Well, I couldn't get to the Phillyblog link above, but as far as WTC goes I ride down Delaware Avenue every night and I haven't seen anything going on at that site.
They are now placing the molds for the 8th floor of the north Waterfront Square tower.
One minute I held the key
Next the walls were closed on me
And I discovered that my castles stand
Upon pillars of salt and pillars of sand
