HDR Acquisitions and Global Strategic Growth
Since transitioning to an employee-owned firm following a buyout from the French conglomerate Bouygues in 1996, HDR has pursued an aggressive growth strategy. By acquiring over 60 firms worldwide, the company has evolved from a regional player into a global powerhouse in engineering, architecture, and consulting.
HDR's acquisition strategy focuses on diversifying its technical capabilities and expanding its geographic footprint, particularly in the healthcare, water, and transportation sectors. This growth allows the firm to offer a full life-cycle approach to infrastructure development, integrating design, construction, and long-term maintenance.
Key Facts
- Scale: Over 60 firms acquired globally since 1996.
- Key Sectors: Strong focus on healthcare, water resources, transportation, and energy.
- Major Global Expansion: Significant growth in Europe, Asia, and Australia through strategic mergers.
- Notable Integration: The acquisition of Hurley Palmer Flatt significantly expanded its multidisciplinary engineering presence in the UK and beyond.
Strategic Expansion in Healthcare and Water Resources
HDR has consistently strengthened its specialized service lines through targeted acquisitions. In February 2011, the firm acquired Cooper Medical in Oklahoma City, creating HDR Cooper Medical to provide integrated design and construction delivery for healthcare facilities. This was followed in March 2013 by the acquisition of TMK Architekten • Ingenieure, a German firm that served as the hub for HDR's European healthcare and science design programs until the subsidiary (HDR GmbH) was sold to employees in 2023, becoming Telluride Architektur GmbH.
Water resource management has seen similar growth. In January 2011, HDR acquired HydroQual, Inc., which brought nine offices across the U.S. and Dubai into the fold, and Amnis Engineering Ltd. in Vancouver, specializing in hydropower infrastructure. Later, in 2018, the firm added David Ford Consulting Engineers in California to enhance its expertise in water hydraulics and flood risk analysis. Most recently, in February 2022, HDR acquired SPF Water Engineering and its BIM (Building Information Modeling) service provider, MDS Drafting.
Diversification into Transportation and Energy
To complement its infrastructure portfolio, HDR has acquired several firms specializing in transportation and energy. In July 2013, it integrated Sharon Greene + Associates for transportation economics, and in September 2017, it acquired Maintenance Design Group to improve its vehicle and fleet operations planning.
Recent expansions in the Southwest United States include the 2021 acquisitions of WKE, a multimodal transportation engineering firm, and WRECO, which provides innovative engineering solutions for California communities. In the energy sector, HDR acquired the assets of MEI, LLC, a liquid natural gas consulting firm, in January 2015.
The Integration of Hurley Palmer Flatt
One of HDR's most significant expansions occurred in July 2019 with the acquisition of Hurley Palmer Flatt, a London-based multidisciplinary engineering consultancy. Established in 1968, Hurley Palmer Flatt provided mechanical and electrical engineering services across the UK, Dubai, India, Australia, Singapore, and the US. The firm was rebranded as HDR in early 2022.
Hurley Palmer Flatt brought with it a history of its own acquisitions, including ATCO Consulting (2009), Andrew Reid and Partners (AR&P) (2014), and Bradbrook Consulting (2016). AR&P was particularly notable for its work in commissioning and diagnostic assessments for high-profile projects like the Barbican Arts Centre and the UBS headquarters at 5 Broadgate.
Notable Projects and Recognition
Through Hurley Palmer Flatt and AR&P, HDR inherited a portfolio of prestigious projects and awards. Key projects include the Weston Library at Oxford University—which won the RIBA National Award 2016 and was shortlisted for the Stirling Prize—and the Singapore Changi Airport.
The firm's expertise also extends to cultural institutions, with AR&P contributing work to The National Gallery, the Imperial War Museum, and the National Maritime Museum.
