What Huitt-Zollars does

Huitt-Zollars, Inc. is a Dallas-headquartered, employee-owned multi-discipline architecture and engineering design firm founded in 1975, operating with 501–1,000 employees across offices in 10+ US states and select international assignments. The firm delivers nine integrated service lines — Architecture, Landscape Architecture, Assessments, Construction Management, Planning, Engineering (civil, structural, traffic, MEP/fire protection), Water, Program Management, and Surveying (3D scanning, aerial drone, topographic/boundary) — to federal, state and local government, transportation, hospitality/entertainment, industrial, education, institutional, residential, and commercial clients.

Its revenue model is professional-services fee-based: project-specific design fees earned through competitive bidding on public-sector RFPs and negotiated contracts on private-sector work, with no productized software or recurring subscription revenue. Marquee credentials include design work for Walt Disney Imagineering's Grand Californian expansion, the 1.1M-SF Marriott Marquis Houston, TxDOT's statewide as-built survey across roughly 400 facilities, DART's Northwest Rail Operating Facility, NAVFAC seismic retrofit work, and Cat 5 hurricane / military rehabilitation projects. Backlog and capability are extended through programmatic acquisitions, most recently Vasquez Marshall Architects (Feb 2026, federal design-build in San Diego) and Gavan & Barker (Jun 2023, Phoenix civil/landscape). Marketing is driven by project portfolio, industry awards (ACEC Texas, ASCE, APWA, ASLA, CMAA), and conference participation rather than a digital or productized GTM motion.
