Abstract
This research aims to study and apply the Repetitive Scheduling Method (RSM) integrated with the Time-Cost Trade-Off method to generate a project planning that is suitable for both duration and cost for two road construction projects. The information on the duration and costs of each activity were collected and analyzed using the RSM and Time-Cost
Trade-Off methods by increasing the number of group workers and equipment or machines in the Controlling Sequence. The results showed that the suitability of the first project was at the project duration of 40 days, compared to the CPM method, reducing the project duration by 39.39%, and reducing the total cost of the project by 5.11%. For the second project, the suitability was at the project duration of 82 days, compared to the CPM method, reducing the project duration by 35.94%, and reducing the total cost of the project by 4.74%. Therefore, this research illustrates the application of the Repetitive Scheduling Method (RSM) integrated with the Time-Cost Trade-Off method that can be applied to projects. The proposed method can effectively reduce the duration and cost of road construction projects.
