I didn't realize UNLV was a tenant, but that (2 fields) would certainly add complexity ETA: LV has swiveling columns,,,,,woo hoo! we better get some of those. Pony up Virginia $$$$$$$$ essentially, because of the seating load they need columns that can move and allow the tray to pas by, but that means other columns have to take up the load (and said other columns also swivel!!!). It is more complicated then Phoenix, but that's why rich people build stadiums (or taxpayers) and we sit and marvel at it all I'm confused as to what exactly holds up the load while the swiveling ones are swiveled. A temporary set of columns? And why can't those just be permanent? (these are somewhat rhetorical questions, please feel free to just respond "engineering magic and crossed fingers") I'm not entirely sure, but I think the entire seating area pivots out of the way for the tray to pass through the building opening. The swivels could be mounted on rollers that allow the columns to roll with the seating section above/ like a table on casters so to speak. Def engineering magic however, back to Dan the Man Campbell, his super intendant threatened to kill my client 2 times. Once we began the legal proceedings to have him removed from eh project, Dan lost his license...magically. I wont go into the details, but essentially his business partner left him (and his partner had the license under which we were working) and POOF no more company. We were lucky to finish the project. If you have ever seen "Casino", the house we were working on was 8 houses down from Lucky's place:
