Life Cycle Cost Analysis of Pavement Using BIM: Review

The methodology of Life Cycle Cost Analysis (LCCA) for road pavements and proposes the integration of Building Information Modeling (BIM) to enhance the analysis process. LCCA involves estimating the total cost of a project by considering initial construction costs, operational expenses, and maintenance costs. To minimize the life cycle cost of pavements, it is crucial to address the original cost alongside the requirements for pavement preventive maintenance. The study highlights the utilization of Economic and Sensitivity Analysis to examine LCCA results using key financial indicators such as Net Present Value (NPV) and Internal Rate of Return (IRR), considering various influential input parameters. By employing software instead of manual estimation, the potential for human error is significantly reduced while saving time. Furthermore, the study emphasizes the growing adoption of BIM in the field of infrastructure and proposes the integration of LCCA within the BIM environment. This integration aims to evaluate different design choices and establish effective maintenance plans. By utilizing BIM tools, a detailed analysis of the pavement's life cycle can be achieved, thereby facilitating the prediction of sustainable pavement solutions through the comparison of alternatives. In conclusion, this work contributes to the advancement of sustainable pavement practices by offering a comprehensive approach that combines LCCA, Economic and Sensitivity Analysis, and BIM. The proposed methodology has the potential to enhance decision-making processes related to road pavement construction, maintenance, and cost-effectiveness, leading to more efficient and sustainable infrastructure development.
