The hotel was experiencing water intrusion due to age and deterioration of exterior wall materials. Harper-Brawner conducted investigation of the wall and window systems, including destructive investigation by removing masonry. The facility had loose and open mortar joints; failed sealants at expansion joints and the perimeter of windows and wall penetrations; and rust at steel lintels from moisture intrusion. The roof was investigated and found to remain serviceable by performing repairs.
Guestroom operable windows and balcony doors had deteriorated and were allowing air and water intrusion. Harper-Brawner conducted investigation of doors and windows by working with a contractor to take them apart to examine gaskets, weather stripping, and internal sealants. It was determined that neither windows nor doors could remain operable and be sealed from leakage. Sample installations were designed and coordinated by Harper-Brawner to verify procedures required to seal the windows in a permanently closed position and then water tested to verify non-leakage. Balcony doors that could not be permanently closed were replaced with new doors.
Masonry received extensive replacement of mortar joints (tuck pointing), replacement of joint sealants, and wet-glazing procedures between glass and frames. Cement walls received repair. Concrete and masonry received specialized chemical cleaning and treatment with a clear penetrating water repellent. Surface rust at steel lintels above windows was cleaned, lintels painted, and balcony railings painted. Small balconies outside guest rooms were no longer allowed access by guests, and were treated with a waterproof deck coating. The work was conducted without requiring rooms to be out of service overnight.
