick has been laid, all except for the upper right corner.
I'm having them frame and drywall over one of the windows in the basement because it conflicts with where the projector screen will go. This picture shows the 5.1 surround sound wiring, and the projector drop in the ceiling. It also shows where they've treated the framing to prevent termites (it's the green stuff you see for the first 2 feet or so of the wood)
So I seem to have sprouted a new window. It doesn't bother me though.
They've filled in more holes with spray insulation. You can also see where they have caulked between boards.
There are quality assurance notes written and marked in orange all around the house. Again, you can see more caulking between boards.
I'm pretty sure they use spray insulation in the wall cavities, but in the attic, I guess they use conventional insulation. I'm not sure if there's a code that says that the sprinkler line must be below the insulation. (That's what it looks like they did at least)
