New York, USA
This interactive sculpture creates a new innovative centrepiece for the Hudson Yards redevelopment.
Designed as a lattice of ramps and landings, forming a rigid, monolithic structure, Vessel is characterised by inner and outer layers of stairs comprising almost 2,500 individual steps.
The structural engineering challenges that were met to deliver this piece of urban inhabitable sculpture ranged through analysis, design and construction.
But for each of these, the uniqueness of the structure meant the challenges themselves were also unique.
The structure is the architecture and vice versa and with the form comparable to a massive spring, addressing vibration was more complex than in other structures and was met with impressive engineering analysis and design.
