Yep. And in that case, this building's structural system will be steel rather than concrete. So instead of having a concrete frame, it'll be steel. That's interesting. Just about every building in Austin uses a concrete skeleton. This will be more like watching an old skyscraper go up. The UT Tower, Norwood Tower, Littlefield Building and Scarborough Buildings all have steel frames. The elevator core will also likely top out long before the steel frame does, so before the steel frame reaches the top, we're going to see the elevator core tower above the site for a while.
Checkout LA's new Wilshire Grand. It uses the same structural system this building will.
