Beyond geometric complexity: a critical review of complexity theory and how it relates to architecture engineering and construction

The wide application of digital design, the advances of digital fabrication and robotic processes have facilitated the materialization of bespoke geometries. In turn it has raised the issue of how architects can reduce design complexity using computational techniques. This paper presents a survey on complexity theory inclusive of work from the disciplines which range from cybernetics to systems and information theory. We synthesize a taxonomy of different definitions of complexity and ways of managing design complexity by decomposing its different levels as they relate to the fields of architecture, engineering and construction. Our hypothesis is that by reviewing the literature on complexity theory which appears to be highly fragmented, we can aid designers build a better understanding of the underlying principles. Thus designers can develop a more system approach towards the use of digital design tools and make use of concepts coming from the field of complexity theory such as abstraction, adaptation and self-organization in order to come up with novel computational design methods. Such methods can enable designers to deal with design problems holistically and manage design complexity in the contemporary digital design context.
