Zaha Hadid Architects has released details of a second collaborative effort with Holcim on a 3D printed bridge concept that was first debuted as part of the 2021 Venice Architecture Biennale. The new ten-ton Phoenix design offers an evolution of the innovations seen in the previous Striatus.
The category has been introduced this year to reward an innovation that has transformed an aspect of a practice’s work. This can be either a technological
Striatus, the world’s first 3D concrete printed bridge, was recently opened to the public as part of the Venice Architecture Biennale. Designed by Block Research Group and Zaha Hadid Architects, this construction innovation was achieved in collaboration with incremental3D and Holcim.
Striatus establishes a new language for concrete that is digital, environmentally advanced and circular by design. The footbridge holds together through compression with no reinforcements, applying computational design and 3D printing for minimal material use and maximum strength.
Philippe Block, co-director of the Block Research Group at ETH Zurich: “The name ‘Striatus’ reflects the bridge’s structural logic and fabrication process. In arched and vaulted structures, material is placed such that forces can travel to the supports in pure compression. Strength is created through geometry, using a fraction of the materials used in conventional concrete beams.”
