What THP Limited does
THP Limited is a privately held structural and architectural engineering design firm headquartered in Cincinnati, Ohio, founded in 1973 and operating across four U.S. offices (Cincinnati, Cleveland, Raleigh, Northern Virginia). The firm delivers four integrated service lines — Structural Engineering, Restoration & Waterproofing, Building Envelope, and Parking Consulting — serving institutional and commercial clients in Higher Education, Healthcare, Public Facilities, Commercial, and Industrial Manufacturing. Core technical competencies include post-tensioned cast-in-place concrete design (particularly for parking structures), SPRAT-certified rope access building envelope assessment, masonry and waterproofing restoration, and 10-year prioritized master planning for parking infrastructure. The firm has delivered notable large-scale projects including the $600M Cincinnati Children's Hospital Critical Care Building, the $265M University of Kentucky Healthy Kentucky Research Building, the $180M CVG Airport ConRAC facility (4,300 stalls), and Kentucky's first Parksmart Bronze-certified garage.
The firm's business model is professional services, project-based, and quote-driven. THP generates revenue through engineering design fees, condition assessments, restoration consulting, and construction administration services, typically structured as a percentage of construction value or fixed project fees. The go-to-market motion is enterprise field sales — direct engagement with owners, architects, and construction managers — augmented by thought-leadership content, industry events, and earned media (Cincinnati Business Courier rankings: 13th in engineering, 23rd in architecture regionally). The firm maintains an employee-shareholder ownership structure, with new shareholders announced in October 2025, and shows no external private equity or venture capital backing.
Customer concentration skews toward higher education and healthcare systems in the Midwest and Southeast, with marquee repeat clients including the University of Cincinnati, University of Kentucky, UC Health, Cincinnati Children's Hospital Medical Center, St. Elizabeth Healthcare, and Hamilton County. THP has cultivated long-tenured relationships — Sinclair Community College parking restoration has run since 2009, and the firm has produced multi-year master plans for Parking Authority of River City's 15 garages. The firm is expanding geographically into Northeast Ohio and North Carolina while cross-selling its newer building envelope practice, which generated $2.83M in 2025 billings alone.
