Structural Glass Challenges: Hudson Yards Observation Deck

Structural, architectural and installation demands must all be considered in glass structures. The best solutions do not form a compromise between these demands but integrate them into one solution. This paper presents a case study of three glass structures with varying challenges on the Observation Deck of Hudson Yards in New York – a 3m, cantilevered Windscreen subject to wind gusts of up to 4.7 kPa, an outdoor Glass Floor with high traffic, and a combination glass floor and window structure. In this paper, we look at the challenges of laminated connections, ensuring structural safety and performance, meeting a clear architectural vision, and installing glass to high tolerances with access from one side at 350m height.
