Hudson Yards and #7 Subway Extension
A once-in a-lifetime infrastructure project, SBI’s Technical and Advisory solutions helped to revitalize Hudson Yards and transform the urban landscape of New York City.
In 2005, the City of New York established the Hudson Yards Development Corporation (HYDC) to transform the Hudson Yards area into a vibrant, pedestrian-friendly, transit-oriented mixed-use district. This comprehensive initiative involved extending the No. 7 Subway line from its terminal at the 42nd Street-Times Square Station to the new 34th Street-Hudson Yards Station at 34th Street and Eleventh Avenue. The new station links to 18 subway lines, thereby connecting the rest of the city to Hudson Yards and increasing accessibility of the mixed-use community to residents, commuters and visitors.
To achieve its mission, HYDC engaged SBI Consultants to provide cost engineering and risk assessment services that included the evaluation of budgets and constructability of tunneling and ventilation work, understanding the impact of the No. 7 Subway infrastructure on adjacent properties, cost estimates for multiple Hudson Yard sites including the Culture Shed, and mitigating the overall project risk.
SBI met the numerous complexities of this project with forethought, flexibility, creativity and close attention to detail. SBI analysts constructed detailed cost models, assessed foundation easements, and created best end-use scenarios that were invaluable in consolidating effective building strategies. The project required cost estimate data verification prepared by third parties, constructability studies and detailed construction and cost of assessment resulting from the infrastructure impacts.
Completed in 2016, SBI was proud to play a key role in this once-in-a-lifetime infrastructure challenge that revitalized the Midtown West area of Manhattan. Throughout every phase, SBI’s talented engineers actively collaborated with HYDC members and a range of tunneling and other engineering experts to drive results and ensure its success.
