AAA Royal Construction has completed the replacement of nearly 900 windows within the Garrison Square Apartments in Boston’s Back Bay. The complex $3M project included the supply and install of a series of windows that needed historical approval within Boston’s St. Botolph Architectural Conservation District along 56 St. Botolph Street. Along with the new windows, AAA Royal also created a custom, mahogany front entry door system for the project and manufactured custom historic exterior metal trim panels for above each window. Not only did this project present complexities because of the varying sizes of the windows, but, install had to be completed within occupied units. For this project, AAA Royal invented an exterior window replacement safety system for units above the first floor that allowed workers to caulk, insulate, and clean windows from the exterior of the building, eliminating the need for expensive boom lifts and staging. This saved the owners tens of thousands of dollars in construction costs. AAA Royal Construction worked with the property management staff to ensure minimum disruption for residents of this high-end complex, completed an on-time and on-budget project, all whilst maintaining a safe working environment with strict protocols to protect residents during the COVID-19 worldwide pandemic.
