Seismic Experts At Your Call.
Hardesty & Hanover routinely provides seismic analysis and design in accordance with AASHTO guidelines. We also help clients with two and three-level seismic analyses required by New York City DOT and AREMA. Site-specific geotechnical investigation and soil-foundation-structure interaction are considered where appropriate, often utilizing our geotechnical expertise with non-linear analysis programs.
Our experience in seismic evaluation includes one of the first major bridges in Northeast America to be investigated for seismic loading - the Tappan Zee Bridge on the New York State Thruway. Hardesty & Hanover has also analyzed existing structures for seismic loading and developed appropriate retrofit measures.
We’ve seen and done it all. We’ve even helped pioneer it.
