Hudson Yards is changing the look of New York – and will change how the world looks at New York. Unprecedented and ongoing investment marks Hudson Yards as the nation’s largest development, and one of the most complex construction projects in the history of New York City.


Constructed on 28- acres over a working rail yard, two “platforms” bridge over 30 active train tracks, three rail tunnels and the new Gateway Tunnel.

300 caissons support the platforms and buildings. The caissons (four to five feet in diameter and 20 to 80 feet in depth) are drilled deep into the bedrock between existing tracks. Finished towers extend from the caisson foundations, through the platforms, and then rise skyward.
This eastern portion of the platform will use 25,000 tons of steel, 14,000 cubic yards of concrete and weigh more than 35,000 tons.

Caisson drilling started in March 2014 and the platform was completed in 2015. Throughout construction the trains have remained operational, and the new No. 7 Subway Extension opened at Hudson Yards in 2015.

Reality Rising

The first complete tower on the site is 10 Hudson Yards and opened in May 2016. It is fully leased to companies that include Coach Inc., L’Oréal USA, SAP, Intersection, Sidewalk Labs, Vayner Media and Boston Consulting Group including BCG Digital. 10 Hudson Yards ascends 895 feet with 1.8 million square feet of commercial space.

Another prominent skyscraper under construction is 30 Hudson Yards, with 2.6 million square feet. At 1,296 feet high, it will be completed in 2019 as the second tallest office building in New York. 30 Hudson Yards will be home to leading media, business and financial companies including HBO, CNN, Turner Broadcasting, Time Warner, Inc., KKR & Co. and Wells Fargo Securities.

55 Hudson Yards is the third commercial tower. At 780 feet and 1.3 million square feet, it will be home to MarketAxess, Milbank and Boise, Schiller & Flexner, LLP. The office towers are part of the overall master plan that incudes 4,000 residences, a new hotel and a dynamic retail space that will feature more than 100 luxury and specialty shops, include Manhattan’s first ever Neiman Marcus store. The retail component will include an collection of restaurants, and overlook the enthralling Public Square and Gardens. These components will open to the public by 2018.



When you’re doing something for the first time, innovation comes with the territory. The advancements at Hudson Yards are revolutionary, and are infused into nearly every aspect of the project. A partial list of what’s to come:

  • Onsite power generation and monitoring
  • Continual monitoring of traffic patterns, air quality, power demand, temperature, pedestrian flow and environmental conditions with ongoing optimization for safety and comfort
  • Heat Control – The train yard can reach a scorching 150°F warming the soil. A sophisticated network of tubing will circulate cooling liquids to protect the plants’ roots.
  • Ventilation – To remove heat generated by trains, a ventilation system powered by 15 fans (commonly used in commercial jet engines) will supply fresh air at 45 MPH to the train tracks below.
  • Smart Soil – A “soil sandwich” of sand and gravel between two concrete slabs is being constructed to compensate for the shallow platform depth to protect plants’ roots and promote growth that is wide and shallow. This advanced layering includes provisions for soil aeration, irrigation, drainage, root development and ongoing control of nutrients.
  • Irrigation – Every drop of rainwater that falls on the Hudson Yards Public Square and Gardens will be collected into a 60,000-gallon tank and reused for irrigation. This will save 6.5-megawatt hours of energy and offset 5 tons of greenhouse gas every year.
