IHC Scott has a rich history of successful projects and growth in the construction industry. We have been around since 1947, and our experience shows in the quality of our work.

Originally known as Interstate Highway Construction, we began as a small construction company during the post-war era in Michigan, and steadily built a solid business based on quality and trust. IHC quickly expanded into other states to establish regional offices in Colorado and Texas.

In 2020, IHC was purchased by Clyde Companies and combined with Scott Contracting, a highly reputable contractor based out of Denver. Scott Contracting was founded in 1995 as an environmental remediation company and has continued to grow steadily and expand its operations into new areas of the market.

As IHC Scott, we provide a variety of construction services, continuing in a long tradition of putting our customers first. We offer unmatched service and quality and are committed to building a better community through every job and every region that we serve.

How we Began

How we Began

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 widening, subdivisions, basements, and installing house sewer leads, IHC grew rapidly to become one of the leading contractors building the interstate & primary highway program in Michigan.

Heading West to the Rockies

In 1976, prepared for geographic diversification, IHC won a runway reconstruction project at Denver’s Stapleton International Airport. The project was an award-winning success, influencing our decision to establish a regional office in Denver. More work quickly followed and would mark the beginning of a long relationship building for the Colorado Department of Transportation, and many other agencies in the Rocky Mountain West.


Expanding Operations Southwest ​

The Denver regional office, while maintaining its Rocky Mountain operations, further expanded in 1980 to Texas, building an early section of I-635 just north of the Dallas/Fort Worth International Airport.


Relocating to Denver

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.


The Brand New Denver International Airport (DIA) ​

By 1990, IHC had constructed over $300 million in airfield and highway projects throughout Texas and Oklahoma. As the Texas marketplace began to slow, our Texas team and resources were redeployed to Denver marking the launch of an intense five-year building program at the new $5B Denver International Airport. In those five years, IHC constructed many major components of the airfield and the airport’s surrounding infrastructure.


Crossing the Southern Border

In 1995, we teamed with Cemex, a Mexican-based material supplier, and brought slipform concrete pavement technology to Mexico for the first time. Together we built several projects in central Mexico, the most notable project being the Guadalajara to Tepic concession highway.
