Sadly, 625 West Adams, the 20-story office building from White Oak Realty and CA Ventures, topped out last week.

Let me explain. Of course, topping out is a huge milestone, and should certainly be celebrated. But it also means the days of that pretty yellow Liebherr tower crane right outside the B.U.C. HQ are numbered. Sadder still, 625 topped out while we were in London, so after countless hours of staring out the window at progress, I missed the soiree.

Power Construction was kind enough to share the photo above, taken as the last beam was lifted into place on Monday, May 22.
