Analysis of Ramp on Off Costs And Time Using the Earned Value Analysis (EVA) Method

Abstract

In the construction of a project, the contractor has problems where the project is delayed. Therefore, it is necessary to make a system that is made to control costs and time so as not to experience delays and losses. In this study, the control is carried out using earned value analysis which aims to control costs and time with BCWS, BCWP and ACWP, which then calculates the cost and time performance index to determine the estimated cost and time to complete the project. The results of this study show that at the end of the 91st week, the calculation of costs is still below the budget. Estimated cost for project completion of Rp 75,803,028,234.56 is still smaller than the contract value. To return the project costs to the position according to the plan, a CP1 value of 0.95992 is needed. The estimated time required to complete the project is 127.43 weeks, while the completion time according to the contract value is 117 weeks. So the estimated project completion requires an additional 10.43 weeks or 74 days from the end of the planned schedule. To restore the project schedule according to the plan, an SPI value of 1.25133 is required.
