Processing, sorting, distribution, retrieval and storage of construction engineering information. The processing of data and information by engineering supervision should start with identification. Distribution and retrieval of information. Information retrieval needs to be based on a certain hierarchical management system. The basic principle of information publishing and retrieval is that departments and personnel who need information have the right to obtain the information they need at the first time. 3. Storage of information. Storing information requires the establishment of a unified database. According to the actual situation of construction projects, it is necessary to standardize the organization of data files. All parties involved in the project should coordinate and unify data storage methods, standardize data file names and establish a unified coding system. Store data in the form of network database as much as possible, reduce data redundancy, ensure data uniqueness and realize data sharing.
