Tutor Perini Corporation is a diversified construction services company that provides general contracting, construction management, and design-build services to private and public customers globally, with particular expertise in large-scale infrastructure, buildings, and specialty trade systems. The company operates three primary segments: Civil (focused on mass transit, highways, bridges, tunnels, and water infrastructure), Building (serving hospitality, healthcare, commercial, and technology sectors), and Specialty Contractors (providing electrical, mechanical, plumbing, and HVAC systems). Tutor Perini generates revenue primarily through fixed-price and guaranteed maximum price contracts for government customers (federal, state, and local agencies), and maintains a competitive advantage through vertical integration of self-performed services including earthwork, concrete forming, steel erection, and mechanical systems installation.
