Onyx Design and Consulting

What Onyx Design and Consulting does

Onyx Design and Consulting is a private structural engineering firm headquartered in York, Pennsylvania, with regional offices in Arlington, Virginia and Baltimore, Maryland. The company delivers professional structural engineering, Building Information Modeling, laser scanning, special inspections, forensic engineering, and steel connection engineering services to government agencies, architectural firms, building owners, general contractors, and trade subcontractors throughout the U.S. East Coast. Technical delivery is anchored in Autodesk Revit and Tekla Structures for BIM, laser scanning for as-built data capture, and an in-house AISC-compliant steel connection design tool that the firm has used on projects of up to 7,000 tons. Project work is concentrated in K-12 and higher education, multi-family residential (including affordable and student housing), civic/cultural, and adaptive-reuse sectors.

The firm operates on project-based professional services revenue, with scope and pricing determined per engagement rather than via disclosed unit pricing. Distribution is direct enterprise sales conducted from three regional offices, supported by thought-leadership content marketing (technical blog, weekly newsletter), industry conference attendance (e.g., Bluebeam XCON), and community involvement. Customer logos skew toward public-sector K-12 modernization and new-construction programs and Mid-Atlantic multifamily developers, indicating concentration in education and residential use cases.

Onyx is led by Managing Principal Timothy Park and operates with a professional staff licensed across more than a dozen U.S. states via NCEES records, enabling rapid licensure in additional jurisdictions. The firm is privately held with no disclosed external investment, no parent company, and no subsidiaries. Founding date is reported inconsistently across data sources (2009 in firmographics, 2020 in company history), with the firm's own marketing claiming more than 10 years of structural engineering experience.

Direct peers

• Wiss, Janney, Elstner Associates: Employee-owned structural and architectural engineering consultancy with deep expertise in structural design, forensic investigation, and special inspections — directly overlapping Onyx's core service portfolio, especially forensic engineering and failure investigations.
• Silman Structural Engineers: Structural engineering consultancy with strong East Coast presence serving cultural, institutional, education, and adaptive-reuse clients. Highly comparable in project-type mix (historic preservation, cultural, education) and use of BIM-led delivery.
• Simpson Gumpertz & Heger: Engineering firm specializing in structural design, building enclosures, and forensic/ investigative work. Closely comparable on structural design + forensic + special inspections service mix, with strong East Coast presence similar to Onyx's footprint.
• T.Y. Lin International: Global engineering firm with a major structural engineering practice covering buildings, bridges, and special structures. Comparable in core structural design and BIM-led delivery, though significantly larger and broader in transportation infrastructure.
• Thornton Tomasetti: Global structural engineering firm providing design, forensics, and BIM-led delivery across buildings and infrastructure. Highly comparable in service mix (structural design, BIM, forensics, steel connections), though it operates at materially larger scale than Onyx.
• KL&A Engineers and Builders: Structural engineering consultancy providing design and connection engineering for buildings, with a focus on steel-heavy commercial and institutional work. Closely comparable in size, service mix (structural + steel connection engineering), and project-type alignment.
• Raths, Raths & Johnson: Mid-sized structural engineering and architecture firm focused on structural design, investigation, and repair of existing buildings. Closely comparable to Onyx in forensic engineering, special inspections, and rehabilitation work for aging and historic structures.

Broad incumbents

• Arup: Multidisciplinary engineering consultancy with a leading structural engineering group covering buildings, sports, and cultural projects. Comparable in BIM, complex structural design, and East Coast project footprint, but operates across many disciplines beyond structural.
• Burns & McDonnell: Large employee-owned engineering, architecture, and consulting firm with a structural practice serving government, education, and commercial clients. Comparable in government and K-12 structural work, though materially larger and broader in scope than Onyx.
• WSP USA Buildings: Major engineering consultancy with structural engineering and BIM services for buildings, including government and education clients. Comparable client overlap (public agencies, schools, developers), though WSP is a broad incumbent across many engineering disciplines.
