At 29 stories and more than 1 million square feet, this facility is the largest federal courthouse in the United States. Using the columns and domes that characterize St. Louis architecture, the design blends traditional and contemporary themes in a precast-concrete-clad exterior punctuated with expanses of glass.
Leonard Masonry Inc. handled the site work on this $200 million project, including all approaches to the courthouse at grade level. Leonard Masonry's crews laid the concrete block for the building's base and installed architectural concrete site walls, cast stone balustrade, granite pavers, granite steps, and cast stone planters.
Then crews moved inside to craft the building's majestic lobby. Eight columns of Italian limestone, each 34 feet high, encircle the entrance hall. The interior walls are a combination of polished, honed, and bush hammered limestone, granite, and marble panels.
