Kokosing Construction Company

What Kokosing Construction Company does

Kokosing Construction Company, Inc. is a third-generation, family-owned heavy civil construction enterprise founded in 1951 and headquartered in Westerville, Ohio. The firm operates through a network of wholly-owned subsidiaries — Kokosing Construction Company (transportation/sitework), Kokosing Industrial (heavy civil, marine, power & energy, water treatment), McGraw Kokosing (industrial maintenance and pipe fabrication), Integrity Kokosing Pipeline Services, Kokosing Materials (asphalt), The Olen Corporation and Area Aggregates (sand, gravel, limestone), and Kokosing Solar — delivering self-perform construction across the Midwest and Mid-Atlantic. Primary project categories include highways, bridges, dams and locks, water and wastewater treatment plants, pipelines, marine infrastructure, industrial plant construction and maintenance, and utility-scale solar installations. Active states span Ohio, Indiana, Kentucky, West Virginia, Virginia, Maryland, Pennsylvania, Missouri, Michigan, Washington D.C., and New York.

Business model is project-based competitive bidding on federal, state, and local government contracts alongside direct engagement with private industrial and power-generation clients. Project values range from roughly $100,000 to over $3 billion, with delivery via Design-Build, CMAR/CMGC, general contracting, and joint ventures; mega-projects are executed through long-standing JVs with Walsh Construction, Alberici Constructors, Traylor Brothers, McLean Contracting, and Plocher. Vertical integration — owned asphalt and aggregate supply and one of the region's largest heavy equipment fleets — supports self-perform execution and margins. The go-to-market is enterprise field sales through competitive procurement and qualifications-based selection.

Revenue mechanics derive from professional-services construction contracts plus construction-materials sales; no product or consumer-facing pricing exists. Customers span state DOTs (Virginia, West Virginia, Ohio, Indiana, others), the U.S. Army Corps of Engineers, transit and airport authorities (Amtrak, MARC, WMATA, CVG), municipal water and sewer authorities (Allegheny County SAN, St. Louis MSD, City of Columbus, City of Cincinnati, City of Dayton), federal clients (Arlington National Cemetery), and enterprise industrial accounts in steel, manufacturing, chemicals, and energy. Technology and operational differentiators include vertical materials supply, large self-perform craft workforce, mega-project bonding capacity, and namesake talent-development partnerships with Ohio University and Ohio State University.

Broad incumbents

• AECOM: AECOM is a global infrastructure consulting, engineering, and construction firm selected alongside Kokosing-Walsh JV on Brent Spence Bridge design. Overlaps heavily with Kokosing in design-build and construction management across transportation and water.
• Fluor Corporation: Fluor is a global EPC major with significant overlap in transportation, industrial, energy, and water infrastructure work. Substantially larger and broader in scope than Kokosing, but a relevant comparator for the most complex mega-project deliveries.
• Skanska USA Civil: Skanska is a global construction major with a large US civil division competing for many of the same mega-projects (transit, bridges, highways). A relevant incumbent comparator for pricing, scale, and project-type sophistication.
