It's definitely the Harris Bank Building plus the east annex. I got it right away this morning but didn't bother logging in to comment. Then again I've been in the building a few times and worked more frequently in the Field Building next door. It's interesting seeing this plan that when the annex was built all of the egress stairs were relocated into it, leaving none in the original building.

I've always found the connection between the buildings at the back to back elevator banks rather awkward.
