This sort of work is not done by 'a city'

Matteson Capital and Thinkbox[0] are cited as the clients by the architect AO as listed in the article

Developers take a big swing sometimes, sometimes to get interest in their proposals ( the internet likes it, so my local counsel will have to approve it ), sometimes to get attention from other partners to do big projects together. This may be a portfolio piece, even if never completed as proposed here.

I don't know much about OKC but a certain musical theatre work has me very interested in the wind loading studies for this building.
