Perry and Associates

What Perry and Associates does

Perry & Associates LLC is a Chicago-based structural and architectural engineering consulting firm founded in 1999, operating as a privately-held Illinois LLC from its headquarters at 221 N. LaSalle St., Suite 3100. The firm provides a unified portfolio of professional engineering services—including general structural design, adaptive reuse, failure analysis and forensic engineering, specialty engineering (earth retention, physical security), litigation support, building enclosure and waterproofing design, and architectural engineering—delivered by licensed structural engineers and architects. It serves architects and building designers as its primary customer segment, alongside building management companies, private businesses, and individuals throughout the United States.

The firm's underlying "technology" is professional engineering expertise rather than a software platform; its proprietary capabilities rest on deep, hands-on experience across modern and historic construction types and materials, with services spanning new design, renovation, repair, investigation, and expert testimony. Service delivery is conducted project-by-project through direct client engagement, with no software product, API, SDK, or app component disclosed.

The business model is fee-for-service professional consulting with project-based pricing negotiated per engagement; pricing is not publicly disclosed and no alternative pricing models (subscription, retainer, licensing) are offered. Go-to-market is conducted through a single marketing channel—the company website—supported by direct sales to enterprise and individual clients. The firm is independently owned with no parent company, subsidiaries, external investors, or publicly traded securities disclosed, and operates from a single Chicago office serving projects across the U.S.
