Looks like they're about to install some large white beams. Is this instead of pouring them with rebar as they have so far?
Sorry for not posting a photo but as many of you know, Photobucket now sucks. Here's the webcam link.

p.s. - Thanks for another awesome picture, jaga185.
edit: On second thought, it looks like it may be part of the core structure, or maybe a decorative entrance column for people coming in from the garage. There is a second one on the ground waiting to be installed, so I'm going with the decorative entrance columns.
