Here is my first ever photo update! I've been a long-time viewer, but I rarely post. These pictures were taken on my personal day trip to Philly yesterday.
These photos show how large and bulky the core really is and the presence of it relative to its surrounding. Can't wait to see the steel wrap around it. Not just the height but the overall size of this building will be daunting and impressive to say the least.
That's the 250 ton Kobelco crawler crane that assembled steel base and West side TG1900 tower crane. It has been moved around to East side of site to erect heavy base columns and second TG1900 which will be an internal climbing crane.
But i never said anuthing about which city was better (which is an idiotic conversation to start with) . . . only that in terms of size/height, CITC can't really compare with Aon out Hancock. Decorative lanterns notwithstanding, they win hands down.
I understand what you mean, I was talking just aesthetics...I love Chicago
If interested in crane being assembled now check out the Ping An International Finance Centre in Shezhen under Suprtall Construction forum and go to post #338. Two collars will support static height for crane and then a third collar will be installed and by use of two climbing ladders the crane will climb itself to higher elevation. After climb the lower collar will be repositioned for next climb phase. First time in states for this method perhaps.
