Could be that its a cast-in-place concrete garage too, but you wouldn't need a tower crane for that unless the city of Denver is not allowing them to shut down a lane for the crane access for the next several months to lift formwork and other miscellaneous items.

A couple of the Skyhouse parking decks have been built with standard concrete pouring. The Charlotte one, IIRC, is a good example of that and they had a separate tower crane for that one too.
