Actually it rotates every once in a while, sometimes to focus on 1WTC.
It rotated in my favor though. Here's a diagram(very small but in vibrant colors) of the next few months work.

-Red stands for the 24 perimeter columns being placed. Further up, maybe they will be the same color.
-Yellow stands for the crossbeams that ends the lobby and starts the mechanical floor
-White is the outline of the building.
-Green is the super large trusses shrouded in the base's glass clad curtain wall. They come in sections, because of obvious reasons. I think the Manitowoc has a high enough boom for putting those in.
*There's a truck delivering the smaller crossbeam for in between the diagonal columns right now.
