For the guys above (oldschool, Mass_) or anyone who might know, I'm curious who makes certain design changes (specifically improvements) along the way (and, though I expect it's entirely specific to the project, why).
Looking at the Calgary Library here:
https://competitions.org/2014/12/2014-12-22-23-36-52/
vs. the end result of the library, I noticed that the hexagonal facade was carried around the entire building in the end, wherein the render the south-facing side of the building doesn't have it and there is a more "standard" looking window treatment above the arch on the west side. There are also some other minor changes throughout,
I know this doesn't have a lot to do with the arena, I just know this render isn't going to be exactly what it looks like. And I know what happens when it goes the opposite way (where the render looks great while the building turns out like crap), but I'm curious how the library actually turned out better (in my opinion, obviously).
