We were just at BWV last week, alot of work was being done on floor 2 in the 2040-2050 range maybe a bit more. This hallway, if coming from check in, is to the right straight across from the elevators. Overall it wasnt bad, but on a couple days it was quite loud, not from the workers themselves so much, but from very large fans and dehumidifiers they placed outside of about 10 rooms. i dont know if they broke a pipe while working or what, but our impression was they were definately trying to dry something up
the rest of the hall they were working on was without a ceiling and covered by cloth, didnt look all that pleasant but wasnt too bad overall
we didnt mind since the fans in the doorways gave us a good opportunity to peek in and check out a bunch of rooms
