U Center configuration / upgrades
The original Rec Hall configuration had the running track, and then tall wooden bleachers that folded together - maybe 6' wide and 25' or 30' tall? These wooden bleachers effectively created a wall between the running track, and athletic areas behind them - for badminton, volleyball, etc. Those bleachers were ocassionally used for rock concerts (Elton John, Pat Benatar), graduation, and Picnic Day. It seemed a more comfy venue with that setup and keeping the sound in. There also weren't huge gaps in the upper sections for Fire Exits - exits were the four corners each with multiple doors.
The current configuration has the upper stands pushed back against the exterior wall, letting the noise escape.
The remodel - with the new upper stands - also decreased seating in the upper areas, I believe partly to create additional, closer Fire Exits. The current gaps in the upper areas didn't exist before. It was just large banks of wooden bleachers. I don't know if the ASUCD Entertainment Council or whoever gave any feedback on how it would negatively impact the ability to book large acts (bands)
They could also selectively use the upper sections - one side opened for an overflow crowd, but the other closed (folded up) so we had a full arena feel. (Not lots of empty stands.)
Adding cutouts in the cement wall between the lower and mid-tier sections was a good enhancement.
