I know the tower crane is resting on the middle portion and attached to the eastern portion on Vista, but I've often wondered this on other projects..If the crane was in the center of the eastern portion, how do they remove the tower crane (boom, cab, etc) when the tower is complete?

I figured Vista would be the easiest example for me to ask this question

If the tower is in the building floorplate (like 145 S Wabash) the procedure is to take the top boom cab and stuff off either with a big mobile crane from the ground, or with a fair sized crane hoisted up by the old tower crane. After the tower crane is beheaded a smaller crane that will fit in a skip (the exterior elevators) is brought up, this will lower the mid sized rig (if it was used) and then pull up, and lower, the tower sections one at a time.

Here they are beheading the crane at 360 W Erie - for less than 13 floors or so this seems the prefered method, even when the base is not within a floorplate.

Here is one of the "smaller" cranes removing the last few sections on 465 N Park (the tower was on the outside of the building, but went through the podium).

Thanks Harry, I'd imagine that's what I'll see when they take Gr333n's crane down any day now.

Great updates today everybody!

Indeed... sitting in those atriums to get work done or relax at lunch is an unparalleled office experience.

Side note: I'm thinking of upgrading to a Panasonic Lumix G85 4K digital camera. Good purchase or anyone have other recommendations? Birthday coming up and I wanted to treat myself a little.

Look at the Sony alpha series mirrorless SLR cameras, they are awesome.

Wow, you really don't realize how many open lots and open space there is between buildings until you see it from this view!

Wow, wish I could get access to the top of the Aon Tower like that. Epic vantage point and shots.

Nick, did you happen to point the camera at other parts of the city from up there too?
