Implementasi dan Evaluasi Visualisasi Augmented Reality (AR) Desain Jembatan Berbasis Building Information Modelling (BIM) Menggunakan Autodesk Revit dan Aplikasi Gamma AR

In the construction industry, design visualization or construction drawings are very important, this also applies to bridge infrastructure. However, conventional bridge design visualizations often fall short in effectively conveying technical information intuitively. Therefore, innovative solutions are needed, one of which is the application of Augmented Reality (AR) integrated with Building Information Modelling (BIM) systems. This study implements a bridge model created using Autodesk Revit into the GAMMA AR application for direct visualization at the physical location of Jalan Bengkalis Bridge. The research stages include developing the bridge BIM model, integrating BIM with AR, and conducting field testing using task-based testing and heuristic evaluation methods. The integration process was successfully carried out through two methods: direct upload of .IFC files and synchronization via Autodesk Construction Cloud. The AR visualization results demonstrated that the bridge model could be displayed with high accuracy, with an average deviation of only ±1 cm from the original BIM design. However, some technical limitations were encountered, such as the absence of a tilt adjustment feature and limited rotation controls. Despite these issues, the GAMMA AR application was generally effective in conveying design information, enhancing technical comprehension, and accelerating on-site validation processes. Based on the implementation and evaluation results, it can be concluded that AR technology holds significant potential for technical, educational, and managerial applications, serving as an integral part of digital transformation in the construction sector.
