Corporate History (1917–2025)
HDR, Inc. traces its roots back to 1917, when founder H.H. Henningson established the Henningson Engineering Company in Omaha, Nebraska. In its early years, the firm focused on basic infrastructure for rural Midwestern communities – designing power plants, water and sewer systems, and roads for small towns. Henningson’s hands-on approach and community focus helped the company build a strong reputation regionally. By the late 1930s, two young engineers – Willard Richardson and Charles “Chuck” Durham – had joined the firm. Around 1950, Henningson offered Richardson and Durham ownership stakes, and the company was officially renamed Henningson, Durham & Richardson, Inc., giving rise to the “HDR” name. Henningson retired in 1953, after which Chuck Durham assumed the presidency and guided the firm’s expansion.
Through the 1960s, HDR diversified beyond civil engineering. It established an architecture department that quickly thrived, with notable early projects such as the Omaha Federal Building. The firm grew steadily across the United States, opening its first branch office in 1957 and developing a national profile. By the 1970s, HDR had begun taking on work overseas, opening project offices in Europe and Asia (in cities like Madrid, Rome, and Seoul) to support international projects. One significant project of this era was the Guanabara Water Project in Rio de Janeiro, Brazil – an ambitious effort to improve water infrastructure for a major city. In 1983, HDR was acquired by the French construction conglomerate Bouygues SA as part of Bouygues’ international expansion strategy. This period under Bouygues introduced HDR to large design-build projects and a broader global perspective, but the firm’s leadership soon aspired to regain independence.
In 1996, HDR’s management and employees orchestrated a buyout to repurchase the company from Bouygues, returning HDR to private, employee ownership. At the time of the buyback, HDR had roughly 1,100 employees across 21 offices. The introduction of broad-based employee ownership proved transformative, fueling rapid growth. Starting in the late 1990s and through the 2000s, HDR expanded aggressively via organic growth and strategic acquisitions. The firm has acquired over 60 companies worldwide since 1996, extending its expertise and geographic reach. Notable acquisitions included specialists in healthcare architecture, water resources engineering, transportation planning, power and energy, and environmental consulting. This strategy enabled HDR to enter new markets (such as healthcare design, mining, and economics consulting) and establish offices in Canada, Australia, Europe, the Middle East, and Asia. By the 2010s, the company was opening offices on multiple continents (for example, in China, Australia, Germany, Qatar, and the United Arab Emirates) and taking on marquee global projects like the Cleveland Clinic Abu Dhabi hospital.
HDR celebrated its 100th anniversary in 2017 as a vastly larger enterprise than its humble origins. In 2012, the company founded the HDR Foundation, a philanthropic arm funded and led by employees to support community nonprofits – underscoring HDR’s ongoing community commitment. Today, in 2025, HDR is a 100% employee-owned firm with over 13,000 employees and more than 200 offices worldwide. Annual revenues have grown to approximately $3 billion. The firm’s century-long journey has been marked by continual diversification and growth, from rural Nebraska engineering projects to some of the world’s most complex infrastructure and building ventures.
Leadership and Organizational Structure
Historic Leadership: HDR’s growth and culture have been shaped by several key leaders over the decades. Founder H.H. Henningson set the tone with his community-centric ethic and personal approach to client service. In the mid-20th century, Charles “Chuck” Durham emerged as a driving force – under his leadership as president from the 1950s onward, HDR expanded geographically and embraced innovation (even using company-owned aircraft to reach clients across the region, an unusual step at the time). Willard Richardson, the third namesake partner, also helped guide the firm’s early growth and development.
Fast-forward to the modern era, and Richard R. “Dick” Bell served as CEO from 1996 to 2011 and was instrumental in orchestrating the 1996 employee buyout; Bell’s tenure saw HDR grow from a mid-sized regional firm into a diversified, national player. Succeeding him, George A. Little took the helm as CEO (2012–2017), further widening HDR’s market reach and laying groundwork for global expansion. Eric L. Keen, a civil engineer who had risen through HDR’s ranks, became CEO in 2017. Keen led the company through continued international growth and also championed employee ownership and philanthropy (founding the HDR Foundation in 2012). At the end of 2024, Keen transitioned to the role of board chairman.
Current Executive Team (2025): Today HDR’s leadership is headed by John W. Henderson, P.E., Chief Executive Officer. Henderson, a former U.S. Army Corps of Engineers officer and Assistant Secretary of the Air Force, joined HDR in the 2020s and became President and Chief Operating Officer before being elevated to CEO in 2024. He now guides HDR’s strategy and operations worldwide. Eric Keen remains actively involved as Chairman of the Board, providing continuity and strategic counsel. The executive team also includes Neil Graff, P.E. as President and COO, overseeing day-to-day operations across all business groups. Longtime Chief Financial Officer Galen Meysenburg (CFO since 2016) manages the firm’s financial health. HDR’s organizational structure is organized around its major service lines and markets: for example, Erin Hunt, P.E. serves as President of the Water business group and Douglas S. Wignall, FAIA serves as President of HDR’s Architecture practice. These leaders, along with heads of other key sectors (such as transportation, federal programs, and energy), form an executive leadership committee.
Board and Governance: As a 100% employee-owned company, HDR is governed by a board of directors that blends internal executives with external industry leaders. Chairman Eric Keen and CEO John Henderson both sit on the board (Henderson holds the title of Vice Chairman as well). Other internal board members include the heads of major divisions (like Water and Architecture). Complementing them are independent directors such as former U.S. Transportation Secretary Mary E. Peters, who bring outside perspectives and expertise. Notably, retired CEO Dick Bell continues to serve as an outside director, providing historical insight. This governance mix ensures that HDR’s strategic direction is guided both by those deeply familiar with the company and by seasoned outsiders. Overall, HDR’s structure is relatively flat for its size, with a focus on empowering regional and practice leaders. The company operates through integrated subsidiaries (e.g. HDR Engineering, Inc. and HDR Architecture, Inc.) that collaborate closely on projects. This matrix structure – organized by both geography and service discipline – allows HDR to marshal multi-disciplinary teams for complex projects while maintaining consistent corporate values and standards.

The architecture team includes architects, interior designers, planners, and landscape architects who work closely with HDR’s engineers on integrated design projects. HDR is especially renowned for its expertise in healthcare architecture – it has designed cutting-edge hospitals, research medical centers, and specialized care facilities around the world. (For example, HDR architects have led designs for large academic medical centers and veterans’ hospitals in the U.S., as well as facilities like the Cleveland Clinic Abu Dhabi.) Beyond healthcare, HDR’s architects design civic and government buildings, educational campuses (K-12 schools and university facilities), science and technology labs, corporate and commercial developments, and cultural institutions. The firm emphasizes user-centered and sustainable design, employing evidence-based design principles (such as in healthcare settings to improve patient outcomes) and sustainable architecture practices (many HDR-designed buildings achieve LEED certification or equivalent). With the integration of firms like Rice Daubney in Australia and TMK in Germany, HDR’s architectural reach is global, and the team often collaborates across borders on design solutions.
Environmental Services
Environmental services form another core competency for HDR, often complementing its engineering and architectural projects. This service line encompasses environmental planning, science, and regulatory compliance work. HDR’s environmental professionals – including ecologists, geologists, environmental engineers, and planners – conduct environmental impact assessments, permitting, and environmental reviews for projects under laws like NEPA (in the U.S.) and similar regulations worldwide. They help clients navigate complex environmental requirements for infrastructure development, from wetlands and wildlife studies to air quality, noise, and cultural resource evaluations. HDR also provides remediation and site restoration services (cleaning up contaminated sites, designing waste management solutions, and restoring habitats). In the water resources arena, the firm’s environmental scientists work on water quality analysis and ecosystem management. Sustainability and resiliency are key focuses as well: HDR advises on sustainable design strategies, climate change adaptation, and resiliency planning for communities and infrastructure. Whether it’s designing a coastal flood protection plan, a habitat conservation strategy, or ensuring a new highway minimizes ecological impact, HDR’s environmental services group is involved at every stage to promote environmental stewardship and regulatory compliance.
Management and Advisory Consulting
In addition to traditional design services, HDR offers management and advisory consulting services to infrastructure owners and public sector clients. Branded as HDR’s Advisory Services, this group provides strategic, financial, and operational consulting to complement the firm’s technical expertise. The advisory consulting team includes over 250 professionals – some with backgrounds in management consulting and finance, others with technical and public sector leadership experience. They help clients with big-picture challenges such as developing infrastructure investment strategies, analyzing funding and financing options, optimizing programs and operations, and implementing new technologies and innovations. HDR’s advisory consultants often work in sectors like transportation, water, energy, and government programs, addressing questions like: How should a city prioritize and fund its capital projects? How can a transit agency improve its service delivery or plan for emerging mobility trends? What is the business case for a new water treatment facility or power plant? To answer these, HDR brings analytic tools (economic modeling, cost-benefit analysis, etc.), policy insight, and industry best practices. The firm’s consulting services also cover areas like asset management, risk analysis, project delivery strategy, and organizational change management for utilities and agencies. By linking technical know-how with business acumen, HDR’s management/advisory arm helps clients make informed decisions and implement solutions that are not only technically sound but also financially and operationally sustainable.
Consulting Approach and Methodologies
HDR’s consulting and advisory work is grounded in a blend of technical expertise and strategic analysis. The firm’s methodology emphasizes a holistic, data-driven approach to problem solving, especially in its infrastructure-focused consulting engagements. At the outset of any advisory project, HDR assembles multidisciplinary teams – for example, engineers, management consultants, financial analysts, and policy specialists – to ensure all facets of a challenge are addressed. They consider technological factors, economic and demographic trends, regulatory context, and community impacts as part of their planning process. In practice, HDR consultants employ techniques like scenario planning, cost-benefit and lifecycle cost analysis, risk assessment, and stakeholder engagement workshops to develop well-rounded solutions.
A hallmark of HDR’s approach is integrating management consulting tools with deep domain knowledge in sectors like transportation, water, energy, and government. For instance, in transportation consulting, HDR might use advanced travel demand modeling and traffic simulation to inform policy or investment decisions, while also applying “Big Four”-style financial analysis to evaluate funding options for a new transit line. In water resource consulting, HDR’s methodology could include hydrological modeling, climate resilience analysis, and asset management strategies to help a city plan its water infrastructure for the next 50 years. In energy consulting, HDR advisors might develop integrated resource plans for utilities by combining engineering analyses of power systems with market forecasting and regulatory scenario evaluation. For public sector strategy projects, such as advising a government agency on infrastructure programs, HDR often conducts organizational assessments, process improvement studies, and stakeholder input sessions to craft practical, implementable strategic plans.
Across all these domains, HDR’s consulting methodology stresses evidence-based decision making. The firm leverages proprietary tools and the latest technology – examples include parametric cost modeling to compare multiple design options, GIS and geospatial analytics to target investments geographically, and BIM (Building Information Modeling) data to inform asset management. Importantly, HDR believes in collaborative planning: engaging clients and community stakeholders throughout the process. Many HDR advisory projects feature facilitation of public meetings, workshops, or design charrettes to ensure that recommendations align with client goals and community needs. By uniting technical rigor with participatory planning and strategic insight, HDR’s consulting teams aim to provide clients with roadmaps that are both visionary and achievable.

The project aims to construct a high-speed train system connecting major cities of California. Since the late 2000s, HDR has provided a range of services – from preliminary route planning and environmental impact studies to engineering design for segments of the rail line. Building the first true high-speed rail in the U.S. requires overcoming complex challenges (geological, environmental, and urban constraints), and HDR has been at the forefront of developing solutions. This program underscores HDR’s role in innovative, forward-looking infrastructure. While still in progress (with initial operating segments under construction), the high-speed rail project has already yielded valuable insights in sustainable transportation planning, and HDR’s contributions to it are considered a significant achievement in engineering and project management.
- Singapore Changi Airport Projects (Singapore) – HDR (via the former Hurley Palmer Flatt team) has contributed engineering services to projects at Changi Airport, consistently rated one of the world’s best airports. In the 2010s, HDR engineers were involved in the design and commissioning of advanced mechanical and electrical systems for expansions at Changi (including airport data centers and other critical support facilities). Ensuring reliability and efficiency in an airport that serves over 60 million passengers required cutting-edge solutions. HDR’s work at Changi reflects its expertise in complex, mission-critical projects and its ability to collaborate internationally on projects that push the envelope of smart airport design.
- Coastal Resilience and Restoration Initiatives – In the realm of sustainability and climate resilience, HDR has led notable efforts such as the Dollar Bay Marsh Restoration in Texas. This award-winning project (completed in 2024) restored hundreds of acres of degraded salt marsh to strengthen natural flood buffers along the coast, enhancing both ecology and community protection. HDR’s multidisciplinary team designed innovative sediment placement techniques to rebuild wetlands and incorporated nature-based solutions to improve shoreline resilience. Similarly, HDR has been involved in urban resiliency planning – for example, advising on New York City’s coastal protection strategies after Hurricane Sandy and studying ways to safeguard rail corridors in Southern California from erosion and sea-level rise. These projects highlight HDR’s commitment to “smart” and sustainable solutions in the face of climate challenges, blending engineering with environmental science and community planning.
(The above are just a sampling of HDR’s diverse project portfolio. The firm’s work also includes many other noteworthy projects in arenas such as smart city development, major university campus expansions, iconic civic buildings, and innovative infrastructure around the world.)
