An Analysis of Time and Cost Using the Critical Path Method (CPM) in the ITS Bank Building Construction Project

Abstract

The provision of banking service facilities within a campus environment is an essential requirement to support the smooth running of academic and operational activities in higher education institutions. Institut Teknologi Sepuluh Nopember (ITS) responded to this need by constructing a bank building as part of the development of a modern and digital campus ecosystem. The construction project of the ITS Bank Building was scheduled for a duration of 120 calendar days, with a maintenance period of 180 calendar days. During its implementation, the project encountered several obstacles that led to deviations between the planned schedule and the actual progress on-site. In the twelfth week, the planned progress of 37.274% was not achieved, as the actual progress only reached 32.018%, resulting in a delay of –5.256%. Weather conditions and the complexity of the work were the main factors contributing to the delay. This study aims to analyze the project's critical path and optimal completion time by applying the Critical Path Method (CPM) and the Fast Track method. Fast Track is an acceleration technique that allows project activities to be carried out in parallel in order to shorten the overall project duration. The analysis involves identifying critical activities using CPM and then rescheduling the project using the Fast Track approach to determine the optimal project duration.Based on the analysis, several activities were identified as being on the critical path, namely: 1) road and parking work, 2) drainage and bridge work, 3) landscaping, 4) connection fees, and 5) final cleaning work. The results show that the optimal duration after implementing the Fast Track method in the ITS Bank Building construction project is 112 working days, which is a 6.7% reduction from the initial plan of 120 days.
