Relationship of Construction Waste Causes and BIM-IBS Practices in Reducing Waste through Project Design Stage

Lack of Industrialized Building System (IBS) deployment in the construction industry and issues that arise during the design phase both contribute to an increase in waste. Thus, the government introduced BIM in IBS construction as a technology to improve project quality while lowering project costs. In this study, the effectiveness of BIM-IBS and the identification of waste source, awareness of waste cause, and implementation in BIM-IBS were examined. The purpose of this study is to evaluate the efficacy of BIM-IBS practices for waste reduction at construction projects and to establish a link between the causes of waste and the effectiveness of BIM-IBS practices for waste reduction during the design phase. A review of the literature and a questionnaire survey were done to determine the study's goal. The required values, such as Cronbach's alpha, mean value, standard deviation, and correlation, have been determined by analysis of the data using the SPSS Software. This study was able to ascertain a very important connection between waste cause, design phase issues and the advantages of BIM and IBS in lowering construction waste in the construction industry. The vast majority of respondents concurred that using BIM and IBS in the construction process is very effective and efficient in reducing construction waste in the industry.
