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.

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.
