REDUCING REINFORCED CONCRETE MATERIALS WASTE IN CONSTRUCTION PROJECTS USING BUILDING INFORMATION MODELING IN EGYPT

Reduced Reinforced Concrete Material Waste (RRCMW) is recognized as a major issue that must be controlled in building projects. The primary goal of the study is to demonstrate the significance of BIM in construction and the importance of BIM in reducing reinforced concrete material waste. To achieve the study's goal, a questionnaire survey is undertaken to estimate the benefit of using BIM in Egyptian building projects. According to the survey results, about 41% of respondents are believed that BIM may reduce project costs by 16% to 20% when compared to the traditional method. In addition, the proportion of variations in reinforced concrete amount survey between traditional methods (AutoCAD) and (Revit) is discovered to be 44%, with a range of 11% to 15%. Approximately 46% of respondents are believed that BIM eliminates design errors, with a percentage ranging from 21% to 25%, and about 51% are believed that BIM helps in reducing rework, with a total percentage ranging from 21% to 25%. Then, case studies of building ("Residential projects") and infrastructure ("Bridges projects") projects are analyzed to determine the difference between waste minimization using traditional methods and waste minimization using BIM. Waste management is a critical issue since it is the only approach to optimize waste throughout the project phases. As a result, factors managing (RRCMW) are extracted, and BIM software should be used to manage these factors in order to optimize waste. The relevant BIM applications are used in this case study: site utilization planning, quantity take-off, 3D coordination, visualization, digital prefabrication, design validation, "design review and clash detection," and optimized workflow and communication structure. So, based on the preceding case studies, it is discovered that using BIM is far more successful and economical than using the traditional method, because it aids in the resolution of many issues before and during construction, such as clash detection, material storage, material ordering, and so on. As a result, while BIM is not widely used in Egypt, engineers should be familiar with it because it will be a vital tool to reduce waste in the future.
