Hardesty & Hanover

Hardesty & Hanover is a United States-based engineering firm noted for designing and rehabilitating movable bridges, long-span structures, and complex transportation infrastructure. The firm has contributed to projects across North America and internationally, collaborating with agencies and firms on iconic crossings, transit terminals, and port facilities. Its work intersects with landmark projects, government agencies, and industry peers in the fields of structural design and transportation engineering.

History

The firm traces its roots to the 19th century with early partnerships in Kansas City that later evolved into a specialist firm in movable bridge design, contemporaneous with firms involved in Panama Canal era engineering and the expansion of the Pennsylvania Railroad and the Chicago, Burlington and Quincy Railroad. During the 20th century the company expanded amid national programs overseen by the Federal Highway Administration, the United States Army Corps of Engineers, and state departments such as the New York State Department of Transportation and the Massachusetts Department of Transportation. In the postwar era the firm worked alongside major designers from projects associated with the Interstate Highway System, the Tappan Zee Bridge replacement competition, and metropolitan agencies like the Metropolitan Transportation Authority and the Port Authority of New York and New Jersey. Partnerships and joint ventures with international firms such as Arup, SNC-Lavalin, and AECOM shaped its expansion into complex rehabilitations and movable-span retrofits during the late 20th and early 21st centuries.

Notable Projects

The company's portfolio includes a variety of high-profile bridge and transit projects. Noteworthy works include rehabilitation and replacement projects comparable to the Brooklyn Bridge era rehabilitations, movable-span solutions similar to the Bascule bridge restorations on the Chicago River, and drawbridge modernization efforts akin to those on the Delaware River crossings. They have contributed to major urban crossings in the New York City region, projects near Boston, Massachusetts, and port facilities serving hubs like the Port of New York and New Jersey and the Port of Los Angeles. The firm has participated in projects involving long-span cable-stayed concepts related to designs seen in the Sutong Bridge and the Arthur Ravenel Jr. Bridge programs, and in light rail and transit terminal works linked with agencies such as Bay Area Rapid Transit, Washington Metropolitan Area Transit Authority, and Los Angeles County Metropolitan Transportation Authority. Their work has also interfaced with programs led by the National Highway Institute, the American Association of State Highway and Transportation Officials, and international clients influenced by standards from the International Association for Bridge and Structural Engineering.

Services and Specializations

Hardesty & Hanover offers services in movable bridge design, structural analysis, rehabilitation engineering, hydraulics, and mechanical and electrical systems for transport structures. Their specialization parallels practice areas emphasized by organizations such as the American Society of Civil Engineers, the National Society of Professional Engineers, and the Institute of Electrical and Electronics Engineers for bridge-related control systems. The firm provides condition assessments, fatigue and fracture evaluations, load rating, and seismic retrofitting aligned with codes from the American Association of State Highway and Transportation Officials and guidelines employed by the Federal Highway Administration. They perform project delivery methods including design-bid-build, design-build, and public-private partnership frameworks involving stakeholders like the U.S. Department of Transportation and municipal authorities such as the New York City Department of Transportation.

Organization and Leadership

The firm's leadership structure features principals and technical directors with credentials recognized by the National Academy of Engineering, the Transportation Research Board, and state engineering licensure boards such as those in New York (state), Massachusetts, and California. Senior leaders often participate in committees for the American Institute of Steel Construction, the Precast/Prestressed Concrete Institute, and standards groups under the American Association of State Highway and Transportation Officials. Collaborative delivery has seen the firm enter joint ventures with architecture and engineering firms including Skidmore, Owings & Merrill, WSP Global, and Stantec on multidisciplinary projects. Their project management and quality assurance processes are informed by practices advocated by the Project Management Institute and construction owners like the Metropolitan Transportation Authority.

Awards and Recognition

The company has earned industry recognition and awards from bodies such as the American Council of Engineering Companies, the American Society of Civil Engineers, and regional chapters of the American Institute of Steel Construction. Projects have been cited in publications by the Transportation Research Board and have received merit awards from state departments including the New Jersey Department of Transportation and the New York State Department of Transportation. Their movable bridge work has been acknowledged in case studies presented at conferences hosted by the International Bridge Conference and in technical journals associated with the Institution of Civil Engineers and the American Society of Civil Engineers.
