Abstract

Computational design and digital fabrication facilitate the construction of compression-dominant structures, such as the Striatus pedestrian bridge, built in Venice, Italy, in 2021. This paper addresses the construction process for Phoenix, a permanent 3D-concrete-printed (3DCP), unreinforced-masonry (URM) arched bridge completed in Lyon, France, in 2023. The implemented CAD workflow extends to full CAM specifications for the CLT falsework. It delivers a modular, dry-assembled solution for preassembled groups of blocks to be lifted into place by a construction crane. Our findings indicate increased construction process efficiency, improved control of the bespoke waffle geometry, integration of standard metal scaffolding and falsework parts, higher tolerance control, and effective global referencing. Furthermore, we incorporate adjustable gaps; thus, grouting compensates for assembly imprecisions at the supports. Crucially, falsework CLT volume utilised per square meter of bridge deck was reduced by 62% compared to Striatus, reducing single-used material and resulting construction waste.
