Abstract

Abstract Construction waste is a global concern among the practitioners and has got attention of the researchers for many years. This issue is serious in construction industry of Pakistan also and various researchers have contributed in addressing it. This paper identified design and procurement related factors and assessed their risk level in causing construction waste. Data was collected through questionnaire survey amongst the practitioners from client consultants and contractors working on construction projects in Karachi and Hyderabad division of the Sind province. A total of 72 completed questionnaire forms were analysed and the results shows that 8 of the 20 factors are highly important factors and fall in the red zone of the risk matrix. It was also observed that last minute client requirements is reported as most important factor in design related issues while “items not in compliance with specification” is the most risk factor in the category of the procurement. Besides these, “last minute client requirements” and “Mistakes in quantity surveys” are the key factors which have significant effect on project cost. The findings of this study will be helpful for the practitioner to improve design and procurement quality for controlling the waste generation.

引致建筑废物产生的设计及采购因素的风险水平

摘要建筑垃圾是一个全球性的问题，多年来一直受到研究者的关注。这一问题在巴基斯坦建筑业也很严重，各研究人员为解决这一问题做出了贡献。本文确定了设计和采购相关因素，并评估了它们造成建筑垃圾的风险水平。数据是通过对信德省卡拉奇和海得拉巴地区从事建筑项目的客户顾问和承包商的从业人员进行问卷调查收集的。共分析了72份完整的问卷，结果显示，20个因素中有8个是高度重要的因素，属于风险矩阵的红色区域。另据观察，最后一分钟的客户要求被报告为设计相关问题中最重要的因素，而“不符合规范的物品”是采购类别中最危险的因素。除此之外，“最后一分钟的客户要求”和“数量调查中的错误”是影响项目成本的关键因素。这项研究的结果将有助于从业者提高控制废物产生的设计和采购质量。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
