Abstract

The factor influencing waste generation in the Indian construction industry has been examined in previous studies, along with the most significant factors generating waste. However, no study has answered the question: do different stakeholders have similar concerns? This study aimed to identify the significant factors generating waste from the multi-stakeholder's perspectives. The factors generating construction waste were identified through a comprehensive literature analysis. A total of 36 construction waste-generating factors were identified and clustered into six different groups: design and drawing (DED), procurement and handling (PHL), construction methods and planning (CMP), human resources (HR), site condition (SC), and external (EX). A questionnaire survey was conducted to gather multi-stakeholder's viewpoints (designers, owners, and contractors) and was ranked based on the relative importance index (RII). The most significant factors indicated by all the groups were frequent design change, poor attitude and behavior of workers, ineffective planning and scheduling, and poor control and supervision. The findings could assist in facilitating waste management strategies to be more effective and focused. Overall, the study findings are expected to identify new patterns of cooperation among different stakeholders.

影响建筑垃圾产生的因素:来自印度的观点

在以前的研究中，已经审查了影响印度建筑业废物产生的因素，以及产生废物的最重要因素。然而，没有一项研究回答了这个问题:不同的利益相关者是否有相似的担忧?本研究旨在从多利益相关者的角度找出产生浪费的重要因素。通过综合文献分析，确定建筑垃圾产生的因素。共确定了36个产生建筑垃圾的因素，并将其分为六个不同的组:设计和图纸(DED)、采购和处理(PHL)、施工方法和规划(CMP)、人力资源(HR)、现场条件(SC)和外部(EX)。进行问卷调查，收集多方利益相关者(设计师、业主和承包商)的观点，并根据相对重要性指数(RII)进行排名。所有群体认为最重要的因素是频繁的设计变更，工人的不良态度和行为，无效的计划和调度，以及不良的控制和监督。研究结果有助于促进废物管理战略更加有效和集中。总体而言，研究结果有望确定不同利益相关者之间合作的新模式。

期刊介绍： Waste and Resource Management publishes original research and practice papers on all civil engineering and construction related aspects of the resource management cycle, from the minimization of waste, through the re-use and recycling, to the management and disposal of residual wastes. Associated legislation, standards, socio-economic considerations and links with sustainable consumption and production are included. The range of subjects covered encompasses, but is not restricted to, strategies for reducing construction waste through better design, improved recovery and re-use, more efficient resource management, the performance of materials recovered from wastes, and, the procurement, planning, design, construction, operation and logistics of waste and resource management facilities.
