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.
本文旨在确定通过拆解设计(DfD)实现有效材料回收所需的关键成功因素(CSF)。本文采用的研究方法基于一种顺序探索性混合方法策略。在对文献进行全面回顾并开展了四次焦点小组讨论(FGD)之后,确定了43个拆解设计因素,并将其纳入问卷调查。数据分析包括克朗巴哈α信度分析、使用显著性指数的均值检验以及探索性因素分析。因素分析结果表明,存在一个由五个拆解设计因素组构成的潜在因素结构,这些因素组包括“严格的法规和政策”“拆解设计过程与能力”“材料回收设计”“材料再利用设计”以及“建筑灵活性设计”。这些拆解设计因素组表明,拆解设计的要求不仅限于技术能力,诸如严格的法规政策以及拆解的设计过程与能力等非技术因素在设计可拆解建筑方面也至关重要。关注所有这些类别中确定的因素将有助于解决可能阻碍拆解设计有效性的障碍。本研究结果将有助于设计和项目经理了解在采用拆解设计作为从垃圾填埋场转移废物的策略时可能需要改进的方面。
