Barriers and Strategies in Implementing Design for Disassembly and Adaptability Principles in Singapore: A Pathway to Circular Economy in the Construction Industry.

As sustainability becomes crucial in the global construction industry, Design for Disassembly and Adaptability (DfDA) principles are key to advancing a circular economy by reducing waste, conserving resources, and enhancing building adaptability. In Singapore, with its high‐density urban landscape and limited natural resources, the adoption of DfDA principles is especially vital to ensure long‐term environmental and economic resilience. This study investigated barriers to DfDA implementation in Singapore's construction industry, analyzed strategies to address these challenges, and examined differences in perceptions based on professional roles and experience through a literature review, a questionnaire survey, and interviews. Eleven barriers and eight strategies were identified. The top barriers included the lack of practical tools and guidelines, cost and schedule constraints, and negative public perception of reused building components. The most effective strategies included providing financial incentives and awards, developing explicit guidelines and frameworks, and promoting collaborative project delivery methods. Significant differences were observed in perceptions based on respondents' roles and experience. This study advances theoretical understanding by developing a novel systematic framework that integrates barriers and strategies for DfDA implementation and stakeholder dynamics in the construction industry. The findings provide practical guidance for developing targeted measures to promote sustainable building practices. These insights significantly contribute to advancing industry‐wide sustainability initiatives and global sustainable development goals. [ABSTRACT FROM AUTHOR]
