[0001] The present invention belongs to the technical field of engineering quality supervision, and in particular relates to a quality inspection and evaluation method and system based on BIM. Background Art

[0002] Since the establishment of the engineering quality supervision agency, the methods of training and improving the supervision capabilities of engineering quality supervisors have mainly relied on self-study by quality supervisors, pre-job training, various standard lectures, quality supervision theoretical knowledge examinations, and steering inspections and evaluations.

[0003] The model is a data carrier that carries construction information (attributes / parameters), a digital entity that is operated and processed by software, and a full-life BIM application that a project must achieve from design to construction and operation and maintenance. Traditional construction methods and inspection and evaluation methods are unlikely to meet the owner's audit requirements, and it is also difficult to achieve refined management of the process. Summary of the invention

[0007] S2. Establish a construction breakdown structure and associate it with the constructed BIM model;

[0008] S3, construct according to the associated data;

[0009] S4. Obtain quality inspection information based on changes in the associated data during the formwork construction process.

[0010] Furthermore, the step S1 is specifically as follows:

[0011] S11, entering the component information required for BIM modeling into the corresponding component information summary table to generate a component database;

[0012] S12, perform BIM modeling based on the information in the component database;

[0013] S13. Convert the established BIM model into three dimensions and upload it to the database.

[0014] Furthermore, in the framework information summary table in step S11, detailed information, design attributes, construction attributes and cost attributes of components are stored with component codes as indexes;

[0015] The detailed information of the component includes component type, family name, modeling method, deepening method and accuracy requirement;

[0016] The design attributes are component attributes added by the model designer;

[0017] The construction attributes are component attributes added in the detailed model;

[0018] The cost attributes are the component attributes required in quantity calculation and pricing.

[0019] Furthermore, the step S2 is specifically as follows:

[0022] S23. Extract component information from the database through the interface, and associate it with the process, indicator, form and flow information in the construction breakdown structure to complete the association between the construction breakdown structure and the BIM model.

[0023] Furthermore, the process library in step S21 is used to store all processes in the construction project;

[0027] The construction decomposition structure in step S22 is: the detailed, refined, hierarchical and structured construction process is decomposed into a construction PBS structure tree, and the entire construction process is stored in the form of a tree structure;

[0028] In step S23, after the construction breakdown structure is associated with the BIM model, the completion status of each construction process will be reflected in the corresponding component.

[0029] Furthermore, the step S4 is specifically as follows:

[0030] During the construction process according to the form, each construction process is represented by configuring and filling in the form content of the engineering type file, and when there is a need for quality inspection and evaluation, the form content that needs to be inspected and evaluated is exported to complete the quality inspection and evaluation;

[0031] Among them, the quality inspection form content includes basic form information, filling content and review information;

[0032] The basic information of the form includes the information of the construction unit, the date of filling in the form and the tools used; the filling content includes the measurement point value and uploaded pictures, and the review information includes the reviewer, review opinion and time of each node.

[0039] Furthermore, the method for the construction decomposition module to decompose the construction project is specifically as follows:

[0040] Establish a process library, indicator library, form library and flow library, and based on them, decompose the construction process into a construction PBS structure tree in a detailed, refined, hierarchical and structured manner, and store the entire construction process in the form of a tree structure.

[0041] Furthermore, the form type filled in the form configuration module is a system template form or a custom form;

[0049] The specific implementation modes of the present invention are described below so that those skilled in the art can understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific implementation modes. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations utilizing the concept of the present invention are protected.

[0050] Embodiment 1:

[0051] like Figure 1 As shown, a method for obtaining quality inspection and evaluation information based on a BIM model includes the following steps:

[0052] S1. Build the BIM model and upload it to the database;

[0053] S2. Establish a construction breakdown structure and associate it with the constructed BIM model;

[0054] S3, construct according to the associated data;

[0055] S4. Based on the changes of the associated data during the mold construction process, the corresponding quality inspection and evaluation information is obtained.

[0056] Step S1 in this embodiment is specifically as follows:

[0057] S11, entering the component information required for BIM modeling into the corresponding component information summary table to generate a component database;

[0058] S12, perform BIM modeling based on the information in the component database;

[0059] S13. Convert the established BIM model into three dimensions and upload it to the database.

[0060] Specifically, in the framework information summary table in step S11, detailed information, design attributes, construction attributes and cost attributes of components are stored with component codes as indexes;

[0061] The detailed information of the component includes component type, family name, modeling method, deepening method and accuracy requirement;

[0062] The design attributes are component attributes added by the model designer;

[0063] The construction attributes are component attributes added in the detailed model;

[0064] The cost attributes are the component attributes required in quantity calculation and pricing.

[0065] The model types for the 3D conversion in step 13 are generally Revit and Bentley, and after conversion they are in a unified format that can be recognized by the system.

[0066] Step S2 in this embodiment is specifically as follows:

[0067] S21. Establish a process library, indicator library, form library and flow library, and enter data into them;

[0068] S22, retrieve data from the process library, indicator library, form library and flow library to establish a construction breakdown structure;

[0069] S23. Extract component information from the database through the interface, and associate it with the process, indicator, form and flow information in the construction breakdown structure to complete the association between the construction breakdown structure and the BIM model.

[0070] Specifically, the process library in step S21 is used to store all processes in the construction project, such as construction projects, municipal projects, field road projects in airport projects, etc.

[0071] The indicator library is used to store professional indicators corresponding to all processes in the process library, including state-type indicators and numerical indicators. Among them, state-type indicators do not need to be reflected by specific numerical values, but are only indicator types reflected by text descriptions or pictures, while numerical indicators need to be expressed by specific numbers.

[0072] The form library is used to store forms of engineering type files, including form files, table files, and notice files, etc.;

[0073] The process library is used to store the approval and acceptance processes of procedures and forms, and can be customized or apply templates in the system.

[0074] The construction breakdown structure in step S22 is: Figure 2 As shown, the detailed, refined, hierarchical and structured construction process is decomposed into a construction PBS structure tree, and the entire construction process is stored in the form of a tree structure;

[0075] In step S23, after the construction breakdown structure is associated with the BIM model, the completion status of each construction process will be reflected in the corresponding component, for example, the construction status of each stage will be fed back in different component colors.

[0076] Step S4 of this embodiment is specifically as follows:

[0077] During the construction process according to the form, each construction process is represented by configuring and filling in the form content of the engineering type file, and when there is a quality inspection and evaluation requirement, the form content that needs to be inspected and evaluated is exported to obtain the quality inspection and evaluation information;

[0078] Among them, the quality inspection form content includes basic form information, filling content and review information;

[0079] The basic information of the form includes the information of the construction unit, the date of filling in the form and the attributes such as the tools used; the filling content includes the measurement point value and uploaded pictures, and the review information includes the reviewer, review opinion and time of each node.

[0080] The above-mentioned construction according to the form means that the technical personnel will lightweight the three-dimensional model. After uploading it to the platform, the user will associate the model components with the form. According to different construction processes, the associated forms under the components are also different. The construction unit will then carry out construction based on the design information in the model, and the component completion progress will be completely matched with the form.

[0081] Embodiment 2:

[0082] The embodiment of the present invention provides a quality inspection information acquisition system based on the quality inspection information acquisition method in the first embodiment, including:

[0083] BIM model building module, used to build the required BIM model according to the model components;

[0084] Construction decomposition module, used to decompose the construction process;

[0085] Data association module, used to associate each component in the BIM model with each process in the decomposed construction process;

[0086] The form configuration module is used to configure and fill in the corresponding form to reflect the progress of the project according to the completion status of the construction process;

[0087] The quality inspection and evaluation module is used to export the form corresponding to the construction project when quality inspection and evaluation is required to obtain quality inspection and evaluation information.

[0088] The method for decomposing the construction project by the above-mentioned construction decomposition module is specifically as follows:

[0089] Establish a process library, indicator library, form library and flow library, and based on them, decompose the construction process into a construction PBS structure tree in a detailed, refined, hierarchical and structured manner, and store the entire construction process in the form of a tree structure.

[0090] The form type filled in the above form configuration module is a system template form or a custom form;

[0091] All form versions generated during the entire life cycle of form filling in the form configuration module are retained.

[0092] Specifically, for form configuration, users can customize form types according to actual needs; form attributes can be configured according to actual reporting needs, and for different construction standards, the reporting fields can be flexibly configured. For form approval process templates, users can customize the drawing process template or select existing system templates. The form configuration process in the embodiment of the present invention is flexible, adapting to the rapid configuration of massive forms in multiple professions, adapting to the situation of constantly changing forms and different standards across the country, and has strong promotion capabilities.

[0093] During the form filling process, after the user customizes the form configuration, the system automatically arranges and generates a form style that meets the national standards based on the form type and attribute fields set by the user, and has two styles: WEB and APP. During the entire life cycle of the form filling, multiple form versions may be generated due to re-filling and data supplementation due to the content not meeting the acceptance requirements. The system completely retains each version to achieve full process traceability. After the form is filled, the system will automatically integrate the basic information of the form (construction unit information, filling date, tools used, etc.), filling content (measurement point values, uploaded pictures), and review information (reviewers, review opinions, time, etc. of each node) according to the system's built-in form style library, and can export PDF forms.

[0094] The above-mentioned quality inspection and evaluation module includes all the contents in the system. One of the important tasks is to complete the inspection and evaluation work through process-driven by filling in the measured point values ​​of each single indicator in the forms under each process and uploading hidden project pictures. Once the inspection and evaluation of all forms under each process is completed, each process can be completed, and the inspection and evaluation of the entire project can be completed by feedback from top to bottom.
