IHC began in the construction business in Michigan in 1947. This post-war and pre-Interstate era provided ample room for a small contractor with limited resources to prosper. Starting with small jobs including highway shoulder widening, subdivisions, basements, and installing house sewer leads, we grew rapidly to become one of the leading contractors building the Interstate & primary highway program in Michigan.

In 1976, looking for geographical diversification, IHC was low bidder on a runway re-construction project at Denver's Stapleton International Airport. This award-winning project led to a divisional office in Denver, further airfield work at Stapleton and the start of a long relationship building work for the Colorado Department of Transportation, and other agencies and private owners in the Rocky Mountain west.

The Denver Divisional office, while maintaining its Rocky Mountain operations, further expanded in 1980 to Texas, building an early section of I-635 just north of the DFW airport. By 1990 IHC had constructed over $300 million in projects, airfield and highway, in Texas and Oklahoma.

In 1983, the Corporate office was relocated from Michigan to Denver, leaving a local presence in the form of a divisional office in Owosso, Michigan.

By 1990, with a slow marketplace in Texas, IHC reassigned its Texas people and resources to Denver, to begin 3-years of intense activity building major portions, airside and landside, at the brand new $3 billion Denver International Airport.

In 1995 we teamed with Cemex to bring concrete pavement technology to Mexico, building projects in central Mexico and on the Guadalajara to Tepic concession highway.

We now have five operating divisions building a wide diversity of projects in the Rocky Mountain, Midwest and Southwestern United States.
