A transformer building was built on top of an existing concrete pad, and the facility’s key components were protected with a floodwall. Retrofit design added a second floor to the existing fan plant building and raised its louvers above flood elevation. The effort was completed with minimal disruption to subway operations while enhancing the quality of life for local neighborhood residents. Overcoming numerous site constraints and technical challenges, a design team led by Gannett Fleming delivered significant upgrades to FP 7204 that achieved all resiliency requirements. FP 7204 also serves as an emergency egress for the public, providing an escape route from the tunnels during an emergency event. In addition, in the event of a fire in the tunnels, the plants’ massive fans serve to draw smoke out, giving people time to escape. Innovative design solutions combined structural logic with contextual sensitivity, creating an aesthetically appealing structure integrated seamlessly into the surrounding community.įan plants are critical components of the New York City subway system, providing passive ventilation by enabling the piston action of moving trains to pull fresh air down into the tunnels below. A retrofit of Metropolitan Transportation Authority (MTA) New York City Transit (NYCT) Fan Plant (FP) 7204, extensively damaged by Hurricane Sandy, provided resiliency of essential infrastructure so it could withstand a future major storm.
