Yes, I should have included a "before" picture in my post.
It's actually hard to find a photo on the web showing the Federal Building. Here's one concentrating on the next door Dominion Public Building (also recently updated). You can see the federal annex immediately to the left.
The interesting thing is that the federal building in the photo above is already a reclad. The recladding was done about 15 years ago, but the workmanship was poor and the building was plagued by water leakage in behind the fascia. The new recladding is far superior both in terms of appearance and workmanship.
