These are the only other ones I've seen on the internet showing the construction of the One American Center.





Notice that in this next photo 816 Congress was also under construction and the One American Center hadn't come out of the ground yet. I guess they must have been digging for a while for the parking levels because the next photo shows 816 Congress appearing complete while they were still working on the first few floors of the One American Center. The next photo also shows 1005 Congress and the Capitol Center under construction.
