Pemodelan Struktur Bangunan Jembatan Menggunakan Software BIM Revit 3D (Studi Kasus: Pembangunan Jalan Tol Probolinggo – Banyuwangi Paket 3)

Abstract

Building Information Modeling (BIM) is a digital model–based technology that is increasingly applied in infrastructure planning; however, its implementation in bridge structural planning in Indonesia remains limited and is generally not yet optimally utilized at the level of detailed three-dimensional (3D) modeling. This condition causes the planning process to still rely heavily on two-dimensional (2D) drawings, which have limitations in representing geometric relationships among structural elements and in detecting design inconsistencies at an early stage. This research adopts a case study of the Blimbing Bridge in the Probolinggo–Banyuwangi Toll Road Project, where the complexity of interactions among pile slab, abutment, girder, and bridge deck elements has the potential to generate geometric inconsistencies that are difficult to identify using 2D drawings. The objective of this study is to analyze the application of BIM 3D in the structural modeling of the Blimbing Bridge and to evaluate its capability in identifying geometric inconsistencies and improving design coordination. The research employs an applied quantitative approach with a case study method, utilizing technical planning data including construction drawings, structural element dimensions, and design elevations. BIM 3D modeling was carried out using Autodesk Revit by developing detailed models of the main structural components, namely pile slab, abutment, girder, and bridge deck, in accordance with applicable design standards. The results indicate that the use of BIM 3D improves the consistency of dimensional and elevation information among structural elements and facilitates design coordination through an integrated digital model that functions as a single source of information. This study contributes a BIM 3D modeling workflow for bridge planning that enhances visualization accuracy and design reliability, thereby providing a reference for the development of BIM-based bridge planning practices in infrastructure projects in Indonesia
