How SIS supports the Corps' mission
The U.S. Army Corps of Engineers builds and maintains flood risk management, navigation and military construction projects nationwide, and contracts much of that work to private firms. Its districts in the Midwest manage levees, pump stations, locks and dams, reservoirs and installation work across thousands of miles of river.
SIS has delivered for four Corps districts: Kansas City (KC Levees pump stations), Rock Island (PL 84-99 levee repairs and Mississippi River riprap), Louisville (the Weldon Spring Reserve Center gas conversion) and St. Louis, where our headquarters sits. That range gives us working knowledge of Corps specifications, submittal procedures, three-phase quality control and EM 385-1-1 safety from the prime contractor's seat.
