Quantum Consulting Engineers

What Quantum Consulting Engineers does

Quantum Consulting Engineers is a Seattle-based structural engineering firm founded in 2002 that provides consulting design services for new and existing buildings. The firm designs in structural steel, light-gauge steel, concrete, post-tensioned concrete, masonry, and wood, and delivers four core service lines: structural engineering (new design, renovations, historic preservation, adaptive reuse, tenant improvements, shoring, and repairs), seismic engineering (hazard identification, vulnerability assessments, retrofit, and emergency response), structural value engineering (peer reviews, constructability reviews), and shop drawing production for structural steel fabrication and erection. The firm's client base spans architects and design firms, property developers, government entities (Port of Seattle, City of Bellevue, City of Kent), private homeowners, and industrial/manufacturing clients, with recurring affordable housing work for Low Income Housing Institute and a multi-year seismic engagement at Sea-Tac International Airport.

The firm is owned and led by three principals — John Riley, Sandro Kodama, and Scott Tinker — supported by four associates (Frank Unocic, Samson Ng, Amanda Johnson, Travis Michaud), and is privately held with no external institutional investment. Quantum is licensed in 47 US states and parts of Canada, and has developed niche domain specializations including seismic retrofit design, historic preservation, sustainable/green building certifications (Living Building Challenge, Passive House, LEED), and unusual structures such as climbing walls (80+ designs with Vertical Solutions) and treehouses (15+ designs with Nelson Treehouse and Supply). The business operates as a project-based professional services firm with quote-based, scope-determined pricing and a GTM anchored in direct engagement with architects and developers, complemented by a project portfolio website, LinkedIn/Instagram presence, and industry award visibility.

Revenue mechanics are not publicly disclosed. The firm's customer concentration is moderate by virtue of repeat institutional clients (LIHI, Port of Seattle, Seattle-area municipalities) balanced across multiple verticals including government, nonprofit, higher education, K-12, enterprise retail/automotive, beverage manufacturing, and industrial. Strategic posture is steady-state organic growth with selective leadership promotions (most recently Travis Michaud to Associate in January 2025) rather than acquisitive or capital-raise-driven expansion. No AI/ML capabilities, no proprietary software products, and no patents are evident; differentiation rests on talent, licensure breadth, regulatory expertise, and a multi-decade portfolio of award-winning projects.
