South Ferry Subway Station
Building Overview
The South Ferry Station, located at the southern tip of Manhattan, has a long and complex structural history tied to the evolution of New York City’s subway system. The original station opened in 1905 as part of the city’s first IRT subway line. In 2009, a new modern South Ferry Station was constructed to replace the original loop configuration, featuring a full-length island platform, expanded circulation areas, and full ADA accessibility. In October 2012, Hurricane Sandy caused catastrophic flooding that inundated the station box, tunnels, and critical systems, rendering the facility inoperable. The post-Sandy rehabilitation focused on restoring the station and hardening it against future Category II storm events, including replacement of damaged architectural, electrical, mechanical, and structural components, installation of flood-resilient systems, new flood barriers and watertight doors, and upgrades to drainage and pumping capacity, ultimately restoring full service while significantly improving long-term resilience and public safety.
Project Scope
EOC provided structural engineering services for the design, analysis, and detailing of the structural steel sub-framing and attachment systems supporting the interior cladding panels. The scope included evaluation of gravity,wind and serviceability loads, development of load paths to the primary structure, coordination with architectural layouts and finish requirements, preparation of construction drawing, and on-site field inspections to verify that the installed sub-framing and attachment systems were constructed in compliance with the approved construction documents and engineering design intent, ensuring structural adequacy, constructability, and code compliance.
