    Grunley to Renovate 1785 Mass. Avenue, NW to Serve as New AEI Headquarters

    Grunley has been selected by the American Enterprise Institute for Public Policy Research (AEI) to renovate and restore 1785 Massachusetts Avenue, N.W., Washington, DC to serve as its new headquarters building.

    Located in Dupont Circle, 1785 Massachusetts Avenue, N.W., is a National Historic Landmark built in 1917. It originally served as a luxury apartment building and home to Andrew Mellon, its most famous tenant. AEI purchased the property from the National Trust for Historic Restoration.

    The construction budget to renovate 1785 Massachusetts Avenue, NW is $40 million.

    The renovation of this five-story historic property will involve excavation, underpinning and construction of a new level below the existing basement. A new central core structure will be constructed up through the building and the existing steel frame will be reinforced to accommodate a new penthouse level. New mechanical and electrical systems will be installed in the existing historic spaces. The façade will undergo complete restoration of the highly detailed limestone work.

    For the past year, Grunley has been providing preconstruction services to AEI and its designer, Hartman-Cox Architects. These services have included assistance with developing the scope of work and construction documents in addition to budgeting and pricing. The construction budget is $40 million. Grunley will begin work onsite in November 2013 and will continue through August 2015.
