The orange steel beam assembly is the armature deck from which the wall forms are "hung" and allow the outer panels to roll back to set reinforcing. These outer panels are being set even as I write this. The whole deal gets pushed up by hydraulic cylinders that are attached to the previously poured wall below--they are inside the forms in what will be the elevator shafts.

Oh, and the 500 ton crane that will erect the tower crane is being set up now. Saturday evening-Sunday morning looks for the crane to be going up.
