Description

Technical Field

[0001] This invention relates to the field of automated management and control technology, and in particular to a method and system for automated management and control of the entire construction project process. Background Technology

[0002] Currently, with the continuous promotion and improvement of infrastructure construction, various infrastructure projects are increasing, which also leads to a continuous increase in the difficulty of infrastructure construction. In the construction and operation of large-scale infrastructure projects, many risks and problems need to be effectively managed and resolved. Construction phase risks are important indicators affecting project construction progress, quality, safety, and cost. Construction projects involve a wide range of aspects, including land, design, construction, materials, personnel, and equipment management, which interact to cause overall risk changes. Therefore, high-quality management of the construction process has become an important means to ensure project quality and progress. Construction indicators have become an important basis for evaluating management. Through detailed research on the control of construction indicators, it is helpful to achieve risk control during the construction phase of the project, reduce project economic costs, and improve the project's competitiveness and economic benefits.

[0003] Due to the limitations of the current cost coding rules for large airport construction, cost management and contract management cannot be directly linked through system coding. This leads to information isolation between contracts under the same approved budget, resulting in the following specific problems in the use of large airport construction systems: 1. During the contract entry phase, the budget list needs to be manually broken down, verified, matched according to the system coding rules, manually imported, and then manually reviewed. This requires a significant amount of time from professional personnel and has a high probability of error. 2. During the usage phase, real-time summarization, analysis, and comprehensive query functions for various aspects of project investment completion, cost control, and fund utilization are not available.

[0004] Therefore, the present invention provides a method and system for automated management and control of the entire construction project process. Summary of the Invention

[0005] This invention discloses a method and system for automated management and control of the entire construction project process. It utilizes the existing coding rules for large airport construction to further upgrade the functions, expand the depth and recognition capabilities of the coding, and add automated functional attributes to the coding. Specifically, it adjusts the coding rules for the budget of large airport construction to include data standards such as project division and bill of quantities pricing specifications, and establishes a cost management data standard system that runs through the entire process of project planning, design, bidding, implementation, and acceptance, thereby improving the accuracy of project cost management.

[0006] This invention provides a method for automated management and control of the entire construction project process, comprising:

[0022] Step 23: Extract the identified project cost value and the marked project cost value corresponding to each contract execution project from the cost verification information chain, filter out a class of contract execution projects whose identified project cost value and marked project cost value are inconsistent, and establish a first cost error range for the class of contract execution projects based on the corresponding project cost value difference;

[0023] Step 24: Filter out two types of contract execution projects with the same cost value of the identified project and the cost value of the marked project.

[0028] Step 33: Input the cost allocation results into the overall construction model for verification, obtain the material sufficiency characteristics corresponding to each project execution step, adjust the cost of the materials used based on the material sufficiency characteristics, and generate a cost control plan corresponding to each contract execution project.

[0029] Step 34: During construction, determine the current contract execution item corresponding to the current construction progress, locate the qualified cost corresponding to the current contract execution item in the cost control plan, and use the qualified cost to verify the cost control of the current contract execution item.

[0031] Also includes:

[0032] Based on the cost control verification results, determine the actual cost allocation corresponding to the current contract execution project, and establish the cost qualification characteristics corresponding to each current project execution step.

[0033] When the cost qualification characteristics are abnormal, determine the current actual execution process, generate an early warning message, and play it.

[0034] In one feasible approach

[0035] Step 4 includes:

[0036] Step 41: Construct the actual construction schedule of the large airport construction project based on the execution start time corresponding to each of the contract execution items;

[0037] Step 42: Obtain the control and verification information corresponding to each of the contract execution projects, and determine the cumulative construction cost information of the large airport construction project in combination with the actual construction progress;

[0048] The cost analysis module is used to obtain the contract bill of quantities for the large airport construction project, and to classify and analyze the contract bill of quantities using the cost management baseline to obtain the cost information corresponding to each contract execution item of the large airport construction project.

[0049] The cost verification module is used to construct a cost control plan for the corresponding contract execution project using the cost information, and to perform cost control verification for each of the contract execution projects.

[0050] The control and early warning module is used to construct the real-time cost of the large airport construction project based on the control and verification information corresponding to each contract execution project, and to locate target contract execution projects with excessive costs and issue early warnings in conjunction with the cost management baseline.

[0051] In one feasible approach

[0052] The preliminary cost estimation module includes:

[0065] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0066] Example 1

[0067] This embodiment provides a method and system for automated management and control of the entire construction project process, such as... Figure 1 As shown, it includes:

[0068] Step 1: Analyze the preliminary design budget and preliminary execution budget of the large airport construction project based on the coding structure of the large airport construction project, and construct the cost management baseline of the large airport construction project;

[0069] Step 2: Obtain the contract bill of quantities for the large airport construction project, and use the cost management baseline to classify and analyze the contract bill of quantities to obtain the cost information corresponding to each contract execution item of the large airport construction project;

[0070] Step 3: Use the cost information to construct a cost control plan for the corresponding contract execution project, and verify the cost control for each contract execution project.

[0071] Step 4: Construct the real-time cost of the large airport construction project based on the control and verification information corresponding to each contract execution project, and locate the target contract execution projects with excessive costs by combining the cost management baseline and issue an early warning.

[0072] In this example, the coding structure represents the national standard list of the "Code for Pricing of Engineering Quantities" (GB50500-2013) and the civil aviation standard list of the "Code for Pricing of Engineering Quantities of Civil Aviation Professional Engineering" (MH5028-2014) added to the existing coding rules for the construction of large airports. The coding structure includes system coding fields to achieve consistency and continuity of preliminary estimate, budget, and settlement data information.

[0073] In this example, the preliminary design budget represents the project design carried out before the construction of the large airport, including the appearance of the large airport, the investment of funds, and the investment of manpower;

[0074] In this example, the preliminary project execution budget represents the construction allocation prior to the construction of the large airport, including the allocation and appointment of manpower;

[0075] In this example, the contract bill of quantities details the quantities and corresponding prices of all items in the entire project, which is used for contract signing and project progress management.

[0076] In this example, the cost management baseline represents a benchmark used to compare and monitor the actual cost performance of a project;

[0077] In this example, the contract execution project refers to the project to be executed based on the requirements for the construction of a large airport, generated according to the contract engineering list;

[0078] In this example, the real-time cost increases continuously as construction progresses.

[0079] The working principle and beneficial effects of the above technical solution are as follows: In order to establish a cost management data standard system that runs through the entire process of project planning, design, bidding, implementation, and acceptance, and to significantly improve the efficiency of project cost management, the preliminary design budget and preliminary execution budget of this construction project are first constructed based on the coding structure of large airport construction projects, thereby establishing a cost management baseline. Then, the contract bill of quantities is classified and analyzed to determine the cost information corresponding to each contract execution item. Then, a cost control plan is established for each contract execution item, and its execution process is controlled and verified, as well as the real-time cost of the construction process is calculated. When necessary, corresponding early warning work is carried out. In this way, according to national standards, the depth and recognition capability of coding can be expanded, and the automated functional attributes of coding can be increased, thereby enabling time-limited automated cost control and improving the transparency of construction projects.

[0080] Example 2

[0081] Based on Example 1, the method for automated management and control of the entire construction project process, step 1 includes:

[0082] Step 11: Obtain the coding structure of the large airport construction project, determine the coding meaning of each structural bit according to the coding structure, and establish the semantic decoding rules of the large airport construction project according to the preset national standard list and civil aviation standard list;

[0083] Step 12: Obtain several engineering codes for the large airport construction project, perform semantic analysis on each engineering code using the semantic decoding rules to obtain several semantic engineering information of the large airport construction project, and construct the construction concept structure of the large airport construction project using the semantic engineering information.

[0084] Step 13: The construction concept structure is layered to obtain several independent substructures. Based on the connection relationship between different independent substructures, several structural logical relationships of the large airport construction project are established. Combined with the structural foundation corresponding to each independent substructure, the preliminary design budget of the large airport construction project is established.

[0085] Step 14: Analyze the construction material information corresponding to each independent substructure, determine the construction execution process corresponding to each independent substructure based on the construction method corresponding to each construction material, and generate the preliminary execution budget of the large airport construction project.

[0086] Step 15: Using the preliminary design budget and the preliminary execution budget of the project, determine several construction steps of the large airport construction project, determine the cost information corresponding to each construction step, and establish the cost management baseline of the large airport construction project.

[0087] In this example, semantic decoding rules represent expressing the encoded meaning semantically, for example... Figure 2 The code in the middle is FX0101010101, and the corresponding decoded meaning is: Flight area\Airport runway engineering\Underpass tunnel\Earthwork excavation\Site leveling\Earthwork excavation and filling;

[0088] In this example, the encoding identification information represents the encoding corresponding to a contract execution item;

[0089] In this example, the cost representation information chain represents an information chain generated by statistically analyzing the coded identification information corresponding to different contract execution projects;

[0090] In this example, the preset cost error ratio is 0.12%.

[0091] The working principle and beneficial effects of the above technical solution are as follows: By utilizing the contract bill of quantities and contract bill of quantities coding rules to construct the coded identification information corresponding to each contract execution item, a cost identification information chain is built. Then, cost scanning is performed using the cost baseline to construct a cost verification information chain. By analyzing the cost values ​​of identified items and marked items, contract execution items are classified, and different error ranges are configured for different categories of contract execution items. Finally, the cost information corresponding to each contract execution item is determined. In this way, all contract execution items can be analyzed simultaneously, and the corresponding errors are taken into account during the analysis process, effectively improving the credibility of cost information and providing strong reference evidence for construction.

[0092] Example 4

[0093] Based on Example 1, the method for automated management and control of the entire construction project process, step 3 includes:

[0094] Step 31: Based on the cost information, determine the effective cost range corresponding to each of the contract execution items; construct the overall construction model of the large airport construction project according to the contract bill of quantities; run the overall construction model to determine the project execution steps corresponding to each of the contract execution items; and determine the material quantity and material properties of the materials used for each of the project execution steps respectively.

[0095] Step 32: Determine the material cost corresponding to each material used based on the material properties, determine the cost weight corresponding to each material used in combination with the corresponding material quantity, count the number of materials used for each contract execution project, and allocate the cost of each material used based on the corresponding cost weight and the effective cost range corresponding to the contract execution project.

[0096] Step 33: Input the cost allocation results into the overall construction model for verification, obtain the material sufficiency characteristics corresponding to each project execution step, adjust the cost of the materials used based on the material sufficiency characteristics, and generate a cost control plan corresponding to each contract execution project.

[0097] Step 34: During construction, determine the current contract execution item corresponding to the current construction progress, locate the qualified cost corresponding to the current contract execution item in the cost control plan, and use the qualified cost to verify the cost control of the current contract execution item.

[0098] In this example, the effective cost range represents the reasonable range of costs required to execute the contract.

[0099] In this example, the overall construction model represents the contents of the contract bill of quantities using a model-based approach. This model can represent the completed model of a large airport construction project.

[0100] In this example, a contract execution project can correspond to one or more project execution steps, and the project execution steps represent the operations required to complete a contract execution project;

[0101] In this example, materials are used to represent the materials needed when carrying out the project execution steps, such as concrete and steel bars needed when building the foundation;

[0102] In this example, the quantity of material represents the required amount of a material to be used, such as: 5 tons of concrete are needed when constructing a foundation.

[0103] In this example, material properties represent a physical property of a material;

[0104] In this example, the cost weight represents the input cost of using materials based on the amount of materials. Generally speaking, the larger the amount of materials, the larger the cost weight.

[0105] In this example, the material adequacy characteristic refers to the sufficiency of the materials available for use when performing a step in a project execution;

[0106] In this example, cost adjustment refers to the process of adjusting the input costs for insufficient use of materials.

[0107] The working principle and beneficial effects of the above technical solution are as follows: By constructing an overall construction model of a large airport construction project, the project execution steps corresponding to different contract execution projects are simulated, thereby determining the materials required for each project execution step and their quantities. Then, the cost of each material is determined by utilizing the material properties, thus rationally allocating the effective cost of the contract execution project to the corresponding materials. The allocation results are then verified using the overall construction model, and cost adjustments are made when necessary, thereby constructing a cost control scheme. Finally, during construction, cost control verification is carried out according to the cost control scheme, effectively avoiding the problem of uneven fund allocation.

[0108] Example 5

[0109] Based on Example 4, the method for automated management and control of the entire construction project process further includes:

[0110] Based on the cost control verification results, determine the actual cost allocation corresponding to the current contract execution project, and establish the cost qualification characteristics corresponding to each current project execution step.

[0111] When the cost qualification characteristics are abnormal, determine the current actual execution process, generate an early warning message, and play it.

[0112] Example 6

[0113] Based on Example 1, the method for automated management and control of the entire construction project process, step 4 includes:

[0114] Step 41: Construct the actual construction schedule of the large airport construction project based on the execution start time corresponding to each of the contract execution items;

[0115] Step 42: Obtain the control and verification information corresponding to each of the contract execution projects, and determine the cumulative construction cost information of the large airport construction project in combination with the actual construction progress;

[0116] Step 43: Use the cost management baseline to evaluate the cumulative construction cost information and screen target contract execution projects with excessive costs;

[0117] Step 44: Obtain the excess amount corresponding to the target contract execution project, locate the execution address corresponding to the target contract execution project, and issue a corresponding warning to the execution address.

[0118] The working principle and beneficial effects of the above technical solution are as follows: Based on the control and verification information of the contract execution projects, the cumulative construction cost information of the large airport construction is constructed, and then the cost is evaluated. The contract execution projects with excessive costs are further screened and located, and corresponding early warnings are issued based on the corresponding excess amount. In this way, the actual cost investment can be corrected, and the phenomenon of insufficient funds in the future can be avoided.

[0119] Example 7

[0120] Based on Example 6, the method for automated management and control of the entire construction project process further includes:

[0121] When executing a target contract project that does not exceed cost limits, generate security information.

[0122] The working principle and beneficial effects of the above technical solution are as follows: When all contract execution items are qualified, safety information is generated, and relevant personnel can continue construction.

[0123] Example 8

[0124] Based on Example 1, the method for automated management and control of the entire construction project process further includes:

[0125] The execution workload corresponding to each contract execution project is obtained. Based on the execution workload, corresponding construction personnel are matched for each contract execution project, and the work details of each construction personnel are generated and displayed.

[0126] The working principle and beneficial effects of the above technical solution are as follows: By assigning different construction personnel to different contract execution projects, the construction progress can be guaranteed, and the construction personnel can be reasonably arranged to reduce the input of labor costs.

[0127] Example 9

[0128] This example provides an automated management and control system for the entire construction project process, such as... Figure 3 As shown, it includes:

[0129] The preliminary cost estimate module is used to analyze the preliminary design cost estimate and preliminary execution cost estimate of the large airport construction project based on the coding structure of the large airport construction project, and to construct the cost management baseline of the large airport construction project.

[0130] The cost analysis module is used to obtain the contract bill of quantities for the large airport construction project, and to classify and analyze the contract bill of quantities using the cost management baseline to obtain the cost information corresponding to each contract execution item of the large airport construction project.

[0131] The cost verification module is used to construct a cost control plan for the corresponding contract execution project using the cost information, and to perform cost control verification for each of the contract execution projects.

[0132] The control and early warning module is used to construct the real-time cost of the large airport construction project based on the control and verification information corresponding to each contract execution project, and to locate target contract execution projects with excessive costs and issue early warnings in conjunction with the cost management baseline.

[0133] In this example, the coding structure represents the national standard list of the "Code for Pricing of Engineering Quantities" (GB50500-2013) and the civil aviation standard list of the "Code for Pricing of Engineering Quantities of Civil Aviation Professional Engineering" (MH5028-2014) added to the existing coding rules for the construction of large airports. The coding structure includes system coding fields to achieve consistency and continuity of preliminary estimate, budget, and settlement data information.

[0136] In this example, the contract bill of quantities details the quantities and corresponding prices of all items in the entire project, which is used for contract signing and project progress management.

[0137] In this example, the cost management baseline represents a benchmark used to compare and monitor the actual cost performance of a project;

[0138] In this example, the contract execution project refers to the project to be executed based on the requirements for the construction of a large airport, generated according to the contract engineering list;

[0139] In this example, the real-time cost increases continuously as construction progresses.

[0140] The working principle and beneficial effects of the above technical solution are as follows: In order to establish a cost management data standard system that runs through the entire process of project planning, design, bidding, implementation, and acceptance, and to significantly improve the efficiency of project cost management, the preliminary design budget and preliminary execution budget of this construction project are first constructed based on the coding structure of large airport construction projects, thereby establishing a cost management baseline.

When necessary, corresponding early warning work is carried out. In this way, according to national standards, the depth and recognition capability of coding can be expanded, and the automated functional attributes of coding can be increased, thereby enabling time-limited automated cost control and improving the transparency of construction projects.

[0141] Example 10

[0142] Based on Example 9, the preliminary budget module of the automated management and control system for the entire construction project process includes:

[0143] The first execution unit is used to obtain the coding structure of the large airport construction project, determine the coding meaning of each structural bit according to the coding structure, and establish the semantic decoding rules of the large airport construction project according to the preset national standard list and civil aviation standard list.

[0144] The second execution unit is used to obtain several engineering codes of the large airport construction project, perform semantic analysis on each engineering code using the semantic decoding rules, obtain several semantic engineering information of the large airport construction project, and construct the construction concept structure of the large airport construction project using the semantic engineering information.

[0145] The third execution unit is used to process the construction concept structure into layers to obtain several independent substructures, establish several structural logical relationships of the large airport construction project based on the connection relationship between different independent substructures, and establish the preliminary design budget of the large airport construction project in combination with the structural foundation corresponding to each independent substructure.

[0146] The fourth execution unit is used to analyze the construction material information corresponding to each independent substructure, determine the construction execution process corresponding to each independent substructure according to the construction method corresponding to each construction material, and generate the preliminary execution budget of the large airport construction project.

[0147] The fifth execution unit is used to determine several construction steps of the large airport construction project using the preliminary design budget and the preliminary execution budget of the project, and to determine the cost information corresponding to each construction step, and to establish the cost management baseline of the large airport construction project.

[0148] In this example, semantic decoding rules represent expressing the encoded meaning semantically, for example... Figure 2 The code in the middle is FX0101010101, and the corresponding decoded meaning is: Flight area\Airport runway engineering\Underpass tunnel\Earthwork excavation\Site leveling\Earthwork excavation and filling;

[0149] In this example, the encoding identification information represents the encoding corresponding to a contract execution item;

[0150] In this example, the cost representation information chain represents an information chain generated by statistically analyzing the coded identification information corresponding to different contract execution projects;

[0151] In this example, the preset cost error ratio is 0.12%.

[0152] The working principle and beneficial effects of the above technical solution are as follows: By utilizing the contract bill of quantities and contract bill of quantities coding rules to construct the coded identification information corresponding to each contract execution item, a cost identification information chain is built. Then, cost scanning is performed using the cost baseline to construct a cost verification information chain. By analyzing the cost values ​​of identified items and marked items, contract execution items are classified, and different error ranges are configured for different categories of contract execution items. Finally, the cost information corresponding to each contract execution item is determined. In this way, all contract execution items can be analyzed simultaneously, and the corresponding errors are taken into account during the analysis process, effectively improving the credibility of cost information and providing strong reference evidence for construction.
