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

Abstract

The application of Building Information Modeling (BIM) as a digital-based modeling technology has continued to grow in infrastructure planning. However, the implementation of BIM in bridge structural planning in Indonesia remains limited, particularly at the detailed three-dimensional (3D) modeling stage. In practice, bridge planning is still predominantly based on two-dimensional (2D) drawings, which have limitations in representing geometric relationships among structural elements and are less effective in identifying potential design inconsistencies at the early planning stage. This research was conducted on the Paiton Bridge, which is part of the Probolinggo–Banyuwangi Toll Road Project. The bridge structure consists of several main structural elements, including foundations, pile caps, piers, abutments, pier heads, girders, and deck slabs, which have complex geometric relationships. Such complexity may lead to design coordination issues when represented solely through 2D drawings. Therefore, this study aims to analyze the application of BIM 3D in the structural modeling of the Paiton Bridge and to evaluate its capability in supporting the identification of geometric inconsistencies and design coordination. The research method employed is an applied quantitative method using a case study approach. The data used include construction drawings, structural element dimensions, and design elevation information obtained from project planning documents. The modeling results indicate that the use of BIM 3D improves the clarity of visualization of relationships among structural elements and enhances the consistency of dimensional and elevation information within an integrated digital model. The resulting model also facilitates design coordination by providing a comprehensive structural representation, enabling potential geometric inconsistencies to be identified earlier during the planning stage. Consequently, the application of BIM 3D in the planning of the Paiton Bridge contributes to improved design reliability and construction readiness
