What Sunesis Construction Company does

Sunesis Construction Company is a privately-held heavy civil contractor founded in 1991 and headquartered in West Chester, Ohio. Operating as a wholly-owned subsidiary of Sunesis Holdings, LLC, the company self-performs all major aspects of heavy civil construction across Ohio, Kentucky, and Indiana, serving both public sector owners and private commercial clients. Its work spans eight integrated service divisions: Marine Infrastructure, Earthen Retention, Bridges & Structures, Roadway & Concrete Pavement, Underground Utilities, Wastewater Treatment Plants, Site Work & Property Development, and Design-Build.

The company's technical stack centers on capital-intensive owned assets and modern construction technology rather than software IP. Its fleet includes crawlers, all-terrain cranes, GPS-equipped dozers and graders, sheet piling, and beams, supplemented by 3D drone imaging for earthwork tracking and state-of-the-art estimating, project management, and scheduling software. DOT certifications in Ohio, Kentucky, and Indiana qualify the firm for state transportation work; depth-of-scope capabilities (piping 6"-96" diameter, shored excavations 5'-50' depth, retention systems to 48') support technical bids on complex projects that smaller subcontractors cannot self-perform.

Sunesis generates revenue through project-based, competitively-bid construction contracts with individual awards ranging from roughly $125,000 to $7.35 million. Pricing is quote-based per project; there are no standardized pricing tiers. The go-to-market is direct enterprise sales into public agencies (ODOT, INDOT, KYTC, municipalities, park districts, airport authorities, sewer districts) and private owners (national GCs such as Messer, Turner, Skanska, Kokosing; corporations such as UPS, DuPont, Norfolk-Southern; universities; and sports venues). Diversified operating subsidiaries under the Holdings umbrella (Environmental, Properties, Container Services) extend the revenue base beyond core civil work, but financial details are not publicly disclosed.
