Abstract

The construction industry is one industry that contributes significantly to a country’s economic growth. A construction project is successful if the implementation meets the three components namely the cost, time and quality. Project financing is one of the important components in the construction project activities that define how much budget should be provided in a construction project activity. Cost components used for feasibility studies, design alternatives are possible, and the selection of optimal design in a construction project. Inaccuracy in analyzing construction costs can have a negative effect on the entire construction process and all parties involved. A system dynamics approach is a simulation method in solving real-world problems to describe relationships among variables in complex real systems. The expected results from this research are quantitatively in the form of reinforced concrete work costs which are influenced by direct costs and indirect costs that can be updated in real-time. From the simulation results, a graphical analysis through the model output will be obtained and all the resulting scenarios can be compared. In addition, with sensitivity analysis through model scenarios, it can accommodate all possible deviations that will occur in the future, including risk factors in the future.
