Renovation of this 12-story, 198 unit senior housing project was completed in multiple phases while remaining fully occupied. Tenants were relocated one floor at a time so that units could be renovated with new plumbing fixtures, tile, paint and carpet. Common areas and corridors were also upgraded with new finishes. The exterior renovations included new windows and sliding glass doors, and concrete flatwork with parking upgrades to accommodate ADA compliance. Upgraded building systems included a new hydronic mechanical system with boiler, electrical and lighting systems, and fire alarm system. Tight clearances in plumbing chases, and the ever-present safety concerns related to elderly residents were some of the challenges that required constant diligence.
