Assessing the role of Building Information Modeling (BIM) in enhancing project performance and sustainability in multi-story Building construction.

This research evaluates the influence of Building Information Modeling (BIM) on improving project performance and sustainability in the construction of multi-story buildings. It explores how BIM enhances the efficiency and sustainability of these projects by leveraging its advanced features to assess its effects on project execution, resource optimization, and environmental sustainability. A thorough analysis is provided of BIM's functionalities and its integration for 3D modeling through various BIM tools, as well as software tools for scheduling, costing, energy analysis, and optimization. The study delves into contemporary construction practices through an extensive examination of these aspects, offering nuanced insights. A key component of this research is the comparative analysis of two distinct building structures: one using precast concrete (PC) and the other using reinforced concrete (RC). Detailed 3D models created with Autodesk Revit software capture the complexities of both PC and RC buildings, highlighting the advantages and challenges inherent in each construction method. The analysis of the PC building design reveals innovative strategies that maximize wider spans to reduce the number of column and beam members, streamlining construction processes and enhancing structural integrity. Using analytical data and scheduling functionalities within MS Project software, the study meticulously outlines construction tasks and timelines, revealing a 39% reduction in the total time span for the PC building compared to the RC building. Additionally, comprehensive cost estimates derived from various sources shed light on the economic implications of different construction methodologies using MS Excel. The findings indicate a significant cost advantage for the PC building, with a 15.15% reduction in total material and installation costs compared to the RC building, underscoring the economic viability and potential savings of precast concrete construction over traditional methods. Furthermore, the integration of Composite Precast Concrete (CPC) frames in the PC building is identified as a transformative strategy with significant sustainability implications. By utilizing CPC frames and sustainable building materials, the study aims to enhance structural efficiency, reduce carbon emissions, and contribute to a greener, more sustainable future in construction. Empirical data show substantial sustainability benefits, with the PC building achieving a notable reduction in carbon emissions of 85.41 kg CO₂/m², a 19% decrease compared to the RC building. In conclusion, this study highlights the pivotal role of Building Information Modeling (BIM) in enhancing project performance and sustainability in multi-story building construction. Through integration with various software tools and a detailed comparative analysis, BIM is shown to streamline processes, optimize resources, and promote environmentally conscious construction practices. The study significantly contributes to the ongoing discourse on BIM's essential role in shaping the future of the construction industry, providing invaluable guidance for stakeholders navigating the evolving landscape with foresight and resilience in an era marked by innovation and sustainability.
