[0049] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0050] In order to optimize the building information model and make it more standardized and normative, a process optimization method for the building information model is provided in the technical solution of the present application. The following is an explanation of a process optimization method for the building information model provided in the embodiment of the present application in combination with multiple specific examples. Figure 1 A schematic diagram of a process optimization method for a building information model provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the process optimization method includes:

[0051] S101, obtaining a building information model to be optimized.

[0052] The building information model to be optimized is the data result of the building information generated during the design stage or the construction stage of the original engineering project, and is also the optimization object of the process optimization method provided in the embodiment of the present application.

[0053] Optionally, the building information model to be optimized can be designed and constructed by a modeling platform, wherein the modeling platform includes but is not limited to Autodesk, ArchiCAD and Vectorworks.

[0054] S102, according to the preset component standards, check each component item of the building information model to be optimized and obtain component qualification information.

[0055] Components are the basic elements that make up the building information model and are also the most basic elements that carry geometric information and attribute information. In the modeling platform, components are components of a single building logic or a collection of multiple building components. Checking the component items of the building information model can also be said to be an inspection of the basic element units that constitute the building information model.

[0056] Checking the components of the building information model according to the preset component standards is the basic inspection work of the building information model. It mainly checks whether the contents of each component in the building information model meet the uniformity, consistency of the drawing model and project requirements.

[0057] After checking each component item of the building information model, the component qualification information is obtained. The component qualification information refers to whether the component is qualified. Since there are different majors in the engineering project, such as building structure major, electromechanical major, etc., the building information models of the corresponding majors contain different component categories. Therefore, different qualification standards should be set for different majors to meet the relevant requirements of national standards and industry standards. Optionally, in the embodiment of the present application, according to the different majors in the engineering project, the majors of the inspection content are mainly divided into: building structure major, electromechanical major and other majors. For example, the score of the building structure professional component is not less than 0.8, the score of the electromechanical professional component is not less than 0.6, and the score of other professional components is not less than 0.7, otherwise the component project qualification information is unqualified, that is, the building information model is deemed to be unpassed, and the components of the building information model need to be optimized.

[0058] S103, if the component qualification information indicates qualification, check the compliance items of the building information model to be optimized according to the preset compliance standards to obtain compliance qualification information; the compliance items include at least one of the following: basic setting items, integrity items, and modeling normative items.

[0059] After each component item of the building information model is checked and qualified, the compliance of the building information model is further checked. The compliance check is the basic judgment condition for the overall compliance of the building information model. In the embodiment of the present application, optionally, the compliance items of the compliance check include three items: basic setting items, integrity items, and modeling normative items. The inspection order of the three compliance items is not limited. For example, the inspection order can be: basic setting items -> integrity items -> modeling normative items. The inspection of the three compliance items can also be carried out in parallel.

[0060] The inspection of each compliance item can be divided into main control items and general items. The difference is that the lower limits of the qualification standards are set separately. Optionally, in an embodiment of the present application, the score of any main control item should reach 1, and the score of the general item should not be lower than 0.7, otherwise the qualified information of the compliance item is unqualified, that is, the building information model is deemed to have failed, and the compliance items of the building information model need to be optimized.

[0061] Optionally, during the inspection process of the compliance items, if the inspection method shows that it is implemented in accordance with the project requirements, if the project has specific requirements, the inspection is carried out in accordance with the project requirements; if the project has no relevant requirements, this inspection item can be skipped.

[0062] S104: If the compliance information indicates compliance, check the consistency items of the building information model to be optimized according to a preset consistency standard to obtain consistency information.

[0063] After all compliance items of the building information model have been checked and met the standards, the consistency of the building information model will be checked. The consistency items mainly check whether the three-dimensional shape of the building information model meets the requirements of the engineering stage, whether the plan, elevation and section views correspond to the two-dimensional design drawings, and whether the parameters of the building information model are consistent with the parameters in the two-dimensional design drawings.

[0064] The consistency check of the building information model combines the building information model with the specific actual situation of the engineering project, providing convenient and efficient data results for the engineering project, namely the building information model.

[0065] According to the different types of consistency items, different qualification standards need to be set for each type of consistency item, so the lower limits of the qualification standards are set separately. If the consistency item is judged as unqualified, that is, the building information model is considered to be unqualified, and the consistency item of the building information model needs to be optimized.

[0066] S105: Outputting an optimized building information model according to the component qualification information, the compliance qualification information, and the consistency qualification information.

[0067] The building information model checks each component item through the preset component standard to obtain qualified information, checks each compliance item through the preset compliance standard to obtain compliance qualified information, checks each consistency item through the preset consistency standard to obtain consistency qualified information, and if all three qualified information are qualified, the optimized building information model is output.

[0068] In summary, the process optimization method of a building information model provided by the present application performs three checks on the building information model to be optimized: component inspection, model compliance inspection, and model consistency inspection. If the building information model is judged to be unqualified, the building information model is optimized accordingly according to the unqualified inspection items, and then the optimized building information model is inspected to finally obtain a qualified optimized building information model. The process optimization method takes into account a variety of factors. Compared with the current supervision policies and inspection standards, the inspection items of the building information model are more comprehensive and detailed. When the process optimization method is used to inspect and optimize the building information model, according to each qualified information, the specific problems of the unqualified inspection items can be optimized in a targeted manner, which can improve the standardization and normativeness of the building information model. In addition, the process of the process optimization method is complete, has good versatility for different engineering projects, can be flexibly used for different engineering projects, in the process of optimizing the building information model, the process optimization method can be expanded to compile different inspection standards, and at the same time, the inspection standards can be further improved by raising the threshold of the qualified standards to improve the technical quality of the building information model.

[0069] In the above Figure 1 Based on the process optimization method of a building information model shown, an embodiment of the present application also provides a method for implementing a building information model that outputs an optimized building information model based on qualified information, compliant qualified information, and consistent qualified information in the process optimization method of the above-mentioned building information model.

[0070] In this embodiment, if any one or more of the component qualified information, the compliance qualified information, and the consistency qualified information are unqualified, the corresponding parameters in the building information model are adjusted until the component qualified information, the compliance qualified information, and the consistency qualified information are all qualified, and the optimized building information model is output. This embodiment is specifically explained in conjunction with the accompanying drawings as follows. Figure 2 A schematic diagram of another process optimization method for building information modeling provided in an embodiment of the present application. Figure 2 As shown above Figure 1 The method shown may include:

[0071] S201, obtaining a building information model to be optimized.

[0072] For the specific implementation and effect description of S201, see the above Figure 1S101 in the description will not be described in detail here.

[0073] S202: According to the preset component standards, check each component item of the building information model to be optimized to obtain component qualification information.

[0074] For the specific implementation and effect description of S202, see the above Figure 1 S102 in the description will not be repeated here.

[0075] S203, judging whether the component is qualified.

[0076] After obtaining the scores of each sub-item in each component item, the scores of each sub-item in each component item of each profession are compared with the preset component qualification standards of each profession according to the scores of each sub-item in each component item and the preset component qualification standards of each profession. If the scores are lower than the preset component qualification standards, the corresponding construction item is judged to be unqualified, and the component of the building information model is unqualified, and the process returns to S201, optimizes the components, and then re-obtains the building information model and checks it; otherwise, the components of the building information model are judged to be qualified, and the process goes to S204.

[0077] S204, checking compliance items of the building information model to be optimized according to preset compliance standards to obtain compliance qualification information; the compliance items include at least one of the following: basic setting items, integrity items, and modeling normative items.

[0078] The specific implementation and effect description of S204 refer to the above Figure 1 S103 in the description will not be repeated here.

[0079] S205, judging whether the model compliance is qualified.

[0080] After the components of the building information model are qualified, the scores of each sub-item in the compliance items of the building information model are obtained. According to the scores of each sub-item and the preset compliance qualification standards, the scores of each sub-item in the main control project and the general project are compared with the preset compliance standards of the main control project and the general project. If they are lower than the preset compliance qualification standards, the corresponding compliance items are judged to be unqualified, and the compliance of the building information model is unqualified. The process returns to S201, and the parameters corresponding to the compliance items of the building information model are adjusted, and then the building information model is obtained again and checked; otherwise, the building information model is judged to be compliant and qualified, and the process goes to S206.

[0081] S206: Check the consistency items of the building information model to be optimized according to the preset consistency standard to obtain consistency qualification information.

[0082] The specific implementation and effect description of S206 refer to the above Figure 1 S104 in the description will not be described in detail here.

[0083] S207, judging whether the model consistency is qualified.

[0084] After the building information model is qualified in compliance, the score of each sub-item in the consistency item of the building information model is obtained. According to the score of each sub-item and the preset consistency qualification standard, the score of each sub-item of each type of consistency item is compared with the preset consistency qualification standard of each type of consistency item. If it is lower than the preset consistency qualification standard, the corresponding consistency item is judged to be unqualified, and the consistency of the building information model is unqualified. Return to S201, adjust the parameters of the consistency item of the building information model, and then re-acquire and check the building information model; otherwise, judge that the consistency of the building information model is qualified, and enter S208.

[0085] S208: Outputting an optimized building information model according to the component qualification information, the compliance qualification information, and the consistency qualification information.

[0086] The specific implementation and effect description of S208 refer to the above Figure 1 S105 in the description will not be described in detail here.

[0087] In this embodiment, the component inspection, model compliance inspection, and model consistency inspection in the process optimization method of the building information model are in a progressive relationship. The model compliance inspection can only be performed after the component inspection is completed and judged to be qualified, and the model consistency inspection can only be performed after the model compliance inspection is completed and judged to be qualified. From component inspection to model inspection, inspection is carried out from the inside out to ensure the depth, comprehensiveness, and efficiency of the inspection.

[0088] Optionally, the relationship between component check, model compliance check and model consistency check includes but is not limited to a progressive relationship; it can be a parallel relationship, such as component check, model compliance check and model consistency check are performed simultaneously, and three qualified information are obtained at the same time. If at least one qualified information is unqualified, the building information model is unqualified, and relevant parameters are adjusted to continue optimization; otherwise, the building information model is qualified and the optimized building information model is output; it can also be an unordered relationship, such as first performing a model compliance check, and after the compliance is qualified, a model consistency check is performed, and after the model consistency is qualified, a component check is finally performed, and after the component is qualified, the optimized building information model is output.

[0089] In this embodiment, when the component check, model compliance check or model consistency check fails, after optimization, the process returns to S201 to re-acquire and check the building information model. The method in this embodiment is only an example. Optionally, when the model compliance check fails, after optimization, the process can directly enter S204 to re-check the model compliance without re-checking the components that have already passed the inspection. Similarly, when the model consistency check fails, after optimization, the process can directly enter S206 to re-check the model consistency without re-checking the components and compliance checks that have already passed the inspection.

[0090] In the above Figure 1 Based on the process optimization method of a building information model shown in the figure, the embodiment of the present application also provides a method for implementing the acquisition of component qualification information in the above method. In this embodiment, for example, the component qualification information can be determined according to the qualification information corresponding to each component project. The embodiment is specifically explained in conjunction with the accompanying drawings as follows. Figure 3 A schematic diagram of a process flow for obtaining component qualification information in a process optimization method of a building information model provided in an embodiment of the present application. Figure 3 As shown, in the above method S102, according to the preset component standard, each component item of the building information model to be optimized is checked to obtain component qualification information, including:

[0091] S301, according to the preset component standard, check each component item of the building information model to be optimized, and obtain the qualified information corresponding to each component item.

[0092] The component items of the building information model include at least one of the following: component naming, component material, component creation, component geometric expression accuracy, and component attribute information accuracy.

[0093] Among them, the preset standard for component naming is: the entire project adopts a unified naming logic system, such as the naming rule of "floor-component name-drawing corresponding component name-size".

[0094] The inspection method for component materials is: the selection of component materials should be in line with the actual situation and cannot be divorced from real life.

[0095] The preset standards for component creation are: extract the detailed list, the corresponding material category should be expressed by a unified family category, the detailed list is extracted from the overall building information model, including all components, component attribute information, component connection information, component material category and other information related to the building information model; components should have a standardized and unified family category; similar components should use a unified creation and naming logic.

[0096] The preset standards for the accuracy of component geometric expression are: the geometric dimensions of the components should be consistent with the two-dimensional construction drawing design drawings / as-built drawings, and the component geometric modeling accuracy should comply with the project requirements.

[0097] The method for checking the accuracy of component attribute information is as follows: the component attribute information should be consistent with the two-dimensional construction drawing design / completion drawing and design parameters, and the accuracy of the component attribute information should comply with the project regulations. Among them, the component attribute information includes the color and hardness of the component.

[0098] According to the inspection methods of component naming, component material, component creation, component geometric expression accuracy, and component attribute information accuracy, the scores corresponding to each sub-item in each component project are calculated to determine the qualified information of each component project.

[0099] Optionally, the first sub-item of component creation is: extracting a detailed list, the corresponding material category should be expressed using a unified family category, the detailed list is extracted from the overall building information model, including all components, component attribute information, component connection information, component material categories and other information related to the building information model, assuming that the corresponding score of the building structure major is 0.8, the second sub-item is: components should have a standardized unified family category, assuming that the corresponding score of the building structure major is 0.85, the third sub-item is: similar components should use a unified creation and naming logic, assuming that the corresponding score of the building structure major is 0.9, further, the judgment condition for obtaining qualified components of the building structure major based on preset data is that the score should not be lower than the preset value, for example 0.8.

[0100] On the above basis, all sub-items of component creation of building structure specialty are qualified, that is, the qualified information of component creation of building structure specialty is qualified. If there is at least one sub-item of component creation of building structure specialty whose score is lower than the preset component qualified standard, the qualified information of component creation of building structure specialty is unqualified.

[0101] Optionally, the components can be spot-checked to obtain scores, such as spot-checking 20% ​​of the total number of components. For example, the inspection method for the naming of the model components is to adopt a unified naming logic system for the entire project. If there is one component whose name does not conform to the naming logic, then 0.01 is subtracted from the full score of 1, and the score of the model component naming is 0.99, which is higher than the preset component qualification standard of 0.8, and the model component naming inspection item is qualified; if there are 21 components whose names do not conform to the naming logic, then 0.21 is subtracted from the full score of 1, and the score of the model component naming is 0.79, which is lower than the preset component qualification standard of 0.8, and the model component naming inspection item is unqualified, and the qualified information of the component inspection is unqualified.

[0102] S302, determining component qualification information according to the qualification information corresponding to each component item.

[0103] If the qualification information of all component items is qualified, the component qualification information is qualified; if the qualification information of at least one component item is unqualified, the component qualification information is unqualified.

[0104] In the above Figure 1 Based on the process optimization method of a building information model shown in the figure, the embodiment of the present application also provides a method for implementing the above method to obtain compliance and qualified information. In this embodiment, for example, the qualified information of each compliance item can be obtained according to the score corresponding to each sub-item in each compliance item, and then the compliance and qualified information can be determined. The embodiment is specifically explained in conjunction with the accompanying drawings as follows. Figure 4 A schematic diagram of a process flow for obtaining compliance information in a process optimization method of a building information model provided in an embodiment of the present application. Figure 4 As shown, in the above method S103, if the component qualification information indicates that the component is qualified, the compliance items of the building information model are checked respectively according to the preset compliance standard to obtain the compliance qualification information, including:

[0105] S401, obtaining the qualified information of each type of sub-item in each compliance item according to the preset compliance standard.

[0106] Compliance items include at least one of the following: basic setting items, integrity items, and modeling normative items.

[0107] Among them, the basic setting project mainly checks whether the foundation of the overall building information model meets the requirements, such as the splitting and coordination mechanism of the building information model of large-scale engineering projects, the benchmark points and coordinates linked after splitting, and the overall attribute information of the project, to determine whether the basic settings are met at the beginning of the establishment of the building information model.

[0108] The main control items of the basic setting project include: model splitting logic, collaborative working mechanism, coordinate system setting, and model linking.

[0109] The preset standard of the model splitting logic is: the building information model should be split according to the project division section, specialty, floor, etc., and the model splitting rules of all relevant parties should be consistent. A large project will be split into multiple project division sections and assigned to multiple teams for construction. The splitting rules of the building information model should be consistent with the splitting rules in the actual construction process, including but not limited to the project division section, specialty, floor, etc.

[0110] The preset standards of the collaborative working mechanism are: different models should work together according to the linking rules. For example, escalators and handrails are different models, and they should work together according to the linking rules to ensure that the escalator and handrails operate together. Different disciplines in the same model should work together according to the work set rules. For example, escalators can complete their normal operation through the collaborative work of structural and electrical disciplines.

[0111] The preset standard for coordinate system setting is: the coordinate system and elevation system, that is, the three-dimensional coordinate system, should be adopted according to the requirements of the project to ensure that the building information model is a three-dimensional graphic.

[0112] The preset standards for model linking are: Building Information Models should be divided and linked together according to regional and professional classifications. A larger engineering project will be divided into multiple engineering sections and assigned to multiple teams for construction. Finally, the results of multiple teams should be linked together, and the model linking rules should be consistent with the linking rules during the construction process; the Building Information Model should be consistent with the position of the general line map of this project in the true north state, and the project north should be adjusted according to the convenience of drawing the Building Information Model. When establishing the Building Information Model according to the design drawings, the Building Information Model should be designed as a square or rectangle. The top of the established Building Information Model is not necessarily the direction of north in the actual construction process. Therefore, it is necessary to adjust the direction of the Building Information Model to make it consistent with the direction of the actual construction process; if different disciplines create building information models separately, the building structure discipline should create a "starting model", and the cooperating discipline should use the "starting model" as a reference for the linked model through shared coordinates. The cooperating discipline should add the building information model of its own discipline to the "starting model" without changing the framework of the "starting model".

[0113] General items of basic setting items include: model deduction rules, model material naming and appearance, and model project parameters.

[0114] The preset standard of the model deduction rule is: the building information model deduction should comply with the investment supervision quantity calculation principle.

[0116] The preset standards for the project parameters of the model are: relevant project parameters should be added in accordance with the requirements of the project, shared parameters should be used for adding, project parameters should be unified, and shared parameters should be used when adding or modifying, so that the same project parameters in the building information model can be added or modified uniformly to ensure the consistency of project parameters; there should be no redundant project parameter setting items; check whether the parameter information entered in the building information model meets the requirements of national or industry standards.

[0117] The integrity project mainly checks the integrity of the building information model, whether the internal non-geometric elements and model storage and display meet the requirements, such as key items such as axis grid, view, elevation, and general items such as model non-geometric information, electronic folder type settings, etc., whether they meet the integrity requirements.

[0118] The main control items of the integrity project include: the model's axis grid and plan view, the model's elevation, and the model's component elements.

[0119] Among them, the preset standards for the axis grid and plane view of the model are: in the main plane view, check the axis grid according to the design drawing requirements, there should be no omissions and it should be displayed correctly; check other plane views, the axis grid should be displayed correctly. Check the axis grid according to the design requirements of the design drawings, adjust the building information model to the view of the corresponding orientation according to the view in the drawing, such as the main view, top view and left view, and then check the axis grid in the design drawing with the axis grid in the building information model.

[0120] The preset standard for the model's elevation is: check the integrity of all spaces and areas in the construction drawing design included in the elevation, check whether the elevation of the main framework of the entire building information model is complete, and whether the elevation of the design space is complete; check the elevation in the main elevation section view, that is, check whether the elevation inside the building information model is complete.

Due to the existence of auxiliary lines, if the main components are replaced by lines, the single view will be inconvenient for browsing and viewing.

[0122] General items of integrity projects include: setting up project folders, model views, and entering model information.

[0123] Among them, the preset standard for setting up project folders is: project folders should be set up according to type, and the setting rules should comply with the relevant regulations of the engineering project.

[0124] The preset standard for the model's view is: the view settings in the building information model should meet the actual needs and display requirements of the project.

[0125] The preset standards for model information entry are: model information entry of the building information model should comply with the regulations of the project, and the attribute information should be comprehensive, including but not limited to material, size, etc.

[0126] The modeling standardization project mainly checks whether the relevant documents of the building information model comply with the specifications or project requirements, whether the association between internal geometric elements and non-geometric elements and the classification of elements meet the requirements, such as the main control project of the association between components and elevations, as well as model naming, classification of categories and types, and whether general items such as redundancy and repetition meet the modeling standardization requirements.

For example, when adjusting the elevation of the first layer, the components of the first layer should be linked with the adjustment of the elevation of the first layer, while the components of the second layer should not be linked with the adjustment of the elevation of the first layer.

[0129] General items of modeling standardization projects include: naming rules for modeling, equipment categories of models, family types, model redundancy checks, model overlaps or component duplications.

[0130] The preset standards for modeling naming rules are: project folder naming rules should comply with the regulations of the engineering project; building information model file naming rules should comply with the regulations of the engineering project; work set naming rules should comply with the regulations of the engineering project.

[0131] The preset standard for the equipment category of the model is: equipment components with obvious categories should be classified as follows: electrical devices and electrical equipment used in electrical engineering, mechanical equipment used in HVAC and water supply and drainage, etc.; except for the combination of embedded components which can be conventional models, the number of other conventional models should not be too large, less than 10%. Too many other conventional models will affect the browsing and viewing of the building information model.

[0132] The preset standard for family types is: the family in the building information model contains different specifications and types of similar components, and different parameter information combinations constitute the corresponding family type; the family type is compared with the design specification table, and there should be no missing items.

Model overlap and component duplication can be checked through the modeling platform.

[0135] According to the inspection methods of basic setting items, integrity items, and modeling normative items, the qualified information of each first-category sub-item in each compliance item is obtained. Optionally, the first-category sub-item of each compliance item also includes a second-category sub-item. First, the score of each second-category sub-item in each first-category sub-item of each compliance item is obtained, and the obtained score is compared with the preset qualified standard. If it is lower than the preset qualified standard, the second-category sub-item is unqualified, and the qualified information of the corresponding first-category sub-item is unqualified.

[0136] Optionally, 20% of the number of models are randomly checked. The inspection method of the collaborative work mechanism includes two items: different models should work together according to the linking rules, and different disciplines of the same model should work together according to the working set rules. If there are no two models that do not work together according to the linking rules, the score obtained is 1, which is equal to the preset qualification standard 1 of the main control project, and it is qualified. At the same time, if there are 30 models between different disciplines that do not work together according to the working set rules, then 0.3 is subtracted from the full score of 1, and the score obtained is 0.7, which is lower than the qualification standard of the main control project, and it is unqualified. Then, the qualified information of the collaborative work mechanism of a sub-project of the basic setting project is unqualified.

[0137] S402, obtaining the qualified information of each compliance item according to the qualified information of each first-class sub-item.

[0138] If the qualified information of all the first-category sub-items of each compliance item is qualified, then the qualified information of the compliance item is qualified; if the qualified information of at least one first-category sub-item in the compliance item is unqualified, then the qualified information of the compliance item is unqualified.

[0139] S403, obtaining compliance qualification information according to the qualification information of each compliance item.

[0140] If the qualified information of all compliance items is qualified, the compliance qualified information is qualified; if the qualified information of at least one compliance item is unqualified, the compliance qualified information is unqualified.

[0141] In the above Figure 1Based on the process optimization method of a building information model shown, the embodiment of the present application also provides a method for implementing the above method to obtain consistency qualified information. Optionally, in the above method S104, the consistency items of the building information model to be optimized are checked according to the preset consistency standard to obtain consistency qualified information, wherein the consistency items are mainly divided into two categories: consistency items in the design stage and consistency items in the construction stage.

[0142] The consistency items in the design phase include: the three-dimensional shape reflected by the model and the expression of the two-dimensional design drawings, and the accuracy of the design model information.

[0143] Among them, the preset standards for the three-dimensional shape reflected by the model and the expression of the two-dimensional design drawings are: the plan, elevation and section drawings generated by the building information model correspond to the two-dimensional drawings in the design stage, and the views should maintain position consistency; the shape logic of the building information model must be built according to the design logic and meet the design construction requirements.

[0144] The scores of the two inspection items of the three-dimensional shape reflected by the model and the expression of the two-dimensional design drawings are obtained, and the average value is calculated to obtain the qualified information of the three-dimensional shape reflected by the model and the expression of the two-dimensional design drawings in the design stage.

[0145] The preset standard for the accuracy of the design model information is: the accuracy of the building information model information and the project parameter settings should meet the design requirements, comply with the design regulations, and be consistent with the design drawings, design parameters, and design specifications. Qualified information on the accuracy of the design model information is obtained according to the preset standard.

[0146] Consistency items during the construction phase include: the three-dimensional shape reflected by the model and the expression of the two-dimensional completion drawings, and the accuracy of the model information during construction.

[0147] Among them, the preset standards for the three-dimensional shape reflected by the model and the expression of the two-dimensional completion drawings are: the plan, elevation and section views generated by the building information model correspond to the drawings, and the views should maintain position consistency; the dimensions should be consistent with the two-dimensional completion drawings; the shape logic of the building information model must be built according to the construction logic and meet the actual construction requirements.

[0148] The scores of the three inspection items in the three-dimensional shape reflected by the model and the two-dimensional completion drawing expression are obtained, and the average value is calculated to obtain the qualified information of the three-dimensional shape reflected by the model and the two-dimensional completion drawing expression during the construction stage.

[0149] The preset standard for the accuracy of the model information of the construction is: the accuracy of the building information model information and the project parameter settings meet the needs of the engineering construction and take into account the needs of the operation and maintenance stage, comply with the construction regulations, and are consistent with the drawings, designs, construction parameters, actual related information of facilities and equipment, and acceptance specifications. According to the preset standards, qualified information on the accuracy of the model information of the construction is obtained.

[0150] For example, the qualification standard is: the score of the three-dimensional shape reflected by the model and the expression of the two-dimensional design drawings and the score of the three-dimensional shape reflected by the model and the expression of the two-dimensional completion drawings are not less than 0.8, and the score of the model information accuracy in the design stage and the model information accuracy in the construction stage are not less than 0.7. In the design stage, it is judged whether the three-dimensional shape reflected by the model and the expression of the two-dimensional design drawings and the model information accuracy of the design are all qualified. If they are all qualified, the consistency of the building information model in the design stage is qualified. In the construction stage, it is judged whether the three-dimensional shape reflected by the model and the expression of the two-dimensional completion drawings and the model information accuracy of the construction are all qualified. If they are all qualified, the consistency of the building information model in the construction stage is qualified.

[0151] If the scores of the two sub-items of the three-dimensional shape reflected by the model and the expression of the two-dimensional design drawings meet the qualified standards, the three-dimensional shape reflected by the model and the expression of the two-dimensional design drawings are qualified. If the score of at least one sub-item does not meet the qualified standards, the three-dimensional shape reflected by the model and the expression of the two-dimensional design drawings are unqualified, and then the consistency of the building information model in the design stage is unqualified. If the scores of the three sub-items of the three-dimensional shape reflected by the model and the expression of the two-dimensional completion drawings meet the qualified standards, the three-dimensional shape reflected by the model and the expression of the two-dimensional completion drawings are qualified, otherwise they are unqualified, and then the consistency of the building information model in the construction stage is unqualified.

[0152] Optionally, 20% of the number of models is randomly checked. The method for checking the accuracy of model information in the design stage is that the accuracy of model information and project parameter settings should meet the design requirements, comply with the design regulations, and should be consistent with the drawings, design parameters, and design specifications. If there are 35 project parameters that are inconsistent with the drawing parameters, then 0.35 is subtracted from the full score of 1, and the score of model information accuracy in the design stage is 0.65, which is lower than the preset qualified standard of model information accuracy in the design stage of 0.7. The model information accuracy in the design stage is unqualified, and then the consistency of the building information model in the design stage is unqualified.

[0153] The embodiment of the present application combines the three-dimensional shape of the building information model with the actual situation of the project, checks whether the building information model meets the requirements of the engineering stage, and provides convenient and efficient data results for the engineering project.
