Description

Technical Field

[0001] This application relates to the field of engineering construction management technology, specifically to a BIM-based engineering supervision method, device, equipment, product, and medium. Background Technology

[0002] With the rapid development of smart cities and digital construction, BIM (Building Information Modeling) technology has become a core carrier for the approval of engineering construction projects. Especially in city-level BIM-based approval and permitting scenarios, it uses three-dimensional digital models to carry multi-dimensional information such as design, construction, and operation and maintenance, providing visualized and precise technical support for administrative approvals. Currently, the core technical aspects of BIM-based approval and permitting mainly include: standardized storage of BIM model files, multi-format parsing, and intelligent rule review. Various competent authorities rely on these technologies to automate the verification of project compliance.

[0003] In related technologies, BIM application for different approval stages (such as planning permits, construction permits, and completion acceptance) is carried out independently by the corresponding competent authorities: each competent authority collects the BIM model files for its own stage (such as the scheme model for the planning stage, the detailed model for the construction stage, and the actual model for the completion stage), and conducts project-level engineering approval of the BIM files in a specific format based on the current approval requirements.

[0004] Under this technical system, the BIM application process is relatively independent from the regulatory approval process, leading to a disconnect between business data and the geometric or attribute information of the BIM model. This makes it difficult to achieve cross-stage data consistency verification and collaborative analysis. Furthermore, BIM data at each stage only provides management services for the current stage, which can easily lead to data transmission gaps and consequently, inconsistencies in approval conclusions across stages (such as discrepancies between the approved floor area ratio and the actual completed building area), affecting the reliability of approval results and regulatory efficiency.

[0005] Therefore, there is an urgent need for an integrated management technology solution that can connect master data across stages and achieve deep integration of BIM models and business operations, so as to improve approval efficiency, reduce management costs and ensure regulatory consistency. Summary of the Invention

[0006] This application provides a BIM-based engineering supervision method, device, equipment, product, and medium, which can achieve deep integration, cross-stage transfer, and consistency verification of multi-stage BIM models and business approval data, thereby improving the quality and efficiency of construction project supervision.

[0010] Optionally, based on the approval assistance results and the review results of the previous regulatory stage, the review results of the current regulatory stage are obtained, including: If there is no benchmark indicator in the review results of the previous regulatory stage that corresponds to the indicator data of the current regulatory stage, the review results of the current regulatory stage are obtained based on the indicator data and the approval assistance results. If a benchmark indicator exists in the review results of the previous regulatory phase that corresponds to the indicator data of the current regulatory phase, the indicator difference between the indicator data and the benchmark indicator is determined, and the review result of the current regulatory phase is obtained based on the indicator difference and the approval auxiliary results.

[0011] Optionally, the method further includes: If there are benchmark indicators corresponding to the indicator data of the current regulatory stage in multiple regulatory stages prior to the current regulatory stage, then the indicator differences between the indicator data and the benchmark indicators of each regulatory stage shall be determined respectively. Based on the differences in the aforementioned indicators and the approval assistance results, the review results for the current regulatory stage are obtained.

[0012] Optionally, based on the simplified model, the required indicator data for the approval scenario are determined, including: For attribute-type indicators, the attribute information of the target component is extracted from the simplified model as the indicator data; For rule-based indicators, the indicator data is obtained by calculating the indicator data based on the geometric and attribute information of the target component in the simplified model using a preset calculation formula. All the aforementioned indicator data are aggregated to obtain the indicator data required for the approval scenario.

[0018] Thus, by deeply integrating BIM models with business data and establishing cross-stage data transfer mechanisms, the pain points of traditional construction project supervision, such as data fragmentation, inefficient review, and conflicting approvals, are resolved.

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the existing technology, BIM application for different approval stages (such as planning permit, construction permit, and completion acceptance) is carried out independently by the corresponding competent authorities: each competent authority collects the BIM model files for its own stage (such as the scheme model for the planning stage, the detailed model for the construction stage, and the actual model for the completion stage), and conducts project-level engineering approval for BIM files in specific formats based on the current approval requirements.

[0023] Under this technical system, the BIM application process is relatively independent from the regulatory approval process, leading to a disconnect between business data and the geometric or attribute information of the BIM model. This makes it difficult to achieve cross-stage data consistency verification and collaborative analysis. Furthermore, BIM data at each stage only provides management services for the current stage, which can easily lead to data transmission gaps and consequently, inconsistencies in approval conclusions across stages (such as discrepancies between the approved floor area ratio and the actual completed building area), affecting the reliability of approval results and regulatory efficiency.

[0024] In view of this, this application provides a BIM-based engineering supervision method to solve the problems of data disconnect, transmission gaps and approval conflicts in the existing technology.

[0025] For details, please refer to Figure 1 The specific process of this BIM-based engineering supervision method can be as follows: S110. Obtain BIM models and project information for each regulatory stage.

[0026] In this embodiment, the regulatory stage refers to the key management nodes in the approval process of a construction project. Each stage corresponds to specific approval items and regulatory priorities, and the competent authorities review the project's compliance in accordance with their statutory responsibilities.

[0027] For example, in chronological order, the regulatory stages include: 1. Planning permit stage, which mainly reviews whether the overall layout, land use, and building scale (such as plot ratio and building density) of the project comply with the overall urban plan; 2. Construction permit stage, which mainly verifies the details of the construction drawings (such as structural safety and material standards), construction organization plan, and qualifications of participating units; 3. Completion and acceptance stage, which mainly verifies whether the actual construction results of the project (such as building area, greening rate, and supporting facilities) are consistent with the approval requirements, and confirms that the project is ready for delivery and use after approval.

[0028] A BIM model is a virtual model that expresses the physical and functional characteristics of a construction project in three-dimensional digital form. It includes the geometric shape, spatial relationship and attribute information of components and serves as a visual carrier of project information.

[0029] For example, the BIM model in the planning permit stage is a 3D model that includes the overall building outline, site area, building layout, and floor area ratio, mainly used to express the macro layout of the project. The BIM model in the construction permit stage is a 3D model that is detailed down to structural components (beams, columns, floor slabs), MEP (mechanical and electrical pipelines) (water pipes, electrical wiring routes), and decoration details, including detailed attributes such as material types and dimensional parameters.

[0030] Project information is non-geometric business data related to construction projects, including basic project attributes, applicant information, approval requirements, and external constraints, which is used to supplement the management dimensions of the BIM model.

[0031] For example, project information includes: project name (e.g., "XX Residential Community"), land use number (e.g., "SZ-2025-001"), construction unit (e.g., "A Real Estate Company"), project address; application items (e.g., "Construction Permit Application"), approval basis (e.g., "Urban Residential Area Planning and Design Standards"), land area (40,000 square meters), planned plot ratio requirement (≤2.5); application time, contact person information, and special project requirements (e.g., green building star rating standards).

[0032] It should be noted that the format or rules of the BIM models in each regulatory stage in this application must be backward compatible, so that the BIM model in the current regulatory stage can be obtained by supplementing and deepening the data foundation of the BIM model in the previous regulatory stage, thus avoiding modeling from scratch or data gaps in each stage.

[0033] Specifically, the process mainly includes: S110-1. During the planning phase, the BIM model is split into individual units, and each unit is assigned a unique code to obtain multiple BIM units.

[0034] First, according to the planning approval requirements, the BIM model is broken down into individual units. For example, the BIM model of a large complex is divided into multiple BIM units according to function, such as "Building 1 (Residential)," "Building 2 (Commercial)," and "Building 3 (Underground Parking)," and each BIM unit is assigned a unique code. For example, the code for "Building 1 (Residential)" is BLD-001, the code for "Building 2 (Commercial)" is BLD-002, and the code for "Building 3 (Underground Parking)" is BLD-003. The applicant (construction unit) needs to fill in the relevant project information (such as purpose and number of floors) based on these unit definitions. Then, the regulatory department (planning bureau) reviews and confirms the unit information, for example, "BLD-001 is for residential use, with 20 floors above ground." S110-2. For each regulatory stage after the planning stage, based on the model deepening requirements and application information of the current regulatory stage, the BIM individual buildings of the previous regulatory stage are modeled and information is supplemented to obtain the BIM model and project information of the current regulatory stage.

[0035] In subsequent regulatory phases following the planning phase, such as the construction permit phase, the completion and acceptance phase, and the operation and maintenance management phase, the applicant can directly reuse the individual information from the previous regulatory phase and supplement it with new data for the current regulatory phase.

[0036] Specifically, based on the current application requirements (such as detailed construction drawings and material testing reports), new information (such as structural reinforcement ratio and environmental protection level of decoration materials) can be submitted in the application system and linked with the BIM unit code of the previous stage (such as the planning stage).

[0037] For example, during the construction permit stage, it is necessary to refine structural components (beams, columns, floor slabs), mechanical and electrical pipelines (water pipes, electrical wiring routes), and finishing details (wall materials, door and window specifications). During the completion and acceptance stage, it is necessary to supplement the parameters of the components actually completed (such as concrete strength grade, actual pipeline routing), and equipment installation information (such as elevator models, fire sprinkler head locations). The relevant application information can be collected through the application system and integrated with the individual unit information from the previous supervision stage to obtain the project information for the current supervision stage. At the same time, the BIM individual units can be refined using professional software (such as Tekla Structures) to obtain the BIM model for the current supervision stage, and the project information can be associated with the BIM model based on the BIM individual unit code.

[0038] Subsequent regulatory authorities can use BIM unit coding to verify more detailed information, such as comparing whether the "number of residential floors" in the construction drawings is consistent with the "20 floors" in the planning stage, so as to achieve cross-stage data transfer.

[0039] This embodiment uses the unique BIM unit code to split and manage the model, realizing full-cycle data association from planning to operation and maintenance.

[0040] Please refer to Figure 2 , Figure 2 This is a flowchart illustrating the process of single-unit splitting and application in an embodiment of this application. For example... Figure 2As shown, the process begins with defining individual units during the project's planning and permitting phase. This clarifies the individual components of the project and assigns each defined unit a unique code. Next, a unified classification standard is set and applied throughout the entire construction cycle to ensure consistency in the definition and processing of units across different stages, preventing confusion and errors. Then, the unit data from the construction permit, construction, and completion phases is compared with the unified classification results. If issues are found during the comparison (i.e., the comparison fails), a "unit splitting and merging" operation is required. Units are processed according to certain rules, including: 1. Subspace division according to regulations: Based on relevant building codes and design requirements, units are re-split or merged according to subspace division standards. 2. Automated unit identification and correction: Automated technologies are used to identify and correct errors in units, ensuring they conform to the unified classification standards. 3. Manual identification and processing: When automated methods cannot fully resolve issues, manual identification and analysis are used to adjust and process units to achieve the correct classification. If the individual data at each stage conforms to the unified classification standard, that is, after comparison and inspection, it enters the "individual data service" stage, where the sorted and confirmed individual data is provided in a usable form for use in subsequent operation and maintenance stages.

[0041] During the operation and maintenance phase, a many-to-many mapping relationship is established between individual building data and grid office building codes, and each building is assigned a code. Simultaneously, the association between building codes and individual buildings is circulated back to match and update the building codes with the corresponding individual building information, ensuring data accuracy and consistency and providing accurate association information for subsequent operation and maintenance phases. Ultimately, by establishing a relationship between individual building data and grid office building codes, resources are better integrated during the operation and maintenance phase, enabling effective management and maintenance of individual buildings.

[0042] S120. Integrate project information with the BIM model to obtain BIM master data. The BIM master data includes geometric information, attribute information, and business data of model components.

[0043] In this embodiment, BIM master data is a structured data set formed by deeply integrating the geometric and attribute information of the BIM model with project information. It includes the geometric feature information, physical attribute information and associated business approval data of the model components, and is the core data foundation for approval and management.

[0044] Among them, the geometric information of model components, namely geometric feature information, refers to the quantitative description of the spatial shape, position and topological relationship of a single component (such as wall, beam and column) in the BIM model, which is used to define the physical form and spatial layout of the component.

[0045] For example, the geometric information of a load-bearing wall in a building includes: a cuboid shape (5m long × 0.2m wide × 3m high), its coordinate position in three-dimensional space (X=10m, Y=20m, Z=0m to 3m), and its connection relationship with adjacent beams and columns.

[0046] The attribute information of model components refers to metadata that describes the physical properties, material parameters, functional uses and technical indicators of BIM model components, and is used to define the non-geometric features and performance requirements of components.

[0047] For example, the attribute information of concrete beam components includes: concrete strength grade (C30), reinforcement ratio (2.8%), cross-sectional dimensions (width 300mm × height 600mm), and seismic resistance level (Level II); the attribute information of green lawn components includes: vegetation type (Ipomoea purpurea), coverage rate (95%), irrigation requirements (twice a week), and maintenance cycle (four times a year).

[0048] Business data refers to management information directly related to the construction project approval process, including project application information, approval conclusions, indicator requirements, and process status data, which are used to support regulatory decisions and compliance verification.

[0049] For example, the project application information includes: the "proposed building height" (50m), "parking space ratio" (1:1.2), and "energy-saving design standard" (GB 50189-2015) submitted by the construction unit. The approved data includes: the "gross floor area" (80,000㎡) verified during the planning supervision stage, the "structural safety level" (Level 1) confirmed during the construction permit stage, and the "actual green space ratio" (32%) recorded during the completion acceptance stage. The process status data includes: the current supervision stage (construction permit stage), the application time (2025-03-15), and the approval progress (accepted / under review / approved).

[0050] In this embodiment, by integrating the geometric and attribute information (such as component dimensions and material parameters) of the BIM model with project information (such as land area and approval requirements) to generate BIM master data, the barrier of "separation of model and business data" in traditional approval is broken, providing a complete data foundation for subsequent approval processes. For example, when approving "floor area ratio" during the planning and supervision stage, the actual land area and building area data of the building in the BIM master data can be directly linked, realizing one-stop processing of "indicator calculation - compliance review - business approval" and avoiding the inefficiency and errors of manually verifying multi-source data.

[0051] Based on this, BIM master data and BIM models are stored according to the Building Information Modeling (BIM) data storage standard for easy retrieval later.

[0052] For example, please refer to Figure 3 , Figure 3 This is a schematic diagram illustrating the process of data storage and management in an embodiment of this application. For example... Figure 3 As shown, for different formats of Building Information Modeling (BIM) or related engineering data files, such as RVT (a model file format generated by Revit software), AC (a file format related to AutoCAD software), and 3ds (a file format of 3ds Max software), the process first involves parsing the files, extracting key information, and converting them according to BIM data storage standards and specifications to ensure they can be recognized and processed by subsequent workflows. Next, the converted data undergoes a self-check and is stored in the database. The self-check includes aspects such as data completeness, accuracy, and consistency, ensuring that the data quality meets requirements before proceeding to the next step.

[0053] Then, related data from different sources are integrated to provide a more comprehensive and accurate information view. This includes: data fusion within the same project phase (such as design or construction phases) to make the data more complete and coherent; multi-disciplinary data fusion to combine data from architecture, structure, HVAC, plumbing, electrical, and other disciplines, breaking down data barriers between disciplines and enabling data collaboration and sharing; and individual building data splitting or merging. For projects consisting of multiple individual buildings, the overall multi-building data can be split to facilitate the management and analysis of individual buildings; alternatively, data from multiple individual buildings can be merged to obtain the overall project data.

[0054] After data fusion and other processing are completed, the data undergoes further review through an online system. This includes checking data compliance and conformity with project requirements to ensure the data meets the standards and specifications for subsequent use. Furthermore, the reviewed data is processed according to specific business needs and application scenarios. For example, data format conversion, data extraction, and data analysis are performed to generate more valuable information or meet the data input requirements of specific systems.

[0055] Finally, the processed, multi-dimensional data (including spatial, temporal, and professional dimensions) covering the entire project scope is comprehensively managed to provide a data foundation for subsequent data retrieval services, simplified model extraction, and on-demand data extraction. Simultaneously, relevant data generated from actual business applications (such as IoT data, detailed models or drawings of facilities and equipment, and equipment maintenance records) are fed back into the data management system to further enrich and improve the existing stored data, providing a more comprehensive basis for subsequent decision support and project management.

[0056] S130. Calculate indicators and conduct compliance reviews of the BIM master data in the current regulatory phase to obtain auxiliary approval results.

[0057] In this embodiment, the approval assistance result is auxiliary decision-making information generated based on the BIM master data at the current regulatory stage through indicator calculation and compliance review. It includes quantitative indicator data and qualitative compliance conclusions, and is used to provide the competent authority with a basis for review.

[0058] For example, the indicator data includes: "floor slab load bearing capacity" (2.1kN / ㎡), "structural reinforcement ratio" (2.6%), and "green space ratio" (35%) calculated during the construction phase; the compliance conclusions include: "the reinforcement ratio of 2.6% meets the standard requirements (≥2.5%)", "the green space ratio of 35% meets the standard (planning requirement ≥30%)", and "the floor slab load is close to the limit (design value is 2.2kN / ㎡), and a review is recommended".

[0059] In this embodiment, the BIM master data includes multiple BIM buildings and their corresponding building data. The BIM master data at the current regulatory stage is used for indicator calculation and compliance review to obtain approval support results, including: S130-1. Determine the approval scenario at the current regulatory stage.

[0060] In this embodiment, based on the specific regulatory stage of the project and the current approval items (such as structural safety review, green space ratio verification, and fire lane verification), the core business scenarios that need to be reviewed are identified. These approval scenarios are the targets for subsequent data screening, indicator calculation, and compliance review.

[0061] For example, if a residential project enters the construction permit stage and the current approval item is "whether the area of ​​the central green space in the community complies with the plan", then the approval scenario is "green space ratio verification".

[0062] S130-2. From the multiple BIM individual units in the current regulatory stage of BIM master data, select the target individual unit that is related to the approval scenario.

[0063] Among them, a BIM unit is the smallest management unit of a construction project. When determining the target unit, it is necessary to combine the functional attributes of the unit (such as residential, commercial, and green space) and the business logic of the approval scenario (such as structural review only related to building units, and green space verification only related to green space units) to narrow the scope of data processing, focus on key units, reduce interference from irrelevant components, and improve the pertinence of subsequent indicator calculations.

[0064] For example, when the approval scenario is "green space ratio verification", then green functional units such as "central green belt of the community" and "green space between buildings" are selected as target units, while non-green units such as residential buildings and underground garages are ignored.

[0065] S130-3. Extract target components and attribute information related to the approval scenario from the target unit and the unit data corresponding to the target unit, and generate a simplified model.

[0066] In this embodiment, by further extracting target components (such as beams, columns, and foundations of structural units, and lawns and shrubs of green units) and their key attribute information (such as reinforcement ratio, cross-sectional dimensions, and green area) directly related to the approval scenario from the geometric model and unit data of the target unit, irrelevant components and attributes are eliminated to generate a simplified model containing only the necessary information of the scenario, namely the MVD sub-model (Model View Definition sub-model).

[0067] For example, when the approval scenario is "green space ratio verification", the geometric information of the green area is extracted from the "central green belt of the community" unit - area: 5000 With the attribute information—vegetation type: lawn, coverage: 95%—a simplified model containing only the green area can be generated.

[0068] S130-4. Based on a simplified model, determine the indicator data required for the approval scenario.

[0069] In this embodiment, the types of indicators are first determined, including attribute-based indicators and rule-based indicators. Attribute-based indicators refer to indicators that can be directly obtained through simple attributes, such as the "design fire resistance rating" and "planned use category" of a component. Rule-based indicators refer to indicators that need to be calculated through rules, such as the "reinforcement ratio of beam components" and "floor slab bearing capacity".

[0070] For attribute-based indicators, the attribute information of the target component is extracted from the simplified model as indicator data; for rule-based indicators, the indicator data is obtained by calculating the indicator based on the geometric and attribute information of the target component in the simplified model using a preset calculation formula; all indicator data are summarized to obtain the indicator data required for the approval scenario.

[0071] For indicators obtained through attribute extraction, the corresponding attribute field values ​​can be accurately located and extracted directly from the parsed component attribute information. For example, the direct attribute values ​​such as "building function category" and "design service life" marked in the component attributes can be extracted; for the marked quantitative attributes (such as "story height = 3.0m" and "plot ratio = 2.5"), their values ​​can be directly obtained as the indicator results.

[0072] For indicators that require rule-based calculation, the indicator calculation rule library corresponding to the approval scenario is invoked. The geometric parameters (such as area, volume, and length) and attribute parameters (such as strength, density, and reinforcement ratio) parsed in the above steps are substituted into the calculation formula to generate indicator data. For example, the "green space ratio" is calculated as: total green area / total project land area × 100%.

[0073] Finally, all the individual indicator results obtained through rule calculation and attribute extraction are summarized to form a complete set of indicator data corresponding to the current approval scenario.

[0074] S130-5. Compare the indicator data with the preset standards and norms to identify violations and risk points, and obtain approval assistance results.

[0075] Specifically, the compliance review engine can compare the calculated indicator data with preset standards and regulations (such as national / local building codes and benchmark values ​​for project approval) to automatically identify non-compliant items and risk points in the target BIM unit. For example, a unit may have a reinforcement ratio lower than the minimum specified value or a green space ratio that does not meet planning requirements. The engine then generates an approval auxiliary result that includes specific indicator data for the target unit, location information of non-compliant components, and the approval conclusion. Thus, intelligent indicator review improves approval efficiency and accuracy.

[0076] S140. Based on the approval auxiliary results and the review results of the previous regulatory stage, the review results of the current regulatory stage are obtained.

[0077] In this embodiment, the review result is a final review judgment generated by comparing and analyzing the approval auxiliary results of the current regulatory stage with the approval conclusions (e.g., indicator data) of the previous regulatory stage. This judgment is used to confirm the compliance of the data in the current stage and its consistency with historical approvals.

[0078] For example, if the "gross floor area" approved in the previous stage (planning permit stage) was 80,000 square meters... The "actual building area" calculated during the current regulatory phase (construction permit phase) is 81,000 square meters. The review result is: "The building area exceeds the planned area by 0.1 square meters". (Difference rate 1.25%), within the allowable fluctuation range ( If the current regulatory stage calculates the "structural reinforcement ratio" to be 2.3% (lower than the standard requirement of 2.5%), the review result will be: "The reinforcement ratio does not meet the standard and needs to be rectified to ≥2.5%".

[0079] Specifically, based on the approval support results and the review results of the previous regulatory stage, the review results of the current regulatory stage are obtained, including: If no benchmark indicator corresponding to the indicator data of the current regulatory stage exists in the review results of the previous regulatory stage, the review result of the current regulatory stage is obtained based on the indicator data and approval auxiliary results. If a benchmark indicator corresponding to the indicator data of the current regulatory stage exists in the review results of the previous regulatory stage, the indicator difference between the indicator data and the benchmark indicator is determined, and the review result of the current regulatory stage is obtained based on the indicator difference and approval auxiliary results. If benchmark indicators corresponding to the indicator data of the current regulatory stage exist in multiple regulatory stages prior to the current regulatory stage, the indicator difference between the indicator data and the benchmark indicator of each regulatory stage is determined respectively; the review result of the current regulatory stage is obtained based on the indicator difference and approval auxiliary results.

[0080] In this process, the indicator data for each regulatory phase is linked to a single BIM model unit. If the "indicator data" for the current regulatory phase cannot find a directly corresponding "benchmark indicator" in the review results of the previous regulatory phase (e.g., the previous phase did not generate a benchmark for this type of indicator, or the two are not directly related in the business rules), then the original data of the current regulatory phase and the supporting materials or rules used during the approval process are used to analyze and derive the review conclusion for this round. If a directly corresponding "benchmark indicator" can be found in the review results of the previous regulatory phase, then the differences between the two are compared, such as numerical differences, compliance differences, progress differences, etc., and then the indicator differences are analyzed together with the supporting information or rules used during the approval process to finally derive the review result for the current regulatory phase.

[0081] In addition, if corresponding benchmark indicators can be found in more than one review result of the previous regulatory stage (for example, the business needs to trace the benchmarks of multiple historical stages for comprehensive judgment), then the difference between the current indicator data and the benchmark indicators of each regulatory stage should be calculated and marked. Then, the differences of several historical stages should be combined for comprehensive analysis to finally obtain the review result of the current regulatory stage.

[0082] For example, in the planning permit stage: assuming the "gross floor area" of "BLD-001 (Building 1)" is automatically calculated to be 80,000 square meters using the BIM model. (Based on the total area of ​​all floors ≤24 meters in the model), and this indicator is approved. This data is stored in the BIM building master data as a "benchmark indicator of the previous regulatory stage". Construction permit stage: Assuming that after the construction unit submits the detailed model, the platform automatically extracts the gross floor area of ​​"BLD-001", and the calculated result is 80,500 square meters. (Due to the increased balcony projection area after the construction drawings were refined). Therefore, the current regulatory stage (construction permit stage) differs from the previous regulatory stage (planning permit stage) in that there is an "80,000" [area / area]. The difference between the benchmark indicators is: "The gross floor area for this phase is 80,500 square meters". This is an increase of 0.05 million compared to the planning stage. The final review result was: compliant, due to adjustments made to the rules regarding balcony area calculation. The master data was then updated, and both phases of the record were retained.

[0083] This embodiment stores the review results and approval auxiliary data at each stage, enabling the inheritance and comparison of indicators across the "planning, construction, and completion" stages. This facilitates cross-stage data transfer and consistency verification, ensuring the continuity of the approval process. In application, if a discrepancy is found between historical approval conclusions and current data (e.g., a planned green space ratio of 30% and a completed green space ratio of 25%), the problematic stage can be quickly located and the cause traced, significantly reducing the risk of approval discrepancies.

[0084] S150. Link the review results of the current regulatory phase with the BIM master data to obtain the BIM theme library for the current regulatory phase.

[0085] In this embodiment, the BIM subject library is a composite data set stored according to the regulatory stage. It includes the review results, approval assistance results and related BIM master data of the current regulatory stage. It is a "data archive" of the stage approval conclusions and supports cross-stage data transmission and regulatory traceability.

[0086] For example, the BIM subject library at the planning permit stage includes: storing "building area of ​​80,000 square meters". The BIM library for the construction permit stage includes data such as "plot ratio 2.3" and "building functional layout approved," and links these data to the master model (including the overall building outline and land area). The library also stores data such as "floor slab load capacity 2.1kN / Data such as “structural reinforcement ratio 2.6%” and “construction drawing approval” are used, and the data is linked to the detailed construction drawing model (including structural component details).

[0087] This embodiment uses a BIM theme library to store the calculation process of indicators, approval conclusions, and related component information (such as "reinforcement ratio of 2.6% corresponds to beam component ID=001"), forming a complete chain of approval evidence. This allows the competent authority to verify the data source and modification traces at any time. For example, if a company objects to the conclusion that "structural safety does not meet standards," the regulatory department can retrieve the original model parameters, calculation formulas, and comparison basis through the theme library, quickly respond to the dispute, and make a fair decision, thereby enhancing the credibility and transparency of supervision.

[0088] To better implement the above methods, this application also provides a BIM-based engineering supervision device.
