I walked by the HH recently and construction of the exterior (which is presumably done before the interior) is still unfinished. The Kimpton is part of the same skyscraper complex (other building, though, it is in a low rise in front of the two high rises) and open. I am staying there in a few weeks.

As for your other question: The Kennedy 89 has a presence on LinkedIn which lists 15 staff members. You should find a suitable contact there.
