For a building like this it is more economical to erect the tower crane at the final height rather than "jumping it", which is when you add more sections to the trunk of the crane. So when a mid sized building such as this is going to be erected and you do not need tower crane tie back you will just erect the crane the full height.
The crane at 1601 Vine will be jumped numerous times because of the height of the building and the need for tie backs.
