Photos from the W yesterday, showing metal-work going in for the ACL venue.
I noticed all these angled pieces when I drove by yesterday morning. I didn't know what it was for at the time, but when I went back to look at it after work it's obvious they're for seating.
There appears to be a lower seating area (concrete) and a larger upper seating area formed by the metal beams.
Still working on the 4th floor on the tower section:
