HDR is an architectural, engineering, and consulting firm based in Omaha, Nebraska, United States. HDR has worked on projects in all 50 U.S. states and in 60 countries, including notable projects such as the Hoover Dam Bypass, Fort Belvoir Community Hospital, and The Roslin Institute building. The firm employs nearly 10,000 professionals representing hundreds of disciplines in the architecture, energy, federal, water resources, environmental, mining, private land development, resource management, transportation, and water markets.

Founded in 1917 by Henning Henry (H.H.) Henningson, the Henningson Engineering Company got its start as a civil engineering firm in Omaha, where HDR's headquarters remain today. Willard Richardson and Charles W. "Chuck" Durham joined the firm in 1939 as interns. By the 1950s, Richardson and Durham had purchased shares in the firm, and it became known as Henningson, Durham and Richardson, Inc.

The company's first project was designing a power station for the city of Ogallala, Nebraska. Similar projects followed as the firm helped cities and towns throughout the Midwestern United States create the water, sewer, electric, and road systems that would help them emerge from frontier status.

Services provided by the engineering operating company are consistently ranked in the top of the Engineering News-Record Top 500 Design Firms rankings. HDR was ranked No. 9 overall in 2016. Key projects include serving as lead designer to Tappan Zee Constructors on the New NY Bridge (the Tappan Zee replacement bridge) and incorporating stormwater into an urban park at the Fourth Ward Park in Atlanta.

HDR's architecture group is known for its award-winning designs of a full range of urban environments, campuses, and buildings for clients in the healthcare, civic, justice, science + technology, higher education, and corporate and commercial fields.
