The steel superstructure is being used for the entire seating bowl. I am too lazy to find the article on here in order to give the link, but I definately remember the article stating the steel has arrived on site and most of the upper deck seating will be done by April.
I have no knowledge of how other arenas have been built and have no structural engineering experience either, but my best guess is that it is almost necessary to use steel for a structure like this, due to the multi-layered seating structure.
It is nice to see the steel structure there and on the other two current big construction projects; Three PNC and the North Shore Casino. I have looked at almost every construction thread on here and I would estimate that more than half are going up with concrete. Let's consider it a little tribute to our past....
