NEW YORK – On October 15, CTBUH New York City, in association with the New York Young Professionals Committee (YPC), hosted more than 115 professionals for a presentation of the architectural and engineering design of 432 Park Avenue, the tallest residential building in the Western Hemisphere. The event took place inside the 432 Park Sales Center at the General Motors Building, a space generously donated by Macklowe Properties, which included several scale models and life-size samples of key building components, including a 10-foot-by-10-foot (three-meter-by-three-meter) window.

|Prior to the presentation, Dennis Poon, CTBUH Trustee and Vice Chairman of Thornton Tomasetti, made opening remarks and introduced the evening’s speakers. Mr. Poon discussed the professional benefits of CTBUH membership and promoted the Annual Conference to be held in New York in late October. A welcome statement was then given by David Dods, Senior Project Executive for 432 Park Avenue and Senior Vice President of McGraw Hudson Construction Corp.|

Next, Jae In Choi, Project Manager of 432 Park Avenue from Rafael Viñoly Architects discussed the project’s design history and the unique zoning requirements of the site. Mr. Choi presented a selection of initial schemes, which investigated the basket-structure and stacked-mansion-in-the-sky concepts. He also discussed the development of the various double-height open cores, which emphasized the stacked design; allowed for mechanical equipment and fire protection tanks to be consolidated at key points throughout the building; and provided windbreaks and designated areas for the outrigger system required to achieve the building’s structural stability.
Subsequently, Silvian Marcus, Director of WSP Building Structures discussed the various considerations when designing super-slender towers. Mr. Marcus presented the design of the central core and perimeter frame, which resulted in a floor plate free of interior columns to maximize the sellable area and ultimately provided maximum flexibility for the subdivision of each floor. He then presented the strategies used to mitigate the effects of wind loads including the use of a double tuned mass damper to reduce undesirable accelerations in the building and increase occupant comfort.
Lastly, Gary Pomerantz, Executive Vice President of WSP Building Systems, presented the design of the mechanical, electrical, and fire protection systems. Mr. Pomerantz presented several design options for each system and discussed the logic behind the selection of the final design. He discussed the challenges of providing such systems in a luxury high-rise tower and explained the importance of designing phased building systems to support the construction process. Mr. Pomerantz concluded by discussing the various life safety requirements including smoke control, emergency power, wet fire protection, and emergency communication systems unique to supertall towers.

|Following the presentations, there was a Q&A session moderated by Elizabeth Geldres of Rafael Viñoly Architects and Christopher Shirley of WSP Building Structures, which discussed the design of the façade maintenance system and the utilization of structural GPS monitoring throughout the construction process. At the conclusion of the event a reception was held at Whiskey Trader.|
