In anticipation of the 2021 Olympic Games, France’s Plaine Commune Grand Paris has awarded a consortium the design-build contract for a 40-meter pedestrian footbridge made from 3D printed structural concrete. The consortium consists of civil engineering firm Freyssinet, Levigne and Cheron Architects, computing and artificial intelligence firm Quadric, building materials specialists LafrageHolcim and large-scale 3D printing firm XtreeE.
This project combines complementary technical expertise. It paves the way for the realization of complex architectural and structural 3D-printed concrete elements and for the development of customized solutions, with controlled costs and deadlines. According to XtreeE, the project is a world-first; bringing together 3D structural concrete printing and industry 4.0 to form a new ‘infrastructure typology’.
This project will validate the firm’s 3D printing technology, making it easier for similar projects to be deployed throughout France and around the world…and fully validates the 3D-printing technology established by XtreeE. Spanning 40 meters, the deck of the pedestrian bridge will be entirely constructed from 3D printed concrete. The consortium aims to use 60% less concrete material in the building of the bridge compared to conventional structures.
