Perencanaan anggaran biaya pada pekerjaan struktur jembatan berbasis 5D BIM

Abstract

The construction sector in Indonesia faces fundamental issues related to productivity, financial aspects, and technology adoption, which are exacerbated by a low level of digitalization. Building Information Modeling (BIM) has produced a solution, particularly in enhancing the accuracy of cost calculations that are essential for budget control and project management. This study focuses on investigating the implementation of the fifth dimension (5D) BIM to cost planning of structural work. The chosen case study is the Planjan-Baron-Tepus New Road Bridge Project in Gunung Kidul Regency, Yogyakarta, with the targeted output being a more accurate and efficient Cost Budget Plan (RAB) for the concrete bridge structure work. The steps undertaken began with modeling 2D re-drawings into a 3D model using Tekla Structures software, which is already integrated with Vico Office software as the 5D (cost estimate) processing software. This integration eliminates the need for IFC files. The research results indicate that the application of BIM 5D significantly enhances the efficiency and accuracy of bridge project cost planning. Detailed 3D modeling and dimensional integration enable a dynamic cost budget plan (RAB), in-depth cost analysis, and real-time control. In this research, the application of Building Information Modeling (BIM) 5D in the cost estimation of the bridge structure yielded a Cost Budget Plan (RAB) amounting to IDR 14.533.619.827,25.
