The Rushmore Building – Riverside Boulevard NYC

The Rushmore Building in Manhattan is a 130-metre high building with 41 floors close to Times Square in New York. With this project, the challenge lay in constructing the two-towered building complex above the rail tunnel used by New York's AMTRAK line.

For this reason, there were no construction activities on the riverside until recently. Two train lines transport daily traffic there, carrying an axle load of 25 metric tons, while a subway line is being planned on this stretch of track.

Compliance with the required ceiling height with smaller distance between floors

The Getzner solution

When it comes to bedding skyscrapers, Getzner Werkstoffe is winning over customers with a completely new approach: individual floors of the 41-storey building have elastic bearings. Two floors are completely decoupled from vibrations – like drawers that can be removed.

Neither of the two levels is connected to the building in a fixed manner. Moreover, at the sides of the building, Sylomer® mats protect the weight-bearing pillars against the effects of the wind.

Working together with architects and dynamics experts, Getzner drew up detailed load distribution plans where the load on each of the 350 attachment points was determined precisely.
