The construction project across State Street will be dong heavy pile-driving work on Tuesday, 9/11/07. While we don't expect it to have an impact (pun intended) on vibration levels at BNC, that possibility does exist. Please be aware of this potential issue. Thank you for your patience, John John R.

That will occur a couple of blocks away from where you are. It shouldn't be all day and I don't know if you will even hear anything or not, but I want to make you aware.
