The structural engineering for the National Museum of African American History and Culture, the long-awaited Smithsonian Institution situated on the National Mall in Washington, D.C., was done by two engineers teaching at Princeton University’s School of Architecture. Guy Nordenson of Guy Nordenson and Associates — Professor of Structural Engineering and Architecture — served as structural engineer for the building’s superstructure while Nat Oppenheimer of Robert Silman Associates New York — Visiting Lecturer in Structural Engineering — served as structural engineer for the building’s substructure. The architect, David Adjaye, also taught at the Princeton University School of Architecture for several years. The museum is slated to open to the public on Saturday, September 24th.
