The original cladding of this highrise building was an aluminum panel assembly installed over paper faced exterior gypsum sheathing and light gauge metal in-fill framing.   The rehabilitation of the in-fill sections, valued at over $2.1 million, was based on several building envelope condition assessments which highlighted the deterioration of the exterior gypsum sheathing, cladding fasteners and steel stud in-fill framing.

The rehabilitation included:

• Removal of the single-glazed window assemblies and installation of new double-glazed, Low-E, window units 
• Removal of the existing metal cladding assembly and replacement with new exterior insulated, drained metal panel assembly, including improved detailing for air leakage, water penetration and thermal performance
• New roofing membrane assembly, including increased insulation
• Structural upgrade at window openings, steel stud walls and roof parapet walls
• Improved fire resistance across partition walls at units adjacent to the hot water pipes
• Installation of new 20th floor canopies to protect exposed sliding doors
