The International Spy Museum (SPY) is the only public museum in the United States solely dedicated to the tradecraft, history, and contemporary role of espionage and intelligence. Open since July 2002, it features the largest collection of international espionage artifacts ever placed on public display. In 2018, the museum will relocate eight blocks south to L’Enfant Plaza, inhabiting a new $50 million building which will serve as a catalyst for transformation for SPY, the immediate neighborhood, and the Southwest Ecodistrict. The Malrite Company and The JBG Companies collaborated on plans for the 140,000 square foot facility, which will sit directly in front of the glass atrium on the Plaza.
Proposed construction increased the column loads on the Plaza by up to 2,800 kips, which necessitated retrofitting the existing foundation. SEDC’s parent company, Schnabel Engineering, was hired by JBG to work with the structural engineer, SK&A, on the retrofit design. Schnabel’s solution was to install micropiles through the existing footings, thus increasing the vertical load capacity from 1,000 to 1,800 kips. SEDC was hired to provide the construction observation oversight during the micropile load test, installation of the micropiles, earthwork, and cast-in-place concrete and grout for the foundations.
