Modular Robotic Prefabrication of Discrete Aggregations Driven by BIM and Computational Design

Discrete architecture is recognized as a computational design approach which uses computation to generate algorithmically combinable aggregations. It is therefore a promising innovation for increasing design process productivity through the adaptability of the aggregations it generates. In the built environment, discrete design is usually identified with the modular method. It is a construction process based on the aggregation of different modules assembled according to well-defined connections to ensure the building's integrity and functionality. It involves off-site manufacturing, and hence a controlled environment ensuring more predictability over weathering and change. But like in conventional construction practices, the fragmentation of modular construction processes hinders its productivity. As a result, this construction approach requires adequate technologies and communication tools to improve collaboration and productivity. This paper aims to address these requirements by adopting a BIM-driven computational approach to design processes and a robotic approach to prefabrication processes. It proposes a modular construction framework for design and production, and presents the results through a study adopting BIM-driven discrete design and robotic manufacturing. (C) 2022 The Authors.
