What Integrity Structural Corp does

Integrity Structural Corp is a privately held structural engineering professional services firm headquartered in Houston, Texas, with a branch office in Northbrook (Chicago), Illinois. Founded in 2002, the firm provides structural analysis, design, and construction documentation services for building construction projects delivered by licensed professional engineers (PEs) and supported by project managers, drafters, and engineering interns. Its core technology stack consists of industry-standard CAD software — AutoCAD and Revit — used to produce code-compliant structural drawings and construction documents, with particular focus on wood-frame and concrete construction.

The firm serves developers, architects, and contractors across six primary building verticals: multifamily residential (its largest segment, including garden apartments, high-density, podium, townhomes, and senior living), mixed-use developments, commercial buildings, hospitality (including brands like Residence Inn, Cambria Hotel, Hampton Inn, Hyatt Place, and Home2 Suites), worship facilities, and educational institutions. Notable named projects span a national footprint of 39 U.S. states, including AMLI Decatur, The Oliver in Houston, Cambria Hotel Austin Airport, and Rocketship Dennis Dunkins Elementary in Fort Worth. The firm is led by four Principals — John Coulson, Karla Rodriguez, Karl Miller, and Marvin Lim — with senior project management and QA functions staffed by PE-credentialed professionals.

Integrity Structural generates revenue through project-based professional services engagements priced via quote-based contracts typical of the structural engineering industry. Go-to-market is sales-led, relying on direct outreach to developers, architects, and contractors, supplemented by an online portfolio, LinkedIn and Facebook presence, and participation in career fairs and community events. The firm differentiates via talent development investments (in-house educational seminars, licensure incentives, educational institution partnerships) and community engagement (pro-bono disaster relief, MS 150 participation, Operation Christmas Child). Revenue is not publicly disclosed; headcount is reported at 59 across engineering, drafting, and administrative functions.

Broad incumbents

• AECOM: Global multi-disciplinary engineering and construction services firm with a large structural engineering practice. Competes for larger integrated commissions and on developer master-service engagements where scale and breadth matter.
• Walter P Moore: National structural engineering and diagnostics firm with significantly larger headcount and broader portfolio. Overlaps with Integrity Structural in commercial and multifamily structural design but operates at materially greater scale.
• Thornton Tomasetti: Global engineering consultancy with extensive structural engineering practice. Comparable technical offering but typically engaged on larger and more complex programs, competing for the upper end of Integrity Structural's market.

Direct peers

• DCI Engineers: Structural engineering consultancy serving multifamily, commercial, healthcare, and education across multiple U.S. states. Closest direct competitor in scale, vertical mix, and multi-state licensed-PE delivery model.
• Simpson Gumpertz & Heger (SGH): Structural engineering consultancy with broad building, infrastructure, and enclosure work. Strong direct peer on the structural design and analysis side, though larger in scale and more specialized.
• Martin/Martin: Mid-sized structural and civil engineering firm with multi-state reach across commercial, multifamily, education, and worship sectors. Closely matches Integrity Structural's project types and mid-market positioning.
• Datum Engineers: Multi-office structural engineering firm focused on building structures including commercial, multifamily, and hospitality. Comparable in service offering, project mix, and use of Revit/AutoCAD-based delivery.
• Tipping Structural Engineers: Structural engineering firm focused on building design for commercial, residential, and institutional projects. Closely comparable in services, building-type mix, and PE-led delivery model.
• Wiss, Janney, Elstner Associates (WJE): Engineering consultancy with deep structural engineering and building-services practice. Comparable in PE-licensed structural design offerings for commercial and institutional buildings, though more forensics/assessment-weighted.
• KL&A Engineers: Structural engineering firm delivering analysis, design, and documentation for building construction. Comparable in technical services, vertical mix, and PE-licensed multi-state project delivery.
