What Frankfurt-Short-Bruza Associates, P.C. does

Frankfurt-Short-Bruza Associates, P.C. (FSB) is a full-service architecture and engineering firm founded in 1945 in Oklahoma City, operating as a private professional corporation with 150+ professionals across five U.S. offices (Oklahoma City headquarters, Tulsa, Los Angeles, Mobile, and Denver). The firm provides integrated multi-discipline design services spanning architecture, structural, mechanical, electrical, civil, and fire protection engineering, alongside interior design, master planning, sustainability/LEED consulting, commissioning, construction administration, and owner's representative services. FSB serves seven core vertical markets: Aviation, Civic, Commercial, Education, Federal, Mission Critical, and Native American, with a documented portfolio that includes U.S. military hangars (NASNI, MCAS Miramar, Tinker AFB), Army Reserve Centers, university laboratories and parking structures, tribal headquarters and data centers for the Chickasaw and Choctaw Nations, and federal forensic laboratories.

FSB's revenue model is professional services: design fees and construction administration fees generated through RFP processes with federal agencies (USACE, NAVFAC, U.S. Air Force) and negotiated contracts with state, educational, tribal, and private-sector clients. Pricing is not publicly disclosed. The firm differentiates through integrated in-house multi-discipline teams, deep aviation and mission-critical expertise, LEED certification across all rating tiers (including a 52-point Platinum at MCAS Miramar Hangar 7), and 80+ years of operating history with five AIA 'Firm of the Year' awards. In May 2026, FSB entered a partnership with Colliers Engineering & Design in which FSB's senior leadership became shareholders in Colliers while preserving the FSB brand, local client relationships, and operational leadership—effectively positioning the firm as a regional node in a larger national engineering platform. No AI/ML capabilities, patents, or venture funding are disclosed; the firm's competitive positioning is anchored on human design expertise, federal past performance, and credentials rather than technology differentiation.
