KnitCandela is a thin, sinuous concrete waffle shell. Built on an ultra-lightweight knitted formwork, which was brought from Switzerland to Mexico in two suitcases, KnitCandela demonstrates that employing a flexible cable-net formwork together with a knitted textile can cut down on material, labour, and construction waste, while simplifying and streamlining the construction process for sophisticated shapes in concrete. Realised with a state-of-the-art BIM approach using the computational framework COMPAS, the structural design, engineering, digital fabrication, and construction of KnitCandela were incredibly efficient.
