432 Park Avenue Tuned Mass Dampers

432 Park Avenue, New York City, USA

Overlooking Central Park in Manhattan, 432 Park Avenue boasts 104 condominium apartments for wealthy New Yorkers. Its condos offer high ceilings and range from a modest 351 square foot studio to an expansive $95 million penthouse which includes a library, six bedrooms, and seven bathrooms. 

Calling 432 Park Avenue a luxury residence would be putting it mildly. Residents of the building have access to a number of amenities including private charters, housekeeping, personal shopping, pet walking and grooming and art restoration. The building’s private restaurant is overseen by a michelin-starred chef. The structure is truly a symbol of opulence in the heart of Manhattan.

Structurally, the massive skyscraper is impressive. It is composed of 30 inch thick walls and a 30 foot core of reinforced concrete. The outer structure is comprised of a grid of columns of reinforced concrete. Such a layout means that the apartments within the building may maintain a fully open concept layout.

Tuned Mass Damper for Apartment Building

To achieve such a height, it was also necessary to include Tuned Mass Dampers (TMDs) as part of the design.

Two TMDs, with a combined weight of 1370 tonnes, were installed at 432 Park Ave., a super tall residential project in midtown Manhattan. Upon its completion, 432 Park Ave. was the third tallest building in the United States and the tallest residential tower in the western hemisphere, at 1,396 feet tall.

A&H Custom Machine created detailed drawings for the project, and welded, machined and assembled the TMDs in their shop to ensure perfect fit and form. The TMDs were then disassembled and shipped by A&H Custom Machine to a holding yard in New York. From there, the TMDs were marshalled out to the site for installation.

The team at A&H Custom Machine takes great pride in the role that it played in the design and construction of 432 Park Avenue.
