As an important part of engineering quality assurance, quality inspection data must be guaranteed to be authentic. Quality inspection data must truly and realistically reflect the actual situation on the spot, and cannot be made out of nothing, exaggerated, or recorded less. Quality inspection data must be resolutely put an end to forgery. Many times, because the information is not timely, the construction unit directly falsifies the quality inspection information when necessary, which leads to the untrue quality inspection information. This situation must be resolutely prohibited. Quality inspection data is not only an important embodiment of quality management, but also an important basis for measurement, and also a reference for later project implementation such as maintenance, management and transformation. Therefore, the quality inspection data must be true and reliable.

Systematization of data

In municipal engineering construction, quality inspection data are closely linked from start to completion. From the first working procedure of construction to the completion of the project, information expression is closely linked. In the presentation of data, there can be no omission of processes, no repetition of processes and no inversion. Quality inspection data is the basis of reflecting the physical objects on site, and it must be rigorous and complete. The quality inspection data shall be consistent with the relevant design and specifications, and shall not exceed the requirements of the design and specifications.

Filing of quality inspection data

According to the requirements of Archives Law, Specification for Archiving and Arrangement of Construction Engineering Documents and Regulations on Technical Management of Archiving of Construction Engineering Documents in Sichuan Province, the construction engineering materials shall be archived according to certain principles and methods, and the materials with preservation value shall be compiled into a book and handed over to local archives management institutions according to relevant regulations. Archives are precious wealth with high historical value. The construction project file is the original record of the project construction process, and it is an important basis for identifying the quality of the project, especially the quality of the concealed project in the structural engineering. At the same time, the construction project files record the construction technology, quality and other related data, which is equivalent to the patient's admission to the hospital. Generally speaking, if the local urban construction archives have no special requirements, the municipal engineering data should be sorted and bound in accordance with the relevant provisions in the Code for the Management of Construction Engineering Archives. It is clearly pointed out in the "Management Specification for Construction Project Archives" that the construction project archives filled in by all contractors should be based on the construction and acceptance specifications, engineering contracts, design documents and unified standards for engineering construction quality acceptance; Engineering files should be collected and sorted in time with the progress of the project, and classified by specialty, carefully written, legible, complete, accurate and true, without any remaining matters. Forms should be unified, and forms that need to be added according to special requirements should be unified; Engineering archives should be managed at different levels. The technical director of the municipal engineering contractor is responsible for organizing the whole process of auditing the project files of the unit, and the file manager of the relevant unit is responsible for the collection and arrangement of the project files. Those who alter, forge, borrow at will, damage or lose engineering files will be punished according to relevant regulations. If the circumstances are serious, legal responsibility shall be investigated according to law. Therefore, the collation of quality inspection data must be strict, serious and serious. When compiling data, you should use a signature pen or pen to write. Ballpoint pens are strictly prohibited, and the pages must be A4 white paper. Requirements for composing papers in data archiving: the arrangement of data in engineering data volumes should be arranged according to the internal relationship of data and the sequence of data formation time; When there are both text materials and patterns in the volume, the text materials are in front and the pattern materials are behind; As-built drawings are arranged once according to the same professional drawing number; When the newly drawn as-built drawing is attached to the original drawing, it is required that the newly drawn as-built drawing is in the front and the original drawing is in the back; Arrangement of each file: file cover → directory (volume) → file → preparation form → back cover (white paper); Specification of case file: A4 size should be used for documents, covers, catalogues and reference tables in the volume, and A4 white paper should be used as a foil for documents smaller than A4 size; The file should not be too thick, generally not more than 40mm.

Importance of municipal engineering quality inspection data

Importance of municipal engineering quality inspection data: quality inspection data is one of the data that must be sorted and filed in the project completion file directory. Article 17 of the Regulations on Quality Management of Construction Projects issued by the State Council stipulates: "The construction unit shall, in strict accordance with the relevant state regulations on file management, timely collect and sort out documents and materials in all aspects of construction projects, establish and improve the construction project files, and hand over the construction project files to the construction administrative department or other relevant departments in time after the construction project is completed." During the construction of the south extension line of Hongxing Road, the requirements for quality inspection materials are very strict. In view of the importance of quality inspection data in engineering survey, it is required to be timely, complete, true and systematic. At the same time of site construction, the quality inspection data must be followed closely and signed by the supervisor, the owner and the geological prospecting designers in time for confirmation. In the process of measurement, copies of the corresponding quality inspection data must be attached to the measurement sheet as the measurement basis, and the signatures of all data must be perfect, and the signatures in the same column must use the same font. Multiple handwriting is absolutely not allowed in the same column. Quality inspection data is an important record of municipal engineering construction and an important document basis of engineering management. Real and scientific engineering data can provide a good foundation for the future maintenance, expansion and management of the project. The Ministry of Housing and Urban-Rural Development and local construction authorities attach great importance to the management of engineering data, and have repeatedly pointed out clearly that any project that does not meet the standards is judged as unqualified and has veto power over the quality of the project. After the handover of municipal construction, after long-term use, roads will inevitably have various problems, which require maintenance management, such as dealing with concrete cracks and improving the bearing capacity of pavement. Consult the construction materials during maintenance, and select similar materials for maintenance according to its construction standards to ensure that it is consistent with that before maintenance, otherwise it will destroy its beauty; The same is true for pipelines. When the city is expanded or rebuilt, it is necessary to install new pipelines and connect them with the original pipelines. At this time, in order to ensure that the original pipeline is not damaged, it is necessary to consult the information to understand the diameter, material, installation height and coverage thickness of the pipeline. Engineering quality inspection data is also the reference for municipal engineering projects such as new construction and reconstruction; At the same time, the quality inspection data of municipal engineering is also one of the important contents of project completion acceptance. The construction process of municipal engineering is the process of municipal engineering construction and quality acceptance, which shows the importance of municipal engineering quality inspection data in practical engineering.

Municipal engineering is related to the image and future development of the city, so the requirements for its construction are very strict. As an important part of the quality assurance system, quality inspection data must be treated strictly, timely, complete, true and systematic. The management and integration of engineering quality inspection data should run through the whole municipal engineering construction activities, that is, from the start of the project to the completion and acceptance of the project. Project participants must deeply understand the importance of municipal engineering quality testing data and do a good job in sorting, managing and protecting the data. Because of the indecomposability of building products, data control must be regarded as a means of quality control, and it must be clear that managing engineering data is as important as building a good project.
