Interactive modeller for equipment operation in long-span bridge construction

Three dimensional (3D) animation of construction simulation makes communication among different project participants effective by visualizing the construction operation. The effect of 3D animation becomes stronger in a more complex operation. However, the modelling process of the 3D animation requires time-consuming efforts. Thus, interactive modelling environment is strongly preferred where equipment, materials, and temporary structures can easily and freely be placed by the construction engineers in a real-time manner. This research aims to develop an equipment operation modeller that can allow users to interactively communicate with the system for long-span bridges. Augmented reality is used as the main methodology for implementing the modeller. The proposed modeller is expected to significantly improve the planning process of construction equipment operations.
