Sherman Building

Located at the Armed Forces Retirement Home in Washington, D.C., the Sherman Building was constructed in three phases between 1852 and 1891. The building is the centerpiece of the site's National Historic Landmark status.

The 2011 Mineral, Virginia earthquake caused significant damage to the building, including dislodging parapet stones through the roof into classrooms below and onto adjacent cars and leaving the iconic clocktower in a state of near-collapse.

Working as a project manager for Keast & Hood, Craig Swift led post-earthquake structural assessments, repairs, and retrofits to the building, including a signature effort to reconstruct the clock tower with a steel frame work hidden from view.

Craig co-published an ASCE paper entitled "Evaluations, Repairs, and Retrofit of the Historic Sherman Building in Washington, DC, following the 2011 Mineral, VA, Earthquake" and presented the project at a 2015 ATC/SEI Conference in San Francisco, California on Improving the Seismic Performance of Existing Buildings. 

The project team was recognized with numerous awards, including the 2014 State Historic Preservation Officer Award in the DC Awards for Excellence in Historic Preservation (video embedded at left)!
