[0024] In an alternative embodiment, the contract management subsystem further comprises:

[0025] The construction list module is connected with the contract coding module, and is configured to obtain a construction management contract, and associate the construction management contract with a construction list item in a construction drawing list using the engineering quantity list code; wherein the construction management contract and the construction drawing list each contain the engineering quantity list code, and the construction list item corresponds to the engineering quantity list code in a one-to-one manner.

[0038] The progress monitoring module is used to obtain real-time project progress information and monitor the real-time project progress information based on the unit project's measurement and certification form.

[0039] The quality inspection module is used to associate the inspection code corresponding to the preset inspection information with the unit code, and to use the association relationship between the inspection code and the unit code to inspect the unit project and obtain the quality inspection result.

[0040] This embodiment provides an integrated management system for large-scale engineering projects. By monitoring and controlling project costs, progress, and quality through measurement and certification forms for unit projects, it achieves "atomic"-level coordination and unification of progress, quality, and cost in large-scale projects. This forms a complete system for comprehensive control of project costs, progress, and quality, thereby achieving the goal of controlling and managing information throughout the entire process of large-scale projects.

[0041] In one alternative implementation, the cost control module is further configured to compare the project budget with the actual project costs, and predict the project costs based on the comparison results to obtain the project forecast cost.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0060] Taking the Three Gorges Dam project as an example, the large-scale integrated management information system adopts the Three Gorges Project Management System (TGPMS). The development and application of the TGPMS is a long-term and arduous systems engineering project. Overcoming technical and management challenges during its construction, TGPMS is a high-tech project combining modern computer technology, communication technology, database technology, office automation technology, multimedia technology, and modern management science. TGPMS differs from general information systems. Ordinary information systems process mostly unstructured data, meaning that the information is not strongly correlated in time or logic and does not require prediction or control of a predetermined goal.

[0061] The engineering construction management system uses information engineering methods to transform abstract management concepts, complex project management rules, and massive amounts of information data into operable, compliant, inspectable, and controllable computer logic operations, judgments, transfers, and calls through a database management system. This transforms scientific management into a human-machine integrated computer management system.

[0062] TGPMS covers all aspects of the Three Gorges Project construction, permeating all departments including contractors, supervisors, designers, suppliers, and owners. To achieve efficient, unified, standardized, and coordinated management and control of the Three Gorges Project's planning, schedule, cost, quality, funding, engineering technology and documentation, material and equipment procurement, construction, and contract management, and to form an information system encompassing the implementation, management, and decision-making levels of the Three Gorges Project, as well as external communications at all levels, the system requires strong integration. Only in this way can the goal of achieving comprehensive information control and management of the entire Three Gorges Project process be realized through efficient and unified information management.

[0063] The Three Gorges Dam project is characterized by large investments, long construction periods, and geographically dispersed locations. Furthermore, in the field of project management, its business relationships are not as clearly structured as those in the cyclical management of production processes. These characteristics of the Three Gorges Dam project place higher demands on the design, development, and implementation of the TGPMS system model, requiring it to meet existing business management needs while adapting to the continuous expansion of future business operations.

[0064] This application provides a large-scale engineering integrated management system, which enables integrated management of large-scale engineering construction.

[0065] This embodiment provides a large-scale integrated engineering management system, as shown in Figure 1. The system includes:

[0066] The preliminary estimate subsystem 101 is used to acquire target project information, perform multi-level classification and encoding processing on the target project information, and obtain the preliminary estimate code.

[0067] The contract management subsystem 102 is connected to the budget estimate subsystem 101. It is used to decompose the target project information, generate multiple project contracts, and associate the multiple project contracts with the budget estimate code.

[0068] The construction control subsystem 103 is connected to the contract management subsystem 102. It is used to break down the engineering contract into unit projects, encode the unit projects to obtain unit codes, and associate the engineering quantity data corresponding to the unit projects with the preset construction drawing list.

[0069] Specifically, the construction control subsystem 103 associates unit projects with construction bill of quantities (BOQ) codes based on unit codes and BOQ codes, thereby completing the construction acceptance and settlement of unit projects. The specific processing method and working principle are as follows:

[0070] (1) The construction management contract and the construction drawing list are consistent at a certain level (such as sub-item works), but the details of each can be different at that level, and the total amount can also be different; the construction drawing list can be formed in batches; when the construction management contract is established, the items of the construction management contract at that level are construction management settlement items (i.e., the bottom items of the construction management contract), while the items of the construction drawing list at that level are summary items.

[0071] By employing algorithms such as year-on-year settlement of construction management contract progress and digital models for project delivery, the system links multiple dimensions of project information, including budget, quality, progress, measurement, contract payment, expense reimbursement, and financial settlement. This ensures the correlation and continuous traceability of project estimates, budgets, and settlement data, and is suitable for the integrated management needs of large-scale projects in various sectors such as hydropower, pumped storage, environmental water affairs, and new infrastructure.

[0072] (2) The total amount of the construction drawing bill of quantities at this level cannot be changed once settlement occurs, but new items can be added; the unit price of the added new items is set to zero; therefore, all calculation items of the unit project should be included in the construction drawing bill of quantities.

[0073] (3) The sum of the quantities of a unit project under a certain construction drawing list item shall not exceed the preset quantities of the construction drawing list item; when measuring a unit project, if the actual quantities are less than the designed quantities of the unit project, the actual quantities shall be used for calculation; if the actual quantities are greater than the designed quantities of the unit project, the actual designed quantities shall be used for calculation.

[0074] The joint control subsystem 104 is connected to the contract management subsystem 102 and the construction control subsystem 103. It is used to generate measurement and verification forms based on the relationship between the engineering contract and the budget code, as well as the relationship between the engineering quantity data and the preset construction drawing list. Based on the measurement and verification forms, it performs joint control over the engineering cost, engineering progress and engineering quality, so as to carry out integrated management of large-scale projects.

[0075] Specifically, in the management of large-scale projects, due to their inherent complexity and the lack of effective management platform support, the control of schedule, quality, and cost has long been difficult to achieve at the "atomic" level. This results in the inability of cost, schedule, and quality to maintain synchronization in time and quantity, which greatly affects the effectiveness and timeliness of project management personnel's decision-making. Therefore, during the advancement or acceptance of engineering projects, a unified visa model, namely the measurement visa form, can be used to simultaneously control project costs and schedule, and ensure that project quality meets requirements, thereby achieving "atomic" level coordination and unity among project schedule, project quality, and project cost.

[0076] This embodiment provides an integrated management system for large-scale engineering projects. Through a budgeting subsystem, a contract management subsystem, a construction control subsystem, and a joint control subsystem, an information system is formed that connects the implementation layer, management layer, and decision-making layer of large-scale engineering projects. This system enables integrated management of large-scale engineering projects, improves the overall management level of large-scale engineering projects, and provides the decision-making layer with accurate and timely analytical and decision-making information. Thus, it achieves the goal of controlling and managing information throughout the entire process and all aspects of large-scale engineering projects.

[0077] In some alternative implementations, the budgeting subsystem 101 includes:

[0078] The hierarchical module 1011 is used to perform multi-level classification processing on the budget items in the target project information to obtain multi-level budget data.

[0079] Specifically, the hierarchical module 1011 is used to classify the budget items into multiple levels, forming various levels with certain logical relationships, and each level is further classified according to project management rules; among them, the budget items are the investment information of the current engineering project, including the budget content of each part, link and level of the current engineering project, as shown in Table 1 below:

[0080] Table 1:

[0081] The model building module 1012 is used to obtain encoding requirements and generate an encoding template matrix based on the preset hierarchical classification definition data.

[0082] Specifically, based on the definitions or descriptions of each level and category, a general coding template matrix is ​​formed to meet different coding needs. Based on the coding template matrix, project-related coding, such as budget coding and contract coding, is carried out to provide a foundation for subsequent data association and integrated management.

[0083] Optionally, the hierarchical code structure in the encoding template matrix consists of different parts, each determined by a length and a delimiter with a mask format. The hierarchical code structure includes: encoding name, hierarchical type, hierarchical code, etc. The encoding name is defined as a brief description of the hierarchical structure code; the hierarchical type code is defined as the type code of a certain type of hierarchical structure code. In the TGPMS system, hierarchical codes can be divided into several types. Steel, wood, and cement all belong to the material category, and their hierarchical structure code type is COMM (communication); the hierarchical code is defined as the encoding of a certain type of hierarchical structure code, such as the encoding of steel as 1, wood as 2, and cement as 4; the combination of the hierarchical type code and the hierarchical code can uniquely determine the encoding of a certain type of hierarchical structure code.

[0084] The preliminary calculation coding module 1013 is connected to the hierarchical module 1011 and the model building module 1012. It is used to encode multi-level preliminary calculation data based on the coding template matrix to generate preliminary calculation codes.

[0085] Specifically, the above-mentioned coding template matrix is ​​used as the coding model. According to a certain order (such as letters, numbers, etc.), corresponding codes are generated for each level and category of preliminary estimate data. At the same time, each code corresponds to a description, which is the same as the detailed description in the engineering contract. Finally, multiple preliminary estimate codes are formed, as shown in the table below.

[0086] Table 2:

[0087] Optionally, the preliminary cost code is a multi-digit combination code, which is divided into several segments. Depending on different engineering requirements, different numbers and structures of segment sequences are matched. The preliminary cost code is a coding sequence formed by independent code combinations of different properties, and the data of this coding sequence is subsequently used for statistical analysis.

[0088] Optionally, the budget coding structure is: budget grading code, WBS (construction index code), and CWP code. For example, the budget code is AA-MMM-BBCCDDEEFFGG-HHHH, where AA (budget grading code) represents a sub-project, with a format of two digits and mixed characters, which can be user-defined; WBS (construction index code) is used to mark the work type of the contract project in the detailed part; CWP code is a three-digit number that can be user-defined. CWP code represents the area division of a sub-project. This code links design, procurement, installation, etc. Each CWP has its own independent scope, budget, and plan. The above CWPs control each stage of the project, and each divided area is unique and non-overlapping.

[0089] This embodiment provides a large-scale integrated engineering management system that performs multi-level classification of budget projects, enabling detailed hierarchical and classification of each sub-project within the budget project, forming a complete and clear data system for the budget project. Furthermore, by using a coding template matrix to encode the multi-level budget data, accurate coding of the multi-level budget data is achieved, laying the foundation for monitoring the subsequent engineering construction process.

[0090] In some optional implementations, the budget coding module 1013 is also used to obtain the bill of quantities code and associate the budget code with the bill of quantities code according to a preset association rule; wherein the budget code and the bill of quantities code correspond one-to-one.

[0091] This embodiment provides a large-scale integrated management system for engineering projects, which associates the preliminary cost code with the bill of quantities code, laying the foundation for subsequent engineering cost management.

[0092] In some alternative implementations, the contract management subsystem 102 includes:

[0093] The contract coding module 1021 is used to decompose multi-level budget data into multiple engineering contracts, and to encode the multiple engineering contracts using a preset contract coding model to generate contract codes.

[0094] Specifically, each contract code corresponds to one engineering contract, and each contract code corresponds to multiple BOQ codes. Each bill of quantities item corresponds to a unique preliminary estimate code, as shown in Table 3 below.

[0095] Table 3:

[0096] The association module 1022 is connected to the contract coding module 1021 and is used to associate the budget code with the engineering contract based on the contract code.

[0097] Specifically, using the descriptions corresponding to each level, the budget estimate code is associated with the BOQ code in one or more contracts. By reviewing and controlling the budget estimate on the budget estimate code, the execution code (including cost control allocation, plan execution package, etc.) is linked to the control budget estimate for generating reports. The control budget estimate includes budget estimate quantity, budget estimate unit price, unit price, and budget estimate amount. The budget estimate quantity represents the currently approved control budget estimate quantity and has a budget estimate code. When the quantity control flag is set to an asterisk, approved detailed budget estimates with the same budget estimate code are summarized into the budget estimate quantity. The budget estimate unit price represents the average unit price. The unit price equals the budget estimate amount / quantity. The budget estimate amount represents the currently approved control budget estimate amount and has a budget estimate code.

[0098] This embodiment provides a large-scale integrated management system for engineering projects. Based on contract codes, it associates budget codes with engineering contracts, enabling each engineering contract to correspond to multi-level budget data, thus laying the foundation for subsequent monitoring of engineering costs.

[0099] In some alternative implementations, the contract management subsystem 102 further includes:

[0100] The construction list module 1023, connected to the contract coding module 1021, is used to obtain the construction management contract and associate the construction management contract with the construction list items in the construction drawing list using the bill of quantities code; wherein, the construction management contract and the construction drawing list each contain bill of quantities codes, and the construction list items correspond one-to-one with the bill of quantities codes.

[0101] Specifically, the bill of quantities module 1023 is used to preprocess the construction management contract and use the bill of quantities code to identify the construction list items at the same level as the preprocessed construction management contract, and associate the preprocessed construction management contract with the construction list items.

[0102] Optionally, as shown in Table 4 below, the EPC (Engineering Procurement Construction) contract in the construction management contract is output. The actual input EPC contract is preprocessed to obtain an EPC contract with different hierarchical sorting methods, as shown in Table 5 below. The information in the same row corresponding to the same BOQ code has the same level in both tables.

[0103] Table 4:

[0104] Table 5:

[0105] As shown in Tables 4 and 5 above, 01, 0101, 0102, 0103, 0104, and 02 in the BOQ code represent different levels, and the input EPC contract is processed according to this level.

[0106] Optionally, the construction management contract and the construction drawing list can be consistent at a certain level. The items in the construction management contract at this level are construction management settlement items (i.e., the bottom-level items of the construction management contract), while the items in the construction drawing list at this level are summary items. The sub-items and summaries at this level can be different.

[0107] For example, establish the association between the pre-processed EPC contract and the bill of quantities items, and enter the bill of quantities items at this level into the EPC contract. The bill of quantities is shown in Table 6 below.

[0108] Table 6:

[0109] In Tables 5 and 6, the items are Pile Foundation Engineering 1 and Pile Foundation Engineering 2. The EPC contract corresponding to Table 5 and the construction drawing list corresponding to Table 6 are consistent at the levels of 010 and 012, but the total amount of the sub-items under their respective levels is different.

[0110] This embodiment provides a large-scale integrated management system for engineering projects. By using bill of quantities coding, the construction management contract is associated with the construction list items in the construction drawings, clarifying the corresponding construction list items in the construction management contract and laying the foundation for subsequent construction control.

[0111] In some alternative implementations, the construction control subsystem 103 includes:

[0112] The project splitting module 1031 is used to split the project in the project contract into multiple levels of projects, determine the unit projects, and encode the unit projects to generate unit codes; wherein, the unit project is the lowest level project; multiple unit codes correspond to one contract code.

[0113] Specifically, based on the specific content of the project and the various levels of content set and divided by the manager, different levels are classified, planned, and coded. The current project is divided into multiple levels, with the content of each level decreasing sequentially. Each level includes all the content of the next level, and the lowest level is the unit project. At the same time, the unit projects are coded. Multiple unit projects correspond to one project contract, that is, multiple unit project codes correspond to one project contract code.

[0114] Optionally, the lowest level of the project is a unit project. For example, the project is divided into unit projects, sub-projects, sub-items and unit projects, and each level corresponds to a coding rule. For example, 11 is a unit project, 001 is a sub-project, 01 is a sub-item and 0001 is a unit project. Then the current unit project code is 11001010001.

[0115] The unit project association module 1032 is connected to the project splitting module 1031 and is used to associate the engineering quantity data corresponding to the unit project with the engineering quantity list code corresponding to the construction list item; wherein, the unit code and the engineering quantity list code correspond one-to-one.

[0116] Among them, the sum of the quantity data of a unit project in the bill of quantities is less than or equal to the rated quantity data of the bill of quantities.

[0117] Specifically, after the engineering unit decomposition and construction drawing list information have been completed, the quantities of the engineering cost items in the construction drawing list need to be allocated to the associated unit projects according to the construction drawings and design calculations. Then, when settling the construction management contract, the completed construction drawing budget amount can be calculated based on the quantities and budget unit prices of the corresponding items in the construction drawing list after the unit projects have passed acceptance. At the same time, the quantities allocated to the associated unit projects are the design quantities, which can be used for control of visa measurement.

[0118] For example, when the unit project is an inspection batch project, the design quantity of the inspection batch project is associated with the construction bill of quantities item, as shown in Table 7 below.

[0119] Table 7:

[0120] The unit project settlement module 1033, connected to the unit project association module 1032, is used to calculate the settlement amount of the construction management contract based on the project quantity data.

[0121] Specifically, the settlement amount of the construction management contract is calculated based on the quantity and unit price of the corresponding items in the construction drawing list after the unit project has passed acceptance. The completed construction drawing budget amount is then calculated and settled proportionally with the corresponding itemized project cost of the construction management contract. The completed construction drawing budget amount is the intermediate measurement amount for the settlement of the construction management contract. It is an important basis for the construction unit to submit the progress settlement application for the construction management contract and for the owner to make contract payments. After the intermediate measurement amount is calculated, the settlement amount of the BOQ item in the construction management contract with the cost occurrence type "automatic contract cost generated by measurement visa" is automatically calculated based on the approved measurement visa document using the progress proportional settlement method.

[0122] For example, based on the association of the design quantities of the inspection batch project with the construction bill of quantities items in Table 7, the calculation process of the intermediate measurement amount in the construction drawing bill of quantities is shown in Table 8 below, and the intermediate measurement results in the construction drawing bill of quantities are shown in Table 9 below.

[0123] Table 8:

[0124] Table 9:

[0125] As shown in Table 8, the intermediate measurement amounts for the "Excavation" item in the bill of quantities are 300 and 300 respectively. Furthermore, as shown in Table 9, the intermediate measurement amount for the "Excavation" item in the construction management contract corresponding to the bill of quantities is 600. The calculation process for the intermediate measurement amounts for the "Pile Driving" and "Concrete Pouring" items in the construction management contract is the same as that for the "Excavation" item.

[0126] This embodiment provides a large-scale integrated management system for engineering projects, which associates the engineering quantity data corresponding to unit projects with the engineering quantity list codes corresponding to the construction list items, and calculates the settlement amount of the construction management contract based on the engineering quantity data, thus clarifying the engineering quantity and settlement amount of unit projects and realizing precise management of the engineering quantity and settlement amount of unit projects.

[0127] In some alternative implementations, the joint control subsystem 104 includes:

[0128] The measurement certificate generation module 1041 is used to associate unit projects with bill of quantities codes based on unit codes, and integrate preset project progress information and preset inspection information to generate measurement certificate forms for unit projects.

[0129] Specifically, the measurement visa generation module 1041 associates one or more different BOQ codes based on the decomposition of the unit project and the unit code.

[0130] The cost control module 1042 is used to obtain the actual amount of the project, determine the project budget based on the relationship between the budget code and the bill of quantities code, and manage and control the actual amount of the project based on the project budget.

[0131] Specifically, the cost control module establishes a preliminary project estimate and tracks the contract costs and actual project costs of the construction management contract. Based on the preliminary project estimate, it establishes a control budget and forecasts the final cost. The preliminary project estimate is derived from the detailed estimate, which includes quantities, contract unit prices, and man-hours, thus establishing the scope required for the entire project.

[0132] Optionally, in order to ensure the effectiveness of the cost control module, all costs in the construction project must be reflected in the form of contracts or virtual contracts. The bill of quantities (BOQ) of each contract is associated with the cost control code (usually the preliminary estimate code), thereby effectively managing and controlling the project funds.

[0133] The progress monitoring module 1043 is used to acquire real-time project progress information and monitor the real-time project progress information based on the unit project's measurement and certification form.

[0134] Specifically, the progress module is used to record the daily real-time project progress information. The real-time project progress information mainly includes: date, contract code, project, project location, detailed location, planned quantity and actual quantity, etc. It reflects the cumulative quantity completed so far in the current period and the percentage of the cumulative quantity completed to the planned quantity completed through the daily planned quantity completed and the actual quantity completed.

[0135] The quality inspection module 1044 is used to associate the inspection code corresponding to the preset inspection information with the unit code, and to use the association relationship between the inspection code and the unit code to inspect the unit project and obtain the quality inspection result.

[0136] Specifically, based on contract codes and unit codes, the inspection codes are associated with the unit codes, and the quality inspection of each inspection item is carried out according to the preset inspection standards.

[0137] This embodiment provides an integrated management system for large-scale engineering projects. By monitoring and controlling project costs, progress, and quality through measurement and certification forms for unit projects, it achieves "atomic"-level coordination and unification of progress, quality, and cost in large-scale projects. This forms a complete system for comprehensive control of project costs, progress, and quality, thereby achieving the goal of controlling and managing information throughout the entire process of large-scale projects.

[0138] In some optional implementations, the cost control module 1042 is also used to compare the project budget with the actual project cost, and to predict the project cost based on the comparison results, thereby obtaining the project forecast cost.

[0139] This embodiment provides a large-scale integrated management system for engineering projects. By comparing the project budget with the actual project costs, the system predicts project costs and achieves reasonable prediction and control of the costs of subsequent construction projects based on the actual project costs.

[0140] In some optional implementations, the progress monitoring module 1043 is specifically used to generate a percentage of project progress completion based on real-time project progress information and preset project progress information, and to manage the real-time project progress information based on the percentage of project progress completion.

[0141] Specifically, by comparing the actual completed workload (i.e., real-time project progress information) and costs (i.e., actual project expenditures) with the planned workload and costs, performance is measured in monetary terms, and project progress and costs are monitored and analyzed based on quantitative indicators of project performance.

[0142] This embodiment provides a large-scale integrated engineering management system that enables reasonable management of real-time engineering progress information by using the percentage of engineering progress completed.

[0143] In some optional implementations, the progress monitoring module 1043 is also used to encode the preset project progress information to obtain the construction progress plan code, and associate the unit code with the construction progress plan code to obtain the unit project progress information.

[0144] Specifically, the unit codes corresponding to each BOQ item in the construction management contract are associated with the construction schedule code, so that the unit codes correspond to the progress information of each unit project.

[0145] Optionally, the unit project progress information includes the following: Location code: The construction location of the contract project, for example, using the budget classification code in D3105 (Construction location of the contract project, i.e., user-defined budget item) to mark the location; Detailed location: The detailed construction location of the contract project, such as the code data defined in D9079 (Detailed construction location of the contract project, i.e., user-defined budget item); Occurrence date: The date on which the daily completion quantity is to be filled in; Unit: The unit of measurement for the work type is the input WBS code; Daily completed work quantity: The daily completed work quantity of the contract project under the detailed location, with the work type being the input WBS code; Daily planned work quantity: The daily planned work quantity of the contract project under the detailed location, with the work type being the input WBS code.

[0146] This embodiment provides a large-scale integrated management system for engineering projects. By associating unit codes with construction schedule codes, unit project progress information is obtained, providing reference progress information for the construction progress of unit projects. Decision-makers can control the progress of unit projects in real time based on this progress information.

[0147] The following specific example illustrates the working steps of a large-scale engineering integrated management system.

[0148] Example 1:

[0149] As shown in Figure 2, the working steps of a large-scale engineering integrated management system include the following stages:

[0150] During the feasibility study phase, an investment plan is developed based on the current project budget, which estimates the investment required for a certain amount of work. For complex and large-scale projects, the investment plan is further adjusted based on analysis of contract unit prices and price difference indices at different times. This allows for cost control through the amount of work completed and the contract unit prices in the budget, ensuring cost traceability.

[0151] During the bidding and design phase, the project quantities are broken down based on the budget estimate, forming a "contract + BOQ" model, which is decomposed into contract code + BOQ code to obtain the bill of quantities. Subsequently, the bill of quantities is linked and coupled with the investment plan through the payment process of the current project. At the same time, this payment process is also affected by the analysis of the contract unit price and the price difference index at different times.

[0152] During the bidding and design phase, the functions of complex and large-scale engineering projects are decomposed into smaller modules and coupled together, while strict management and quality control are carried out.

[0153] During the detailed construction drawing stage, the current project is decomposed into multiple unit projects, which are then coupled with the contract from the bidding and design stage through BOQ (Bill of Quantities). For complex and large-scale projects at different bidding and design stages, the detailed construction drawing stage is controlled through periodic coupling and linkage relationships at multiple granular levels of decomposition.

[0154] During the detailed construction drawing stage, a quality assessment is conducted for each unit project after the current project is decomposed to determine whether its quality is qualified. That is, the completion of the work volume with the quality qualification of each unit project as a constraint is taken as the qualified progress of the project. Among them, quality management stipulates the quality standards of the project, defines the inspection indicators of unit projects and construction procedures, and controls the construction quality.

[0155] During the detailed construction drawing phase, it is necessary to consider the collaboration and coordination among multiple organizations; at the same time, it is also necessary to consider the supply of materials to ensure the smooth progress of the project.

[0156] In addition, based on the design details and quality assessment results, the corresponding measurement certificates for each unit project are obtained. Subsequently, a progress report is generated based on all measurement certificates. Finally, payment control is carried out based on the progress report and other data.

[0157] It can be seen that the payment process is controlled by multiple factors in the feasibility study, bidding and design, and construction detailing stages, namely, the joint control of cost, schedule, and quality: schedule is measured and controlled by introducing earned value (EV) and price difference; investment costs are calculated through BOQ (Bill of Quantities) in the bidding stage, and quality is assessed through quality constraints to control and manage the quality of the construction process and main materials; schedule measurement, investment cost calculation, and quality assessment are all applied to each unit project; at the unit project level of the current project, contract settlement is controlled through quantity measurement and verification management of unit projects; therefore, once the quality assessment of a unit project is passed, the actual completion of the project schedule and investment plan can be tracked.

[0158] In summary, based on cost breakdown, contract breakdown, schedule breakdown, design drawings, and quality control units, comprehensive coordination and management of cost, schedule, and quality are achieved. Utilizing various project forecasting methods, timely and effective monitoring and forecasting of project cost, schedule, quality, and financial status are conducted, improving the accuracy and scientific nature of decision-making and effectively ensuring the achievement of the three major control objectives of project construction cost, schedule, and quality. Furthermore, changes in measurement approval quantities are simultaneously reflected in schedule and cost, while quality assessment determines whether measurement approvals can continue for a particular unit of work, thus fully realizing the linkage between schedule, quality, and cost.

[0159] Furthermore, when applying the aforementioned integrated management system for large-scale engineering projects to TGPMS, all parties involved in the project can perform real-time analysis, processing, and monitoring of various data, thereby achieving better project management. For example, in cost control, before using TGPMS, information on actual project costs could not be accurately and promptly reflected, easily leading to errors in contract settlement, such as overpayment, underpayment, or delayed settlement. This not only negatively impacted financial management but could also leave behind some difficult-to-handle economic issues during project completion and acceptance. After using TGPMS, every item in the contract has a predicted value. All payment information must be entered into the system and verified before settlement. Once the system detects that the value exceeds the predicted value, it will issue an alarm, allowing managers to focus their attention on these items, promptly handle the corresponding issues, or trace the problem, ultimately achieving the goal of cost control.

[0160] The goal of the hydropower project construction management system is, based on the establishment of a scientific management system, to build an engineering management information system encompassing all engineering management departments of the head office and design, supervision, and construction units. This system includes computer networks and corresponding databases and software systems, forming an efficient, unified, standardized, and coordinated management and control system for water conservancy and hydropower projects, covering planning and progress, cost, quality, owner funds, engineering technology and documents, material and equipment procurement, construction, and contract management. It also forms an information system from the implementation level and management level of the Three Gorges Project to the decision-making level, as well as various levels of external communication, thereby improving the overall management level of the Three Gorges Project and providing the decision-making level with accurate and timely information necessary for analysis and decision-making. Through efficient and unified information management, and in conjunction with the current situation, it unifies various information from design, supervision, and construction units, thereby achieving the strategic goal of comprehensive information control and management throughout the entire Three Gorges Project management process.

Figure 3 is a flowchart of a method for integrated management of large-scale projects according to an embodiment of this application. As shown in Figure 3, the process includes the following steps:

[0163] Step S301: Obtain target project information. The preliminary estimate subsystem performs multi-level classification and encoding processing on the target project information to obtain the preliminary estimate code.

[0164] In step S302, the contract management subsystem decomposes the target project information, generates multiple project contracts, and associates the multiple project contracts with the budget code.

[0165] In step S303, the construction control subsystem breaks down the project contract into unit projects, encodes the unit projects to obtain unit codes, and associates the quantity data corresponding to the unit projects with the preset construction drawing list.

[0166] In step S304, the joint control subsystem generates a measurement certificate based on the relationship between the engineering contract and the budget code, as well as the relationship between the engineering quantity data and the preset construction drawing list. Based on the measurement certificate, the system performs joint control over the engineering cost, engineering progress, and engineering quality to achieve integrated management of large-scale projects.
