Renovation and Restoration of a DC Landmark

Originally constructed in 1924 and expanded in the 1960s, the Neo-classical headquarters of the National Academy of Sciences required extensive updating to modernize building systems, accessibility, and functionality. Revit^® was a critical tool, enabling Mueller’s engineers to route new mechanical/electrical systems throughout the historic structure, including challenging, constricted spaces. Engineering highlights encompassed extensive new sustainability and energy conservation measures and equipment, including the introduction of building-integrated photovoltaics.

The building was also expanded to improve circulation, add meeting areas, and improve access for visitors entering the public galleries and auditorium. The project, which is highly visible along Constitution Avenue, won many awards, including the D.C. Award for Excellence in Historic Preservation.
