Abstract

Preparatory work in a construction project generally includes the fulfillment of work facilities, field investigations, and licensing, and is typically non-structural. The implementation of the Jakarta Sewerage Development Project Zone 1, Package 2: Construction of Sewers in Area 1-1, which is currently still in the preparatory work stage, is experiencing significant issues. Specifically, the project is facing a very complex licensing process, resulting in minimal work progress. This is due to the project planning phase not adequately considering the timeframe required for obtaining an implementation permit. Therefore, this paper analyzes the project timeline to identify project performance during the preparation period before the main project work implementation stage. In this study, the Critical Path Method (CPM) scheduling method was applied to the project to determine the activities on the critical path, utilizing the Microsoft Project application. The analysis identified that the activities on this critical path include Document Submission Work, Shaft Location C-8.1 Work, 8-span Pipe Jacking Work, Diversion Chamber Work, and Contract Closing. The analysis of the relationship between the licensing process and the critical path of the Master Schedule, as determined by the CPM method, revealed a delay in the start time of Shaft work from the planned June 3, 2024, to June 21, 2024, representing a 17-day delay from the original plan.

Abstract

In a construction project, preparation work typically includes tasks related to setting up work facilities, conducting field investigations, obtaining permits, and non-structural activities. The Jakarta Sewerage Development Project Zone 1, Package 2, which involves the construction of sewers in Area 1-1, is currently in the preparation phase and is experiencing challenges due to a complex permit process. This has led to minimal progress as the initial project planning did not consider the time needed to secure the necessary permits for implementation. The author is therefore evaluating the project timeline to gauge performance during the preparation phase before actual construction begins. This study utilizes the Critical Path Method (CPM) scheduling technique in Microsoft Project to pinpoint critical activities. Upon analysis, it was found that the budget plan for Package 2 of the Jakarta Sewerage Development Project (Zone 1) was detailed and included various work descriptions, with a total budget of IDR 862,292,086,196. However, delays have occurred, resulting in a 17-day setback in the project schedule, necessitating work acceleration. To bring the project duration back in line with the original schedule as per the contract, acceleration was required. This was carried out on the Shaft Construction C-8.1, which was initially set to take 80 days but was shortened to 63 days through time acceleration, incurring a cost of IDR 23,279,288.
