I stopped by the site this afternoon to find that Mark had welded in the first floor joists, and set up the second floor joists on the bedroom side of the house. Most of them are bolted into place, with the remaining joists waiting to be welded.
Yesterday evening, Brock went out to the property to help the crane guy, who came to pick up his crane. As long as they were out there, they used the crane to lift the remaining floor joists onto the second floor, which made today's job easier. No pictures of that, since it got dark during the process.
That's all there is to report. We didn't talk to Mark today, so not sure what he's planning next.
