Thanks! While researching I found out that when Mellon Bank Center was first revealed in early August 1986, the height of the spire on One Liberty Place was increased by 30 feet...while under construction! (One Liberty was up to the bottom of the William Penn statue by then) Notice that image says the height of One Liberty is 915 feet, not the current height now.

TK, I can also recall that when Cigna signed onto Liberty 2, they needed considerably more office space than the proposed tower would hold. So they shot it up to it's current height and added that huge addition (bulge) on the lower 2/3 of the tower. But that might not be all correct. Did you happen across any of that in your research?

Yes, I found everything from the 700 foot tower to the sketches by Helmut himself showing added space, and some more architectural models. You ARE correct. But this isn't the place to discuss. Should I either put it on the highrise forum or dm?

The tower crane for this one is visible on the left.
There is another (higher) crane sticking up behind CHOP. Anyone know what that's for?

There may be another tower crane going up for this? Saw it going over the Walnut Street bridge, and that's what it looked like, but I'm unsure.

You're correct, I saw them assembling it from NJ like a week ago

Nice!

It's hard for me to get a good picture, but they are currently removing the back (Schuylkill-facing) facade from the Buerger building which is necessary to connect them together.

This is starting to get a great presence on the South Street Bridge. The steel has risen really quickly.
