[0002] BIM (Building Information Modeling) technology is a digital tool used in engineering design, construction, and management. By integrating digital and information models of buildings, it is shared and transmitted throughout the entire life cycle of project planning, operation, and maintenance. It enables engineering and technical personnel to correctly understand and efficiently respond to various building information, provides a basis for collaborative work for design teams and all construction entities including construction and operation units, and plays an important role in improving production efficiency, saving costs, and shortening construction periods.

[0003] In traditional building monitoring, monitoring personnel basically use simple methods, such as visual inspection, rebound method, pulse echo method, and ray method. These methods monitor the structure periodically, but these methods have obvious defects, such as poor integrity, which only monitors part of the structure; poor safety, manual monitoring is required, and manual monitoring cannot be performed in dangerous places. Once the staff is in a dangerous place for monitoring, it is easy to be in danger of life; poor real-time performance, it takes time to integrate the data after monitoring, and then we can know the construction status or progress, and it cannot be monitored in real time, and the efficiency is extremely low. With the development of society and the advancement of science and technology, the safety of construction in the field of construction is still an urgent problem to be solved for the optimization and improvement of construction quality supervision.
