Julistyana Tistogondo — 2025-05-20

Every construction project inevitably involves project execution, including managing project completion timelines. Time management is crucial for any construction project, particularly when it comes to cost details that significantly impact project success. In specific projects, such as residential homes, shophouses, condominiums, and other repetitive projects, completion times are often inefficient. The Line of Balance (LoB) method is a technique used to determine the duration required to complete a construction project. The Line of Balance (LoB) method, also known as the balance line method, is highly effective for projects involving numerous repetitions, such as highways, housing developments, and similar buildings. This thesis utilizes the CitraGarden Sidoarjo accommodation project as a case study. The Existing Schedule method estimates a completion time of 53 weeks for a single house, whereas the project time for four houses totals 212 weeks, as illustrated by the S-curve project data. In contrast, for two pairs or four houses, the Line of Balance (LoB) method requires 113 weeks to complete the project. Thus, the Line of Balance (LoB) method accelerates the calculation of project completion time for the CitraGarden Sidoarjo housing project.
