Abstract

Digital Fabrication (dfab) is emerging as a new technical and computational approach for the architecture and construction industry. However, managing dfab requires processes to account for integrated design and construction processes. Lean construction management and design for manufacture and assembly (DfMA) offer two potential strategies for managing dfab. Although dfab, DfMA and lean have each been of wide interest among scholars, little research has examined their potential synergies. This paper conducts a literature review of all papers based on the authors' knowledge that discuss at least two of the three topics, and identifies common practices shared between the lean, DfMA and dfab. Two practices – design-to-target value and concurrent engineering – are found to be shared by all the three topics. Further, seven practices shared by two of the three topics: pull-planning, design-to-cost, standardisation, Jidoka, Just-in-Time, design-to-construct and knowledge sharing. This paper demonstrates the opportunities for synergies between lean, DfMA and dfab, and concludes with suggestions for future research to further investigate implementation of lean management for dfab in construction.
