Cost and Time Comparison Analysis Using Microsoft Project (Case Study: Phase VII Work of the Surabaya Tanjung Perak Berlian Pier Structure Strengthening Project)

Abstract

Sometimes the execution of a project does not proceed smoothly because there are barriers that impede the present work. Uncertain weather conditions are one of the most common challenges encountered in the field during the Tanjung Perak Diamond Pier Structure Strengthening project in Surabaya. This is because the initial planning did not account for the weather conditions that would occur during the project's implementation. As a result, rescheduling is carried out to generate a reasonable and realistic timetable. Many strategies are employed in scheduling, with the expectation that the method will help in planning and scheduling. The goal of this research is to determine the time necessary for project implementation after rescheduling. This research is analytical in character. Secondary data, such as schedules and Budget Plans (RAB), are collected by directly requesting the necessary data from related parties, then evaluating the initial schedule, and finally preparing a new schedule using Microsoft Project tools and the Critical Path Method (CPM).  The results of this study obtained a rescheduling duration of 99 days, 22 days faster than the actual planned duration of 121 days, and a fee of IDR. 28,535,441,605 of the initial planned cost of IDR. 35,017,986,296.10.
