One-week construction time-lapse w/over 42 closeups: Ⓗ Week 56: Ironworkers; welders; cranes; more

In this "Ⓗ series", we're following the construction of a new 12-story hospital that will occupy an entire city block in San Francisco. This is Week 56 of the series. This is a construction time-lapse at 900x, with over 42 highlights/closeups at various speeds scattered throughout, compressing the one-week period from July 20 - 24, 2015 into about 33½ minutes. Non-working days and nights are omitted.

We don't see as much of the iron workers this week, as a lot of that activity is on the other side of the building from us. We see a fair amount of the flames and sparks of the welders, and lots of "things being lifted by tower crane". There is equipment driving in the street, and, just after we finally learned it's purpose a couple of weeks ago, that red cage is taken away.
