HNTB knows the ABCs of A/E. The company is a pure design firm, which derives most of its revenues from architecture, engineering, or environmental design operations. HNTB specializes in transportation infrastructure projects and government contracts. The firm is best-known for its highway and transit system design (its portfolio includes the New Jersey Turnpike) as well as airports (Chicago's Midway) and sports arenas (Invesco Field in Denver). The company operates some 60 locations across the US. The employee-owned HNTB (its name once stood for Howard Needles Tammen & Berendoff) traces its roots to 1914.
Kansas City-based HNTB has offices in California, Florida, Pennsylvania, and Texas, and several other US states.
In 2012 the firm reorganized to create HNTB Design Build, a business the emphasized HNTB's role with private contractor partners on design-build infrastructure projects. Other areas of expertise include bridge and mass transit design, airports and storm water projects. The firm worked with the US Army Corps of Engineers and Arcadis on designing and rebuilding the levee system in New Orleans. HNTB also designed Phase II of New Mexico's Rail Runner passenger rail system. The design added 50 miles of new track for an extension of the route from Albuquerque to Santa Fe, New Mexico.
The firm is also looking to capitalize on the expected growth in toll road construction, by expanding its national toll facilities group. HNTB currently serves as the general engineering consultant to about two dozen toll agencies. – less
