The evolution of architectural computing: from Building Modelling to Design Computation

Extract

In recent decades, the interrelations between architecture and computation have fostered new design concepts and design methods, which challenge existing design and building processes. Specifically, the increased use of parametric methods and scripting allow for the development of modelling and fabrication techniques, which in turn challenge the role of drawing as one of the main tools for conceptualising and realising architecture. In 1975 Chuck Eastman proposed the conceptual basis for a more complete and effective role for the use of the computer in architecture with his ‘Building Description System’. During the 1980s, software developer Robert Aish contributed to the development of RUCAPS – one of the earliest applications based on the concept of ‘building modelling’. Later developments of building modelling envisaged further modes of collaboration between architecture, engineering, and construction in the (AEC) industry.
