Ironworkers: "raw" construction footage #1 from Ⓗ Week 55

Iron workers assembling the structural steel frame of the building. Usually I speed things up, time-lapse style, but every so often I include some original "raw" construction footage at original speed with original audio. This video was also in Ⓗ series Week 55's Weekly Time-lapse, but there it was sped up with music, whereas here it is at original speed with original audio. I use the term "raw footage" loosely. It is not completely un-edited — the footage has been color-corrected, for example. By "raw" I mean the footage has just been minimally edited, with no attempt to "tighten it up" or "tell a story" or any of those kinds of editing processes. On this channel, we're following the construction of a new 12-story hospital that will occupy an entire city block in San Francisco. This video is from Ⓗ series construction week 55.
