The Koss Story

In 1912, George W. Koss founded the company bearing his name in Des Moines, Iowa. A civil engineer by education and the son of German immigrants, Koss left a secure job with the railroad to go into business for himself by pouring concrete bridges for the railroad In Iowa and across the Midwest.

Paving the way since 1912.

From our beginnings in 1912, to when automobiles began to supplant rail transportation in the 1920s, Koss adapted the company’s expertise away from concrete bridge construction into paving concrete highways.

In 2012, the Koss Construction Company celebrated its one-hundredth year of construction operations and continues to adapt to the marketplace, providing value for our clients.

The Road Ahead

The firm helped pave many of the federal and state highways across the Midwest, as the roadbuilding of the ’20s and ’30s started in earnest.  The company continued to evolve by moving into airport runways during the 1940s and postwar era. By the end of the 1960s, Koss had become one of the nation’s premier Interstate Highway contractors. The Koss role in building and rebuilding some of our nation’s most vital transportation infrastructure continues today and similar to our past, continues to create opportunities for the future generations of Koss employees.
