Federal and industrial construction in St. Louis.
Our Granite City headquarters is minutes from downtown St. Louis. We build for federal agencies, plants and utilities across the metro.
SIS has served St. Louis since 2002, first supplying valves, fittings and process piping to plants such as Anheuser-Busch InBev, then performing civil work for the Metropolitan St. Louis Sewer District and federal work across the region.
Recent St. Louis-area federal projects include Building 65 masonry repairs for the Missouri Air National Guard at Jefferson Barracks and the natural gas conversion of the Weldon Spring Army Reserve Center in St. Charles County, finished four months early for the Corps.

Federal construction across Metro St. Louis
Metro St. Louis has one of the heaviest concentrations of federal facilities in the Midwest: the Corps of Engineers' St. Louis District, Jefferson Barracks and its Missouri Air National Guard units, VA medical centers, federal buildings and courthouses, the National Geospatial-Intelligence Agency's NGA West campus, and Scott Air Force Base across the river in the Metro East. Add the levees, locks and pump stations along the Mississippi and Missouri rivers, and there is a steady stream of repair, alteration and civil work.
SIS is 15 minutes from downtown St. Louis. Local crews and an in-house procurement desk mean shorter mobilization, faster response to site issues and lower travel costs on small and mid-size federal projects.
