I don’t know where this talk about the foundations is coming from, but I’d like to hear about it. I don't post much but have a lot of firsthand knowledge of the stadium's design. I personally helped design TCF Bank Stadium's foundations and various other components. I just looked at the plans again and saw the third deck concept and can say that the foundations were designed for future expansion. Since the stadium’s foundations are piles and not footings, it was critical to get those in place since getting a pile driving rig inside the building later would be a virtual impossibility.
