Abstract

Project financing is one of the important components in the construction project activity that define how much budget should be provided in a construction project activity. Financing of the project includes the supporting components which influence each other to the total project cost. Planning of project costs with components such as material, wage and equipment costs, may change with respect to external factors and general economic conditions in the country, thus requiring the prediction of unit price of labor’s wage as one of its components. The dynamic wage financing simulation system using Vensim software to identify causal relationships between variables (CLD: Causal Loop Diagram) as well as the equation between variables (stock flow diagrams) is ideal for use in predicting the unit price of a wage of a construction worker. This financing system can be used to identify more clearly the relationship between the sub-components of labor costs, facilitate the simulation and decision-making in order to achieve the most optimal project costs in accordance with the interests of budget users. The results of the labor cost financing model have been verified and validated with E1 = 3.65% <5% and E2 = 6.26% <30%, so that it can be used to predict wage changes of workers for subsequent budget planning in order to achieve effectiveness, efficiency and accountability in the implementation of construction projects.
