Abstract

The Cost Budget Plan (CBP) is the main aspect of project implementation in calculating the estimated overall costs required to establish a construction project. This research aims to determine the percentage value of the work components that form the Cost Budget Plan (CBP) and determine the implementation budget or actual costs incurred for each job. The research was carried out in urban slum areas, one of the locations reviewed was Ketapang Village, which is located in Mauk District, Tangerang Regency, Banten Province. Ketapang Village. Data collection in this research used calculations of working drawing volumes based on unit prices from Banten Gubernatorial Regulation No. 39 of 2021 and implementation volumes using unit prices based on surveys by the Community Self-Reliance Agency. In processing the CBP data, the overall CBP recapitulation calculation results were IDR 81,001,345. The largest cost of components forming the CBP occurred in architectural work amounting to IDR 36,213,105 with a percentage value of 44.71%. The wage component which has a percentage of 14.81% shows that the material component that makes up a simple house is 85.19%.

Abstract

Rework in construction refers to the activity of repairing or redoing work that does not meet quality standards, causing delays and increased costs. The aim of this research is to identify the causes of rework in building structures, with a case study of four types of houses in one of the housing complexes in South Tangerang City. This research focuses on the use of quality improvement tools such as Pareto Charts. Pareto diagrams, based on the Pareto principle which states that most consequences come from a small number of causes, are used to identify and prioritize the causes of rework. The types of work that most frequently result in rework will be monitored more closely to minimize future errors. Data collection through field observations by calculating the frequency of repair work. The results of the analysis show that most rework is caused by some type of repeated error. The implementation of Pareto resulted in 75% of rework resulting from 50% of the causes. There were 5 causes of rework occurring which were analyzed, namely inappropriate dimensions, elevation differences, slanted formwork, ends of reinforcement that were not connected, and reinforcement that needed cleaning. This implementation helps in solving these 5 problems and provides lessons for other similar projects
