Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and in particular to a method, system, terminal and medium for constructing 5D-BIM component-level data measurement for water conservancy projects. Background Technology

[0002] Currently, water conservancy projects are characterized by large scale, long construction period, numerous participants, and high technical complexity. Typical projects include deep foundation pit excavation, TBM tunnel construction, and large cofferdam pouring. Traditional project measurement and management models are no longer sufficient to meet the needs of modern project management, and the following are the main prominent problems: I. The phenomenon of information silos is serious. Data from different stages, such as design, construction, cost estimation, and operation and maintenance, are fragmented. BIM models are used only as visualization tools and lack effective linkage with core business data such as schedule, cost, and quality. For example, the geometric information of components in the design stage cannot be directly linked to the measurement list in the construction stage, and the quality acceptance data in the construction stage is difficult to synchronize to the cost accounting stage. This results in the measurement work requiring repeated manual verification and data entry, which is inefficient and prone to errors.

[0003] II. The management granularity is too coarse. Traditional measurement management often uses "sub-projects" or "processes" as units, which cannot accurately locate specific "components" (such as a pile foundation, a TBM segment, or a cofferdam slab). Taking pile foundation engineering as an example, traditional measurement can only count the total quantity of a certain sub-project, and cannot distinguish the construction progress, quality status, and measurement status of individual pile foundations. This leads to insufficient decision-making basis and makes it difficult to achieve accurate investment control and quality accountability.

[0004] 3. Poor data dynamism and linkage Cost and schedule information updates are lagging and cannot be linked with the 3D model in real time. For example, when the construction schedule is adjusted or the actual amount of work deviates from the plan, the measurement data needs to be manually recalculated and updated to the relevant documents. It cannot be automatically synchronized through the model, making it difficult to achieve dual control of "investment-schedule" and easily causing risks such as exceeding the budget and delays in the construction period.

[0005] IV. Insufficient traceability Measurement data for components throughout their entire lifecycle, from design and construction to operation and maintenance, are scattered across different systems or documents, lacking a unified, interconnected carrier. When quality issues or measurement disputes arise, it becomes impossible to quickly trace the construction team, material batch, acceptance records, and measurement details of a particular component, hindering problem investigation, responsibility determination, and review of similar projects.

[0006] V. Limitations of Existing BIM Technology Applications Current BIM technologies primarily focus on 3D geometric visualization. While there has been initial exploration in 4D (time) and 5D (cost) domains, a standardized measurement methodology system that spans the entire project lifecycle, uses components as the smallest management unit, and deeply integrates business data is lacking. Most BIM tools can only enable model browsing and simple quantity surveying, failing to meet the full-process business needs such as measurement rule configuration, quality linkage control, hierarchical review, electronic signatures, and payment linkage, making it difficult to truly implement and apply them to actual engineering measurement management.

[0007] Therefore, there is an urgent need for a measurement method that can break down information barriers, refine management granularity, and achieve dynamic data linkage and full life cycle traceability in order to solve the above-mentioned problems in traditional water conservancy project measurement management and improve the level of precision, visualization and intelligence of measurement work.

[0008] Therefore, existing technologies still have shortcomings. Summary of the Invention

[0009] To address the aforementioned deficiencies in existing technologies, this invention provides a method, system, terminal, and medium for constructing 5D-BIM component-level data measurement for water conservancy engineering projects. The technical solution adopted by this invention is as follows: In a first aspect, the present invention provides a method for constructing 5D-BIM component-level data measurement based on water conservancy engineering projects, the method comprising: A 5D-BIM model is created based on a preset component classification and coding system. The imported construction drawing budget list is broken down, and the measurement method is set for the broken-down components in the platform. The measurement permissions of each component are forcibly associated with the construction quality acceptance data. Create a current measurement period, filter out measurable components for the current period, automatically summarize the list data associated with the measurable components, and generate and submit a measurement declaration form; The measurement declaration forms are subject to hierarchical approval. Based on the approved measurement declaration forms, the state of the 5D-BIM model is driven to change synchronously. The approved measurement declaration forms are then summarized into the measurement report book for signing and encryption. Based on the aforementioned metering report book, a payment application is initiated and a report is generated. After the payment is completed, all metering-related data is linked and archived through the aforementioned component classification and coding system.

[0010] In one implementation, a 5D-BIM model is created based on a pre-defined component classification and coding system, including: Based on the BIM model design delivery standards and the characteristics of water conservancy projects, a component classification and coding system combining multi-layer tree structure and sequence number was developed. Based on the component classification and coding system, a domestically produced lightweight graphics engine is used to create a BIM model containing 3D geometric information of the components. The created BIM model covers all coded components in the component classification and coding system. The schedule is linked to each component in the created BIM model to clarify the construction sequence of each component and form a 4D construction simulation. By binding cost information to each component in the created BIM model, a 5D cost database is established, realizing a one-to-one mapping between components, unit prices, and costs, thus obtaining a 5D-BIM model.

[0011] In one implementation, the imported construction drawing budget list is split into smaller parts, and a measurement method is set for each split component in the platform, including: Submit the offline, fixed construction drawing budget list to the platform implementation unit, and complete the standardized import through the data interface to ensure that the construction drawing budget list is consistent with the contract agreement; Select the corresponding components from the project component library according to the project component and assign the quantities accordingly; According to the contract, a measurement method is set for each component in the platform. The measurement method includes: one-time measurement upon completion and batch measurement. The one-time measurement upon completion method does not require setting a measurement ratio, while the batch measurement method requires setting a measurement ratio.

[0012] In one implementation, the measurement permissions for each component are forcibly linked to the construction quality acceptance data, including: Upload the construction quality acceptance documents and submit them for supervision and approval; The platform automatically matches construction quality inspection data with corresponding components through a component classification and coding system. It automatically unlocks the measurement permission for the corresponding ratio of a component only after the quality inspection of the associated process is qualified. For components that have not been inspected or have failed inspection, the measurement function is locked and no application can be submitted.

[0013] In one implementation, a current measurement period is created, and the measurable components for the current period are selected, including: Add a current measurement period to the unit price list tab of the construction measurement module in the platform. It will be automatically synchronized to the total price list and supplementary measurement tab. The cumulative declared amount for the current period can be viewed in the successfully created current measurement period. Based on the measurement method and quality acceptance results of each component, the measurement status of the component is automatically determined, and for components without a measurement ratio, 100% of the project quantity is extracted. For components with measurement ratios, extract the quantities of work for the corresponding qualified measurement ratios of the work processes.

[0014] In one implementation, the inventory data associated with the measurable components is automatically aggregated, and a measurement declaration form is generated and submitted, including: In the intermediate measurement module, select the measurable components, and automatically summarize the list data associated with the components. The list data includes: quantity, unit price, and project characteristics. After completing the inspection report information and confirming that the declared amount is correct, generate a measurement declaration form and submit the measurement declaration form to the review process.

[0015] In one implementation, the measurement declaration forms are subject to tiered approval. Based on the approved measurement declaration forms, the state of the 5D-BIM model is synchronously changed. The approved measurement declaration forms are then aggregated into a measurement report book for signing and encryption, including: The supervision unit and the project command center review the metering declaration form, update the review progress data in real time during the review process, and synchronize the review results to the current period's metering summary data; The state of the 5D-BIM model is synchronously changed based on the approved measurement declaration form, and the data in the approved measurement declaration form is written into the component-level data dashboard to complete the full life cycle traceability of measurement data. Summarize the approved measurement declaration forms and write them into the measurement report book according to the preset standard format; After the construction party verifies that the contents of the measurement report booklet are correct, they sign it with one click and submit it to the supervisor for review. After the supervisor approves it, they jointly affix an electronic seal to the measurement report booklet document with the construction party. After the signing is completed, an uneditable version of the measurement report booklet is automatically generated.

[0016] Secondly, embodiments of the present invention also provide a 5D-BIM component-level data measurement system for constructing water conservancy engineering projects, wherein the system is used to implement the steps of the above-described method for constructing 5D-BIM component-level data measurement for water conservancy engineering projects, and the system includes: The list import and component-level splitting module is used to create a 5D-BIM model based on a preset component classification and coding system, split the imported construction drawing budget list, set the measurement method for the split components in the platform, and forcibly associate the measurement permissions of each component with the construction quality acceptance data. The measurable screening module is used to create the current measurement period, filter out the measurable components in the current period, automatically summarize the list data associated with the measurable components, and generate and submit the measurement declaration form. The measurement declaration form approval module is used to perform hierarchical approval of the measurement declaration forms, drive the state of the 5D-BIM model to change synchronously based on the approved measurement declaration forms, and summarize the approved measurement declaration forms into the measurement report book for signing and encryption. The measurement data and payment linkage module is used to initiate payment applications and generate expense reports based on the measurement report book, and after payment is completed, to link and archive all measurement-related data through the component classification coding system. Thirdly, this embodiment of the invention also provides a terminal, wherein the terminal includes a memory, a processor, and a measurement program for constructing 5D-BIM component-level data for water conservancy projects stored in the memory and executable on the processor. When the processor executes the measurement program for constructing 5D-BIM component-level data for water conservancy projects, it implements the steps of the measurement method for constructing 5D-BIM component-level data for water conservancy projects as described above.

[0017] Fourthly, embodiments of the present invention also provide a computer-readable storage medium, wherein the computer-readable storage medium stores a 5D-BIM component-level data measurement program for constructing water conservancy projects, and the 5D-BIM component-level data measurement program for constructing water conservancy projects implements the steps of the 5D-BIM component-level data measurement method for constructing water conservancy projects as described in any of the above schemes on the computer-readable storage medium.

[0018] Beneficial Effects: Compared with existing technologies, this invention provides a 5D-BIM component-level data measurement method for water conservancy engineering projects. First, a 5D-BIM model is created based on a preset component classification and coding system. The imported construction drawing budget list is then broken down, and measurement methods are set for the broken-down components within the platform. The measurement permissions for each component are forcibly associated with construction quality acceptance documents. Next, a measurement period is created for the current period, and measurable components are selected. The list data associated with the measurable components is automatically summarized, and a measurement declaration form is generated and submitted. Then, the measurement declaration forms undergo hierarchical approval. Based on the approved measurement declaration forms, the state of the 5D-BIM model is synchronously changed, and the approved measurement declaration forms are summarized in the measurement report book for signing and encryption. Finally, a payment application is initiated based on the measurement report book, and a reimbursement form is generated. After payment is completed, all measurement-related data is linked and archived through the component classification and coding system.

[0019] This invention creates a component classification and coding system, establishes a dynamic correlation mechanism between components and multi-source business data such as schedule, cost, and quality, and constructs a component-level 5D-BIM data model to achieve refined, visualized, and intelligent management of the entire process of water conservancy project measurement, providing accurate data support for project investment control, schedule management, and quality accountability.

[0035] To address the problems of existing technologies, this embodiment provides a 5D-BIM component-level data measurement method for water conservancy projects. This method enables refined, visualized, and intelligent management of the entire measurement process for water conservancy projects, providing precise data support for project investment control, schedule management, and quality accountability. In practical application, this embodiment first creates a 5D-BIM model based on a preset component classification and coding system. The imported construction drawing budget list is then broken down, and measurement methods are set for the broken-down components on the platform. The measurement permissions of each component are forcibly associated with construction quality acceptance documents. Next, a measurement period is created, and measurable components are selected. The list data associated with the measurable components is automatically summarized, and a measurement declaration form is generated and submitted. Then, the measurement declaration forms undergo hierarchical approval. Based on the approved measurement declaration forms, the state of the 5D-BIM model changes synchronously, and the approved measurement declaration forms are summarized into a measurement report book for signing and encryption. Finally, a payment application is initiated based on the measurement report book, and a payment invoice is generated. After payment is completed, all measurement-related data is linked and archived through the component classification and coding system.

[0036] The 5D-BIM component-level data measurement method for water conservancy engineering projects described in this embodiment can be applied to terminals, including intelligent product terminals such as computers. Specifically, as shown in the example... Figure 1As shown in the figure, the 5D-BIM component-level data measurement method for water conservancy engineering projects in this embodiment includes the following steps: Step S100: Create a 5D-BIM model based on the preset component classification and coding system, split the imported construction drawing budget list, set the measurement method for the split components in the platform, and forcibly associate the measurement permissions of each component with the construction quality acceptance data.

[0037] Combination Figure 2 As shown, the core logic of this invention's 5D-BIM component-level data measurement method for water conservancy projects is as follows: A 5D-BIM model is constructed using a component classification and coding system as the core thread. The "list-component" binding is achieved through the breakdown of the construction drawing budget list. Measurable components are selected based on the linkage between measurement methods and quality. After hierarchical review, standardized report books are generated. Finally, payment applications are linked, and data traceability and archiving are completed. The entire process embodies the core ideas of "data standardization - business process optimization - intelligent management," achieving refined management of the entire lifecycle of water conservancy project measurement.

[0038] Specifically, this embodiment, based on BIM model design delivery standards and the characteristics of water conservancy projects, formulates a component classification and coding system combining a multi-layered structure tree and sequence numbering. The structure of the component classification and coding system is as follows: First level (project): Use the first letter of the pinyin of the project abbreviation, such as "Gongming Reservoir-Qinglinjing Reservoir Connection Project" is abbreviated as "GMQSK"; The second layer (sub-items) is divided according to the functional zones of the project, such as "water intake" being abbreviated as "QS" and "water conveyance tunnel" being abbreviated as "SSD". The third level (specialty): divided by engineering specialty, such as "Civil Engineering" abbreviated as "TJ", and "Mechanical and Electrical Equipment" abbreviated as "JD"; The fourth layer (route): divided according to the specific engineering route or area, such as "GK0-115.8-GK0-145.8" (station interval); Fifth layer (section): Divided by section project, such as "earthwork excavation" abbreviated as "TFKW", "pile foundation engineering" abbreviated as "ZJGC"; The sixth layer (sub-items): divided according to sub-items of the project, such as "general earthwork excavation" abbreviated as "WYBTF", and "mud wall protection bored pile" abbreviated as "NJHBGZGZ"; Serial number: Numbered sequentially according to the number of components, such as "01" and "02".

[0039] After the above component classification and coding system is established, a coding standard library needs to be built in the platform to support the query, addition, modification and export of component codes, so as to ensure that all participants use unified coding rules and avoid data association errors.

[0040] Furthermore, this embodiment employs a domestically developed lightweight graphics engine (such as the BIMCore engine adapted for water conservancy projects) to create detailed 5D-BIM models at the component level. Specifically, this includes: based on the aforementioned component classification and coding system, using a domestically developed lightweight graphics engine, creating a BIM model containing the 3D geometric information of the components. The created BIM model covers all coded components in the aforementioned component classification and coding system. This embodiment can create BIM models containing the 3D geometric information of components one by one according to the component coding system based on design drawings, achieving construction-level accuracy. For example, the pile foundation model needs to include details such as pile diameter, pile length, and reinforcement layout; the earthwork excavation model needs to include parameters such as excavation range, depth, and slope; the "sand retaining wall LSK49" component of the Gongming Reservoir project requires a 3D model that accurately reflects its size, location, and spatial relationship with surrounding components. Next, the schedule is associated with each component in the created BIM model to clarify the construction sequence of each component, forming a 4D construction simulation that clarifies the start time, completion time, and process logic of each component. For example, the Work Breakdown Structure (WBS) for pile foundation engineering is decomposed into "pile foundation layout → hole drilling → steel reinforcement processing and installation → concrete pouring → finished product acceptance." Each process corresponds to a specific pile foundation component, and the construction sequence of each component can be intuitively displayed in the model, forming a 4D construction simulation. Finally, this embodiment binds cost information to each component in the created BIM model, establishing a 5D cost database to achieve a one-to-one mapping between components, unit prices, and costs, resulting in a 5D-BIM model. The 5D-BIM model in this embodiment can not only reflect the 3D geometric information of each component but also its unique code.

[0041] In other implementations, this embodiment can also perform lightweight processing on the created 5D-BIM model, employing model compression, texture simplification, and Level of Detail (LOD) technology to ensure smooth loading and operation of the model on web, mobile, and large-scale scenarios. For example, when viewing the overall engineering model of the Gongming water intake on the web, the components display simplified geometry; clicking on a single component automatically loads a high-precision detailed model and associated data. Furthermore, this embodiment can establish a mapping relationship library between multi-source business data and the 5D-BIM model through the unique code of each component, enabling dynamic association and fusion of data. Multi-source business data includes Internet of Things (IoT) monitoring data, quality acceptance data, material and equipment data, and construction management data. Specifically, the association and fusion with the 5D-BIM model includes: Internet of Things (IoT) monitoring data: Real-time monitoring data such as stress, strain, and settlement of components are connected to the platform through sensor interfaces and bound to the corresponding component codes. For example, strain monitoring data of TBM segments are associated with specific segment components through the code "GMQSK-SSD-TJ-GK0-205.8-GK0-235.8-GPJS-GPSJ-06", and the real-time monitoring curves can be viewed in the model.

[0042] Quality acceptance data: Quality data such as inspection batch documents for sub-projects, test reports, and acceptance records for concealed works are linked to components through coding. For example, the strength test report for pile foundation concrete pouring is linked to the corresponding pile foundation component code, serving as supporting documentation for measurement verification.

[0043] Material and equipment data: Material purchase orders, equipment arrival and acceptance records, and material batch information are linked to the components that use the material / equipment through coding. For example, the purchase record of a certain batch of cement is linked to the code of the cofferdam component that used that batch of cement, enabling precise material traceability.

[0044] Construction management data: Data such as construction team information, machinery shift records, and progress change orders are linked to components through coding. For example, the construction team for the component "Earthwork Excavation GK0-145.8-GK0-175.8" is "Civil Engineering Section 2, Team 1", and the machinery shift is "3 excavators". "Tian" and these data are all linked to component codes, forming a complete construction management file.

[0045] After integration, a component-level data dashboard is constructed. By clicking on any component in the platform, users can view its 3D geometric model, progress status, cost information, quality acceptance records, monitoring data, material usage, and all related information, providing comprehensive data support for measurement decisions. The platform in this embodiment is a component measurement platform, an integrated business platform specifically developed for water conservancy engineering measurement scenarios, supported by 5D-BIM component-level data management as its underlying technology.

[0046] Furthermore, based on the 5D-BIM model constructed above, this embodiment breaks down the macroscopic construction drawing budget list into microscopic component-level measurement units, clarifies the measurement scope and quantity of each component, and solves the problem of coarse granularity in the management of sub-projects in traditional measurement.

[0047] In practical application, this embodiment submits the offline-fixed construction drawing budget list to the platform implementation unit, and completes standardized import through the data interface to ensure that the construction drawing budget list is consistent with the contract agreement. The content of this construction drawing budget list includes a list of sub-items, a list of provisional items, a list of other items, a list of regulatory fees, a list of taxes, etc., specifically as follows: Figure 3As shown in the diagram, the platform receives the construction drawing budget list through standardized data interfaces (such as Excel import and API integration). It then automatically verifies whether the list format, project codes, and units of measurement conform to specifications. If format errors or duplicate codes are found, the platform automatically prompts and allows modifications. After successful verification, the construction drawing budget list is stored in the platform's contract list database, supporting online viewing, retrieval, and export.

[0048] Next, this embodiment will import the construction drawing budget list, select corresponding components from the project component library according to project location, and assign quantities. Specifically, as follows: Figure 4 As shown in the example, in this embodiment, the construction party can select corresponding components from the engineering part library according to the engineering part in the platform's bill of quantities splitting module, decomposing the quantities of the bill of quantities item to specific components. The specific operation process is as follows: In the platform, select the bill of quantities item to be split from the contract bill of quantities library, and then click "Select Part" to select the corresponding component from the engineering part tree. Next, according to the design drawings and construction plan, assign the decomposed quantities to each selected component, ensuring that the sum of the decomposed quantities of all components is less than or equal to the total contract quantity. Finally, fill in the splitting instructions (such as "Assign quantities by construction section"), click save, and the platform automatically binds the splitting results with the component codes, generating a "Bill of Quantities-Component-Quantity" association table, which supports exporting to Excel format for filing.

[0049] In this embodiment, during the breakdown process, the platform verifies the rationality of the broken-down quantities in real time. If the broken-down quantity of a component exceeds its design quantity or contract total, the platform automatically pops up a warning message: "Break-down quantity exceeds the upper limit, please adjust," ensuring the accuracy of the breakdown data. For example, in a highway rapid transit project, the "mud-walled bored pile" item (list code 040301004001) has a contract total of 38m / pile. When broken down to the No. 3 pier pile foundation-01 component, the broken-down quantity is 38m. If an attempt is made to input 40m, the platform immediately triggers a warning. If discrepancies are found between the construction drawing budget list and the bidding list during construction (such as discrepancies between the actual excavation quantity and the list quantity), the construction party's technical personnel can submit a list change application on the platform, upload the change basis (such as design change order, site visa form), and submit it to the supervision unit and the owner for review. After the review is approved, the platform updates the list data, and the construction party re-breaks the list to ensure that the breakdown result is consistent with the actual project.

[0050] Furthermore, this embodiment allows for the setting of measurement methods for each component within the platform according to contractual agreements. These measurement methods include: one-time completion measurement and batch measurement. In practical application, in the platform's measurement rule configuration module, the construction party sets a measurement method for each component according to the contract. The platform supports two measurement methods: one-time completion measurement and batch measurement. One-time completion measurement is suitable for small components and ancillary works that do not require phased measurement, such as "water intake retaining wall ancillary structure" and "management building renovation project." This method does not require setting a measurement ratio; 100% quantity measurement is automatically triggered after all sub-projects corresponding to the component are completed and pass final acceptance. Batch measurement is suitable for large components and projects with long construction cycles, such as pile foundation engineering, tunnel excavation engineering, and structural concrete engineering, which require phased measurement according to construction procedures. This method requires setting a measurement ratio, specifically a "procedure-measurement ratio" association rule, clearly defining the measurement ratio corresponding to each procedure.

[0051] Furthermore, this embodiment forcibly links the component's measurement permissions with the quality acceptance results; components that fail quality acceptance cannot initiate measurement. In practical application, the project command center, based on industry standards such as the "Regulations for Quality Inspection and Evaluation of Water Conservancy and Hydropower Engineering Construction," formulates quality inspection procedures and form templates for each sub-project and distributes them to the platform. For example, the quality inspection procedure for earthwork excavation is "Construction Self-Inspection → Team Re-Inspection → Supervisor Spot Check," and the required forms include the "Earthwork Excavation Construction Record," "Compaction Test Report," and "Hidden Works Acceptance Record." Next, the construction quality acceptance documents are uploaded and submitted for supervisor approval. Specifically, the construction party creates an inspection batch for each component in the platform's quality inspection module and uploads the corresponding quality inspection documents according to the quality inspection procedure. For example, for the "Earthwork Excavation GK0-175.8-GK0-205.8" component, the construction self-inspection record, compaction test report (compaction degree ≥ 95%), and supervisor spot check record are uploaded and submitted for supervisor approval. Then, the platform automatically matches the construction quality inspection data with the corresponding components through the component classification and coding system. If the supervisor approves the quality inspection data of a certain process of the component (that is, the quality acceptance of a certain process of the construction is qualified), and the process is bound to the measurement ratio, the platform automatically unlocks the measurement permission of the corresponding ratio; if the quality inspection data is not uploaded or the review is not approved, the measurement permission remains locked, and the construction party cannot select the component to declare measurement in the intermediate measurement module.

[0052] This embodiment establishes a measurement method and a quality-measurement linkage mechanism to ensure the compliance and accuracy of measurement work, and solves the problems of ambiguous measurement timing and disconnect between quality and measurement in traditional measurement.

[0053] Step S200: Create the current measurement period, filter out the measurable components for the current period, automatically summarize the list data associated with the measurable components, and generate and submit the measurement declaration form.

[0054] Combination Figure 5 As shown, in this embodiment, a new measurement period can be added to the unit price list tab of the construction measurement module on the platform. This is automatically synchronized to the total price list and supplementary measurement tab. Data such as the cumulative declared amount for the current period can be viewed in the successfully created current measurement period. Next, the platform automatically determines the measurement status of components based on the time range, measurement method, and quality acceptance results of the measurement period, and filters out the measurable components for the current period. Specifically, for components without a measurement ratio, 100% of the quantity is extracted. For components with a measurement ratio, the quantity of the corresponding qualified measurement ratio for the work process is extracted. That is, if a component is set to be measured in one go upon completion and completes final acceptance within the measurement period, and is determined to be in an unreported and unaccepted state, it is included in the list of measurable components. If a component is set to be measured in batches, and a certain work process passes quality acceptance within the measurement period, and is determined to be in an unreported and unaccepted state, the quantity of the corresponding qualified measurement ratio for the work process can be extracted and included in the list of measurable components.

[0055] Furthermore, in this embodiment, the platform's intermediate measurement module selects measurable components and automatically aggregates the associated list data for each component. This list data includes: quantity, unit price, and project characteristics. Next, the inspection report information is completed, and after confirming the declared amount is correct, a measurement declaration form is generated and submitted to the review process. In practical application, this embodiment's platform supports two measurement declaration methods: one-click batch generation and manual addition. When selecting one-click batch generation, the contractor selects "Select All" on the platform and clicks "Generate Declaration Form with One Click." The platform automatically extracts the quantity, unit price, and project characteristics of all measurable components, generating a unified measurement declaration form. When using the manual addition method, the contractor clicks the "+ Add" button on the platform to add intermediate measurement data, manually selecting specific components (such as components for supplementary measurement) in the component tree to generate a personalized measurement declaration form.

[0056] Furthermore, in other implementations, in this embodiment, after the measurement declaration form is generated, the construction party completes the relevant information in the measurement editing section of the platform's intermediate measurement module to ensure the completeness and accuracy of the declaration data, such as... Figure 6As shown, the specific improvements are as follows: Basic Information: Fill in the payment number, measurement object, and measurement location. The platform will automatically calculate the declared amount. Sub-item Fee Adjustment: If there is a difference between the actual construction quantity and the quantity separated from the construction drawing budget list, the contractor should edit the quantity in the Sub-item Fee tab, fill in the reason for the adjustment, and upload the site visa slip as supporting evidence. The platform will automatically verify whether the adjusted quantity is reasonable. If it exceeds the deviation threshold, it needs to be submitted to the supervisor for additional review. Add Unit Price Measures Fee: If the measurement item involves unit price measures fee (such as large machinery entry and exit fees, scaffolding erection and dismantling fees), the contractor should add a fee item in the Unit Price Measures Fee tab of the platform, fill in the fee name, unit, unit price, and quantity. The platform will automatically summarize it into the declared amount. After all information is complete, the contractor clicks the submit button on the platform to submit the measurement declaration form to the supervision unit for review. The platform automatically records information such as the applicant, declaration date, and declared amount, generating a declaration record that supports querying and exporting.

[0057] Step S300: The measurement declaration forms are subject to hierarchical approval. Based on the approved measurement declaration forms, the state of the 5D-BIM model is driven to change synchronously. The approved measurement declaration forms are then summarized into the measurement report book for signing and encryption.

[0058] This embodiment allows for the review of the measurement declaration form by both the supervision unit and the project command center. During the review process, the review progress data is updated in real time, and the review results are synchronized to the current period's measurement summary data. In this embodiment, the platform employs a two-tier review process: "Supervision Unit → Project Command Center." Specifically, the supervision personnel log into the platform's measurement review module, receive the measurement declaration form submitted by the construction party, and review it according to the following process: 1. Document Completeness Review: Check whether the basic information, sub-item fees, measure fees, sketches, attachments, etc. in the measurement declaration form are complete. If key documents are missing (such as test reports not uploaded), click "Return" on the platform and fill in the reason for return (such as "Concrete strength test report is missing, please supplement"). The construction party can resubmit after supplementing the documents.

[0059] 2. Data Accuracy Verification: Verify the consistency between the declared quantities and the actual quantities on site. Supporting data such as the 3D model of the component, construction records, and on-site supervision records can be viewed through the platform. For example, when verifying the declared quantities for the component "Earthwork Excavation GK0-205.8-GK0-235.8", the supervisor can view the excavation range and depth in the model and compare it with the excavation data in the construction records. If the declared quantities do not match the actual quantities, the verified quantities can be adjusted directly on the platform.

[0060] 3. Quality compliance review: Click the inspection batch hyperlink in the measurement declaration form on the platform to check whether the quality inspection data of the component has been approved. If the quality inspection data fails or there are quality problems, the measurement declaration will be rejected.

[0061] 4. Submit the review results: After the review is approved, click "Approved" on the platform and fill in the review comments (such as "The submitted data is accurate and meets the measurement requirements"); if the review is not approved, click "Rejected" and specify the rectification requirements.

[0062] During the review process, the platform updates the review progress data in real time. The construction party can view the review status (pending review, under review, passed, rejected) and receive review comments in the measurement application record module on the platform. For example, after a measurement application form is submitted, the status shows "under review (supervisor)". After the supervisor approves it, the status is updated to "pending review by project command".

[0063] Next, project command personnel log into the platform, receive the measurement declaration forms approved by the supervisor, and conduct a final review. This review includes: focusing on whether the measurement amount exceeds the contractual agreement, whether the adjustment of the project quantity is reasonable, and whether the cost calculation is accurate. If problems are found in the declared data (such as excessively high provisional fees), the audited amount can be directly adjusted, and the reason for the adjustment can be filled in. Project command personnel have the authority to reduce the declared quantity of any component, and the reduced portion is automatically returned to the component quantity database for subsequent measurement. After the project command approves the application, they click "Final Approval" on the platform. The platform automatically synchronizes the audit results to the current period's measurement summary data, updating the cumulative audited amount and the audited quantity / total declared quantity.

[0064] Furthermore, in this embodiment, the review process for lump-sum price measurement (such as other construction costs and safety monitoring engineering costs) and supplementary measurement (such as items added due to design changes) is consistent with that for unit price measurement. Lump-sum price measurement: The contractor adds a measurement item to the lump-sum price tab on the platform, fills in the item name, amount, and description, uploads the contract basis (such as lump-sum contract terms), and submits it for review by the supervisor and command center. Supplementary measurement: For new items such as design changes and site approvals, the contractor adds an item to the supplementary measurement tab on the platform, fills in the basis for the change (such as design change order number), quantity, unit price, and amount, uploads the changed drawings and approval records, and submits it for review according to the tiered review process. After approval, the platform automatically associates the supplementary measurement data with the relevant component codes to achieve data traceability.

[0065] Furthermore, this embodiment can drive the synchronous change of the 5D-BIM model's status based on the approved measurement declaration form, achieving a digital twin effect of "data changes, model changes." Specific updates include: progress status updates, cost data updates, and quantity updates. Specifically, progress status updates: different colors are used to mark the measurement status of components in the model; for example, measured components are marked in green, unmeasured components in gray, and components under review in yellow, visually displaying the measurement progress. Cost data updates: the measured amount and cumulative measured amount of components are automatically updated, and the deviation between planned and actual costs is displayed in real time in the component-level data dashboard. Quantity updates: the measured and remaining measurable quantities of components are updated to ensure data accuracy in subsequent measurement declarations.

[0066] Next, the data from the approved measurement declaration form is written into the component-level data dashboard to form a complete measurement file, including information such as the application time, review time, reviewer, application amount, review amount, and reasons for adjustment, thus completing the full lifecycle traceability of measurement data; Furthermore, this embodiment summarizes the approved measurement declaration forms and writes them into the measurement report book according to a preset standard format. In specific applications, it is combined with... Figure 7 As shown, after all unit price, total price, and supplementary measurements for the current period have been approved, the construction party selects the corresponding measurement period in the report generation module of the platform and clicks "Generate Report Book." The platform automatically completes the following operations: 1. Data Summary and Extraction: Extracts data from all approved measurement declaration forms for the current period, including sub-item engineering costs, total price measures costs, regulatory fees, taxes, etc., and summarizes and calculates them according to the format requirements of the "Specification for Pricing of Water Conservancy Engineering Quantities List." 2. Report Format Generation: Automatically generates standardized report books, including forms such as "Interim Payment Certificate," "Bill of Quantities Pricing Table," "List and Pricing Table for Sub-item Engineering and Unit Price Measures," "List and Pricing Table for Total Price Measures," and "Pricing Table for Regulatory Fees and Taxes." The report book format is consistent with the paper report and supports online preview and printing. 3. Automatic Data Filling: Automatically writes the summarized and calculated data into the corresponding columns of the report book, eliminating the need for manual entry. 4. The construction team previews the report booklet on the platform to verify the accuracy of the data. If any data errors are found (such as the omission of a certain cost summary), they can return to the measurement audit module to view the specific declared data. After confirming the problem, they can contact the supervisor or command center for re-audit. After verification, click "Confirm Generation," and the platform will lock the data in the measurement report booklet, preventing modification.

[0067] Furthermore, after the construction party verifies that the contents of the measurement report book are correct, they can sign it with one click and submit it to the supervisor for review. After the supervisor approves it, they will jointly affix an electronic seal to the measurement report book document with the construction party. After the signing is completed, the measurement report book will automatically generate an uneditable version.

[0068] The platform in this embodiment uses electronic signature and digital encryption technology. The specific process is as follows: 1. Contractor's signature: The authorized personnel of the contractor (such as the project manager) insert the digital certificate U-shield, click "Sign" in the platform, enter the U-shield password, and the platform automatically embeds the electronic signature into the "Contractor" column of the measurement report book.

[0069] 2. Supervision unit's signature: The chief supervising engineer of the supervision unit logs in to the platform, views the signed report book submitted by the construction party, and after verifying that it is correct, inserts the digital certificate U-shield, clicks "signature", enters the password, and the platform embeds the electronic seal of the supervision unit into the "chief supervising engineer" column.

[0070] 3. Digital Encryption: The platform uses digital certificates issued by the seal server to encrypt electronic signatures, ensuring that the signatures are tamper-proof and forgery-proof. Simultaneously, image processing technology is used to transform the electronic seals into a visual effect identical to that of paper document stamps, guaranteeing the standardization of measurement reports.

[0071] 4. Uneditable and Locked: After signing, the platform automatically generates a non-editable PDF file of the measurement report booklet, which can be downloaded, saved, and uploaded to the group's PM management platform for filing. If you attempt to modify the content of the measurement report booklet, the electronic signature will automatically become invalid, and the platform will display the message "The file has been tampered with, and the signature is invalid."

[0072] Step S400: Initiate a payment application and generate a bill based on the metering report book, and after the payment is completed, archive all metering-related data through the component classification coding system.

[0073] Specifically, after the measurement report book is signed and stamped, the platform automatically synchronizes the measurement-related data to the two payment management modules and the group PM management platform. During synchronization to the payment management module, core data such as the current period's completed amount, cumulative completed amount, and amount payable from the measurement report book are synchronized to the platform's payment management module, providing data support for payment applications. During synchronization to the group PM management platform, this embodiment uses an API interface to synchronize the measurement data (including the report book PDF file, measurement declaration form, and audit records) to the group PM management platform, achieving centralized management and sharing of project data. During the synchronization process, the platform automatically verifies data consistency. If synchronization fails (e.g., due to network interruption), it automatically retryes and logs the process to ensure no data loss. The construction party can view the synchronization status in the platform's data synchronization record module; if synchronization fails, they can manually trigger a resynchronization.

[0074] Next, the payment application and invoice generation process is initiated. The contractor can initiate a payment application based on synchronized measurement data in the platform's payment application module. The specific steps are as follows: select the corresponding measurement period and measurement report book; fill in the payment request period, the requested payment amount, and bank account information; upload a signed and stamped PDF file of the measurement report book as an attachment; finally, click "Submit Application" to submit the payment application to the owner for review. The platform automatically reads the data from the measurement report book and generates an invoice, which includes the payment application number, project name, contract number, current period measurement amount, requested payment amount, and attachment list. Currently, the payment management module supports manual entry of supplementary information (such as material adjustment amounts and advance payment deduction amounts). In the future, fully automated linkage between measurement data and payment applications will be achieved, eliminating the need for manual intervention.

[0075] After payment is completed, the platform links and archives all measurement-related data using unique component codes, forming a complete measurement traceability chain. This chain includes: bill of quantities breakdown records (bill of quantities-component-quantity association table); quality acceptance documents (inspection batch forms, test reports, acceptance records); measurement declaration documents (measurement declaration forms, sketches, calculation formulas, attachments); review records (supervisor review opinions, command center adjustment records); measurement report books and electronically signed documents; and payment vouchers (bank transfer records, payment approval forms). Users can query the full lifecycle measurement information of any component in the platform's measurement traceability module using keywords such as component code, project name, and measurement period.

[0076] In summary, compared with the prior art, the present invention has at least the following beneficial effects: 1. Break down information silos and achieve deep data integration: Establish dynamic association between 5D-BIM models and multi-source business data through unique component codes, break down data barriers in the design, construction, cost, and operation and maintenance stages, and achieve integrated management of schedule, cost, quality, and measurement data; 2. Refine management granularity and improve measurement accuracy: Using "component" as the smallest management unit, the measurement scope is refined from "sub-project level" to "component level", which can realize the measurement management of specific components such as single piles and a ring of pipe segments, providing accurate data support for investment control; 3. Dynamic linkage and updates for real-time dual control: The 5D-BIM model and measurement data are linked in real time. When the progress, cost or quality status changes, the model is updated synchronously. The deviation between the planned and actual costs can be calculated in real time to achieve dual control of "investment and progress". 4. Strengthen quality control and ensure metrological compliance: By mandating the linkage between quality and metrology, only components that have passed quality acceptance are allowed to initiate metrology, thereby eliminating the measurement of unqualified projects from the source and ensuring project quality and metrological compliance. 5. Full lifecycle traceability facilitates responsibility identification: All measurement-related data are archived through component codes, allowing for the traceability of measurement information throughout the entire lifecycle of components, from design and construction to operation and maintenance, providing a basis for quality accountability and review of similar projects; 6. Automated processes improve management efficiency: The system automates processes such as list splitting, screening of measurable components, generation of application forms, and summary of reports, reducing manual intervention and error rates. At the same time, electronic signatures and online approvals simplify processes and significantly improve the efficiency of metrology management. 7. Domestic technology support ensures independent control: The adoption of a domestically produced lightweight graphics engine, combined with an independently developed component coding system and data association mechanism, enables independent control of technology and promotes the digital transformation of water conservancy projects.

[0077] Based on the above embodiments, the present invention also provides a 5D-BIM component-level data measurement system for water conservancy engineering projects, such as... Figure 8 As shown, the system in this embodiment includes: a list import and component-level splitting module 10, a measurable filtering module 20, a measurement application form approval module 30, and a measurement data and payment linkage module 40. Specifically, the list import and component-level splitting module 10 is used to create a 5D-BIM model based on a preset component classification and coding system, split the imported construction drawing budget list, set the measurement method for the split components in the platform, and forcibly associate the measurement permissions of each component with the construction quality acceptance data. The measurable filtering module 20 is used to create the current measurement period, filter out the measurable components in the current period, automatically summarize the list data associated with the measurable components, and generate and submit the measurement application form. The measurement application form approval module 30 is used to perform hierarchical approval of the measurement application forms, drive the state of the 5D-BIM model to change synchronously based on the approved measurement application forms, and summarize the approved measurement application forms into the measurement report book for signing and encryption. The measurement data and payment linkage module 40 is used to initiate payment applications and generate expense reports based on the measurement report book, and after the payment is completed, to link and archive all measurement-related data through the component classification coding system.
