Zaha Hadid Architects designed a sinuous concrete shell for its first exhibition in Mexico

Zaha Hadid Architects has designed an experimental structure that pays homage to the Spanish-Mexican architect and engineer Félix Candela. 

Made up of a thin, sinuous concrete shell built on ultra-lightweight knitted formwork, it was constructed at the Museo Universitario Arte Contemporáneo (MUAC) in Mexico City as part of Zaha Hadid Architects’ first exhibition in Latin America.

Inspired by the fluid forms of the colourful traditional dress of Jalisco, Mexico, the installation - called KnitCandela - reimagines his inventive concrete shell structures through the introduction of new computational design methods and innovative KnitCrete formwork technology.

KnitCandela features a dynamic geometry with internal colorful stripes surrounding the structure. While the structure’s local builders nicknamed the project 'sarape' (a striped scarf that originated in Mexico), KnitCandela’s form references his acclaimed restaurant at Xochimilco; a concept he further developed in several of his subsequent projects.

While Candela relied on combining hyperbolic paraboloid surfaces (“hypars”) to produce reusable formworks leading to a reduction of  construction waste, KnitCrete allows for the realisation of a much wider range of anticlastic geometries. 

With this cable-net and fabric formwork system, expressive, freeform concrete surfaces can now be constructed efficiently, without the need for complex moulds.

KnitCandela’s thin, double-curved concrete shell with a surface area of almost 50 sq.m. and weighing more than 5 tonnes, was applied on a KnitCrete formwork of only 55 kg. The knitted fabric of the formwork system was carried to Mexico from Switzerland in a suitcase.
