Description

Technical Field

[0001] This invention belongs to the field of cost estimation technology, specifically relating to a cost estimate generation system and method based on a standard bill of quantities set. Background Technology

[0002] In existing technologies, project cost lists are typically prepared by qualified tendering parties or project cost consultants and then reviewed by auditors. The preparers rely on traditional pricing software to create the bill of quantities based on design drawings and relevant specifications. However, due to different preparation practices, bills of quantities for similar projects often differ, making manual review and standardization labor-intensive and inefficient.

[0003] In addition, cost estimation tasks originate from different owners' tender documents and contracts. Due to the different formats and requirements, cost estimators need to manually match the scope and quantities of work, which can easily lead to omissions and repeated revisions of the bill of quantities, further reducing work efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a cost list generation system and method based on a standard list set, which can improve the completeness and accuracy of the project cost list composition, thereby facilitating the matching and pricing of subsequent engineering quantities.

[0005] The technical solution adopted in this invention is: a cost list generation system based on a standard list set, including a standard list generation module, a standard list set module, a standard list display module, and a cost list generation module;

[0006] The standard list generation module is used to generate a standard list based on externally imported lists and instructions, and store the standard list in a specified hierarchical directory under the standard list collection module.

[0007] The Standards List Collection module is used to create hierarchical directories based on different types of standards, costs, and projects, and to store the corresponding standards lists in the hierarchical directories.

[0008] The standard list display module is used to display the hierarchical directory of the standard list collection module, and import the standard list under the specified hierarchical directory into the cost list generation module according to external instructions;

[0009] The cost list generation module is used to display the imported list and, based on external instructions, delete or add items from the standard list and set price information and quantities to generate the cost list.

[0010] This invention provides a method for generating a cost list based on a standard bill of quantities set, employing the cost list generation system based on a standard bill of quantities set described above, and includes the following steps:

[0011] The standard list generation module generates a standard list and stores it in the specified hierarchical directory of the standard list collection module;

[0012] The Standards List Collection module generates a hierarchical directory based on different types of standards, costs, and projects, and stores the corresponding standard lists in the hierarchical directory.

[0013] The standard list display module displays the hierarchical directory of the standard list collection module, and imports the standard lists under the specified hierarchical directory into the cost list generation module according to external instructions;

[0014] The cost list generation module displays the imported list and, based on external instructions, deletes or adds items from the standard list and sets price information and quantities to generate the cost list.

[0015] The beneficial effects of this invention are as follows: The method relies on a standardized bill of quantities (BOQ) database, enabling cost estimators to quickly compile project BOQs, facilitating subsequent matching of quantities and pricing, and effectively improving work efficiency. Simultaneously, the standardized BOQ database, through standardized categorization, allows users to accurately and clearly select BOQ items under similar process and scheme conditions. When matching information provided by designers, it can quickly identify omissions or errors caused by insufficient professional expertise or human factors. Furthermore, this invention simultaneously collects BOQ price data while establishing the BOQ database, laying a solid foundation and providing a methodological reference for the formation of BOQ information prices in the future.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but these descriptions do not constitute a limitation on the present invention.

[0030] Example 1

[0031] like Figure 1 As shown, the present invention provides a cost list generation system based on a standard list set, including a standard list generation module, a standard list set module, a standard list display module, and a cost list generation module;

[0032] The standard list generation module is used to generate a standard list based on externally imported lists and instructions, and store the standard list in a specified hierarchical directory under the standard list collection module.

[0033] The Standards List Collection module is used to create hierarchical directories based on different types of standards, costs, and projects, and to store the corresponding standards lists in the hierarchical directories.

[0034] The standard list display module is used to display the hierarchical directory of the standard list collection module, and import the standard list under the specified hierarchical directory into the cost list generation module according to external instructions;

[0035] The cost list generation module is used to display the imported list and, based on external instructions, delete or add items from the standard list and set price information and quantities to generate the cost list.

[0036] Specifically, users can directly import completed cost list files into the standard list generation module, using them as standard lists and associating them with a selected hierarchical directory of a standard list collection module. Alternatively, users can use the cost list currently generated in the cost list generation module as a standard list and associate it with a selected hierarchical directory of a standard list collection module. The lowest level of the hierarchical directory of the standard list collection module can correspond to multiple standard lists. This invention can continuously optimize the standard list library as data accumulates.

[0037] Specifically, it also includes a historical cost list generation module, which stores historical cost lists and imports specified historical cost lists into the cost list generation module according to external instructions; the cost list generated by the cost list generation module is automatically stored in the historical cost list generation module as a historical cost list.

[0038] Preferably, in the process of using this invention, if the cost estimator already knows that the current project is similar to a previous project, they can directly call the cost list of that previous project from the historical cost list generation module, open it through the cost list generation module, and the user can make adaptive modifications to the existing cost list to generate the cost list for the current project. This process is simple and efficient, greatly improving work efficiency.

[0039] Preferably, the historical cost list generation module has a query function, allowing cost estimators to locate cost lists for past projects through keyword searches, effectively improving work efficiency.

[0040] Specifically, the cost list generation module is also used to generate cost list names and determine project types based on external instructions; the standard list display module selects and displays the corresponding hierarchical directory based on the determined project type.

[0041] Preferably, users select a project type by inputting commands, and the standard display module selects and displays a hierarchical directory that matches the selected project type based on the input commands, thereby improving the efficiency of users searching and browsing the overall directory. Users can also select a cost type by inputting commands. The cost type can be such as bid cost analysis, cost target, construction drawing budget, subcontract settlement, etc. The selected cost type is marked in the system to represent the cost stage and is used by users to distinguish cost lists later, but it is not used for subsequent directory division.

[0042] Preferably, users can continuously scroll down the hierarchical directory using external input commands to locate the standard list applicable to the current project. Users can import multiple standard lists into the cost estimate generation module for display, thus providing diverse choices and ensuring that the generated cost estimate meets the user's current needs.

[0043] Specifically, it also includes a unit price analysis module, which is used to generate reference price information for any item in the current cost list generated by the cost list generation module, based on the price information and set quantity information of specified items in the specified historical cost list or standard list.

[0044] The cost list generation module uses the reference price information corresponding to the project in the unit price analysis module as the set price information for display.

[0045] Preferably, based on external instructions, the unit price analysis module is activated for a specific item in the current cost list generated by the cost list generation module (this item already has a set quantity of work). The unit price analysis module selects several items from historical cost lists or standard lists and sets their corresponding quantities to correspond to the quantities of the currently selected item in the cost list generation module. The underlying logic of this operation is that a specific item in the currently generated cost list with a set quantity of work can be broken down into several items from historical cost lists or standard lists, combined according to the set quantities. Therefore, by calculating the total price of several items with set quantities in historical cost lists or standard lists, the total price of a specific item in the currently generated cost list with a set quantity of work can be obtained, thus yielding the unit price of that item in the current cost list. The unit price analysis module can draw on past experience and combine it with actual needs to obtain a reference unit price for individual items, improving work efficiency while ensuring the rationality of price settings.

[0046] Specifically, it also includes an information price module, used to generate an information price file based on a specified historical cost list or standard list; the information price file includes the project and its corresponding unit price information price; when the same project is in multiple specified lists, the average unit price of the project in multiple lists is used as the unit price information price of the project;

[0047] The cost list generation module calls the specified information price file in the information price module and displays the information price corresponding to the items in the currently generated cost list.

[0048] Preferably, users can use external input commands to start the cost list generation module to generate the cost list name and determine the project type, while using the information price module to associate the currently generated cost list with the specified information price file.

[0049] Users can also directly activate the information price module via external commands, and then call a specified historical cost list or standard list according to the external commands. The information price module automatically extracts the items and their corresponding unit price information from the specified list to form an information price file. After the information price file is generated, it can display relevant information and conclusions such as the highest and lowest prices, average prices, and median prices, which can provide cost engineers with reference information without having to look through previous materials, effectively improving work efficiency. When the cost list generation module calls the information price file from the information price module, it only uses the web crawler function to search for the information price of each item in the currently created cost list.

[0050] If the user does not specify an information price file through the information price module when starting the cost list generation module, the information price will not be displayed.

[0051] Alternatively, if a certain item and its price information do not exist in the specified information price file, the information price for that item will not be displayed. This invention, through its information price module, integrates the standard list set and historical lists to further provide price information guidance for the currently being prepared cost list, offering users effective historical data support.

[0052] Specifically, it also includes a cost comparison module, which is used to generate and display comparison details and comparison summaries for a specified historical cost list based on external instructions; the comparison details include differences in quantities, unit prices and total prices between the specified historical cost lists; the comparison summary is a conclusion on the reasons for the differences generated based on the items, quantities and unit prices of the comparison details.

[0053] Preferably, users can view existing historical cost lists and standard lists from the standard list compilation module and historical list generation module through the cost comparison module. Users can select at least two historical cost lists and standard lists by inputting commands. The cost comparison module uses a web crawler to obtain consistent items and their price information from the selected lists, and compares the prices, quantities, and costs of the same item in different lists to form a comparison conclusion. Simultaneously, it compares the overall differences in items and prices between the two lists, analyzes the reasons for the differences from multiple dimensions, provides users with diversified analytical conclusions, and achieves effective cost list comparison analysis.

[0054] Since both historical cost lists and standard cost lists use the same standardized template for project names and layout, the cost comparison module can efficiently and accurately obtain comparison conclusions, making it convenient to provide users with reference opinions.

[0055] Specifically, it also includes a template management module, which is used to generate and store templated cost lists (hereinafter referred to as template lists) according to external instructions, and to import the specified templated cost lists into the cost list generation module according to external instructions.

[0056] Preferably, users can customize templates of various subcategories through the template management module, and directly import the template list into the cost list generation module when compiling the cost list, effectively improving work efficiency.

[0057] Specifically, the hierarchical directory of the standard list collection module includes an engineering classification directory and a standard classification directory; wherein:

[0058] The first-level category of the engineering classification directory is classified according to the engineering type, the second-level category is classified according to the total cost components of each engineering project, and the second-level category is further classified according to the different engineering projects or cost items under each cost component. The last level of the engineering classification directory corresponds to at least one standard list.

[0059] The standard classification directory is divided into three levels: the first level is classified according to the type of project; the second level is classified according to different standards under each type of project; and the third level is a list of standards corresponding to each standard.

[0060] like Figure 2 As shown, when the primary category is EPC general contracting projects, the cost structure is based on the technological processes of wind power and photovoltaic power generation, referencing the actual budget preparation regulations and cost standards for photovoltaic / onshore wind farm projects, and combining the company's own cost composition characteristics to organize and classify costs. First, vertically, a full-scope cost composition element for the general contracting project is formed, and then horizontally, costs are decomposed from three levels: unit project, sub-item project, and bill of quantities. The full-scope cost composition includes five parts: construction and installation costs, equipment and material procurement costs, consulting services and other fees, company costs, and provisional sums / provisional estimates. Secondary projects in the cost decomposition can be prepared with reference to the actual budget preparation regulations and cost standards for photovoltaic / onshore wind farm projects.

[0061] Preferably, this invention can efficiently generate cost estimates for new energy projects. Due to the special nature of new energy projects, their sub-projects are numerous and complex, but the overall construction content of each individual project is clear.

[0062] Furthermore, through the unit price analysis module of this invention, the construction content of a single project in a new energy project can be effectively and reasonably broken down, and the corresponding sub-items and their corresponding prices can be retrieved from historical cost lists or standard lists to form a combination to form a reference unit price for a single project, thereby improving work efficiency while ensuring the rationality of unit price setting.

[0063] Furthermore, due to the standardized design of new energy projects, the information price module allows for efficient and intuitive reference to prices in previous cost lists, eliminating the need for users to search through documents. Simultaneously, users can continuously update the information price file based on constantly generated new cost lists, enabling continuous system optimization.

[0064] Furthermore, the cost comparison module can compare the specific costs of different new energy projects, providing effective data support for the subsequent work of cost estimators.

[0065] Furthermore, due to the complex construction content of new energy projects, a single project may involve multiple independent unit projects. By setting template lists for different unit projects in the template management module, the template lists can be prioritized when compiling cost estimates, effectively improving the efficiency of cost estimate production.

[0066] Specifically, it also includes a user information module, which stores and verifies the user's account and password and their permissions, and grants access to verified users; the access permissions include the cost list under the corresponding permissions of editing, merging and reviewing.

[0067] It also includes a permission association module, which is used to associate the cost list with the user's editing, merging and review permissions based on external instructions;

[0068] It also includes an audit module, which is used to display the cost list under the user's audit permissions and receive the audit conclusions from the user, and display the audit conclusions of the cost list under the user's editing permissions;

[0069] It also includes a file merging module, which is used to merge cost lists under the user's merging permissions to generate a new cost list based on external instructions.

[0070] Preferably, the user enters their account and password through the login interface. The user information module receives and verifies the entered account and password. For users who pass verification, they are redirected to the operation interface. This invention ensures that only specific users can edit specific cost lists by setting corresponding permissions, thus guaranteeing the assistance and effectiveness of cost list preparation and management.

[0071] After completing the cost estimate, users can automatically navigate to the review permission associated interface by clicking the corresponding button on the operation interface. In this interface, users can enter commands, including the reviewer's information. The permission association module receives the reviewer's information and grants that reviewer access to the cost estimate, effectively adjusting the reviewer's access permissions in the user information module.

[0072] After completing the cost estimate, users can automatically navigate to the merge permission associated interface by clicking the corresponding button on the operation interface. In this interface, users can enter commands, including information about the personnel involved in the merge. The permission associated module receives the personnel information and grants them merge permissions, effectively adjusting their usage permission information in the user information module.

[0073] After logging into the system, users can view the cost estimates pending review, the cost estimates that have been reviewed, and the review conclusions of the cost estimates submitted for review through the review interface.

[0074] Meanwhile, different users can create separate cost lists for different items of the same project, and then view all cost lists that can be merged under the specified merging permissions by activating the file merging module. Multiple cost lists can then be selected and merged into a single, unified cost list.

[0075] This invention, through streamlined permission settings, ensures that the comparison, creation, merging, and review of cost estimates can all be carried out within the same system, effectively improving the efficiency of the cost estimation process.

[0076] The specific usage process of the present invention will be further described below with reference to specific embodiments.

[0077] Users log in to the system with their username and password. After verification, they are granted access to the operation page. Users can view editable, mergeable, and auditable cost estimates within their user permissions on this page. Clicking on the corresponding cost estimate name allows users to perform editing, merging, or auditing operations.

[0078] The standard manifest collection is already stored in the standard manifest collection module in the system backend. For example... Figure 3 As shown, users can access the input command dialog box by clicking the "New" button in the operation interface.

[0079] Users enter basic information about the cost document in the instruction dialog box: a custom cost list name, the selected cost type, and the standard general list (i.e., selecting the corresponding project type); select "Information Price Document"; and quickly reference the pre-created template list by clicking "Template" to start the template management module.

[0080] The “Cost Type” is divided according to the stage of cost document formation, such as bid cost analysis, cost target, construction drawing budget, subcontract settlement, etc. The corresponding label is generated according to the selected cost type to mark the cost type of the final cost list.

[0081] Based on the selected "Standard Master List," the simplified standard list display module shows the hierarchical directory, template list, and information price document, displaying only the hierarchical directory, template, and information price document for the selected project type. The template list and information price document are marked with the corresponding project type during creation.

[0082] like Figure 9 As shown, clicking "Templates" launches the template management module, and a dialog box will appear on the page displaying the list of available templates under the selected "Standard Master List" type. Figure 10 As shown, clicking "Information Price File" will launch the information price module, and a dialog box will appear displaying the available information price files under the selected "Standard Master List" type. After selecting the corresponding file, click "OK" to return to the previous screen. Figure 3 The page shown.

[0083] After completing the instructions in the dialog box, click "OK" to launch the cost estimate generation module, which will then redirect you to the cost estimate preparation page. Figure 4 As shown. In this specific embodiment, the cost type is selected as cost target; the standard master list (i.e., the corresponding project type) is selected as power engineering. No template list is selected in this embodiment.

[0084] The standard list display module, based on the selection of "Power Engineering", calls up the corresponding hierarchical directory and the corresponding forms under the directory in the standard list collection module, and displays them on the left side of the cost list preparation page.

[0085] Users can locate the lowest level standard form by pulling down the hierarchical directory on the left side of the cost list preparation page, and add the standard form to the cost list preparation page.

[0086] Alternatively, users can use the "Import" button to launch the historical cost list generation module, locate a historical cost list similar to this project by searching, import it into the cost list generation module, and then display it on the cost list compilation page.

[0087] Alternatively, users can launch the template management module via the "Template" button and import a list of templates.

[0088] Users can add items to the imported list to meet their current needs.

[0089] Users can delete all quantity data in the current form by clicking "Clear Quantity with One Click" and delete all unit price data in the current form by clicking "Clear Unit Price with One Click".

[0090] The information price module automatically fills in the information price based on the selected information price file and the project information written in the current form.

[0091] After setting the quantity for any item in the bill of quantities, you can click the icon in the corresponding "Unit Price Analysis" section to launch the unit price analysis module. For example... Figure 5 As shown, after starting the unit price analysis module, click "Add Item" in the pop-up dialog box to select either the historical cost list or the standard cost list. Figure 6 As shown, further select reference items for unit price analysis from the selected list. For example... Figure 7 As shown, users can select several different reference items under different lists for unit price analysis and set the quantity of each reference item accordingly. The unit price analysis module sums the unit price and quantity of each reference item to obtain the total price of the selected items in the currently generated cost form. This total price is then divided by the set quantity to obtain the reference unit price of the selected items, which is automatically filled into the unit price column. Users can manually modify the filled unit price information.

[0092] Users can set the unit price for each item based on the conclusions displayed in the unit price analysis module and the information price module. After confirming that all items have been added and all quantities and unit prices have been set, users can click the "Calculate and Save" button at the bottom of the cost list compilation page to generate the cost list.

[0093] Once the user has verified that the cost list is correct, they can set the reviewer for the cost list.

[0094] like Figure 11 As shown, users can click the "Cost Document Comparison" button on the main page to launch the cost document comparison module. A dialog box will automatically pop up on the main page. Under the selected "Standard General Bill of Quantities," users can further select a historical cost list belonging to the "Power Engineering" type. The cost document comparison module will automatically generate a comparison module based on the selected historical cost list, as shown below. Figure 12 The comparison data shown.

[0095] like Figure 13 As shown, users can click the "Merge Cost Documents" button on the main page to launch the cost document merging module. A dialog box will automatically pop up on the main page, allowing users to further select historical cost lists belonging to the "Power Engineering" type under the selected "Standard Master Bill of Quantities". The cost document comparison module will automatically generate a merged cost list based on the selected historical cost lists.
