Extreme wind loads on one of the USA’s tallest residential buildings, enormous natural stone plates, a new American testing procedure for the products used, as well as a complicated installation process: due to these high require-ments, the project’s client, China Overseas America, Inc., opted for the fischer FZP II in order to attach the 25,000-square metre facade. Conventional fixing methods weren’t able to meet the high demands of the heavy load. The FZP II was chosen in a variant with a 13-millimetre drill hole diameter, an expanded anchor length of 30 millimetres, a connecting thread with a diameter of eight millimetres, and a free thread length of 13 millimetres. 90,000 of these fischer undercut anchors securely fix the heavy natural stone plates to 99 Hudson Street.

In order to invisibly attach the facade elements, they were equipped with undercut drill holes in the Bavarian factory of the natural stone supplier JMS. They form an interlocking fixing completely free from expansion pressure in connection with the fischer Zykon panel anchor FZP II, which allows a lot of architectural room to manoeuvre. The entire facade modules were subsequently joined together along with the anchors and natural stone by the facade construction company Gamma in Miami, before being delivered to the building site in Jersey City.

“We can guarantee the client that their high levels of requirement in terms of quality and short construction times will be met. We achieve this through prefabrication in the factory and by working together with the manufacturer of the facade material, as well as the facade construction firm. This helps the client to adhere to their construction timeline and budget”, explains Christian Knoll, Managing Director fischer SystemTec.

99 Hudson Street will provide 781 residential units across 79 floors from the end of 2018. Its location by the Hudson River allows direct views to the One World Trade Center in New York City. As well as 137,000 square metres of residential area, New Jersey’s highest building also provides 1,400 square metres of retail space as well as a public area of 1,300 square metres. The project has been planned by the Perkins Eastman architecture firm.
