Sedimentation _sand additive graded manufacturing. ( Rizal Ambotang, Adam Roggero, Wenjie Cao )

Abstract
This project is a proof-of-concept on the development of a non-permanent architecture in a shifting landscape of a desert. The project uses Pushkar camel festival as the contextual basis of the desert biotope. The changing role of the festival from a long-standing camel trading event to a tourist oriented festival highlights the impact of modernity on ritual tradition. This provide an opportunity to move the festival to a location that is true to the spirit of the traditional culture of the camel and Rajasthani herders. The project attempt to use this opportunity to explore and propose a shifting architecture that is sustainable and performative to the desert biotope. Using sand as the primary building material, the project proposes the use of natural and man-made processes as a unique construction method for the shifting architecture. The project engaged a series of studies and analysis to establish the framework of the project. A ritual study establishes the core tradition of the festival as well as the relationship between human and camel. The analysis of the desert biotope provides the contextual details of the project which includes the dunes formation, the Aeolian environment and the associated natural processes that involved in the development of the desert landform. Concurrently, the material study explores the material potential of sand as well as finding a suitable construction technique in the desert environment. From the material analysis, the project developed construction application for solidification of sand. A sustainable construction approach uses microbial induced cementation of loose sand as the method of solidification. The augmentation of the bacteria onto the target surface is done through the method of spraying to maintain consistent thickness in layering.  

The analysis of the journey in the changing landscape resulted in the pattern of movement of herders and their camels between the villages. A path-finding algorithm proposed possible locations for construction. The project then developed a form generation algorithm (the Game of Life) using the concept of cellular automaton to simulate growth. The form building technique combines a more traditional dune fencing method to provide overall control of the form as well as the initial ground alphamap to provide initial design of the structure. The form generation algorithm also simulates the erosion process of Aeolian abrasion and deflation to sculpt the spaces over time. This natural process also highlights the non-permanence nature of the construction and deconstruction. The shifting nature of the structure is attributed by the combination of sand deposition and the fencing approach. The optimization of the algorithm allows for fine tuning the form to produce ritual specific spatial qualities as well as trading and habitation spaces. The project highlight the viability of the combined natural process with human interventions to produce a shifting architecture in the desert environment. The project also claimed the applicability of a large-scale augmentation of bacteria induced cementation using the spraying technique to build sand-based structure. Further research opportunity in the use of spraying technique and sedimentation-inspired technique of layered solidification can produce practical application for sand based structure that is sustainable and performative to its environment.
