Description

Technical Field

[0001] The present invention relates to the technical field of engineering construction management, and particularly relates to a method for generating a core structure tree of quality cost for digital construction management of highways. Background Art

[0002] Quality control and cost control are two important objectives of highway construction management. Their operations are both different and interrelated.

[0003] First, for quality management, according to the "Highway Engineering Quality Inspection and Evaluation Standard" (JTG F80 / 1—2017), the construction drawings are divided into units, sub-units, sub-items / sub-sub-items, and a quality inspection and evaluation structure tree is established for quality inspection and evaluation and quality inspection data management.

[0004] An example of the quality inspection and evaluation structure tree is shown in Table 1:

[0005] Table 1 Example of the quality inspection and evaluation structure tree

[0006]

[0007] Second, compiling a measurement ledger is a basic task in cost management. The measurement ledger decomposes the construction drawings from large to small, from the whole to the part, until the smallest measurement unit according to the measurement rules of the bill of quantities agreed in the contract, and attaches the measurement bill of quantities to the smallest measurement unit to establish a measurement ledger structure tree for project measurement and cost management.

[0008] An example of the measurement ledger structure tree is shown in Table 2:

[0009] Table 2 Example of the measurement ledger structure tree

[0010]

[0011] Third, project measurement is based on the premise that the project entity is qualified in quality inspection and the quality inspection data is complete. For the convenience of management and to achieve business interoperability and data collaboration, a mapping relationship should be established between the measurement ledger structure tree and the quality inspection and evaluation structure tree through coding. However, due to the differences in the two structure tree systems and the different division methods, it is difficult to match the mapping relationship. In practice, the mapping relationship is often established manually one by one. Due to the large volume of the two structure trees, the workload of manually establishing the mapping relationship is large and it is easy to make mistakes, which restricts the automation and intelligence of digital construction management.

[0012] In addition, in practice, there is also a method of replacing the measurement ledger structure tree with a quality inspection and evaluation structure tree, that is, hooking up the measurement bill of quantities to the specified sub-project / sub-sub-project in the quality inspection and evaluation structure tree. Since the measurement unit is the engineering entity, and the sub-project is divided according to the construction process, technology or materials, there is often a many-to-one or one-to-many relationship between the sub-project and the measurement unit. Coupled with the fact that some sub-projects are priced but not measured (integrated in other sub-projects), this measure can only meet the basic needs of project measurement, but is not convenient for cost analysis and cost management. Summary of the Invention

[0013] In view of the above, the present invention provides a method for generating a core structure tree of quality cost list for highway digital construction management, which solves the problem that it is difficult for the existing quality inspection and measurement structure trees to be automatically mapped, and realizes business interconnection and data collaboration.

[0014] Technical solution of the present invention:

[0015] The present invention provides a method for generating a core structure tree of quality cost list for highway digital construction management, including:

[0016] I. Construct a hierarchical structure tree: Decompose the engineering project according to the hierarchy of unit project, sub-project, component (i.e., the smallest measurement unit), sub-project / sub-sub-project, and construct a core structure tree of quality cost list;

[0017] II. Define coding rules: Formulate unified coding rules and assign unique codes to each level of the project;

[0018] III. Implement mode conversion: According to different management requirements, convert the core structure tree of quality cost list into a quality inspection and evaluation structure tree and a measurement ledger structure tree respectively;

[0019] IV. Establish data association: Associate the quality inspection results of sub-projects / sub-sub-projects through component codes, and determine whether measurement can be carried out according to the quality inspection results, so as to realize the sharing of measurement and quality inspection data;

[0020] In the implementation of mode conversion, when converting the core structure tree of quality cost list into a quality inspection and evaluation structure tree, hide the component level, aggregate the sub-sub-projects under the same component to form sub-projects, and attach the relevant information of the component to the sub-sub-project information;

[0021] When converting the core structure tree of quality cost list into a measurement ledger structure tree, hide the sub-project / sub-sub-project level and directly display it to the component level.

[0022] Furthermore, in constructing the hierarchical structure tree, unit projects and sub-projects are divided according to the "Quality Inspection and Evaluation Standards for Highway Engineering" (JTG F80 / 1—2017); components are divided into the smallest measurement units according to the measurement rules of the bill of quantities; sub-projects / sub-sub-projects are divided based on component processes, procedures or materials according to the "Quality Inspection and Evaluation Standards for Highway Engineering" (JTG F80 / 1—2017).

[0023] Furthermore, in defining the coding rules, the coding separates the project information at each level through specified symbols.

[0024] Furthermore, in defining the coding rules, the structure tree coding is a coding system that identifies the projects at all levels in the core structure tree of the entire quality cost sheet. The structure tree coding is expressed in a tree structure of unit projects, sub-projects, components, sub-projects / sub-sub-projects. The codes of unit projects, sub-projects, and components are separated by a half-width "."; the codes of components and sub-projects / sub-sub-projects are separated by a half-width ":".

[0025] Furthermore, the project category coding is an integral part of the structure tree coding and is used to clarify the category to which each level of project belongs; the project category coding consists of a project category code and a serial number.

[0026] Furthermore, the project category code consists of English letters; the serial number consists of Arabic numerals.

[0027] Furthermore, in establishing data associations, during project measurement, based on the quality inspection result information of the sub-project / sub-sub-project corresponding to the measurement component code, if the quality inspection is qualified, measurement is allowed; if the quality inspection is unqualified, measurement is prohibited.

[0028] Furthermore, for components with multiple sub-projects / sub-sub-projects, it is not necessary to wait for all sub-projects / sub-sub-projects to pass the quality inspection before measurement. A measurement ratio can be allocated for each sub-project / sub-sub-project, and after each sub-project / sub-sub-project passes the quality inspection, the component is measured according to the allocated ratio.

[0029] The method for generating the core structure tree of the quality cost sheet for highway digital construction management provided by the present invention has the following beneficial effects:

[0030] I. Improve management efficiency and accuracy

[0031] Simplify the management process: By constructing the core structure tree of the quality cost sheet, the originally independent and complex quality inspection and evaluation structure tree and the measurement ledger structure tree are integrated into one, eliminating the cumbersome process of manually establishing the mapping relationship between the two in the past. This enables the quality management and cost management work in highway construction management to be carried out based on the same data structure, reducing a large number of repetitive operations, significantly shortening the management process, and remarkably improving work efficiency.

[0032] Precise data acquisition: The unified coding rule assigns a unique code to each level of the project, just like attaching a unique "label" to various project information. Whether querying the detailed information of a specific component or obtaining the quality inspection and measurement data of a specified sub-project, it can be quickly and accurately located, avoiding confusion and errors in the data search process, and improving the efficiency and accuracy of data acquisition.

[0033] II. Strengthening the synergy between quality management and cost management

[0034] Quality assurance: After establishing data association, project measurement is based on the quality inspection results of sub-projects / sub-sub-projects. Only qualified quality inspections can be measured. This mechanism fundamentally eliminates the situation of measuring unqualified parts, prompting the construction unit to pay more attention to project quality and strictly control the quality during the construction process of each sub-project / sub-sub-project, thus effectively guaranteeing the overall quality of highway projects.

[0035] Precise cost control: The measurement ledger structure tree can be quickly generated according to management needs and can accurately reflect the actual project cost situation. Combining with the sharing of quality inspection data, it can clearly understand the project quality status corresponding to each measurement unit, avoid the increase in rework costs caused by quality problems, achieve precise control of project costs, and effectively prevent cost overruns.

[0036] III. Improving the level of digital management

[0037] Data interconnection and sharing: The seamless connection and data sharing between quality and cost operations break down the data barriers between the previous quality management system and cost management system. Personnel from different departments can obtain the required information in real time on the same data platform. For example, quality management personnel can timely understand measurement data, and cost management personnel can also master the project quality situation, realizing the efficient circulation and full utilization of data, and providing comprehensive and accurate data support for project decision-making.

[0038] Facilitating system integration: The unified structure tree and coding rule facilitate the integration of various highway project management systems. Whether it is the progress management system, material management system or other related systems, they can conduct data interaction and sharing based on the core structure tree of quality and cost sheets and its coding rule, which is convenient for building an all-round and integrated digital management platform for highway projects and improving the overall digital management level of the project.

[0039] IV. Reducing management costs and risks

[0040] Reduction of labor costs: It reduces the workload of manually establishing the mapping relationship of the structure tree, correspondingly reducing the investment in labor costs. At the same time, due to the improvement of data accuracy, it reduces the repetitive labor and error decision-making costs caused by data errors.

[0041] Strengthened risk prevention and control: Timely and accurate quality and cost data can help management personnel discover potential quality problems and cost risks in advance. For example, when the unqualified rate of multiple sub-projects of a certain component is relatively high, the construction plan can be adjusted in a timely manner; if abnormal engineering measurement is found in a certain area, the cause can be quickly investigated and the risks of engineering quality problems and out-of-control costs can be effectively reduced.

[0042] Through constructing a quality and cost single-core structure tree, defining coding rules, implementing mode conversion, and establishing data associations, the present invention simplifies the management process, improves the accuracy of data acquisition, strengthens the coordination of quality and cost management, enhances the digital management level, reduces management costs and risks, and thereby significantly improves the efficiency and quality of digital management of highway projects.

Together with the following specific implementation manners, they are used to explain the present invention, but should not be construed as limiting the present invention. In the drawings:

[0049] The following further details the specific implementation manners of the present invention with reference to the drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the present invention and are not used to limit the present invention.

[0050] In the construction management of highway projects, engineering measurement is carried out according to the smallest measurement unit, and the measurement ledger structure tree is divided according to the engineering entity structure; quality inspection and evaluation are carried out step by step according to sub-projects, sub-divisions, and units, and sub-projects are divided according to construction procedures, processes, or materials.

[0051] To meet the needs of quality inspection assessment and digital management of quality inspection materials, and at the same time meet the needs of engineering measurement and digital management of project cost, the two are organically combined to establish a direct connection relationship between measurement units (i.e., components) and sub-projects. Through the "two-in-one" method, a seamless connection and interconnection between quality inspection data and engineering measurement are realized with the "single-core structure tree" as the carrier.

[0052] Please refer to Figure 1 , the present invention provides a method for generating a single-core structure tree of quality cost for highway digital construction management, including:

[0053] I. Construct a hierarchical structure tree: Decompose the engineering project according to the hierarchy of unit project, sub-project, component, sub-project / sub-sub-project to construct a single-core structure tree of quality cost. As shown in Table 3.

[0054] Table 3 Example of a single-core structure tree of quality cost

[0055]

[0056] In constructing the hierarchical structure tree, unit projects and sub-projects are divided according to the "Highway Engineering Quality Inspection and Assessment Standard" (JTGF80 / 1—2017); components are divided into the smallest measurement units according to the measurement rules of the construction project bill of quantities; sub-projects / sub-sub-projects are divided based on component processes, procedures, materials, etc. according to the "Highway Engineering Quality Inspection and Assessment Standard" (JTG F80 / 1—2017).

[0057] Sub-projects / sub-sub-projects refer to the sub-projects included in the components. If there are multiple identical sub-projects under the same sub-project (such as the sub-project "Reinforcement processing and installation" corresponding to multiple identical sub-projects under the sub-project "Foundation and lower structure (0# abutment)" in the above table), then each identical sub-project is regarded as a sub-sub-project, and the set of each identical sub-sub-project is a sub-project (such as the sub-project corresponding to the sub-project "Foundation and lower structure (0# abutment)" in the above table is "Reinforcement processing and installation, bored cast-in-place pile, abutment cap, bearing pad stone, ear back wall, backfill behind abutment"). The reason for the concept of sub-project / sub-sub-project is that engineering measurement must be based on qualified quality inspection, but quality assessment does not need to be carried out for each sub-sub-project, and only the sub-sub-projects need to be combined into a sub-project for one-time assessment. Sub-projects / sub-sub-projects are the bottom layer of the quality inspection assessment structure tree and are directly associated with the components in the single-core structure tree to achieve seamless connection between quality inspection and measurement.

[0058] II. Define coding rules: Based on the "Highway Engineering Quality Inspection and Assessment Standard" (JTG F80 / 1—2017) and the measurement rules of the bill of quantities, formulate unified coding rules to assign unique codes to each level of the project. The coding separates the project information of each level through specified symbols.

[0059] Combined with the "Quality Inspection and Evaluation Standards for Highway Engineering" (JTG F80 / 1—2017) and the measurement rules of the bill of quantities for highway engineering, establish the engineering division and coding standards for the core structure tree of the quality cost list, providing a basis for the application of the core structure tree of the quality cost list, as shown in Example Table 4.

[0060] Example Table 4 Engineering Division and Coding Standards for the Core Structure Tree of the Quality Cost List

[0061]

[0062] In the above table, the "Identification" column includes five types of engineering categories: unit engineering, sub - division engineering, component, sub - item engineering, and sub - sub - item engineering. When there are no sub - item engineering / sub - sub - item engineering categories under the engineering category "component", it means that this type of component is not included in the quality inspection and evaluation scope.

[0063] The structure tree coding is expressed in a tree - like structure of "unit engineering → sub - division engineering → sub - sub - division engineering (if any) → component → sub - item engineering / sub - sub - item engineering". The codes of unit engineering, sub - division engineering / sub - sub - division engineering, and component are separated by "." (half - angle), and the codes between component and sub - item engineering / sub - sub - item engineering are separated by ":" (half - angle). The coding form is as Figure 2 。

[0064] The structure tree coding is a coding system that identifies the engineering levels in the entire core structure tree of the quality cost list. It is constructed following specified rules to clearly present the hierarchical relationship of the projects. The engineering category coding is an important part of the structure tree coding, which is used to clarify the category to which each level of engineering belongs.

[0065] The engineering category coding consists of an engineering category code and a serial number. The engineering category code is composed of two capital English letters, representing the engineering category; the serial number is composed of 3 Arabic numerals, representing the sequence of the engineering category (the nth, the nth place, the nth number...).

[0066] Coding Example 1:

[0067] QL001.JC000.ZJ001:GJ001

[0068] Meaning: Bridge (Bridge No. 001) (unit engineering) - Foundation and Sub - structure (Pier No. 0) (sub - division engineering) - Pile Foundation (No. 1) (component) - Steel Bar Processing and Installation (sub - item engineering).

[0069] Coding Example 2:

[0070] SD001.CQ001.EC001:GJ001

[0071] Meaning: Tunnel (Tunnel No. 001) (unit project) - Tunnel Lining (Paragraph No. 001) (sub - project) - Secondary Lining (Section No. 1) (component) - Steel Bar Processing and Installation (sub - item project).

[0072] III. Realize mode conversion: When conducting quality management operations, convert the core structure tree of the quality and cost list into a quality inspection and assessment structure tree; when conducting cost management operations, convert the core structure tree of the quality and cost list into a measurement ledger structure tree.

[0073] 1. When conducting quality management operations, hide the component level, aggregate the sub - sub - item projects under the same sub - project into sub - item projects, and at the same time attach the component information to the sub - sub - item project information, then the quality inspection and assessment structure tree can be formed. An example is shown in Table 5.

[0074] 2. When conducting cost management operations, hide the sub - item project / sub - sub - item project level and directly display to the component level, then the measurement ledger structure tree can be formed. An example is shown in Table 6.

[0075] Table 5 Quality Inspection and Assessment Structure Tree Formed after Hiding Measurement Units

[0076]

[0077]

[0078] Table 6 Measurement Ledger Structure Tree Formed after Hiding Sub - item Projects / Sub - sub - item Projects

[0079]

[0080] In the application system, according to the needs of the application scenario, based on the core structure tree of the quality and cost list, perform the application mode conversion of the quality inspection and assessment structure tree and the measurement ledger structure tree.

[0081] ① Convert the single - core structure tree into a quality inspection and assessment structure tree

[0082] When conducting quality inspection and assessment, it is based on the quality inspection and assessment structure tree.

[0083] Hide the component level, aggregate the sub - sub - item projects into sub - item projects, and at the same time attach the component information to the sub - sub - item information (for clarity of the project location), then the quality inspection and assessment structure tree can be obtained. An example is shown in Figure 3 .

[0084] ② Convert the single - core structure tree into a measurement ledger structure tree

[0085] Engineering measurement, cost analysis, etc. are based on the measurement ledger structure tree.

[0086] Hide the sub - item project / sub - sub - item project, then the measurement ledger structure tree can be obtained. An example is shown in Figure 4 .

[0087] Based on the quality cost list core structure tree, sub - sub - item projects can be aggregated into sub - item projects by hiding components, and component information can be attached to sub - sub - item information to form a quality inspection and evaluation structure tree. Also, a measurement ledger structure tree can be formed by hiding sub - item projects / sub - sub - item projects, meeting the requirements of quality management and cost management at the same time, seamlessly connecting quality inspection and project measurement, realizing the intercommunication of quality and cost services and data sharing, and greatly improving the digital management level and efficiency of the project.

[0088] IV. Establish data association: Associate the quality inspection results of sub - item projects / sub - sub - item projects through component codes, and determine whether measurement can be carried out according to the quality inspection results to achieve the sharing of measurement and quality inspection data.

[0089] During project measurement, based on the quality inspection result information of the sub - item project / sub - sub - item project corresponding to the measurement component code (i.e., the sub - item project / sub - sub - item project after the component code ":"). If the quality inspection is qualified, measurement is allowed; if the quality inspection is unqualified, measurement is prohibited. For components with multiple sub - item projects / sub - sub - item projects, when necessary, a measurement ratio can be allocated for each sub - item project / sub - sub - item project, and measurement is carried out according to the allocated ratio after the quality inspection is qualified.

[0090] In the construction management of highway projects, quality inspection and project measurement are two key links. In the past, there was a lack of effective data association between them, resulting in low management efficiency. However, in this application, the technical means of "establishing data association" closely links the quality inspection results of sub - item projects and sub - sub - item projects with project measurement through the key link of component codes.

[0091] The component code is the core identifier of the entire data association system. Each component code corresponds to a unique component, and the coding part after its ":" precisely points to the relevant sub - item projects and sub - sub - item projects. During actual project measurement operations, the system will quickly retrieve and obtain the corresponding quality inspection result information of the sub - item project / sub - sub - item project based on the component code. If the quality inspection result shows qualified, it means that this part of the project meets the quality standards and meets the measurement conditions, and then measurement work is allowed. On the contrary, if the quality inspection is unqualified, it indicates that there are problems with the project quality. At this time, measurement is prohibited, effectively avoiding measurement and payment for unqualified projects and ensuring the seriousness of project quality and cost management.

[0092] For components that include multiple sub-projects / sub-sub-projects, it is not necessary for all sub-projects / sub-sub-projects to pass the quality inspection before measurement. When necessary, the measurement ratio can be allocated according to the processes and importance of each sub-project / sub-sub-project. The setting of this ratio is based on the actual engineering situation and management requirements. For example, when the 7-day curing strength grade of concrete meets the corresponding requirements, 70% is measured, and when the 28-day curing strength grade meets the requirements, the remaining 30% is measured. After each sub-project / sub-sub-project passes the quality inspection, the components are measured according to the pre-allocated measurement ratio, making the measurement results more scientific and reasonable, and accurately reflecting the actual engineering value.

[0093] The method for generating the core structure tree of the quality cost list for highway digital construction management provided by the present invention has the following beneficial effects:

[0094] I. Improve management efficiency and accuracy

[0095] Simplify the management process: By constructing the core structure tree of the quality cost list, the originally independent and complex quality inspection evaluation structure tree and measurement ledger structure tree are integrated into one, eliminating the cumbersome process of manually establishing the mapping relationship between the two in the past. This enables the quality control and cost control work in highway construction management to be carried out based on the same data structure, reducing a large number of repetitive operations, significantly shortening the management process, and remarkably improving work efficiency.

[0096] Accurate data acquisition: The unified coding rule assigns a unique code to each level of the project, just like attaching a unique "label" to various project information. Whether querying the measurement information of a specific component or obtaining the quality inspection information of a specified sub-project, it can be quickly and accurately located, avoiding chaos and errors in the data search process, and improving the efficiency and accuracy of data acquisition.

[0097] II. Strengthen the coordination between quality management and cost management

[0098] Quality assurance: After establishing the data association, project measurement is based on the quality inspection results of sub-projects and sub-sub-projects. Only those that pass the quality inspection can be measured. This mechanism fundamentally eliminates the situation of measuring parts with unqualified quality, prompting the construction unit to pay more attention to project quality and strictly control the quality in the construction process of each sub-project and sub-sub-project, thus effectively guaranteeing the overall quality of highway projects.

[0099] Accurate cost control: The measurement ledger structure tree can be quickly generated according to management requirements and can accurately reflect the actual project cost situation. Combined with the sharing of quality inspection data, it can clearly understand the project quality status corresponding to each measurement unit, avoid the increase in rework costs caused by quality problems, achieve accurate control of project costs, and effectively prevent cost overruns.

[0100] III. Improving the level of digital management

[0101] Data interconnection and sharing: The seamless connection and data sharing between quality and cost management operations have broken down the data barriers between the previous quality management system and cost management system. Personnel from different departments can obtain the required information in real time on the same data platform. For example, quality management personnel can promptly understand measurement data, and cost management personnel can also grasp the project quality situation, achieving efficient data circulation and full utilization, and providing comprehensive and accurate data support for project decision-making.

[0102] Facilitating system integration: The unified structure tree and coding rules facilitate the integration of various highway project management systems. Whether it is the progress management system, material management system, or other related systems, they can conduct data interaction and sharing based on the core structure tree of the quality-cost form and its coding rules, facilitating the construction of an all-round and integrated digital management platform for highway projects and enhancing the overall digital management level of the project.

[0103] IV. Reducing management costs and risks

[0104] Reduction of labor costs: The workload of manually establishing the mapping relationship of the structure tree is reduced, correspondingly reducing the investment in labor costs. At the same time, due to the improvement of data accuracy, the repetitive labor and error decision-making costs caused by data errors are reduced.

[0105] Enhanced risk prevention and control: Timely and accurate quality and cost data can help management personnel discover potential quality problems and cost risks in advance. For example, when the unqualified rate of multiple sub-project quality inspections of a certain component is relatively high, the construction plan can be adjusted in a timely manner; if abnormal project measurement is found in a certain area, the cause can be quickly investigated, effectively reducing the project quality risk and the risk of cost out of control.

[0106] Through constructing the core structure tree of the quality-cost form, defining coding rules, implementing mode conversion, and establishing data associations, the present invention simplifies the management process, improves the accuracy of data acquisition, strengthens the coordination between quality and cost management, enhances the level of digital management, reduces management costs and risks, and thus significantly improves the efficiency and quality of digital management of highway projects.
