One-week construction time-lapse w/over 40 closeups: Ⓗ Week 67: Ironworkers; cranes; welders; more

Week 67 in this "Ⓗ series", in which we're following the construction of a new 12-story hospital that will occupy an entire city block in San Francisco. This is a construction time-lapse at 900x, with over 40 highlights/closeups at various speeds scattered throughout, compressing the one-week period from October 5 - 10, 2015 into about 37 minutes. Non-working days and nights are omitted. This week, in addition to the usual ironworking, welding and general construction activities, the construction site gets a visit from an air show. This is one of those rare construction time-lapses that includes military jets, I'm guessing that is not a common thing.

I know I'm using the same music for all of these weekly time-lapses, but there's too many of them and they're too long to license different music for each one. You are of course free to turn down the volume and provide your own accompaniment music! There's no dialogue or other audio in these weekly time-lapses, just music.
