Abstract

Time delays in construction projects are a common issue that significantly impacts both project costs and overall success. This study aims to optimize the duration of a four-story shop-house construction project in the Malalayang area of Manado City by applying the crashing method. This technique is employed to accelerate activities along the critical path through the addition of overtime work hours, without compromising the quality of the output. The analysis was conducted using the Critical Path Method (CPM) to identify critical project activities, followed by a quantitative simulation of schedule acceleration. The results indicate that the project duration can be reduced from 175 days to 148 days—an acceleration of 27 days—with an additional cost of IDR 32,723,678.95. This additional cost is considered acceptable given the time efficiency gained. These findings demonstrate that the crashing method is an effective and feasible strategy for schedule optimization in the management of building construction projects
