Underpinning Historic Museum for U-505 Submarine Relocation
Mark R. Goudschaal
The Museum of Science and Industry U-505 Submarine Relocation project in Chicago, IL consisted of building an underground reinforced concrete vault (37’ deep) for the Museum’s new U-505 exhibit. This WWII submarine was captured in 1944, had been located outdoors at the Museum since 1954 and was lowered into its new exhibit area in 2004. A unique combination of earth retention, water cut-off and underpinning systems allowed a forty-two foot (42’) deep excavation underneath this historic museum. The museum – originally built in 1893 for the Chicago World’s Fair – was closely monitored for building movements throughout construction. The underpinning systems, construction activities and monitoring results are presented herein.
