What Ajax Building Corporation does

Ajax Building Company, LLC is a Florida-domiciled, privately held construction management and general contracting firm founded in 1958 by J.B. 'Block' Smith and now operating under third-generation Smith-family leadership. The company is a subsidiary of STO Building Group (joined 2018) and is structured as an employee-owned firm. Ajax delivers projects across the Southeastern United States from 14 offices in Florida, Georgia, and South Carolina, serving institutional and public-sector clients in K-12 and higher education, government, public safety, healthcare, cultural, justice, life sciences, and historic restoration sectors.

Core service offerings include Construction Management at Risk (CMAR), Design-Build, Agency Construction Management, Public-Private Partnerships (P3s), and full preconstruction-through-close-out lifecycle delivery. Underlying technical capabilities center on Virtual Design & Construction (VDC/BIM) with laser scanning, a Safety 360° behavior-based safety program partnered with OSHA Consultation Services at the University of South Florida, and sustainable-build expertise spanning LEED, Green Globe, and Georgia Peach certifications. The firm has 24 LEED Accredited Professionals on staff and holds ABC STEP Platinum, OSHA SHARP, and Zero Incident Rate credentials, with a 2025 EMR of 0.55 and TRIR of 0.00 (Ajax only).

The revenue model is project-based professional services: fee-based construction management, CMAR at-risk delivery, and general contracting on a competitive-bid and relationship basis. Go-to-market is enterprise field sales via direct project bidding, CMAR/Agency CM contracts, and design-build partnerships with institutional owners; distribution is supported by 14 physical offices that enable local-market bidding. The customer mix is heavily institutional, with an 85% repeat client rate and disclosed cumulative contract wins exceeding $4.35 billion across K-12, higher education, and public safety verticals.
