This first level seems to be taking quite some time.
The fly forms (truss tables) used to pick up the concrete were created to extend out to cover the worst case at that location so that they will work for the entire tower (minus mechanical floors/roof) without modification.
As for the waving slab edges, the 90 degree archs that occur at 16 different locations on the slab edge have the same radius at each floor they just slide further and closer to the corners of the building. These curved slab edges have prefabricated steel/plywood side forms so they don't need to curve (kerf) the plywood for each floor, the radius is already set.
