The steel has not been erected on the west side because we are erecting the red steel for the atrium first. Boston02124 posted a pic of one of the tree columns (

It has a huge canopy that will eventually go on the congress st side. we are erecting the rest of the atrium now and after that is done the rest of the building sits on top of the atrium. All of the missing steel ties in to that.
I'll post some pictures soon.
