Hudson Yards Redevelopment

OVERVIEW

This major New York City rezoning and redevelopment, under the joint guidance of The City of New York, the Metropolitan Transportation Authority (MTA), Hudson Yards Development Corporation (HYDC) and State of New York initiatives, is in the process of reinventing the Hudson Yards area in Midtown Manhattan. Once complete, the site will include more than 17,000,000 SF of commercial and residential developments and 14 acres of open park space, as well as a cultural venue, 750-person public school and 200-room luxury hotel.

Langan’s extensive knowledge and understanding of the overall West Side redevelopment plans, MTA No. 7 subway line design, and Eleventh Avenue Viaduct reconstruction has been critical to private development and agencies alike. Interaction and close coordination with agencies such as the MTA, HYDC, New York City Economic Development Corporation (NYCEDC), New York City Department of Transportation (NYCDOT), New York City Department of Environmental Protection (NYCDEP), and Amtrak have been paramount to success of each project.

FOUNDATIONS FOR EAST YARD PLATFORM COMPLETE

Hudson Yards creates real estate out of thin air – literally. Two “platforms” will bridge over 30 active train tracks and will support towers, mid-rises, and public open space. Langan was the geotechnical and environmental engineer for the east platform, which is supported by 380 high-capacity caissons that transfer loads from the platform and buildings into the underlying bedrock.

Langan played a key role in helping to move east platform construction forward. Our unconventional approach to caisson load tests and integration of geotechnical and environmental field work translated into signification foundation construction time and materials savings. The completion of the east platform is a milestone for the project and sets the stage for vertical development, which will ultimately help to reinvigorate Manhattan’s Far West Side.
