Concrete parking garages are heavier on a per column basis than just about any other type of building, so not that surprising to have deep caissons.
RyanD said its not a precast concrete garage, so the crane may just be there to lift formwork, rebar, and the concrete pump into place. Otherwise, there really is no reason for a tower crane on a parking garage, because you can drive or carry your equipment and materials up as you finish the ramps and new levels.
And if it were precast, I have never seen a tower type crane used with enough lifting capacity to lift those very heavy concrete pieces. Doesn't mean they aren't out there, I have just never heard of it before (and I have worked on quite a few precast garage projects). Guess we'll find out soon enough!
