Heavy Civil Construction History

Our company was established in 1945 by Joe, Charlie, and Bill Dunigan. We began as a small contractor in the Jackson, MI area. Since then, we have grown into one of the premier water and wastewater contractors in Michigan, Indiana and Northern Ohio.

Today, Joe’s sons—along with some of their own sons—are still actively involved in the daily operation and management of the business. For 75 years, we have been building projects, providing underground and other construction services throughout our working territory. Some of the types of work we have self performed over the past 75 years include:

  • Underground Water and Wastewater Piping Systems
  • Treatment Plants
  • Pumping and Pressure Stations
  • Site Development
  • Building Demolitions
  • Highway/Roadway Construction
  • Auger Boring
  • Mass Earthmoving Projects
  • Providing Lifting Crane Services
  • Steel Sheeting and Shoring Projects
  • Environmental Cleanup and Restoration

Our Company Today

The second and third generations of the Dunigan family have narrowed the focus from the broad range of heavy civil construction provided throughout the mid to late 1900’s. While we still provide street construction, demolition, and site work services, our primary focus is now on underground sewer and water pipe construction services. These include pressure water and sewer piping, gravity sewers, and pumping station construction.

Our extensive experience and knowledge of the underground construction industry and other heavy civil construction work have allowed us to become one of the leading underground contractors in the midwest. We have completed some of the most complicated projects from water transmission mains, water distribution systems, combined sewer separation projects, and complete new gravity sewer systems. Our experience includes complex underground projects requiring specialty pipe products, deep excavations, cast in place underground and discharge structures, river siphons, specialty shoring, and ground water management.
