Looking at the site last week, 48 sections of colunns, 120 beams to be place between the columns and the bracing is needed to get to the top of the existing building. The photo above show 12 of those columns in place now.
Looking west and the rendering, the extra floors will step back one bay at both ends, leaving 5 bays for the tower. Looking north, the rendering show something different, but support wise will see one bay on each side as step back, leaving 3 bays for the tower. About 60' x 100' floor slab
It's odd not seeing the old skin on the building.
Waiting to see what happens for the roof area.
