Hudson Yards Redevelopment

OVERVIEW

Hudson Yards encompasses 28 acres atop a working railyard on the West Side of Manhattan. Located between 10^th and 12^th Avenues from West 30^th to West 34^th Street, Hudson Yards is the largest private development in the United States and one of the most complex construction projects in New York’s history. The development includes more than 18 million SF of commercial and residential space, 14 acres of public space, cultural venues, and the world’s first Equinox Hotel.

With extensive knowledge of the overall West Side redevelopment plan, MTA No. 7 subway line design, and Eleventh Avenue Viaduct reconstruction, Langan played an integral role in many aspects of the Hudson Yards project. We worked closely with agencies including the MTA, Hudson Yards Development Corporation, NYCEDC, NYCDOT, NYCDEP, and Amtrak, conducted a site-specific seismic study, and performed a 3D Finite Element Analysis to evaluate the potential influence of drilled-shaft foundation loads on the No. 7 subway extension. Our work successfully passed the peer review process by MTA Capital Construction.

FOUNDATIONS FOR THE EAST YARD PLATFORM

The development of Hudson Yards transformed the West Side and New York City’s iconic skyline. For the massive development to succeed, two “platforms” had to be developed to bridge over 30 active train tracks and three rail tunnels.

The east platform is supported by 380 high-capacity caissons that transfer loads from the platform and buildings into the underlying bedrock. As the geotechnical and environmental engineer for the platform, Langan kept the project moving forward despite challenges. Our unconventional approach to caisson load tests, advanced geotechnical studies and field testing, and integration of geotechnical and environmental field work translated into significant foundation construction time and materials savings.
