I was originally thinking this is a view from Irving, as you can see a foundation at the base of the facility. But what is the tall building behind the arena then?
That surely has to be the new hotel.
Note that the terrain slopes from right to left. That would also only make sense if this view was looking west, towards I 81.
Looks like they added support columns to the north and south, where the load bearing walls are. You can see an expansion on the northeast corner of the building.
I am assuming they are showing how the eastern wall on and above the 200 and 300 sections will be open to light via the use of EFTE. Cool. Probably won't be able to do it on the west side because of the hotel.
No expansion on the southeastern corner on this drawing, which differs from the other one.
Surprised at the relative flatness of the roof. Looks like they are planning to use EFTE in the triangles formed between the steel, facing north and south. I would think this design would allow snow to pile up...thought EFTE was going to be used a lot more to help encourage the snow to slide off (like in Minneapolis).
Sure looks like they are not planning on expanding the concourses on the north and south sides of the facility. There will be no new concourse on the third level either.
It will be a really strange look with an uber modern roof, some open walls and a huge expanse of drag concrete on the sides. Hope they decide to address this in a phase 2 project down the road.
