Founded as the Riggs-Linthicum Company in 1909, our original charge mission was to represent manufacturers in the sale of materials for “buildings, railroads, and other purposes.” Over the years, Riggs Distler helped construct some of the most notable buildings in the United States, including the Empire State Building, the U.S. Supreme Court, the Federal Reserve Building, the Library of Congress, the Internal Revenue Service headquarters, The Breakers Hotel, the National Constitution Center, and hundreds of power plants, government facilities, refineries, and industrial facilities throughout the eastern United States. In 2021, we joined Centuri Group, Inc., a comprehensive utility infrastructure enterprise serving gas and electric providers across North America.
