It appears that they have excavated the south half of the site to depth and they are preparing to build the base for the crane. Don't get too excited...the crane is not here yet. They are drilling massive pilings in the exact location of the elevator shafts so I can only assume this will be for the crane.
I will try to take some pics in the next week if I remember to bring my SLR so as not offend Cutterp with my cappy phone pics.
