PERBANDINGAN RENCANA ANGGARAN BIAYA AWAL DENGAN RENCANA ANGGARAN BIAYA SETELAH ADDENDUM PADA PROYEK GEDUNG LABORATORIUM SMAN 10 DENPASAR

Abstract

A common issue encountered in construction work is the occurrence of changes, which can take the form of differences in volume, additions or reductions in work scope, delays in work, or extensions of work time for specific reasons. Solutions or actions are essential to prevent issues that could hinder the construction process and the final outcome of a project. Therefore, alignment between the e-catalogue Bill of Quantities (BoQ) and the contractor's BoQ is necessary. The objective of this study is to determine the magnitude of price shifts between the initial BoQ and the contractor's BoQ after the addendum and the causes of these cost shifts. This study is a quantitative descriptive study comparing the existing RAB with the RAB after implementation to determine the price difference. Primary data used includes changes in work volume during implementation based on field backups and Shop Drawing diagrams. Primary data also includes the initial Cost Estimate, technical specifications, and the Unit Price List for Work. Data analysis was conducted by calculating changes in work volume during implementation. The results of the study show that there was a reduction of Rp 743.67.000,00 from the initial contract amount of Rp 6.541.339.239,00 to Rp 5.797.712.370.00. This occurred due to discrepancies in the drawings and the installation conditions on-site, resulting in additional and reduced work.
