<![CDATA[Delays in river embankment construction can hinder the timely completion of infrastructure intended to mitigate flooding and slope failure. This study aimed to assess schedule acceleration using the fast-track method for stone masonry work on the Kedunglarangan River Improvement Project in Pasuruan Regency, Indonesia. The analysis used project schedules, work breakdown structures, activity quantities, and field productivity data to identify remaining activities and establish scheduling relationships in Microsoft Project. Critical activities were rescheduled through overlapping execution, with selected finish-to-start (FS) relationships modified to start-to-start (SS) relationships using specified time lags. The project experienced an approximately 10% progress shortfall between Weeks 2 and 8, requiring adjustments to the remaining structural and masonry work. The accelerated schedule resulted in a total project duration of 82 days, compared with the original duration of 94 days, representing a reduction of 12 days, or approximately 12.77%. These findings indicated that overlapping critical activities could shorten the construction schedule while maintaining the necessary activity dependencies. However, quantified cost outcomes were not provided, preventing conclusions regarding potential cost savings. The study concluded that the fast-track method provided a viable scheduling alternative for this project, subject to verification of activity dependencies, resource availability, and construction feasibility prior to field implementation.]]>
