A Conceptual Framework for Construction Safety Training using Dynamic Virtual Reality Games and Digital Twins

The construction industry is suffering from a high rate of accidents that significantly affect the overall performance of projects. Compared to the conventional safety training methods, Virtual Reality (VR) games offer a more immersive and interactive learning experience for the participants. However, training scenarios in most of the existing VR games lack complex tasks and the realistic environment required for actual construction. This work proposes a conceptual framework for dynamically updating VR training games through information streaming from the digital twins. The training scenarios in VR games are automatically created from the project intent information, project status knowledge, safety regulations, and historical knowledge provided by the digital twins. Therefore, construction workers can be trained in realistic training environments with relevant tasks they soon afterwards pursue. Dynamic VR training is expected mutually beneficial for enhanced digital twins and periodic construction safety management. Inadequate technology readiness level of the construction industry and difficulty in collecting good quality data are some of the major challenges for implementing this framework
