Beginning with one piece of equipment used for grading farm fields and digging basements, the company by 2019 had grown to over four hundred machines and more than one hundred employees involved with concrete paving and structures, earthwork, demolition, trucking, and underground utilities.

The company also played significant roles in the BEE BRANCH restoration, Dubuque Regional Airport, Sunnycrest Manor, Highway 61/151, Dubuque water plant, and the NORTHWEST ARTERIAL.
