ETH Zurich, working in collaboration with Zaha Hadid Architects Computation and Design Group (ZHCODE) and Architecture Extrapolated (R-Ex) have unveiled a 3D-knitted shell serving as the primary shaping element for curved concrete structures. The “KnitCandela” prototype represents the first application of this technology at an architectural scale, a five-tonne concrete structure on display at the Museo Universitario Arte Contemporaneo in Mexico City. Forming part of ZHA’s first exhibition in Latin America, KnitCandela “pays homage to the Spanish-Mexican architect and engineer Felix Candela” by reimagining his inventive concrete shell structures through an innovative KnitCrete formwork technology. With a knitting time of 36 hours, the cable-net and fabric formwork system allows for expressive, freeform concrete surfaces to be constructed without the needs for molds.
