In the implementation of construction project activities there are thre things that influence the success and failure of the project: time, cost and quality. The success of a project is usually seen from the timing of completion which is relatively short but without neglecting the quality of the project work. Appropriate and targeted project management and management are required to ensure the time, cost, and quality of the project. This is certainly to avoid a variety of undesirable things such as late settlement, swelling costs, quality failures, and so on that could have an impact on project failure and the emergence of the cost of fines. The purpose of this study is to calculate changes in cost and time of project implementation with alternatives to additional working hours (overtime) comparing the results between normal and cost changes after the addition of working hours (overtime). The data used in this research is secondary data obtained from contractor implementing. Arrow diagram The results program are critical paths and cost increases due to the addition of working hours (overtime) while the result of the time cost trade off method is the acceleration of duration and the increased cost due to the acceleration of duration in any accelerated activity. The results of this study indicate that the total project time and cost under normal conditions is 508 days at a cost of Rp 22.240.655.701  with the addition of 3 hours of overtime work in the duration of crashing 485 days and at a cost of Rp 23.252.220.373,34

The Project Scheduling Game is an IT-supported simulation game that illustrates the complexity of scheduling a real-life project. The project is based on a sequence of activities for a large real-life project at the Vlaamse Maatschappij voor Watervoorziening, which aims at the expansion of the capacity to produce purified water. The basic problem type that we use in the game has been described in the literature as a CPM (critical path method) network problem, and focuses on the time/cost relationship in each activity of the project. Indeed, by allocating resources to a particular activity, the manager decides about the duration and corresponding cost of each network activity. The manager schedules the project with the negotiated project deadline in mind, focusing on the minimization of the total project cost.

The construction of new shipyard in the Cilacap area is one of the best ways to reduce the accumulation of vessels. The construction of shipyard has many risks, one of the risks that can occur during the construction of the shipyard is in terms of cost and time. Project scheduling is a tool to make sure the project finished on time. This paper discusses project scheduling and cost calculation using Critical Path Method (CPM) and Program Evaluation Review Technique (PERT) method for Graving Dock project development in Cilacap. Project scheduling is useful to indicate the relation of each activity to another. This paper will discuss the critical activities during Gravity Dock development and the duration for the whole project using CPM. The next step is to determine the probability of the completing project that can be finished within the time frame using PERT. Based on the CPM analysis, the probability of Graving Dock project can be finished in 204 days is 79,81 %. The total cost for Graving Dock project in Cilacap is Rp. 6.486.122.769.
