What Corna Kokosing does

Corna Kokosing Construction Company, doing business as CK Construction Group, is a privately held general contractor founded in 1956 and headquartered in Westerville, Ohio. The firm provides comprehensive design-phase and construction-phase services across all standard delivery and contractual methods, organizing its work around nine end-market verticals: cultural, health and wellness, commercial, education and research, government, manufacturing and logistics, mixed-use and housing, sports and entertainment, and transportation and aviation. Its project portfolio includes the Controlled Environment Agriculture Research Complex (CEARC) at Ohio State University, multiple projects at the Columbus Museum of Art and Easton Town Center, the Columbus Crew Training Facility, the Franklin County Forensic Science Center, and the Kennedy Engineering Building at Ohio Northern University. The company has expanded selectively beyond Ohio into adjacent Midwest markets, most recently with the Gateway Park Health & Wellness Center in New Palestine, Indiana.

The business operates on a project-based, quote-driven revenue model in which each engagement is individually scoped, priced, and contracted, typically on multi-year timelines. Go-to-market is direct enterprise field sales, targeting project owners, architects, and development partners primarily in the Columbus metropolitan area and broader Midwest region. Customer mix is diversified across sectors but skewed toward repeat institutional and commercial anchor accounts (e.g., Ohio State University, Columbus Museum of Art, Easton Town Center, Franklin County, Columbus Crew). The company has earned 10 consecutive Best General Contractor and 4 consecutive Top Workplace awards from Columbus CEO, multiple BX Craftsmanship Awards, and the 2025 American Architecture Award from The Chicago Athenaeum for the CEARC project, which collectively support its regional brand position. No proprietary technology, software platform, or AI/ML capability is disclosed in the source material; the value proposition is grounded in craftsmanship, culture ('The CK Way'), and execution rather than technology differentiation.

• Clark Construction Group: Large ENR Top-10 GC with strong institutional, healthcare, education, and sports/entertainment portfolio — comparable delivery but operates at materially greater scale than CK.

Direct peers
