| Abstract | India is pushing its economy to the next level, which also means that more construction projects are taken places. This, consequently, also increases the generation of waste from construction projects. In order to reduce this waste production, it is important to assess the factors that are generating construction waste. This study aims to identify and examine the critical factors that are generating construction waste in Indian building construction projects. In achieving this objective, mixed quantitative and qualitative methods are applied. The compiled factors from previous studies were validated by five experts. Pilot study was conducted before finalizing the questionnaire for data collection. The factors generating construction waste were examined from 196 valid questionnaires collected from respondents working in 75 contractor firms operating in Hyderabad, India. The top-ten factors, considered as the important factors in generating waste are: 1) Waste from application process, 2) Inappropriate site storage, 3) Design changes, 4) Lack of skilled labor, 5) Offcuts from cutting materials, 6) Lack of onsite waste management plans, 7) Lack of supervision, 8) Lack of training to the workers, 9) Poor craftmanship, and 10) Inappropriate material handling. In providing insights on how the factors work in practical context, interviews with project managers of four large building projects were conducted. Site observations were also used to support and understand the findings from the interviews. The results from interviews and observations were analyzed for each case (case wise analysis) and cross case analysis for comparison. From the cross-case analysis, it was found that the common causes can be grouped into four categories, causes related to workers, management, process, and engineers, with the dominant causes were under workers category. Approaches applied to reduce or minimize the waste generation are also presented and discussed in this research as recommendations to make construction projects greener. |
