Equipped To Get The Job Done

IBI’s fleet of equipment includes all the machines and vehicles needed to build the most difficult job—even in the tundra conditions of midwinter. We have heavy trucks, cranes, dozers, loaders, packers, pumps, welders, generators, light plants, temporary heaters, ground thaw systems and literally thousands of pieces of equipment needed to build projects safely 12 months a year. That’s why we continue to be one of America’s most successful construction companies – because we don’t stop to let the weather pass.

Versatility, organization, safety and performance. The IBI way.

Our History

Warren and Irene Diederich founded Industrial Builders, Inc. together in 1953 with a passion for developing infrastructure in the Midwest and the dream of building a legacy that would serve their region for years to come. They had four children who all began careers with IBI in the 1970's. Paul and Donn, two of their sons, have lead the company as President and Executive Vice President, respectively, since 1992 and the third generation of Diederich family is involved in the company now. Warren and Irene started the company with as a family business where all employees were considered part of the family. IBI has grown substantially since Warren and Irene started it up but it's still a very tight knit community and we're proud of everyone that is a part of it.

When we started, our scope of skills was mostly limited to bridge work, but as Warren and Irene became involved with the Associated General Contractors (AGC), IBI began to change and enter new sectors. Paul and Donn have served as executives both at a state and national level in the AGC. Paul served as President of the National AGC in 2013 and Donn served as Chairman of the Highway Division in 2017. Consistent involvement in the AGC has allowed IBI to stay ahead of and influence trends in the construction industry.
