About the company

H&H plans, designs and inspects bridges, highways, rail and transit lines, tunnels and ports for infrastructure owners. Its specialty is movable bridges that open to let ships pass, with structural engineers working alongside mechanical and electrical specialists. Owners pay for engineering consulting that takes projects from early studies through detailed design and construction support. Teams assess existing structures, test their components and plan repairs, while civil and geotechnical specialists address roads, drainage and foundations. H&H was founded in Kansas City, Missouri, in 1887 and is headquartered in New York City, where it has been based since 1920.

Simplify's Take

What believers are saying

  • H&H funds licensing-exam study time and runs certified monthly engineering webinars plus annual full-day seminars.
  • H&H's movable-machinery design contributed to Renfrew's Road Bridge Project of the Year award in July 2026.
  • New York selected H&H's team for a three-region stormwater-design agreement in April 2026, ahead of Gannett Fleming.

What critics are saying

  • H&H's New York inspection leaders face fieldwork at heights, in confined spaces, around traffic and in variable weather.
  • Denver's December 2025 on-call agreement issues H&H task orders only after establishing project needs and available funding.
  • H&H finished second for New York's statewide utility-engineering agreement in May 2026, behind Infra-Model Engineering.

What makes H&H unique

  • H&H applies industrial crane technology to moving architecture, engineering the expandable shell of New York's Shed arts venue.
  • H&H extends its building-design reach through structural specialist Thornton Tomasetti, covering supporting frames, tall buildings and facades.
  • H&H's inspection practice has examined over 4,000 structures for more than 30 owners, combining structural, mechanical and electrical assessments.
