What Kimley-Horn does

Kimley-Horn is a privately held engineering, planning, and design consulting firm founded in 1967 and headquartered in Raleigh, North Carolina. Operating across the United States and Canada through 155+ offices and more than 10,000 employees, the firm delivers multidisciplinary consulting services spanning civil engineering, transportation planning, environmental services, landscape architecture, program management, and construction-phase support. It serves both public sector clients — including the Department of Defense, NAVFAC, the U.S. Army Corps of Engineers, FDOT, and numerous state and municipal agencies — and private sector clients across 18+ market verticals including aviation, commercial real estate, energy, federal, healthcare and life sciences, hospitality, industrial and manufacturing, residential, sports and entertainment, transportation, and water.

The firm's revenue model is project-based professional services, with engagements scoped and priced individually per client requirements and typically structured as multi-year contracts. Approximately 90% of work originates from repeat clients, including Walmart, Home Depot, Prologis, BMW, Whirlpool, Ace Hardware, Mayo Clinic, Atrium Health, Lennar, D.R. Horton, PulteGroup, Las Vegas Raiders, Atlanta Braves, and Dallas Cowboys. Kimley-Horn also maintains a portfolio of proprietary technology products under brands such as DRIVE (program management), the Traction suite (smart-cities mobility), Kadence and KITS (smart-cities infrastructure), PV Tune (solar PV optimization), TREDLite VMT (transportation analytics), XAK-PACK (water infrastructure), PublicCoordinate (community engagement), and SMARTS (program management). Marketing is primarily relationship-driven, supplemented by industry awards, project case studies, conference participation, and webinars.

The firm's go-to-market combines direct enterprise and government sales with event-driven pursuit of large public-private partnerships, including recent pursuits such as the $6.8B Gas Plant District redevelopment in St. Petersburg and the Atlanta Beltline Southside Trail. Growth has been supported by targeted tuck-in acquisitions — RGD Consulting Engineers (MEP, March 2026) and Gamble Design Collaborative (landscape architecture, April 2026) — alongside expansion into adjacent technology-enabled services such as autonomous vehicle infrastructure planning (with Waymo, Beep, Adastec) and robotic sidewalk accessibility assessment (with Daxbot). The firm holds #1 ENR rankings in Retail, Multi-Unit Residential, and Distribution & Warehouses, and has appeared on the Fortune 100 Best Companies to Work For list for 19 consecutive years.
