George Hartwell began the operations of Hartwell Excavating in 1950 as a small construction company focusing on digging basements and small utility work. In 1975, Kennaday Paving joined forces with Hartwell Excavating to create HK Contractors, Inc. As one of Idaho’s largest construction and material supply companies, we have also expanded our service area beyond Idaho Falls to include Montana and Wyoming. Through the years, we have received numerous local, state and federal awards including “Best Construction Project” for 1998, 2003 and 2004 from the U.S. Department of Transportation, Federal Highway Administration. In 2007, HK Contractors became part of the Oldcastle Materials team of companies.
