Arup served as structural engineer for The Rising, a 9/11 memorial in Westchester County, which lies immediately north of New York City.
Architect Fred Schwartz’s concept for the memorial was selected by victims’ family members through a design competition.
Standing 83ft tall, the memorial consists of 109 2in diameter stainless steel pipes arranged in a circle. The pipes curve inward from a granite base to form a single spire.
Each pipe represents a Westchester resident lost in the attack on the World Trade Center. Victims’ names are engraved along the perimeter of the circular base.
Engineering design
Connecting the pipes to achieve visual continuity as they weave inward to become a single unit was key. We explored a number of options, including welding the pipes together, which proved prohibitively expensive.
The final design used a series of steel castings to form the intersections. Straight pipe segments were then welded to the nodes to complete the structure.
