The construction industry faces numerous safety challenges. Effective safety training is critical to reducing workplace accidents and injuries. However, despite the mandatory implementation of safety standards and regulations, traditional safety training methods are inadequate in effectively preparing workers to build safely. With the advent of virtual reality and metaverse technology, this study aims to transform the traditional instruction-based construction safety training into an immersive, interactive, and engaging learning experience through a game. Participants are placed in simulated construction scenarios where they are tasked to identify and respond to potential hazards. As a pilot study, this work developed the Construction Guardian, which simulated the fall hazard in a real construction project by utilizing Unreal Engine 5 Datasmith plugin with the Building Information Model (BIM) in Navisworks. Engaging the participants in a virtualized recreation of the real-life project enhances their sense of situational awareness, allowing participants to immerse themselves in realistic scenarios before stepping onto the actual job site, while also monitoring the training performance of each participant.
