HDR, Inc. is a U.S.-based company specializing in design and engineering, with its main office located in Omaha, Nebraska.
History
Originally established in 1917 as Henningson Engineering Company in Omaha, the firm transformed following the arrival of Willard Richardson and Charles W. "Chuck" Durham in 1939. These partners eventually took ownership and renamed the business Henningson, Durham, and Richardson, Inc. Early on, the company concentrated on infrastructure developments such as power plants and municipal utility systems throughout the Midwest.
In 1983, HDR was purchased by the French construction corporation Bouygues SA for $60 million. However, an employee-led buyback occurred in 1996 for $55 million, after which HDR experienced significant growth, expanding its workforce from approximately 1,100 to more than 12,000 employees.
Acquisitions
Following the buyout, HDR has completed over 60 acquisitions worldwide to diversify its services and extend its market presence. Notable acquisitions include:
- Cooper Medical (2011), which enhanced HDR’s capabilities in integrated healthcare design and construction within the United States.
- Schiff Associates (2011), a firm specializing in corrosion engineering with multiple offices across the U.S.
- HydroQual, Inc. (2011), broadening expertise in water resource management with locations domestically and in Dubai.
- Amnis Engineering Ltd. (2011), reinforcing hydropower consulting services both within Canada and internationally.
- TMK Architekten • Ingenieure (2013), establishing a European center focused on healthcare and scientific facility design; this subsidiary was divested in 2023.
- Salva Resources (2013), an Australian-based provider of mining exploration services operating globally.
- Sharon Greene + Associates (2013), adding proficiency in transportation economics and financial analysis.
- Rice Daubney Architects (2013), expanding HDR’s offerings in healthcare, defense, retail, and commercial sectors across Australia and worldwide.
- MEI, LLC (2015), strengthening LNG-related engineering and consulting from Georgia.
- CEI Architecture (2015), enhancing architectural and interior design services in British Columbia.
- Maintenance Design Group (2017), complementing HDR’s infrastructure lifecycle approach through vehicle fleet facility planning expertise.
- David Ford Consulting Engineers (2018), augmenting water resources knowledge including hydraulics and flood risk assessment.
These targeted acquisitions have significantly bolstered HDR's competitive positioning across diverse industries such as healthcare, water management, transportation, mining, and energy, facilitating global expansion and sustained business development.
Hurley Palmer Flatt
In July 2019, HDR increased its footprint across Europe and Asia by acquiring Hurley Palmer Flatt, a British engineering consultancy along with its subsidiaries. The acquired entity was rebranded as HDR in early 2022.
Founded in London in 1968 by John Hurley, Hurley Palmer Flatt specialized in mechanical and electrical engineering consultancy services. Over time, it expanded internationally with offices in Dubai, India, Australia, Singapore, and the United States, serving both governmental and private sector clients.
To grow its market share strategically, Hurley Palmer Flatt made several acquisitions: ATCO Consulting was acquired in 2009 to strengthen operations in Scotland; in 2014 it acquired majority ownership of Andrew Reid and Partners (AR&P), a London-based firm recognized for commissioning major projects including London's Broadgate development and UBS headquarters. AR&P also contributed to prominent cultural sites like The National Gallery and the Imperial War Museum.
In 2016, Hurley Palmer Flatt secured a majority stake in Bradbrook Consulting—a civil and structural engineering firm with offices throughout the UK and Dubai. That same year saw the relocation of its London headquarters to 240 Blackfriars at South Bank Tower under a decade-long lease to support business growth ambitions.

Prison design
Projects involving jail and prison design by HDR Architecture have encountered resistance from community groups. In Travis County, Texas, activists opposed plans for a new women’s detention center in 2019, advocating instead for investment in addiction treatment and mental health services. Under public pressure, the county suspended HDR’s $4.6 million contract related to the jail design in 2021. Likewise, in Massachusetts, HDR’s selection in 2021 to design a women’s prison attracted criticism from advocates who reject new prison construction and questioned whether HDR’s "trauma-informed" design approach could be effectively applied within a correctional environment.
Surveillance of Activists
In August 2021, a report by Motherboard brought to light HDR's provision of monitoring services for governmental bodies, emphasizing its role in "corporate counterinsurgency." This included tracking social media activities to predict and hinder opposition to initiatives such as highway construction through Indigenous lands and the development of detention facilities.
Awards
HDR has been honored with several Grand Conceptor Awards from the American Council of Engineering Companies (ACEC), celebrating exceptional engineering accomplishments. In 2018, HDR, alongside partner WSP USA, received the award for the Bayonne Bridge roadway project. This marked HDR’s fourth Grand Conceptor accolade and its second consecutive win, following the 2017 recognition for the State Route 520 floating bridge. Additionally, HDR secured consecutive awards in 2010 and 2011 for notable projects like the Hoover Dam Bypass—where it served as project manager—and California’s Gills Onions Advanced Energy Recovery System, which transforms onion waste into sustainable energy.
Miscellaneous
HDR maintains operations in all 50 U.S. states and extends its reach to 10 countries worldwide. Its portfolio includes significant projects such as the Hoover Dam Bypass, the Alexander T. Augusta Military Medical Center, and the Roslin Institute facility. With a workforce exceeding 12,000 experts across various fields, HDR stands as the fifth largest employee-owned enterprise in the United States, generating $2.8 billion in revenue during 2022. According to Engineering News-Record, HDR ranked as the sixth largest design firm in the U.S. in 2023.
