HARDESTY & HANOVER CONSTRUCTION SERVICES, LLC

What HARDESTY & HANOVER CONSTRUCTION SERVICES, LLC does

Hardesty & Hanover Construction Services, LLC (H&H) is a 139-year-old privately held infrastructure engineering firm headquartered in New York City, specializing in bridge and transportation infrastructure engineering. The firm was founded in 1887 and transitioned from partnership to LLC structure in 2013, with current leadership comprising CEO Sean Bluni and Co-Chief Operating Officers Laura Jones and Rich Stevens. H&H delivers professional engineering services — including planning, design, construction support, inspection, and program delivery — across bridges (movable bascule, swing, lift, and fixed-span), highways and interchanges, rail and transit, marine and port facilities, municipal infrastructure, and tunnels. Its technical differentiation centers on movable bridge engineering, demonstrated by flagship projects such as the Unionport Bascule Bridge in the Bronx ($250M, AISC Movable Span Award 2026), the 184m Renfrew Bridge in Scotland (NCE Road Bridge of the Year 2026), and the Portal North Bridge over the Hackensack River for Amtrak ($1.5B).

The firm serves exclusively government transportation clients — federal, state, county, and municipal — through professional services contracts procured via competitive bidding (RFQ/RFP) and design-build delivery. Marquee clients include NYSDOT ($1.7B Hunts Point program), FDOT (Moving I-4 Forward, Jupiter Federal Bridge), NJDOT, NJ TRANSIT, NYCDOT, Amtrak, NJTA, Florida's Turnpike Enterprise, and Multnomah County. The firm operates 33+ offices across the US plus a London office, with 300+ professionals in its New York headquarters alone and an ENR ranking of #9 in Top Bridge Engineering Firms, #42 in Top Transportation Firms, and #156 in Top 500 Design Firms (all 2026). Service delivery emphasizes alternative delivery methods (design-build), emergency response capabilities (e.g., Shark River Bridge), and multidisciplinary engineering including structural, civil, geotechnical, mechanical (Kinetic Systems), and electrical disciplines.

H&H monetizes through project-based professional services fees paid by government agencies, with pricing not publicly disclosed and revenue generated under multi-year contracts tied to infrastructure programs. The firm maintains active growth vectors in the Pacific Northwest (Portland office expansion with senior hire in July 2026), Florida (new Florida Leader in June 2026), and the UK (Renfrew and Herring Bridge awards). Recent strategic moves include the promotion of two Co-COOs in January 2026, addition of a Director of Program Delivery to formalize program management services, and ongoing Associate Group expansion. The firm is a professional services organization with no software, API, AI, or platform technology offerings in the data — its competitive position rests on talent specialization, 139-year brand, and qualification-based procurement advantages with DOTs.
