Traditionally, civil engineering infrastructures have been represented through two-dimensional (2D) drawings, which can lead to interpretation errors and jeopardize engineers' understanding of complex projects. However, with the development of building information modeling (BIM) methodology, civil engineering projects can now be virtually modeled in three-dimensional (3D), offering a more accurate representation. Augmented reality (AR) tools can be linked to BIM models for educational purposes, allowing for a more immersive and interactive learning experience. While previous studies have focused on improving the visualization of mechanical and civil engineering drawings, this study presents the development of a low-cost AR tool for visualizing BIM models and its application in civil engineering courses. To achieve this, the main state-of-the-art AR software was compared for their characteristics and functionalities, and the software, Unity, was selected to develop an AR visualization tool. The application of this tool was then presented, along with an analysis of its benefits when introduced into two civil engineering courses at the University of Castilla La Mancha (UCLM) in Spain: Descriptive geometry, and Design work of a structure. Overall, the results of the study suggest that the integration of AR tools into civil engineering education can enhance students' learning experience and improve their understanding of complex projects.
