Constructability of complex architectural shapes: a systematic literature review

Abstract The use of parametric computational models led to a revolution in building shapes. However, the formal freedom brought about by parametric models has also posed new challenges, especially concerning the construction process and the use of materials in architecture using complex shapes. Therefore, for the development of an efficient and effective architecture, it is essential to understand constructability or how manufacturing and assembly processes and materials influence the generation of shapes. Hence, this article aims to identify and analyse the state of the art regarding the manufacturing and assembly processes of complex architectural forms through a Systematic Literature Review (SLR). After searching five databases, 142 papers were found, of which 61 were selected for analysis. These works offered a broad view of the application of materials and digital manufacturing techniques in the construction of complex shapes, as well as different constructability criteria used for shape analysis, mentioned in 17 papers. This study’s conclusion is that the development of complex architectural forms requires the integration between the shape design, the construction materials that will be used, and the manufacturing and assembly processes.
