Seattle Heights is a 26 story, EIFS-clad condominium building with four levels of below-grade parking. Shorty after construction, occupants experienced water leakage, excessive air infiltration, and apparent mold growth. SGH investigated causes and consequences of the building’s problems and designed repairs.
The condominium building features a exterior insulation and finish system (EIFS) facade with aluminum-framed windows and sliding glass doors that open onto private balconies. Three landscaped, terraced roofs cover residential units at the lower floors. For our investigation of the building enclosure, SGH:
- Performed investigations to determine problems causing leaks
- Identified defects in the design and construction of the windows, doors, balconies, and EIFS cladding
- Assisted homeowners through the litigation process to recover costs to repair construction defects
- Prepared construction documents for the repair of the building enclosure, including replacement of terraced roofs, new windows and doors, a new window and balcony deck flashing system integrated with a drainable, double-sealant joint system, and monitored the contractors’ performance during the reconstruction work
