Abstract
Current 4D simulation only uses the main structure of a construction project as demonstration content, meaning that integration with the surrounding environment is lacking. Moreover, the solution reached may not necessarily be the optimal one. Therefore, if the factor of the surrounding environment can be considered in the discussion process, the efficiency of 4D simulation can be enhanced. To address this problem, this study integrated BIM and augmented reality (AR) technologies. The surrounding environment was incorporated into the structure model, and 4D simulation was performed on the construction environment. By using BIM and the Unity game development engine, augmented reality (AR) systems were constructed to enable the integration of real-world environments with smart devices.
