General Dynamics Electric Boat

Siefert Associates, LLC was awarded a contract by Berlin Steel at the General Dynamics Electric Boat facility in Groton, CT to help complete the construction of the South Yard Assembly Building (SYAB), the centerpiece of the biggest facility expansion in 50 years at the shipyard. This 200,000 square-foot building will eventually be home to 1,400 skilled shipbuilders who will deliver the Columbia class to the U.S. Navy. We will provide engineered lift plans for precast and steel truss erection performed by two LR 1600 crawler cranes in super-lift configuration.
