The crane at 1601 Vine will be jumped numerous times because of the height of the building and the need for tie backs.
I sort of figured this was done to save time and money. I hadn't thought about how you can only do this with cranes of a certain height that don't require additional lateral bracing to the building structure as it rises. Seems to be the same deal at East Market and the Dalian.
