Identifikasi Faktor-Faktor Penyebab Rework Pada Proyek Pembangunan IPA Brayan Kapasitas 500 Liter/Detik

Abstract

The Brayan Water Treatment Plant with a capacity of 500 Liters/Second is a project that is expected to improve the distribution of clean water to various areas that need it. However, in its implementation, the Brayan IPA project experienced delays, one of the causes of which was rework. Rework is very common in the construction industry, so no matter how well construction management is handled, rework cannot be completely avoided. This has a negative impact on construction implementation. However, rework can be minimized by taking preventive measures to avoid it, starting with identifying the factors that cause rework. The purpose of this study is to determine whether design, managerial, and resource factors influence rework and what factors are the main causes of rework in the Brayan Water Treatment Plant Construction Project with a capacity of 500 Liters/Second. In this study, 37 respondents participated, including contractor teams and workers. The collected respondent data was analyzed using SPSS 26.0, yielding results on the relationship between design, managerial, and resource factors to rework, as well as the primary causes of rework. The results of this study indicate that design and documentation factors, managerial factors, and resource factors collectively influence the occurrence of rework, with a calculated F value > table F value (19.509 > 2.891). The managerial variable has a calculated T value of 2.554, while the table T value is 1.692, so the calculated T value is greater than the table T value (2.554 > 1.692), and the significance level is 0.016 < 0.05. Therefore, it can be concluded that managerial factors significantly influence rework.
