Bronx, NY · Bridges · Client: MTA Bridges and Tunnels
Involvement in monitoring and investigating cable conditions to assess remaining strength, unwrapping main cables, and removing suspenders. Work included special tower inspections, design of structural steel repairs, and engineering of a custom jacking apparatus and temporary shoring system.
New York, NY · Bridges · Client: MTA Bridges and Tunnels
Participated in the seismic evaluation of the Ward and Randall's Island Viaducts. Work involved building complex multi-degree-of-freedom 3D finite element bridge models, evaluating dynamic responses, performing spectrum analysis, and designing seismic retrofits.
Fort Lee, NJ · Bridges · Client: The Port Authority of NY and NJ
Design and construction support services for replacing the helix ramp from the Palisades Interstate Parkway to the bridge. The scope included performing load rating analysis of the existing three bridges and developing conceptual demolition and erection procedures.
New York, NY · Bridges · Client: MTA Bridges and Tunnels
Replacement of the existing bridge deck with a concrete-filled steel grid deck, structural repairs, installation of underdeck inspection platforms, and seismic isolation bearings. Construction support included shop drawing review, load rating for construction loads, and design of temporary structures.
