Rapid Clay Formations, 2019-2020
Project for the UIA 2020 Pavilion, Rio de Janeiro
Rapid Clay Formations originated from the second trimester of the MAS ETH DFAB. The project was developed for the World Congress of Architects UIA 2020 in Rio de Janeiro in form of an undulating wall of twenty meters made entirely from local clay and built by a mobile robot in the garden of Casa Firjan.
For the UIA 2020 clay wall at Casa Firjan in Rio de Janeiro, the aim was to demonstrate how the use of resourceful, energy-efficient and locally abundant materials such as clay can be combined with advanced digital building technologies for a construction method of temporary structures in which the material can be fully reused. A material mix based on locally sourced clay was developed and tested with the goal of minimising shrinkage whilst maintaining enough plasticity to ensure the boding of individual “soft bricks”. These “soft bricks” were developed to be placed by a transportable mobile robotic arm and platform, the In- situ Fabricator, enabling the accurate translation of a digital model into a real world construction.
The project is a precursor to the Clay Rotunda in Berne.
