What Mosser Construction does

Mosser Construction is a private, 100% employee-owned (ESOP) construction management and general contracting firm headquartered in Maumee, Ohio with a second office in Fremont, Ohio. Founded in 1948, the company has delivered approximately $3.5 billion in cumulative project value over 77 years and employs between 501 and 1,000 people. It serves institutional, public-sector, industrial, and energy clients across Ohio and the broader Midwest, with named projects including the Oregon Clean Energy Combined Cycle Power Plant, Bowling Green State University's Hanna-Maurer Center, University of Toledo's Interprofessional Immersive Simulation Center and Savage Arena, the ODOT Lorain County I-90 New Interchange, and the Collins Park Water Treatment Plant. Service markets explicitly enumerated by the company include Energy, Highway & Bridge, Higher Education, Industrial, K-12, Public, Recreation, Renovation, and Water Treatment.

The company's service portfolio centers on Construction Management and General Contracting, augmented by Preconstruction services (value engineering, site selection and assessment, budget estimating, scheduling, design-phase leadership, financing assistance, subcontractor/bid control), a Design/Build delivery method that enables accelerated schedules by overlapping design and construction, Self-Performing capabilities for direct control over critical trades, BIM (Building Information Modeling) for 3D coordination, and LEED consulting for sustainable projects. The operating model is sales-led with direct enterprise field sales targeting large institutional and industrial buyers, supplemented by marketing through AGC/OCA industry leadership, project case studies, client testimonials, and community engagement.

The business model is professional services revenue generated through project-based contracts. Pricing is determined during the preconstruction process through value engineering, budget estimating, and subcontractor bidding rather than published rate cards. There is no disclosed annual revenue, no external funding, and no parent company; ownership is held entirely by employees through the ESOP. Affiliated but separate entities, Telamon Construction and Contractors Equipment, extend the operational footprint into additional construction capability and equipment supply.

Broad incumbents
