SKYSCRAPER SEMINAR: 125 Greenwich Street

24 April 6:30pm - 8:00pm
Organized by: Skyscraper Museum
Venue: The Skyscraper Museum, The Skyscraper Museum
39 Battery Place
New York

The one constant in the evolution of the design of the 912-foot tall, super-slender condominium at 125 Greenwich Street, just south of the World Trade Center site in lower Manhattan, is its postage-stamp site, barely 83' x 119 ft. After several early schemes, which ranged in height from 1,100 to nearly 1,400 ft., the tower now under construction will top out at 912 ft./ 278 meters. Offering insights into their strategies of design and structural engineering of the skyscraper are Jae In Choi, the project architect from Rafael Vinoly Architects, and structural engineer Stephen DeSimone of DeSimone Consulting Engineers. In the changing market for luxury units and the evolving Downtown demographics, the developer’s continuing analysis led to a rethinking of the mix of apartments and placement of amenity floors and, thus, a revised structural approach and expression in the tower’s form. Choi and DeSimone will detail how the current design answers the challenges of mixed floor plans, maximized views, and wind engineering, among other issues. 125 Greenwich Street is being developed by Bizzi & Partners, a global real estate firm with offices in Milan, New York, San Paolo and Tallinn. In addition to Rafael Vinoly Architects and DeSimone Consulting Engineers, consultants to the project include Reginald D. Hough Associates, Cosentini Associates, and Robert Schwartz & Associates. Join the speakers for another program in the Museum's continuing series of Skyscraper Seminars, exploring subjects of theory and practice for design professionals.
