Are they supporting the house with the bolted on 2X's?
That is what it looks like. We didn't know it until they started cutting posts on Monday, but half the posts are sitting on top of the ground. They are putting extra scabbing on those. The jacking might be creating gaps. I just checked in a couple of time. I didn't watch them work, just ask how it was going.
One thing they did run into was the new deck along the river side is level, but the house isn't. They had to scab that whole side, then cut the nails loose and lift the house into level.
They are all going out of town next Monday, so we are up against a little time crunch. It's hard for me to judge, but it looks like they will not be through by then. Just three in the crew. Although they had a five year old helper this afternoon.
