ABSTRACT
Construction projects have unique, dynamic, and complex characteristics; therefore, frequent inaccuracies between planning and implementation are found. It generates a budget change as a consequence. Project delays also occurred in Entikong PLBN Multi Purposes Building Project, West Kalimantan; therefore, an “addendum” time had to be submitted for the 31st week. According to the identified problems, the purpose of this study is to analyze the time acceleration to achieve project time reduction and cost savings. The analytical approach uses a fast-track method widely applied and proven effective in time reduction through overlapping the critical activities. The result of the project schedule shows that the normal duration of 359 days turned into 302 days; therefore, a reduction in time of 57 days can be obtained. Time reduction through project acceleration was 15,88% without causing an overallocated resource. The time reduction impacts project cost efficiency, especially in indirect cost savings of Rp 17.345.955. Implementing the fast-track method by paying attention to the allocation and availability of resources provides an optimal schedule. Thus, the risk of unrealized activities due to acceleration can be minimized.
