Description

Technical Field

[0001] The present invention relates to the technical field of information processing, and in particular to a method and system for rapid statistics of engineering quantities. Background Art

[0002] The project quantity refers to the physical quantity of the project, which is the quantity of each sub-item or sub-item project and components expressed in physical or natural units of measurement.

[0003] Revit is a professional building information modeling (BIM) software that can help architects and engineers design and manage projects more efficiently. The model optimization function can help users quickly and accurately calculate the project quantity, saving time and energy. Completing the project quantity calculation based on the Revit platform has the following advantages:

[0004] 1. Calculation rules can be used to calculate quota quantities and list quantities to make up for the problem that Revit's native function only has physical quantities.

[0005] 2. For construction companies, the bill of quantities can be used to directly locate the corresponding component positions in the model and clearly see the properties and spatial positions of the components. Compared with project features described in words, it can more directly display information, properties and practices, which is more conducive to quotation.

[0006] 3. The bill of quantities calculated and output by the Revit platform can correspond to the components in the model one by one, and be linked with the component quantities, so that there is a real basis for reference and evidence for inquiry. In addition, due to the in-depth design role in the 3D model production process, the possibility of changes is greatly reduced, so the work of both parties to check the quantity of work will be greatly reduced in the future.

[0007] However, the existing method of completing engineering quantity calculation based on the Revit platform also has some disadvantages, such as: it consumes a lot of computer resources, and Revit calculations often take up a lot of computer resources. When summarizing and calculating a large model, the system may even prompt "Insufficient memory, need to close Revit". In addition, a lot of manual operations are required during the calculation process, such as parameter setting, model mapping and other processes, which need to be manually configured by the software operator during the calculation process. Not only does this method place high demands on the professional ability of the software operator, but it is also inefficient and prone to errors. Summary of the invention

[0038] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention, and for ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0039] Figure 1 This is a flow chart of a method for quickly calculating engineering quantities provided by an embodiment of the present invention;

[0040] Figure 2 The present invention is a schematic diagram of the structure of a rapid engineering quantity statistics system provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0041] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0042] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0043] When calculating the quantity of work based on the Revit software model, the model file will not be modified in any way. The processing method is to create a quantity calculation database file in the same directory of the Rvt file, and all the data related to the quantity calculation are stored in the database file. The file includes the following information: project setting data (selected list library, list calculation rules, list default output settings, etc.), attribute mapping data, floor mapping data, model mapping data, component quantity calculation attribute data, etc. At the same time, the quantity calculation data is also saved in the database file.

[0044] The following first briefly describes the process of completing engineering quantity calculation based on the Revit platform in the prior art.

[0045] After obtaining the BIM model, open the BIM model through the Revit quantity calculation software, and then perform the following operations:

[0046] (1) Project settings, mainly including the following functions: Project list selection, the purpose is to determine the calculation rules (mainly including deduction rules) of the components to be calculated, the output content of the project quantity, list items and other information. After the calculation rules are set, they will be stored in the database file (bima) automatically generated by the software to ensure that all the software settings remain unchanged when the project file is opened next time.

[0047] (2) Model mapping: converting Revit components into components that the software needs to calculate.

[0048] Match materials and structural types according to the names. When the ideal match is not achieved according to the family name, the family name can be modified or the conversion rule settings can be adjusted to improve the default matching success rate. According to the family and family type names in the Revit model and the quantity calculation components: During design and modeling, the families and family types of the model components built are named differently due to different designers, such as "rectangle-column-500x500" or "KZ-500x500", etc. This requires matching and mapping the family type names in the BIM model with the quantity calculation component names, and mapping the BIM models with family type names such as "rectangle-column-500x500" or "KZ-500x500" built by the design into the quantity calculation model of "column" or "frame column" in the quantity calculation software, which can calculate the engineering quantity according to the rules.

[0049] (3) List attachment, that is, attaching the list to the component to realize the association between the BIM model component and the list item, and setting the corresponding engineering quantity calculation formula and engineering quantity merging conditions in the list (after the engineering quantity calculation, the list item characteristics are formed). In this way, when calculating the engineering quantity, the engineering quantity calculation formula and engineering quantity merging conditions in the associated list can be used to calculate the engineering quantity results, and the engineering quantity calculation results can be filled in the engineering quantity calculation formula of the list, and the list merging conditions can be filled in the list item characteristics.

[0050] (4) Summarize the calculations and output the quantities of the model components (list quantities, physical quantities). You can also export the detailed itemized quantity list or other quantity tables.

[0051] The above-mentioned engineering settings and model mapping processes need to be completed manually by software operators. The list attachment is mainly done by software operators manually plugging the list or importing the list table into the list attachment interface, which is not only time-consuming and inefficient, but also prone to errors.

[0052] To this end, the present invention provides a method and system for rapid engineering quantity statistics, which pre-sets a parameter configuration database and a model mapping rule library; when performing engineering quantity statistics, the parameter configuration database is read to automatically complete parameter settings; floor mapping and attribute mapping are automatically completed according to the model mapping rule library, and Revit components are converted into components that can be recognized by the software; an association is established between components in the BIM model and items in the list to complete the list connection; the engineering quantity is calculated according to the list to obtain the engineering quantity of the model component; and a report is output according to the calculation results.

[0053] The solution of the present invention is based on the secondary development of the Revit platform, directly utilizes the Revit design model, and according to the relevant construction engineering pricing quota rules, directly completes the engineering quantity calculation and analysis on the Revit platform, quickly outputs the calculation results, and can be directly used by the pricing software.

[0054] like Figure 1 FIG. 1 is a flowchart of a method for quickly calculating engineering quantities provided by an embodiment of the present invention, comprising the following steps:

[0055] Step 101, pre-set the parameter configuration database and model mapping rule library.

[0056] The parameter configuration database includes but is not limited to a list library and / or a quota library. The quota library is a database containing the labor, material and machinery consumption standards and corresponding costs required for various construction engineering components; the list library includes one or more list items, and each list condition includes any one or more of the following information: engineering quantity calculation rules, engineering quantity output content.

[0057] Furthermore, corresponding engineering quantity calculation formulas and engineering quantity merging conditions may also be set in the list.

[0058] The model mapping rule library includes but is not limited to: the corresponding relationship between the building elevation of the components in the BIM model and the floors in the engineering quantity calculation, and the mapping relationship between the names and attributes of the components in the BIM model and the names and attributes of the components in the engineering quantity calculation.

[0059] Step 102, when performing engineering quantity statistics, read the parameter configuration database to complete parameter setting.

[0060] Different from the prior art, in the embodiment of the present invention, the Revit software can read the parameter configuration database to complete the parameter setting without the need for manual setting by the software operator.

[0061] Step 103, completing floor mapping and attribute mapping according to the model mapping rule library, automatically completing model mapping, and converting Revit components into components that can be recognized by the software.

[0062] Similarly, in the embodiment of the present invention, the Revit software can complete the floor mapping and attribute mapping according to the model mapping rule library. For example, the building elevation of the model component is automatically read. In addition, manual adjustment of the read data can also be supported.

[0063] During the engineering quantity calculation process, the engineering quantity is calculated based on fixed attributes, such as "concrete strength grade". In the embodiment of the present invention, the modeling specification can be set up in advance during the design modeling to standardize the naming of components and attribute items. The software will match the attribute mapping in advance in the database, and the software operator can directly call it without manual configuration.

[0064] The operating idea of ​​the existing BIM quantity calculation software is to convert Revit components into components that can be recognized by the software. During design and modeling, different designers may name the families and family types of the model components differently, such as "rectangle-column-500x500" or "KZ-500x500", etc. Therefore, it is necessary to match and map the family type names and quantity calculation component names in the BIM model, and map the BIM models with family type names such as "rectangle-column-500x500" or "KZ-500x500" built by the design into the quantity calculation model of "column" or "frame column" in the quantity calculation software, which can calculate the engineering quantity according to the rules. In the existing quantity calculation and statistical process based on the Revit platform, when performing model mapping, the software operator needs to manually adjust the component mapping classification to improve the matching success rate.

[0065] In the solution of the present invention, the rule base can be configured in advance based on the component naming standard in the modeling standard, and the association relationship between the component name and the component keyword can be established and stored in the database. In this way, when performing model mapping, the model mapping process can be automatically completed without manual adjustment by the software operator.

[0066] Furthermore, in order to ensure the accuracy of the model mapping, a model mapping result report can be generated after the model mapping is completed.

[0067] Furthermore, the report content can be located and checked to better ensure the accuracy of the model mapping.

[0068] It can be seen that from the model perspective, by standardizing the model component names, the components can be quickly and accurately located through the component names; from the software perspective, the model mapping accuracy can be improved, the software operation time can be shortened, and work efficiency can be improved.

[0069] Step 104, establish an association between the components in the BIM model and the items in the list, and complete the list attachment.

[0070] Specifically, a keyword of a component name in the BIM model is obtained; and an association between the component in the BIM model and an item in the list is established according to the keyword.

[0071] The said list attachment refers to realizing the association between BIM model components and list items. Furthermore, the corresponding engineering quantity calculation formula and engineering quantity merging conditions can be set in the list (after the engineering quantity is calculated, the characteristics of the list items are formed). In this way, when calculating the engineering quantity, the engineering quantity calculation formula and engineering quantity merging conditions in the associated list can be used to calculate the engineering quantity results, and the engineering quantity calculation results can be filled in the engineering quantity calculation formula of the list, and the list merging conditions can be filled in the list item characteristics.

[0072] In the prior art, the main method of list attachment is to manually apply the list or import the list table into the list attachment interface. This operation method is time-consuming and inefficient.

[0073] In the solution of the present invention, automatic attachment of the list is achieved by reading the component name keywords (the component naming has been standardized through modeling before modeling). After the automatic attachment is completed, only a quick check and correction are required, which not only reduces the difficulty of operation, but also greatly saves working time and improves work efficiency.

[0074] Step 105, calculating the engineering quantity according to the list to obtain the engineering quantity of the model component.

[0075] For example, the following calculations may be included but are not limited to: merging engineering calculation data; summarizing and calculating the engineering quantities of project model components according to the list quota template, calculation rules, list quota library, etc. The specific calculations may be determined according to actual needs, and the embodiments of the present invention do not limit this.

[0076] Step 106: Output a report based on the calculation results.

[0077] When the inventory is not attached, a physical quantity information report is output. The physical quantity information report may include but is not limited to any one or more of the following: a physical quantity summary report, a physical quantity floor summary report, a physical quantity detailed report, etc.

[0078] When the list is attached, a list information table is output, which may include but is not limited to any one or more of the following: a list summary table, a list floor summary table, a list detail table, etc.

[0079] The formats of the physical quantity information table and the inventory information table may be, for example, any one or more of the following: EXCEL, XML, and PDF.

[0080] According to actual needs, you can also choose to export, print or save the corresponding report.

[0081] The method for rapid engineering quantity statistics provided by the present invention pre-sets a parameter configuration database and a model mapping rule library; when performing engineering quantity statistics, parameter setting, floor mapping, attribute mapping, and model mapping can be automatically completed; operations such as list hanging can be efficiently completed, which can greatly improve the efficiency and accuracy of engineering quantity calculation based on Revit.

[0082] Accordingly, the present invention also provides a system for rapid statistics of engineering quantities, such as Figure 2 The figure shows a structural diagram of the system.

[0083] The engineering quantity rapid statistics system 200 includes the following modules:

[0088] A calculation module 205 is used to calculate the engineering quantity according to the list to obtain the engineering quantity of the model component;

[0089] The report output module 206 is used to output a report according to the calculation results.

[0090] The engineering quantity rapid statistics system provided by the present invention converts the BIM model into a quantity calculation model through the setting of model mapping, and calculates the engineering quantity by reading the three-dimensional information of the BIM model and combining the engineering quantity calculation rules, including volume, template area, length, surface area, projection area, etc. The scheme of the present invention can greatly improve the efficiency and accuracy of engineering quantity calculation based on Revit.
