Using the dfma approach in the early integration of actors for the design of an industrialized timber building - case study

Abstract

Design for Manufacture and Assembly (DfMA) isamethodology that optimizes the design process to facilitate manufacturing and assembly, promoting more efficient and cost-effective construction. This study describes the process of early integration of actors inacase study of an industrialized timber building in Chile, framed in the Housing Emergency Plan. Involving architects, engineers, manufacturers, and builders from the early stages, the DfMA methodology was applied to improve communication and coordination between all actors. Five design stages were identified based on the RIBA guide, and BIM and modeling tools were used to integrate information from all participants. The results indicate that, although design time increases, production is more efficient, with fewer errors and rework, and higher construction quality. This study providesaframework for future projects in the construction industry, highlighting the importance of early integration and use of digital tools. Future work should validate time and cost savings, reduction in waste, improvement in quality and processes in manufacturing and construction phases. © (2025) WORLD CONFERENCE ON TIMBER ENGINEERING 2025 (WCTE 2025) All rights reserved.
