H&H (Hardesty & Hanover, LLC)

What H&H (Hardesty & Hanover, LLC) does

H&H (Hardesty & Hanover, LLC) is a privately held, full-service infrastructure engineering firm founded in 1887 and headquartered at 1501 Broadway, New York. The firm delivers professional engineering services across the full asset lifecycle—planning, new design, rehabilitation, inspection, construction engineering & inspection, asset management, and emergency response—for bridges (movable and fixed), highways and interchanges, rail/transit systems, marine and port facilities, tunnels, and municipal infrastructure. Its service portfolio spans 14+ distinct disciplines organized under horizontal market segments, with proprietary tooling (HH Inspire™) supporting infrastructure asset management and lifecycle performance tracking. Customer concentration centers on public-sector transportation agencies (e.g., Port Authority of New York & New Jersey) supplemented by private infrastructure owners; revenue is generated through project-based professional services contracts procured via direct enterprise relationships and competitive bidding, with project-based fee structures. The firm operates as a lean, agile private organization with 501–1,000 employees and no disclosed external equity backing, having executed two bolt-on acquisitions (Frederick P. Clark Associates in 2019; P.E. Structural Consultants in April 2022) to broaden geographic reach into Texas and deepen bridge structural engineering capability. Go-to-market relies on direct enterprise field sales, industry recognition (ACEC-NY awards), and a multi-channel digital presence (LinkedIn, Instagram, YouTube).
