Abstract

The aim of this paper is to identify Critical Success Factors (CSF) needed for effective material recovery through Design for Deconstruction (DfD). The research approach employed in this paper is based on a sequential exploratory mixed method strategy. After a thorough review of literature and conducting four Focus Group Discussion (FGDs), 43 DfD factors were identified and put together in a questionnaire survey. Data analyses include Cronbach’s alpha reliability analysis, mean testing using significance index,
and exploratory factor analysis. The result of the factor analysis reveals that an underlying factor structure of five DfD factors groups that include ‘stringent legislation and policy’, ‘deconstruction design process and competencies’, ‘design for material recovery’, ‘design for material reuse’, and ‘design for building flexibility’. These groups of DfD factor groups show that the requirements for DfD goes beyond technical competencies and that non-technical factors such as stringent legislation and policy and design process
and competency for deconstruction are key in designing deconstructable buildings. Paying attention to the factors identified in all of these categories will help to tackle impediments that could hinder the effectiveness of DfD. The results of this study would help design and project managers to understand areas of possible improvement in employing DfD as a strategy for diverting waste from landfills.
