Analysis of materials and cash flow through building information modeling in construction projects

In construction projects, variations in material consumption, differences in expenditures and inconsistencies in resource utilization are among the major challenges in material and cash flow management processes. The inability to effectively manage these factors leads to a lack of coordination, resulting in increased costs, resource waste and delays in project delivery timelines. Therefore, with the increasing complexity of construction projects, the need for computer-based and automated systems has become inevitable. In this context, the primary aim of the research is to develop a model that can track material and cash flow in construction projects. Within this scope, a 3D model was created using Building Information Modeling (BIM) with the help of Revit ve Navisworks software. The model was enhanced by incorporating the time factor at the 4D level and cost data at the 5D level, leading to the development of a virtual simulation of the project. In the proposed method, the developed 5D model, through BIM integration, offers a more advanced construction management approach compared to traditional methods. Additionally, project processes are optimized with simulations that incorporate time-based cost management. In this process, different aspects of project management are evaluated to examine how workflow can be optimized under specific scenarios. Furthermore, each scenario is analyzed based on cost, time and resource utilization criteria and its impact on the project process is comparatively assessed. The results indicate that BIM-based systems improve the financial management of projects, ensuring greater transparency and accuracy. As a result, budget estimates become more accurate, cost overruns are reduced and decision-making processes are accelerated, ultimately enhancing project success rates. Based on the research findings, it is anticipated that the widespread adoption of 5D BIM systems in the construction industry will contribute to the development of more efficient and sustainable projects.
