Description

Technical Field

[0001] The present invention relates to the field of construction engineering, and in particular to a measurement payment method and system based on a BIM model. Background Art

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. In the past, the measurement and pricing of construction projects usually adopted the manual pricing method of cost estimators, which required high professional quality of cost estimators and required a lot of effort. In recent years, the cost consulting industry usually uses traditional graphic quantity calculation software of companies such as Glodon, Chenxi, and Swell to build non-physical models, and runs the software's built-in quantity calculation rules to approximate and calculate the engineering quantity. Then, based on the pricing software combined with two-dimensional CAD drawings and cost experience, the drawing parameter information is manually entered to form a price list for each part of the engineering quantity list. Importing CAD drawings in batches and establishing a cost calculation model in traditional graphic quantity calculation software can reduce the manual quantity calculation work to a certain extent and improve work efficiency, but it still takes a lot of time. At the same time, each participating entity carries out quantity calculation and pricing activities on its own, and each project needs to be repeated many times. Moreover, due to the limitations of the practitioners' business level and the depth of understanding of two-dimensional drawings, it is easy to cause deviations in the results of each measurement. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a measurement payment method and system based on a BIM model in view of the deficiencies in the prior art.

[0004] The technical solution of the present invention to solve the above technical problem is as follows: a measurement payment method based on a BIM model, comprising:

[0005] Step 1, obtaining a bill of quantities output by a detailed design model, wherein the bill of quantities is generated according to a preset component information summary table and preset measurement and pricing rules;

[0006] Step 2, selecting target components that meet preset measurement and pricing conditions from the bill of quantities, wherein the target components are attached with component codes and cost attributes standardized according to a preset component information table;

[0007] Step 3, obtaining a contract list, and extracting price information of the target component from the contract list, wherein the price information is consistent with the measurement and pricing method of the target component in the bill of quantities;

[0008] Step 4: Match the preset measurement and pricing rules according to the cost attributes of the target component, and generate a payment slip corresponding to the bill of quantities in combination with the price information.

[0009] Furthermore, the preset measurement and pricing conditions include that the component has passed the quality inspection and evaluation, the component has no associated unresolved on-site issues and / or the component has a corresponding bill of quantities code.

[0010] Furthermore, the preset measurement and pricing rules are matched according to the cost attributes of the target components, and the payment slip corresponding to the bill of quantities is generated in combination with the price information. Specifically, it is determined whether the output unit and the measurement unit of the target components are consistent. If they are consistent, direct measurement and pricing are performed based on the number and unit price. If they are inconsistent, the corresponding conversion formula is called for pricing.

[0011] Furthermore, when generating a payment slip corresponding to the bill of quantities in combination with the price information, the section information and / or professional information of the target component is screened and deduplicated, and the screened target component details are summarized to form a corresponding payment slip.

[0012] Furthermore, it also includes an output value statistics step, specifically: after completing the measurement and pricing, determine whether the target process involved in the output value calculation is completed based on the on-site construction progress; if completed, obtain the target component information that meets the preset output value statistics conditions, perform output value statistics based on the target component information, and summarize and display the output value statistics results.

[0013] Furthermore, the payment order is also checked, specifically:

[0014] Traversing the target components to obtain components to be deducted that meet preset deduction conditions;

[0015] Determine whether the component to be deducted has been correctly deducted. If not, generate the associated components and corresponding association relationships of the component to be deducted through the BIM model of the in-depth design;

[0016] Query the preset deduction rules and generate corresponding deduction commands according to the association relationship;

[0017] Execute the deduction command to cut, switch the connection order and / or connect the corresponding components to be deducted and the associated components, adjust the metering priority of the components to be deducted and / or the associated components, and update the payment order according to the execution result.

[0018] Further, it is determined whether the component to be deducted is deducted correctly, specifically:

[0019] Obtaining the real-time measurement code of the component to be deducted;

[0020] Querying a preset measurement code table, and generating a target measurement code according to the component code of the component to be deducted;

[0021] It is determined whether the real-time measurement code is consistent with the target measurement code. If they are consistent, the component to be deducted has been correctly deducted.

[0022] Furthermore, it also includes a recording step, specifically: recording the payment amount before and after the payment order is updated and the measurement code of the corresponding component to be deducted and / or the associated component before and after the update.

[0023] Another technical solution of the present invention to solve the above technical problems is as follows:

[0024] A measurement payment system based on a BIM model comprises a first acquisition module, a screening module, a second acquisition module and a payment order generation module.

[0025] The first acquisition module is used to acquire a bill of quantities output by the detailed design model, wherein the bill of quantities is generated according to a preset component information summary table and preset measurement and pricing rules;

[0026] The screening module is used to screen out target components that meet preset measurement and pricing conditions from the bill of quantities, and the target components are attached with component codes and cost attributes standardized according to a preset component information summary table;

[0027] The second acquisition module is used to obtain the contract list, and extract the price information of the target component from the contract list, wherein the price information is consistent with the measurement and pricing method of the target component in the bill of quantities;

[0028] The payment order generation module is used to match the preset measurement and pricing rules according to the cost attributes of the target component, and generate a payment order corresponding to the bill of quantities in combination with the price information.

[0029] Furthermore, the payment order generation module is specifically used to determine whether the output unit and measurement unit of the target component are consistent. If they are consistent, the price is directly measured and calculated according to the number and unit price. If they are inconsistent, the corresponding conversion formula is called for pricing. If there is no corresponding conversion formula, a warning message is generated.

[0030] The beneficial effects of the present invention are as follows: the present invention provides a measurement and payment method and system based on the BIM model, which applies the BIM model to the quantity calculation of the bill of quantities by establishing a high-precision and high-standard BIM model, and realizes automatic matching and association between the model components and the bill of quantities by extracting the attribute information of the model components, which can not only save the calculation time and reduce repeated calculations, but also improve the work efficiency and accuracy of the measurement and pricing stage after quality inspection and evaluation.

[0031] Advantages of additional aspects of the present invention will be given in part in the following description, and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Figure 2 A structural block diagram of a metering payment system based on a BIM model provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention but not to limit the scope of the present invention.

[0035] like Figure 1 As shown, a measurement payment method based on a BIM model provided by an embodiment of the present invention includes:

[0036] S1, obtaining a bill of quantities output by a detailed design model, wherein the bill of quantities is generated according to a preset component information summary table and preset measurement and pricing rules.

[0037] The present invention first constructs a component information summary table, and defines the header contents of the common properties, modeling methods, geometric accuracy information, component properties, construction properties and cost properties of each component in the BIM design model in the component information summary table, and unifies the above contents according to the rules.

[0038] Specifically, in the component information table, when the project is in the design stage, the general attributes include the design management attributes, component management attributes, and component instance attributes of all components; the design management attributes are composed of majors, sub-majors, and secondary sub-majors in sequence; the component management attributes are composed of component categories, component families, and component types in sequence. When the project is in the construction stage, the general attributes include the construction management attributes, component management attributes, and component instance attributes of all components; the construction management attributes are composed of sub-divisional projects, sub-sub-divisional projects, and sub-item projects in sequence; the component management attributes are composed of component categories, component families, and component types in sequence.

[0039] The geometric accuracy information includes model output attributes, model output units, and accuracy requirements at different stages.

[0040] The component attributes include attribute classification, attribute name, attribute value rule, attribute value exhaustively listed according to the attribute value rule, and attribute unit.

[0041] The construction attributes include process number, process name, corresponding inspection batch form name, form number, project-level collection indicators, design requirements and specifications, data type and supervision actions.

[0042] The cost attributes include the list item code, list item name, list measurement unit, list item characteristics, the 3-digit serial number after the list code, output attribute, conversion formula and model output method.

[0043] In other words, the present invention defines standardized rules for the above-mentioned multiple attributes in the component information summary table, which not only makes the component classification clear, the component naming rules clear, and the geometric accuracy of each stage clear, but also the model structure of the same type of components matches the cost list structure, and the model output unit is consistent with the cost measurement unit, which facilitates the subsequent application of cost and measurement payment.

[0044] Then, based on the component information summary table and the modeling characteristics of the BIM software, the measurement and pricing rules of the BIM model that has been in-depth designed are established, and then the corresponding bill of quantities table is generated in combination with the measurement and pricing rules.

[0045] In a preferred embodiment, before issuing the bill of quantities, the BIM design model needs to be deepened, and quality inspection and evaluation shall be carried out based on the BIM model after the in-depth design. Then the corresponding bill of quantities shall be issued for measurement and payment. The in-depth design steps and quality inspection and evaluation steps will not be described in detail here.

[0046] Then, step 2 is executed to select target components that meet the preset measurement and pricing conditions from the bill of quantities. The target components are attached with component codes and cost attributes standardized according to the preset component information table. Specifically, the preset measurement and pricing conditions include that the component has passed the quality inspection and evaluation, the component has no associated unresolved on-site problems, and / or the component has the corresponding bill of quantities code. To determine whether these preset measurement and pricing conditions are met, it is only necessary to query the information attached to each component. In different embodiments, target components that meet any one or more of the above three conditions can be measured and paid, otherwise a corresponding warning message will be generated.

[0047] Then execute step 3 to obtain the contract list, extract and unify the price information of the target component from the contract list, so that the price information is consistent with the measurement and pricing method of the target component in the bill of quantities. Specifically, the price and price unit in the contract list can be identified through image recognition or OCR recognition technology, and the recognition result is converted according to the measurement and pricing method of the target component in the bill of quantities, such as pricing by weight, pricing by quantity or pricing by size, etc., combined with the cost attribute of the target component, so as to generate price information consistent with the measurement and pricing method. Then execute step 4 to match the preset measurement and pricing rules according to the cost attribute of the target component, and generate the payment slip corresponding to the bill of quantities in combination with the price information.

[0048] The above-mentioned embodiment loads all physical information, geometric information and other attributes of the engineering entity into the cost calculation system, and realizes online collaborative cost calculation among multiple parties such as design institutes, owners, BIM consulting, construction units, supervision units, and cost consulting. Automatic cost calculation based on BIM is realized through cost rules, BIM models, contract BOQ items, and intelligent matching of rules. At the time of completion or phased settlement, the owner unit and the construction unit use the same completed BIM model for project management and settlement. And according to the quality inspection results, on-site problem solving, whether the cost has been paid, etc., the calculation book and payment slip are automatically and instantly generated, the payment process is reviewed online, and the entire cost payment work is completed, thereby greatly simplifying the completion settlement process.

[0049] In a preferred embodiment, the preset measurement and pricing rules are matched according to the cost attributes of the target component, and the payment slip corresponding to the bill of quantities is generated in combination with the price information. Specifically, it is determined whether the output unit and the measurement unit of the target component are consistent. If they are consistent, the price is directly measured and calculated according to the number and unit price. If they are inconsistent, the corresponding conversion formula is called for pricing. If there is no corresponding conversion formula, a warning message is generated, thereby generating the measurement and pricing results more quickly and stably.

[0050] In a preferred embodiment, when generating a payment slip corresponding to the bill of quantities in combination with price information, the section information and / or professional information of the target component is also screened and deduplicated, and the screened target component details are summarized to form a corresponding payment slip, thereby better meeting user needs.

[0051] In a preferred embodiment, it also includes an output value statistics step, specifically: after completing the measurement and pricing, determine whether the target process involved in the output value calculation is completed according to the on-site construction progress. If it is completed, obtain the target component information that meets the preset output value statistics conditions, perform output value statistics according to the target component information, and summarize and display the output value statistics results. Specifically, in order to be able to monitor the project output value in real time, if the traditional manual statistics method is used, there are two problems: due to the large number of bidding sections, it is difficult to quickly and accurately count, and manual statistics not only consumes a lot of manpower, but also has the problem of untimely updates and inability to obtain the latest first-hand data. Therefore, the system can be used to count the output value in real time to achieve data accuracy and timeliness.

[0052] In the preferred embodiment, the goal of progress management can also be achieved. According to the progress management requirements, the model is split and integrated during the model in-depth design, and based on the engineering management platform, the model is used as a carrier to attach or associate information such as planned progress, actual progress, human resources, materials, and machinery for progress management. Specifically, by entering the image data of the actual progress into the BIM system platform through online collaboration, it is convenient for each construction party to obtain the image data of the actual construction of the project from the platform, reducing the information attenuation and changes caused by multi-level communication. At the same time, the actual progress and planned progress are entered into the BIM system platform, and the management can quickly obtain the deviation between the actual progress and the planned progress, as well as the actual occurrence time and completion time of each process, trace the cause of the deviation, control the project from a macro perspective, adjust the progress plan and resource allocation in time, and optimize project management.

[0053] The person in charge of BIM uploads the on-site image data to the system platform through the BIM system platform, connects it to the model, informs the relevant people of the on-site progress, and realizes the online collaborative management of the on-site construction progress. All participating parties can learn about the construction site situation in real time through the PC and mobile terminals. The technician or the corresponding BIM person in charge enters the planned progress and actual progress through the BIM system platform, and the platform intuitively displays the deviation value of the quantity progress in the form of a Gantt chart. It can be used as data support to urge the project to make timely progress adjustments. The model components are connected to the actual progress through the BIM system platform. According to the deduction of time, the deduction of the project progress can be intuitively viewed on the platform. Through the one-click statistics function, the completed project volume in any period can be quickly calculated.

[0054] In a preferred embodiment, the payment order is further verified, specifically:

[0055] The target components are traversed to obtain components to be deducted that meet the preset deduction conditions. In a specific embodiment, different preset deduction conditions and preset deduction rules are set according to the coding software or modeling software corresponding to the target components.

[0056] Determine whether the component to be deducted has been deducted correctly. If not, generate the associated components and corresponding association relationships of the component to be deducted through the BIM model of the in-depth design.

[0057] Query the preset deduction rules and generate corresponding deduction commands according to the association relationship.

[0058] Execute the deduction command to cut, switch the connection order and / or connect the corresponding components to be deducted and the associated components, adjust the metering priority of the components to be deducted and / or the associated components, and update the payment order according to the execution result.

[0059] The prior art usually uses software such as Revit for coding and model building. The deduction relationship between different components in different software is often inconsistent with domestic practices or actual engineering needs. For example, many families in Revit do not deduct the intersection with other components by default, which leads to errors in engineering quantity calculation. The above preferred embodiment verifies the target components that need to be deducted in the payment order, establishes the association relationship of the components that need to be deducted (such as overlapping components) according to the verification results and the BIM model, and adjusts the measurement priority to improve the accuracy of generating payment results.

[0060] In a preferred embodiment, judging whether the component to be deducted is correctly deducted is specifically as follows:

[0061] Obtaining the real-time measurement code of the component to be deducted;

[0062] Querying a preset measurement code table, and generating a target measurement code according to the component code of the component to be deducted;

[0063] It is determined whether the real-time measurement code is consistent with the target measurement code. If they are consistent, the component to be deducted has been correctly deducted.

[0064] In the above preferred embodiment, firstly, corresponding measurement codes are set for the deduction rules of target components in different software, and a preset measurement code table is formed. When a deduction is performed on a component, a corresponding measurement code is generated for the component, and the measurement code is linked to the component. At this time, the measurement code can be obtained by selecting the component in the BIM model. If the measurement code is not obtained, it means that the component has not been deducted. If the real-time measurement code of the component is inconsistent with the target measurement code obtained by looking up the table, it means that the deduction action is incorrect, and it is necessary to reversely check the cause and deduct again.

[0065] In another preferred embodiment, a recording step is further included, specifically: recording the payment amount before and after the payment order is updated and the measurement code before and after the corresponding component to be deducted and / or associated component is updated, thereby forming historical data to facilitate maintenance of the metering payment system.

[0066] In one embodiment, if Figure 2 As shown, a metering payment system based on a BIM model is provided, comprising a first acquisition module 100, a screening module 200, a second acquisition module 300 and a payment order generation module 400.

[0067] The first acquisition module 100 is used to acquire a bill of quantities output by a detailed design model, wherein the bill of quantities is generated according to a preset component information table and preset measurement and pricing rules;

[0068] The screening module 200 is used to screen out target components that meet the preset measurement and pricing conditions from the bill of quantities, and the target components are attached with component codes and cost attributes standardized according to the preset component information table;

[0069] The second acquisition module 300 is used to obtain the contract list, and extract the price information of the target component from the contract list, wherein the price information is consistent with the measurement and pricing method of the target component in the bill of quantities;

[0070] The payment order generation module 400 is used to match the preset measurement and pricing rules according to the cost attributes of the target component, and generate a payment order corresponding to the bill of quantities in combination with the price information.

[0071] In a preferred embodiment, the payment order generation module 400 is specifically used to determine whether the output unit and the measurement unit of the target component are consistent. If they are consistent, the price is directly measured and calculated according to the number and unit price. If they are inconsistent, the corresponding conversion formula is called for pricing. If there is no corresponding conversion formula, a warning message is generated.

[0072] In a preferred embodiment, the payment order generation module 400 is also used to filter and deduplicate the section information and / or professional information of the target component when generating the payment order corresponding to the bill of quantities in combination with the price information, and summarize the filtered target component details to form a corresponding payment order.

[0073] In a preferred embodiment, it also includes an output value statistics module 500, which is used to determine whether the target process involved in the output value calculation is completed according to the on-site construction progress after completing the measurement and pricing. If it is completed, the target component information that meets the preset output value statistics conditions is obtained, and the output value statistics are performed based on the target component information, and the output value statistics results are summarized and displayed.

[0074] In a preferred embodiment, a payment order verification module 600 is further included, and the payment order verification module specifically includes:

[0077] A command generating unit 603 is used to query the preset deduction rules and generate corresponding deduction commands according to the association relationship;

[0078] The updating unit 604 is used to execute the deduction command to perform cutting, switching connection order and / or connection actions on the corresponding components to be deducted and related components, adjust the metering priority of the components to be deducted and / or related components, and update the payment order according to the execution result.

[0079] In a preferred embodiment, the judgment unit 602 is specifically used to obtain the real-time measurement code of the component to be deducted, query the preset measurement code table, and generate a target measurement code according to the component code of the component to be deducted; and to judge whether the real-time measurement code and the target measurement code are consistent. If they are consistent, the component to be deducted has been correctly deducted.

[0080] In a preferred embodiment, a recording module 700 is further included, and the recording module 700 is used to record the payment amount before and after the payment order is updated and the measurement code of the corresponding component to be deducted and / or the associated component before and after the update.
