Smithfield Foods has selected Chicago-headquartered Epstein as design-build contractor in a $1.3-billion packaged meat and fresh pork processing facility it's planning to build in Sioux City, S.D., a 1.1 million sq ft project that the South Dakota Governor is calling the largest business investment in the state’s history. The new facility is planned for Foundation Park, a more than 1,000-acre heavy industrial park in northwest Sioux Falls.
