# HDR, Inc.

HDR, Inc. is an American design and engineering company based in Omaha, Nebraska.

## History

In 1917, the Henningson Engineering Company started as a civil engineering firm in Omaha, where HDR's headquarters remain. Willard Richardson and Charles W.

The company's first project was designing a power station for the city of Ogallala, Nebraska. Similar projects followed as the firm built water, sewer, electric, and road systems for cities and towns throughout the Midwestern United States, emerging from frontier status.
In 1983, Bouygues SA, France's largest construction company, purchased HDR for $60 million. An employee group bought back HDR in 1996 for $55 million. The company has since grown from 1,100 employees to over 12,000.

Its core services included diagnostic assessments of under-performing buildings and the management or independent validation of building engineering services commissioning. Its work in commissioning began at the Barbican Arts Centre, through all 14 phases of London's Broadgate development to the present day, including the 750,000ft2 headquarters for UBS at 5 Broadgate in London. Since the late 1990s, AR&P has successfully commissioned data centers for several of the world's most successful brands. Its design engineers were involved in work at The National Gallery from the mid-1980s when the company designed the building services for the new Sainsbury Wing, and have been involved in other museums and galleries including Dulwich Picture Gallery, the National Maritime Museum and the Imperial War Museum.

## Controversies
### Prison design

HDR Architecture's jail and prison design projects have faced criticism from advocates in the communities where the projects are proposed. In 2019, advocates in Travis County, TX opposed the construction of a new women's jail, arguing the resources would be better spent on programs to address concerns like addiction and mental health. Following community pressure, Travis County commissioners indefinitely paused HDR's $4.6 million contract to design the women's jail in June 2021. HDR also faced criticism from advocates in Massachusetts after being selected in 2021 to design a new women's prison for the Massachusetts Department of Correction. Advocates opposed all new prison construction and particularly argued against HDR's proposed "trauma-informed" design, saying it was not possible in a prison environment.

### Monitoring of activists

In August 2021, a Motherboard story detailed HDR's monitoring services provided to government agencies conducting controversial projects. The report highlighted HDR's "corporate counterinsurgency" work, especially social media monitoring, to anticipate and disrupt public opposition to projects, including highways built through sacred Indigenous sites and prison and jail construction.

## Awards

In 2018, the American Council of Engineering Companies awarded the Grand Conceptor Award to HDR and joint venture partner WSP USA for the design and construction of a new roadway within the steel-arch Bayonne Bridge—64 feet above an existing highway that it was to replace. The Grand Conceptor Award signifies the year's most outstanding engineering achievement. The recognition marked HDR's fourth Grand Conceptor in the company's 100-year history and the second time that HDR received the award two years in a row. In 2017, the State Route 520 floating bridge earned the American Council of Engineering Companies' Grand Conceptor Award.
HDR also won back-to-back Grand Conceptor Awards in 2010 and 2011. The 2011 award winner was the Hoover Dam Bypass. HDR was the project manager. The Hoover Dam Bypass won several other industry awards. The 2010 winner was the Gills Onions Advanced Energy Recovery System in Oxnard, California, which uses onion waste to produce renewable energy.
