Quality Since 1925.

Valley Construction Company was founded in 1925 here in the Quad Cities.  Today the Hass family still owns and operates the family business, self- performing earthwork, utilities, paving, structures and building construction. We are customer focused, striving to build relationships built on integrity, performance and trust.  Our desire to serve our changing customer base has molded a turn of the century company into a responsive and flexible general contractor. We employ a project management philosophy of comprehensive planning, scheduling, and project execution. We are proud of all our accomplishments and strive to exceed our customers expectations of quality, timeliness, and value.

John, Jim, Bill Hass

The opportunities of today are a direct result of the strong foundation created by John, Jim and Bill Hass. The Hass brothers managed Valley Construction Company for nearly 50 years, growing and expanding the company their father, Arthur Hass, founded in 1925. John, Jim and Bill are responsible for the company’s growth and success through good economic times and bad. Their vision and strategy to diversify and execute multiple company acquisitions allows for the multi-faceted approach to client satisfaction that Valley Construction Company currently provides. 

Our History

What began in the early 1920’s as one determined man with a single piece of horse-drawn equipment has grown into one of the most well-known and well-respected construction firms in this region. Arthur J. Hass founded Valley Construction Company in 1925 and that first small project helped to establish the foundation for a company that has over 85 years of steady, safe and respected growth. Into its third generation of Valley leadership and fourth generation of contractors, the Hass family owns and operates the company that now performs grading, utilities, structures, industrial, bridge and building construction, in addition to its original paving capabilities.  

Valley Construction Company seeks to continually build on its rich history of using the latest construction technologies more safely and with more value than any of its competitors. Both private and public clients continue to demand more from contractors and Valley continues to stay ahead of those demands with investments in personnel, equipment and technology. Valley is proud of its accomplishments and is committed to upholding its award winning reputation and tradition of providing superior client satisfaction and supporting the communities we work and live in, leading it into another century of success.
