In 1947, Herbert R. Imbt founded a small construction company in State College, Pennsylvania with only a few pieces of equipment.  During the following decades, HRI, Inc., as the company was later renamed, expanded geographically to cover areas outside of central Pennsylvania, including much of Central, Eastern, and Western Pennsylvania.  Operations also expanded to include paving, water, sewer, airport, highway, and bridge projects as well as asphalt plants and aggregate quarries.

In 1999, HRI, Inc. was purchased by Colas, Inc., a worldwide leader in the construction industry, with numerous construction businesses throughout the United States.  Today, HRI, Inc. benefits from being part of a much larger organization while still maintaining local control over our activities and the close ties to the communities we serve.


WE ARE a diversified construction company with expertise in highway, airport, water, sewer, treatment plants, bridges, and paving.  We have the resources, management, technology, and equipment to deliver quality projects on time.

WE SERVE the communities in which we live and work through diversified public and private markets within Pennsylvania, West Virginia, Maryland, Virginia, Ohio, North Carolina, South Carolina, Georgia, and Alabama. 

WE VALUE safety, the environment, and our most important asset, our employees.
