After retrieving the second interview report, it will be classified and summarized in the Examination Record Registration Form in time for easy searching. 5. In the construction stage, the supervisor sends a letter to inspect the safety production situation on the construction site, and informs the construction unit in writing of all kinds of safety accidents found, urging them to make immediate rectification; If the situation is serious, the project shutdown order shall be issued in time, requiring the construction unit to stop work for rectification and report to the construction unit at the same time. After the hidden dangers of safety accidents are eliminated, the rectification results should be checked and the opinions of review or return to work should be signed. If the construction unit refuses to make rectification or stops work for rectification, it shall report to the competent department of construction or industry where the project is located in a timely manner. Telephone report, there must be a call record, timely supplementary written report. Inspection, rectification, review and report shall be recorded in the supervision log and supervision monthly report. 6. The compilation and arrangement of supervision diary supervision data is an important part of supervision work and the embodiment of supervision service workload and value. The record of supervision diary is an important part of supervision data, the most authentic work evidence in the process of project implementation, and the embodiment of the recorder's quality, ability and technical level. Therefore, the contents of the supervision diary must be true and comprehensive, and fully reflect the degree of performance of the contract by all parties to the construction. It is an important duty of supervision to record the daily engineering situation fairly. (1) Record the time accurately. When meteorological supervisors write supervision diaries, they often only pay attention to time records and ignore meteorological records. In fact, the accuracy of meteorological records is directly related to the quality of the project. (1) The variation values of concrete strength and mortar strength are obviously different at different temperatures. Supervisors can accurately calculate the theoretical calculation value of strength according to the temperature during concrete pouring and the temperature change in the next few days, so as to judge whether they have the conditions for formwork removal, whether they have the bearing capacity and how big the bearing capacity is. ② During the construction of sub-projects such as foundation and foundation works, main works, decoration works and roofing works, the change of weather directly affects the construction quality of the projects. Some projects have a series of quality problems after the end of the unit project. Investigators can analyze them according to the supervision diary of the problem parts, and some quality problems may be directly related to meteorology. For example, during construction in rainy season, the foundation trench is soaked by rain, which causes the change of soil quality and then affects the quality of foundation engineering. (2) Conduct on-site inspection and record the problems related to the project truly, accurately and comprehensively. (1) Before writing the supervision diary, supervisors must conduct on-site inspection, increase the number of inspections and improve the inspection quality. After the inspection, it should be sorted according to different majors and different construction sites, and finally the supervision diary should be written neatly and signed by the recorder. (2) When making supervision diary records, supervisors often only record the progress of the project, but not the problems existing in the construction, or think that the problems are so small that it is unnecessary to write them in the diary; Or think that the problem has been solved and there is no need to make trouble again. In fact, this ignores the embodiment of its own value. At present, many owners don't understand the role of supervision in engineering projects. If we don't record the problems found by supervision and supervision work in our daily data, how can we let the owners know more about the work content and service purpose of supervision? Therefore, when recording the supervision diary, all problems related to the project (including three controls, three pipes and one coordination) should be truly, accurately and comprehensively reflected. (3) Care about safe and civilized construction management and make safety inspection records. Most general supervision contracts do not contain safety content. Although safety inspection belongs to the service outside the contract, it directly affects the mood of the operators. And then affect the quality of the project, so supervisors should pay more attention and remind more. Make inspection records to ensure the normal development of supervision work. (4) the handwriting is neat, the terminology is standardized, and the content is rigorous. Project supervision fully demonstrates the daily expression of various activities, problems and their related impacts by the recorder. Improper handling of words, such as many typos, obvious alterations, unreasonable sentences, illogical words, improper words, irregular use of daily sayings, etc. , will have adverse consequences. Supervisors with insufficient language skills should be familiar with drawings and specifications in their daily work, improve their technical quality, accumulate experience, master the essentials of writing and carefully record supervision diaries.
