Located in the South Street Seaport area of Manhattan, Pier 17 is a 300,000 SF mixed-use building with a green roof that hosts community events including fitness classes, movie screenings, and summer concerts. The pier was completely rebuilt after being damaged by Superstorm Sandy, with the addition of a contemporary building atop. Executed with marine-grade materials, the building features a resilient four-story façade and commanding views of the Brooklyn Bridge. Langan prepared a feasibility study to document utility services, determined site stormwater management issues, and progressed plans for utility relocations, roadway improvements, and sidewalk improvements. We also conducted field investigations and seismic analysis, provided survey services using ground mapping techniques, and assessed the condition of the pier with a marine structures study.
