Koss in 1912 in Des Moines, Iowa, Koss Construction Company today is a leading general contractor specializing in highway and airfield construction headquartered in Topeka, Kansas. This one-hundred years of history is the foundation that allows Koss to deliver a wide array of products and services to a multitude of owners with a consistent emphasis on safety, quality, and integrity.
