BIM is an innovative technology in the AEC industry, providing a digital representation of building projects. Yet, the ever-changing environment of construction projects requires efficient methods for detecting changes within the BIM system. Detecting changes requires the identification and assessment of modifications that take place during the project's progression, guaranteeing precision, uniformity, and effective teamwork among project participants. Identifying changes in BIM models is essential for preserving project integrity, minimizing mistakes, and automating the process saves time, thereby enhancing project timelines. Conventional methods for identifying changes, like visual inspections or manual surveys, are frequently time-consuming and susceptible to human error. Consequently, there is an increasing need for automated change detection techniques that improve the process and boost efficiency in the AEC industry. This paves the way for delving into the importance of change detection in BIM and emphasizes the necessity for creative frameworks to tackle this issue. This thesis aims to create a framework for automated BIM model[1]ling with family creation along with a BIM-based framework for indoor building com[1]parison analysis. The inputs are the BIM Models, which are to be analysed, and the outcome of the study is the detailed representation of the element changes between the models. The proposed method has been tested on different datasets, and the results depict the effectiveness of the proposed method in detecting model changes.     «
