The west stairway prototype installation on floors 13, 14 and 15 is essentially complete. The west stairway will be open from now until June 25, when construction is expected to resume. The full barrier system should be installed by mid-September. Work will then move to the east side stairs, which will be closed from mid-September until the end of December.
