About Us

For more than 50 years, McAninch Corporation has been a leader in the grading and underground utility industry. A family-founded and employee-owned company, McAninch is recognized as an Iowa Top Workplace. Whether it's providing the groundwork for massive data centers or extensive underground utility work for water, sanitary and storm pipes for residential and industrial areas, McAninch delivers exceptional service and unparalleled quality for its customers.

Why McAninch

Specializing in large-scale mass grading and underground utility for projects in the public and private sectors – from residential and commercial developments to highways, industrial parks and flood-control levees – McAninch has earned a reputation as one of America’s foremost site civil contractors. We work with Midwest-based companies or global companies expanding to the Midwest. No project is too large for our team of talented employees to successfully navigate and bring to fruition. Likewise, if a smaller project is the job-at-hand, we manage it with the same level of precision and thoroughness.

Private-sector developers trust McAninch to lay the groundwork for office parks, shopping centers, industrial facilities, data centers and housing subdivisions that often include additional features like lakes and golf courses. In many cases, we collaborate with owners and developers as the engineering plans are developed. Public-sector agencies count on us to rapidly complete things such as large highway projects, flood control levees and airports.

McAninch is nationally recognized as one of the most technologically advanced earthmoving contractors. Since the 1980s, we have served as one of Caterpillar's beta sites to test new components and machine configurations. Engineering faculty from colleges and universities around the country consult with us on soil technologies, and our personnel are active in National Association of Government Contractors industry-advancement efforts.

Who We Are

As a family-operated company since our founding more than 50 years ago, and an employee-owned company since 2023, McAninch is a team of people who pride themselves on getting the job done – on time and within budget while achieving the highest quality standards.

When it comes to mass grading, McAninch Corporation is the best contractor in the area. We are a one-stop-shop for grading and underground utility projects. We deploy heavy equipment for many different job sizes, and our fleet of lowboys and maintenance vehicles can quickly mobilize to sites. To maximize productivity from our resources, we have invested heavily in GPS machine guidance and other advanced technologies to improve job efficiency, accuracy and quality.

Underground utility installation is one of our specialties. Each season, McAninch coordinates many pipe-laying crews on projects that often involve installing sanitary sewer lines, storm sewer lines, underground structures and watermain systems. In this demanding, specialized arena, McAninch is known for our speed, safety and uncompromising quality.
