Abstract

In general, the completion of a project must be in accordance with a binding contract agreement, but during its implementation, unexpected obstacles and obstacles can occur, resulting in delays. Project delays affect weekly performance results, and project final results and affect the performance appraisal of project implementers. Delays can be seen through weekly performance progress according to schedule. Delays can be prevented by speeding up the existing schedule. This study raises the issue to perform an acceleration analysis on the schedule using the Precedent Diagram (PDM) method which is combined using the fast track method and then compares it with the Precedent Diagram (PDM) method combined with crashing and then determines which method is used in accordance with this research. . In this study the case study experienced a delay in the 18th week where the progress of the plan of 16.60% was only realized by 11.21% resulting in a deviation of 5.4%. This delay occurred due to delays in the construction of Tower Crane, delays in the arrival of materials and in areas experiencing a pandemic which, under restrictions on activities carried out by the government. This delay occurred in the duration of project completion where the planned duration of 366 days was delayed to 390 days. This greatly affects the performance results of subsequent activities. The results of the analysis obtained using the precedent diagram method combined with the Fast-Track method are able to overcome delays by returning the initial scheduling late Return according to the scheduling plan, which is 366 days, without any additional costs and the results of the analysis using the PDM method combined with the crashing method can make the duration faster than the plan duration, which is 359 days or 7 working days faster and the additional cost is 1.02%.
