[0002] Construction information management refers to the process of widely applying information technology and developing information resources among all parties involved in construction project management and at all stages to promote the continuous improvement of construction project management level. Construction project informatization has the characteristics of automated information collection, electronic information storage, networked information exchange, information retrieval tools and scientific information utilization.

[0003] The existing publication number is CN119005944A, which discloses an information-based maintenance and management platform for ancient buildings. The platform includes an ancient building detection module, a data feedback module, a threshold prediction module, and an ancient building traceability module. The information detection unit detects the age of the ancient building and data on corrosion caused by external environmental pollution, and then compares the data with the predicted score of the ancient building calculated by the ancient building damage prediction unit to determine whether the ancient building is damaged. If damaged, an alarm with different signals is generated based on the damage difference. At the same time, the data analysis unit infers aging data of the ancient building that has not yet been corroded by external environmental pollution based on the age of the ancient building detected by the information detection unit, modifies the predicted threshold of the year calculated by the ancient building damage prediction unit, and then formulates a maintenance plan for the ancient building based on the changes in the building damage data.
