Procedural Landscapes 2, ETH Zurich, 2011
State of the art technology in the field of non-standard concrete formwork is largely based on subtractive and waste intensive fabrication methods. These methods prove very efficient for a large scale production of identical parts. An efficient and sustainable fabrication of individual parts demands for the development of new formwork strategies. This teaching project proposes the use of granular materials such as sand as a reusable molding material to fabricate unique building elements in concrete with a minimum of waste resulting from the formwork. The analysis of the self-organizational properties of the material and the subsequent extraction of design parameters allows to precisely control the material aggregations and exploit this process for digital design and fabrication.
In a 4 week workshop, the students were challenged to design a concrete retaining wall along the Rhein river in Basel. To verify and test the concepts, 3 individual prototypes of a size of 1m x 2m were fabricated on the professorships robotic fabrication unit. The project was conducted in collaboration with Prof. Christophe Girot (ILA) and Yael Girot (Atelier Girot).
