Our Companies

McCarthy Improvement

McCarthy Improvement’s expertise in concrete and asphalt paving combined with capabilities in earth moving and underground utilities and proficiency in bridge building and repair provides comprehensive, turnkey solutions for a broad range of heavy construction projects.

Our integrated services eliminate the tangle of subcontractors, cutting costs as well as headaches. Harmonizing this efficient approach with our reliable expertise and commitment to quality is why we’ve been industry leaders for more than a century. We’ve built a solid reputation throughout the Midwest and Southeast for completing projects in the best possible way, on time and within budget.

Whether your need is single scope or wide-ranging, we provide ideal solutions for commercial and public sector projects. Private developers trust us to establish the groundwork for educational, medical and industrial facilities, shopping centers, and residential sub-divisions that often include lakes and golf courses. Public agencies rely on us for rapid completion of interstate and highway, airport, railway, and bridge projects, as well as street and sidewalk projects. Both look to us to review plans and make option recommendations.

Bush Construction

Since no two projects are identical, Bush Construction offers a variety of services and delivery methods to meet a project’s specific needs. For clients who believe a strong beginning is the best way to ensure a project’s successful completion, Bush Construction offers Preconstruction Services.

For clients with environmentally friendly goals, LEED/Sustainable Construction services are available.

We offer the following industry recognized delivery methods: Design-Build, Construction Management, and General Contracting. No matter which delivery method is best suited for a given project, it will be completed professionally and efficiently.

Clinton Engineering

Clinton Engineering specializes in the design-build, new construction, rehabilitation, and renovation of commercial, industrial, and municipal projects. Our diverse and experienced work force self performs in multiple trades; including carpentry, concrete paving, cast-in-place concrete, underground utilities, steel fabrication, steel erection, and excavation. Such versatility provides better control of project scheduling and project costs. We have an incomparable knowledge and understanding of the local landscape; including local government and codes, local utilities, and especially the availability of quality local subcontractors. Since 1926, we’ve built many of the landmark streets, bridges, and buildings in the greater Clinton area; and we have a great presence with the many industrial clients of the region. We can also turn-key metal buildings, as we are a certified STAR metal building distributor and erector.

Linwood Mining

Linwood is capable of supplying customers with a complete line of calcium carbonate, lime products, and aggregates that meet their individual specifications. In addition, a proven limestone reserve of more than 400 million tons assures that Linwood will operate at high capacity levels into the 22nd century.

Linwood originally operated as an open-cut limestone quarry. However, because of demand for the uniqueness and high purity of the company’s limestone and exceptionally pure calcium carbonate, mining was extended to an underground operation. As demand for Linwood’s products increased through the years, the company introduced new equipment and technology to accommodate expansion of the mines and meet customer requirements

AMSCO Ash Management

AMSCO takes in approved customer by-products and processes them to make a flowable fill. The fill is injected into abandoned sections of old underground mine workings to stabilize those areas for the long term.

Oertel Metal Works

If you need a custom fabrication, made of metal, Oertel works for you.

Our experience, dependability, and vision have given us the opportunity to work for customers in the mining, rail car, food service, recycling, machining, and material handling industries. However, we are open to working with anyone in any industry who needs a custom metal fabrication.  We have extensive experience in the fabrication of safety and guarding solutions, handrails, spouting, conveyors, and machinery as well as stairs and platforms for industrial clients. We have two automated plasma cutters and plate rolling and forming capabilities. If you present us with a challenge, we will design, create, and install the product the right way, on time, the first time.

Superior Minerals

We are a small sister company to Linwood Mining and Minerals that is dedicated to the efficient production of high-quality mineral fillers and granules.

We process high-calcium limestone into specified granules and powders for use in animal feed, roofing shingles, fluidized-beds, plastic, and a variety of other commercial and industrial applications. We also process steel mill slag into slag cement for various Portland cement companies.

Blackheart Slag

We process the steel slag, which is a byproduct from making steel, crushing and screening it to make aggregate chips and sand for asphalt. Much of the slag begins life as lime which is sold to SSAB by Linwood for the purification of the steel. Approximately 80% of our product is produced to go into SMA (Stone Mastic Asphalt) hot mix asphalt. With the help of our sister company, McCarthy Improvement’s asphalt division, you’re able to see our product in both Iowa and Illinois on interstate 80 over the last 4 years.
