Infrastructure development projects are widely acknowledged as some of the most complex and challenging projects to undertake. The construction of bridges, in particular, has proven to be a significant safety risk for workers, with a considerable number of accidents reported on construction sites. There is a lack of comprehensive training programs specifically designed for bridge construction safety, and only a few studies have explored the use of both AR and VR to enhance safety training in construction. As such, this research aims to improve the safety of bridge construction sites through the implementation of Augmented Reality (AR) and Virtual Reality (VR) in safety training. The proposed approach seeks to address the gaps in existing traditional and VR safety training, which often focuses on specific hazards rather than the project as a whole. The study begins with a thorough investigation of the potential dangers on bridge building sites, which were then used to design the training scenario. The development and testing of AR and VR models resulted in a significant improvement in trainees' knowledge before and after training. However, major rooms of improvement in the training methods were identified and implemented in the second phase of the study. These included the need for a pretraining model to teach trainees how to use the technologies and the addition of new movement methodologies to prevent dizziness. The results of the study demonstrate that the combination of AR and VR technologies can significantly enhance bridge construction site safety training. The use of a pretraining model and allowing trainees to choose their preferred movement approach can further improve the training's effectiveness. The intellectual merit of this study lies in the development of a new approach to bridge construction safety training that leverages the latest technologies to improve the learning experience. The benefit to the industry is a safer work environment for bridge construction workers, reducing the incidence of accidents and injuries.
