Abstract
Although hands-on practices are considered the most effective training method for crane operators, they are always expensive and dangerous to be performed at the actual worksite. As an alternative, virtual reality and simulator technology provide a close-to-reality experience in lifting operation while minimizing costs and hazards. However, the virtual environment in current training systems are static and designed ahead of time rather than representing an as-built construction site with its dynamic construction resource (workers, equipment, materials). Such a drawback greatly limits the effectiveness of virtual training systems. To advance virtual training for crane operators, this research presents a framework toward constructing as-built virtual training environments by integrating Building Information Modeling (BIM) and real-time location tracking technology in a virtual environment. Implementing the proposed framework, a virtual training system for lifting tasks at an actual construction site was developed. The results of a pilot test show that such an approach can construct as-built work scenarios effectively and potentially assess and improve operator proficiency in a virtual training environment.
