Firm Notes
This was the successor engineering firm to Harrington, Howard and Ash, Kansas City, MO, formed in 1914. Howard Needles Tammen and Bergendoff has been headquartered since 1941 in Kansas City, MO, specializing in transportation, bridges, aviation, architecture, urban design and planning, environmental engineering, water and construction services. It made its reputation in the field of transportation design, creating roadways, airport runways and bridges.
HNTB combined with the Kansas City-based architectural firm, Kivett and Myers, in 1975 to form an architectural design firm focused on sports venues. Kivett and Myers had gained wide attention in the 1970s for its design of the Harry S. Truman Sports Complex (consisting of Arrowhead Stadium and Kauffman Stadium) which opened in 1972-1973.
In 1982, HNTB purchased the Boston-based rail transportation consulting firm, Thomas K. Dyer, Incorporated, founded in 1963 by rail engineer Thomas Keane Dyer (1922-2002).
The firm became reorganized within the larger HNTB Corporation in 1993. The architectural section within this larger engineering, construction and design firm was HNTB Architecture, Incorporated. Employee ownership occurred in 2002.
