What STRUCTURAL CONCEPTS, INC. CONSULTING ENGINEERS does

Structural Concepts, Inc. is a privately held structural engineering consulting firm headquartered in Tucson, Arizona, founded in 1992 by Dan Lundwall and George Stevenson. The firm became fully owned by Jennifer McMahon Patronski in 2020, and operates as an SBE-certified, Woman-Owned Business with 1-10 employees. It is licensed to provide professional engineering services in Arizona, Texas, Colorado, Iowa, Ohio, and New Mexico.

The firm's service lines cover structural design and analysis for buildings, bridges, and specialty structures, supplemented by special inspections. Project sectors include municipal and public works, commercial construction, mining infrastructure, custom residential, and artistic or metal-fabrication structures. The firm has received industry recognition from the Structural Engineers Association of Arizona (SEAOA), the Associated General Contractors (AGC), and the American Concrete Institute (ACI).

The business model is fee-for-service structural engineering and special inspection work, won primarily through qualification-based selection on municipal solicitations, repeat relationships with general contractors and developers, and recurring subconsultant engagements with larger prime engineering firms. Public-sector certifications (SBE, WBE) provide preferential procurement access. No funding, M&A activity, or revenue figures have been disclosed.
