Description

Technical Field

[0001] This disclosure relates to the field of engineering supervision technology, and in particular to a method, apparatus, equipment and storage medium for supervising the subcontracting and transfer of engineering projects. Background Technology

[0002] In actual engineering projects, illegal subcontracting and transfer of contracts can reduce project quality and waste resources. These illegal subcontracting and transfer of contracts are usually secretive and difficult to detect.

[0003] Currently, illegal subcontracting and transfer of engineering projects are usually supervised manually by verifying project qualification information documents and contract texts. This method is highly subjective and can only achieve static supervision, lacking dynamic supervision. The supervision system is not perfect, and the efficiency and accuracy of supervision are relatively low. Summary of the Invention

[0004] To address the aforementioned technical issues, this disclosure provides a method, apparatus, equipment, and storage medium for supervising the subcontracting and transfer of engineering projects.

[0005] The first aspect of this disclosure provides a method for supervising the subcontracting and transfer of engineering projects, including:

[0006] Acquire the pre-set construction data and actual construction data of the project under the pre-set supervision dimensions. The pre-set supervision dimensions include one or more of the following dimensions: management personnel identity information, project manager qualification, fund payment, supplier, contracting qualification, scope of responsibility of engineering subcontracting, material procurement, and scope of professional subcontracting. The pre-set construction data is the construction data of the project under the responsibility of the pre-determined contracting unit, and the actual construction data is the construction data of the actual contracting unit during the actual construction process of the project.

[0007] For each of the preset regulatory dimensions, analyze the deviation between the actual engineering construction data under the dimension and the preset engineering construction data under the dimension;

[0008] Based on the deviations corresponding to each dimension in the preset regulatory dimensions, the analysis examines whether there are target illegal construction risks in the actual construction of the project. The target illegal construction risks include illegal subcontracting risks or transfer of contracts risks.

[0009] A second aspect of this disclosure provides a monitoring device for subcontracting and transfer of engineering projects, comprising:

[0010] The first acquisition module is used to acquire the pre-set engineering construction data and actual engineering construction data of the project under the pre-set supervision dimensions. The pre-set supervision dimensions include one or more of the following dimensions: management personnel identity information, project manager qualification, fund payment, supplier, contracting qualification, engineering subcontracting responsibility scope, material procurement, and professional subcontracting scope. The pre-set engineering construction data is the engineering construction data of the pre-determined contracting unit responsible for the project, and the actual engineering construction data is the engineering construction data carried out by the actual contracting unit during the actual construction process of the project.

[0011] The first analysis module is used to analyze the deviation between the actual engineering construction data and the preset engineering construction data for each of the preset regulatory dimensions.

[0012] The second analysis module is used to analyze whether there are target illegal construction risks in the actual construction of the project based on the deviations corresponding to each dimension in the preset regulatory dimensions. Target illegal construction risks include illegal subcontracting risks or transfer of contracts risks.

[0013] A third aspect of this disclosure provides a computer device including a memory and a processor, wherein the memory stores a computer program that, when executed by the processor, can implement the engineering project subcontracting and sub-contracting supervision method of the first aspect described above.

[0014] The fourth aspect of this disclosure provides a computer-readable storage medium storing a computer program that, when executed by a processor, can implement the project subcontracting and sub-contracting supervision method of the first aspect described above.

[0015] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0016] This disclosure obtains pre-set construction data and actual construction data for an engineering project under pre-defined regulatory dimensions. These pre-defined regulatory dimensions include one or more of the following: management personnel identity information, project manager qualifications, fund payment, supplier, contractor qualifications, scope of responsibility for subcontracting, material procurement, and scope of professional subcontracting. The pre-set construction data refers to the construction data of the pre-determined contractor responsible for the project, while the actual construction data refers to the construction data carried out by the actual contractor during the project's actual construction process. For each pre-defined regulatory dimension, the disclosure analyzes the deviation between the actual construction data and the pre-defined construction data. Based on the deviations corresponding to each dimension, the disclosure analyzes whether there are target illegal construction risks during the actual construction of the project. These target illegal construction risks include illegal subcontracting risks or sub-contracting risks. This disclosure, by acquiring pre-set and actual construction data for engineering projects under various regulatory dimensions, and based on the discrepancies between the actual and pre-set construction data under each regulatory dimension, determines whether there are risks of illegal subcontracting or transfer of contracts during the actual construction of the project. Using multi-source data fusion analysis and fully automated judgment as the core, this approach significantly reduces reliance on manual labor in the supervision of engineering subcontracting and transfer, improves the automation level of engineering project subcontracting and transfer supervision, effectively reduces the investment of resources in supervising engineering subcontracting and transfer by national regulatory departments, local governments, supervision units, and construction units, and enhances the efficiency and accuracy of engineering subcontracting and transfer supervision.

[0028] To better understand the inventive concept of the embodiments of this disclosure, the technical solutions of the embodiments of this disclosure will be described below in conjunction with exemplary embodiments.

[0029] Figure 1 This is a flowchart illustrating a method for supervising the subcontracting and transfer of engineering projects, as provided in this disclosure. This method can be executed by a computer device, which can be understood as any device with computing capabilities and processing power. Figure 1 As shown, the method for supervising the subcontracting and transfer of engineering projects provided in this embodiment includes the following steps:

[0030] Step 110: Obtain the pre-set construction data and actual construction data of the project under the pre-set supervision dimensions. The pre-set supervision dimensions include one or more of the following dimensions: management personnel identity information, project manager qualification, fund payment, supplier, enterprise qualification information, scope of responsibility of engineering subcontractors, material procurement, and scope of professional subcontractors. The pre-set construction data is the construction data of the pre-determined contractors responsible for the project, and the actual construction data is the construction data of the actual contractors during the actual construction process of the project.

[0031] In this embodiment of the disclosure, "preset" can be understood as standard, legal, compliant, etc.

[0032] The pre-set construction data of an engineering project can be understood as the construction data of the pre-determined contractor responsible for the project.

[0033] The pre-selected contractor can be understood as the legal contractor for the project that is determined in advance through bidding.

[0034] The pre-designated contracting units may include the pre-designated general contracting units and the pre-designated subcontracting units for the project. The pre-designated subcontracting units may include pre-designated professional subcontracting units and pre-designated labor subcontracting units.

[0035] The actual construction data of an engineering project can be understood as the construction data carried out by the actual contractors during the actual construction process of the project. Actual contractors can include the actual general contractor and the actual subcontractors of the project; actual subcontractors can include actual professional subcontractors and actual labor subcontractors.

[0036] Computer equipment can obtain the preset construction data of the project under the preset supervision dimension from the preset project file, and obtain the actual construction data of the project under the preset supervision dimension during the actual construction process of the project.

[0037] Pre-defined engineering documents for an engineering project can be understood as the pre-determined basis for the project's construction. These documents may include pre-defined contracts, personnel contracts, procurement contracts, and building information models.

[0038] Building Information Modeling (BIM) is a new tool in architecture, engineering, and civil engineering. It is used to describe computer-aided designs that are primarily three-dimensional, object-oriented, and related to architecture.

[0039] Preset regulatory dimensions may include one or more of the following: management personnel identity information, project leader qualifications, fund payment, supplier, contracting qualifications, scope of responsibility for engineering subcontracting, material procurement, and scope of professional subcontracting.

[0040] Step 120: For each of the preset regulatory dimensions, analyze the deviation between the actual engineering construction data under that dimension and the preset engineering construction data under that dimension.

[0041] In this embodiment of the disclosure, for each of the preset regulatory dimensions, the computer device can analyze the deviation between the actual engineering construction data under that dimension and the preset engineering construction data under that dimension.

[0042] Step 130: Based on the deviations corresponding to each dimension in the preset regulatory dimensions, analyze whether there are target illegal construction risks in the actual construction of the project. Target illegal construction risks include illegal subcontracting risks or transfer of contracts risks.

[0043] In this embodiment of the disclosure, after obtaining the deviations corresponding to each dimension in the preset regulatory dimensions, the computer device can determine whether there is a target illegal construction risk in the actual construction of the project based on the deviations corresponding to each dimension in the preset regulatory dimensions. The target illegal construction risk may include illegal subcontracting risk or transfer of contract risk.

[0044] Therefore, by acquiring pre-set and actual construction data for engineering projects under various regulatory dimensions, and based on the discrepancies between the actual and pre-set construction data under each regulatory dimension, it is possible to determine whether there are risks of illegal subcontracting or transfer of contracts during the actual construction of the project. Supervision of engineering subcontracting and transfer can be significantly reduced by using multi-source data fusion analysis and fully automated judgment as the core. This improves the automation level of engineering subcontracting and transfer supervision, effectively reduces the investment of resources in supervision by national regulatory departments, local governments, supervision units, and construction units, and enhances the efficiency and accuracy of engineering subcontracting and transfer supervision.

[0045] In some embodiments, when the preset regulatory dimension is the management personnel identity information dimension, the preset engineering construction data may include the identity information of the preset management personnel of the preset contractor of the engineering project, and the actual engineering construction data may include the identity information of the actual management personnel at the actual construction site of the engineering project. Specifically:

[0046] Obtaining pre-defined construction data and actual construction data for an engineering project under pre-defined regulatory dimensions can include:

[0047] Obtain the identity information of the pre-designated management personnel of the pre-designated contractor for the project. The identity information includes at least one of iris information, finger vein information, and voiceprint information.

[0048] Collect the identity information of the actual management personnel at the actual construction site of the project.

[0049] In this context, "pre-selected management personnel" can be understood as the legally authorized management personnel pre-determined by the project's pre-contracting unit. Pre-selected management personnel may include one or more of the following: project manager, technical lead, safety manager, and quality manager.

[0050] For example, computer equipment can obtain the identity information of the pre-designated managers of the pre-designated contractors in an engineering project from the pre-designated contract.

[0051] For example, multimodal acquisition terminals can be deployed at actual construction sites. These terminals can include devices such as iris cameras, finger vein sensors, and voiceprint microphones. Computer equipment can acquire iris information of personnel at the construction site through iris cameras, finger vein information through finger vein sensors, and voiceprint information through voiceprint microphones.

[0052] For each of the preset regulatory dimensions, analyze the deviation between the actual engineering construction data under that dimension and the preset engineering construction data under that dimension, including:

[0053] The identity information of the actual managers is compared with the identity information of the preset managers to analyze whether there is any abnormal identity information in the identity information of the actual managers. Abnormal identity information is identity information that is different from the identity information of the preset managers.

[0054] Based on the deviations corresponding to each dimension in the preset regulatory dimensions, determine whether there is a risk of illegal construction during the actual construction of the project, including:

[0055] When there is abnormal identity information among the actual management personnel, it indicates a risk of subcontracting during the actual construction of the project. For example, if there is abnormal identity information among the actual management personnel, it can be determined that subcontracting may have occurred during the actual construction of the project.

[0056] When abnormal identity information is found in the identity information of the actual management personnel, it indicates that there are management personnel from other contracting units among the actual management personnel at the construction site of the project. This suggests that there is a risk of subcontracting in the actual construction of the project.

[0057] In some embodiments, when the preset regulatory dimension is the project manager qualification dimension, the preset engineering construction data may include the qualification information of the preset project manager of the preset contractor of the engineering project, and the actual engineering construction data may include the qualification information of the actual project manager at the actual construction site of the engineering project. Specifically:

[0058] Obtain the pre-set construction data and actual construction data of the project under the pre-set regulatory dimensions, including:

[0059] Obtain the qualification information of the project manager of the pre-contractor for the engineering project;

[0060] Collect the qualification information of the actual project manager at the actual construction site of the project.

[0061] The qualification information of the project leader includes the project leader's qualification registration unit and qualification certificate number.

[0062] For example, the qualification information of the project manager of the project's pre-contractor can be obtained from the project's pre-contracting contract; the qualification information of the actual project manager can be collected from the project's actual contractor's on-site application materials.

[0063] In this context, the project manager of an engineering project can be understood as the main person in charge of the construction of the engineering project. The project manager may include the project manager, the project's safety manager, etc.

[0064] The pre-selected project manager can be understood as the legally designated project manager pre-determined by the pre-selected contractor for an engineering project.

[0065] For each of the preset regulatory dimensions, analyze the deviation between the actual engineering construction data under that dimension and the preset engineering construction data under that dimension, including:

[0066] The qualification information of the actual project manager is compared with the qualification information of the preset project manager to analyze whether the qualification information of the actual project manager matches the qualification information of the preset project manager.

[0067] Based on the deviations corresponding to each dimension in the preset regulatory dimensions, the analysis examines whether there are risks of illegal construction during the actual construction of the project, including:

[0068] When the qualification information of the actual project manager of an engineering project does not match the qualification information of the project's intended project manager, it can be determined that there is a risk of illegal subcontracting or transfer of contract during the actual construction of the project. For example, if the qualification information of the actual project manager of an engineering project does not match the qualification information of the project's intended project manager, it can be determined that there is illegal subcontracting or transfer of contract during the actual construction of the project.

[0069] In some embodiments, when the preset regulatory dimension is the fund payment dimension, the preset construction data may include the preset fund payment account of the preset contractor for the construction project, and the actual construction data may include the actual fund payment account of the preset contractor during the actual construction period of the construction project. Specifically:

[0070] Fund payment accounts may include wage payment accounts and project payment accounts for engineering projects; preset fund payment accounts may include preset wage payment accounts and preset project payment accounts for engineering projects; actual fund payment accounts may include actual wage payment accounts and actual project payment accounts for engineering projects.

[0071] Obtain the pre-set construction data and actual construction data of the project under the pre-set regulatory dimensions, including:

[0072] Obtain the pre-set payment account of the pre-designated contractor for the project;

[0073] Obtain the actual payment account of the contractor during the actual construction period of the project.

[0074] Among them, the computer equipment can obtain the pre-set wage payment account of the pre-set contractor from the pre-set labor contract of the pre-set contractor, and obtain the pre-set project payment account from the pre-set contractor's contract; it can obtain the actual wage payment details and actual project payment details of the pre-set contractor during the actual construction period from the pre-set contractor's bank account statements, and obtain the actual wage payment account from the actual wage payment details; and obtain the actual project payment account from the actual project payment details.

[0075] For each of the preset regulatory dimensions, analyze the deviation between the actual engineering construction data under that dimension and the preset engineering construction data under that dimension, including:

[0076] The actual payment account is compared with the preset payment account to analyze the abnormal accounts and the number of abnormal accounts in the actual payment account. Abnormal accounts are those that are different from the preset payment accounts.

[0077] Calculate the percentage of abnormal accounts among the total number of accounts used for fund payments.

[0078] Analyze whether the actual project payment account in the actual fund payment account corresponds to the preset project payment account in the preset fund payment account;

[0079] Based on the deviations corresponding to each dimension in the preset regulatory dimensions, the analysis examines whether there are risks of illegal construction during the actual construction of the project, including:

[0080] When the proportion of abnormal accounts to the number of actual payment accounts exceeds a first preset threshold, it is determined that there is a risk of illegal subcontracting in the actual construction of the project. For example, when the proportion of abnormal accounts to the number of actual payment accounts exceeds a first preset threshold, it can be determined that there may be illegal subcontracting in the actual construction of the project.

[0081] When the actual project payment account does not match the pre-set project payment account, it indicates a risk of illegal subcontracting during the actual construction of the project. For example, if the actual project payment account does not match the pre-set project payment account, it can be determined that illegal subcontracting may have occurred during the actual construction of the project.

[0082] The first preset percentage threshold can be set as needed, for example, 20%, without any specific limitation here.

[0083] In some embodiments, when the preset regulatory dimension is the supplier dimension, the preset engineering construction data may include preset supplier codes for the main construction materials of the engineering project, and the actual engineering construction data may include the actual supplier codes for the main construction materials at the actual construction site of the engineering project. Specifically:

[0084] Obtain the pre-set construction data and actual construction data of the project under the pre-set regulatory dimensions, including:

[0085] Obtain the pre-set procurement contracts for engineering projects;

[0086] Extract the preset supplier codes for major construction materials from the preset procurement contracts;

[0087] At the actual construction site of the project, the radio frequency identification tags of the main construction materials are scanned to obtain the actual supplier codes of the main construction materials.

[0088] The computer equipment can retrieve the pre-set procurement contract for the project from the project's pre-set engineering documents, and extract the pre-set supplier codes for the main construction materials from the pre-set procurement contract. The pre-set supplier codes can be understood as the supplier codes of the legal suppliers of the main construction materials for the project, determined in advance.

[0089] Computer equipment can scan the radio frequency identification (RFID) tags of the main construction materials at the actual construction site of an engineering project to obtain the actual supplier codes of the main construction materials.

[0090] For each of the preset regulatory dimensions, analyze the deviation between the actual engineering construction data under that dimension and the preset engineering construction data under that dimension, including:

[0091] The actual supplier codes are compared with the preset supplier codes to analyze the abnormal supplier codes and their number. Abnormal supplier codes are those that are different from the preset supplier codes.

[0092] The number of abnormal vendor codes represents the second largest proportion of the actual number of vendor codes.

[0093] Based on the deviations corresponding to each dimension in the preset regulatory dimensions, the analysis examines whether there are risks of illegal construction during the actual construction of the project, including:

[0094] When the second percentage of abnormal supplier codes in the total number of actual supplier codes exceeds a second preset threshold, it is determined that there is a risk of illegal subcontracting in the actual construction of the project. For example, when the second percentage of abnormal supplier codes in the total number of actual supplier codes exceeds a second preset threshold, it can be determined that illegal subcontracting may exist in the actual construction of the project.

[0095] The second preset percentage threshold can be set as needed, and no specific limitation is made here.

[0096] In some embodiments, when the preset regulatory dimension is the contracting qualification dimension, the preset engineering construction data may include the preset subcontracting qualification requirements for the subcontractors of the engineering project, and the actual engineering construction data may include the actual subcontracting qualification information of the actual subcontractors at the actual construction site of the engineering project. Specifically:

[0097] Pre-set subcontracting qualification requirements may include pre-set professional subcontracting qualification requirements for professional subcontracting units and pre-set labor subcontracting qualification requirements for labor subcontracting units.

[0098] The actual subcontracting qualification information may include the actual professional subcontracting qualification information of the actual professional subcontracting unit and the actual labor subcontracting qualification information of the actual labor subcontracting unit.

[0099] The pre-defined subcontractor qualification requirements can be set as needed; there are no restrictions here.

[0100] Qualification information can be understood as engineering construction qualification information, special operation qualification information, personnel skill qualification information, etc.

[0101] Obtain the pre-set construction data and actual construction data of the project under the pre-set regulatory dimensions, including:

[0102] Obtain the pre-set subcontracting qualification requirements for the engineering project;

[0103] Obtain the actual subcontracting qualification information of the actual subcontractors at the actual construction site of the project.

[0104] Among them, computer equipment can obtain pre-set professional subcontracting contracts and pre-set labor subcontracting contracts from the pre-set engineering documents of the engineering project, obtain the pre-set professional subcontracting qualification requirements of the professional subcontracting unit from the pre-set professional subcontracting contract, and obtain the pre-set labor subcontracting qualification requirements of the labor subcontracting unit from the pre-set labor subcontracting contract.

[0105] For example, a natural language processing (NLP) model can be used to deconstruct a pre-defined subcontracting contract, and an artificial intelligence model can be used to determine the minimum subcontracting qualification requirements in the relevant provisions of the deconstructed pre-defined subcontracting contract, and these minimum qualification requirements can be used as the pre-defined subcontracting qualification requirements.

[0106] By combining the "Four Databases and One Platform" website database, the actual subcontracting qualification information of the actual subcontractors in the actual construction site of the project can be obtained from the application materials submitted by the actual subcontractors.

[0107] For each of the preset regulatory dimensions, analyze the deviation between the actual engineering construction data under that dimension and the preset engineering construction data under that dimension, including:

[0108] Analyze whether the actual subcontractor qualification information meets the preset subcontractor qualification requirements.

[0109] Based on the deviations corresponding to each dimension in the preset regulatory dimensions, the analysis examines whether there are risks of illegal construction during the actual construction of the project, including:

[0110] When the actual subcontractor's qualification information does not meet the preset subcontractor qualification requirements, it can be determined that there is a risk of illegal subcontracting in the actual construction of the project. For example, when the actual subcontractor's qualification information does not meet the preset subcontractor qualification requirements, it can be determined that there is illegal subcontracting in the actual construction of the project.

[0111] In some embodiments, when the preset regulatory dimension is the scope of engineering responsibility dimension, the preset engineering construction data may include the preset allowed subcontracting responsibility scope of the engineering project, and the actual engineering construction data may include the actual subcontracting responsibility scope during the actual construction process of the engineering project. Specifically:

[0112] Obtain the pre-set construction data and actual construction data of the project under the pre-set regulatory dimensions, including:

[0113] Obtain the pre-defined permitted subcontracting responsibilities for the engineering project;

[0114] Obtain point cloud data of the construction surface during the actual construction process of the engineering project;

[0115] The area corresponding to the point cloud data of the construction surface is determined as the actual subcontractor's responsibility area.

[0116] The preset allowed subcontracting responsibility scope can be understood as a pre-defined project area or project section that is permitted to be subcontracted. This preset allowed subcontracting responsibility scope could include waterproofing works, curtain wall installation, etc.

[0117] Computer equipment can obtain the preset building information model of an engineering project from the preset engineering files of the engineering project, and obtain the preset allowed subcontracting responsibility scope of the engineering project from the preset building information model;

[0118] Computer equipment can use laser equipment to scan and obtain point cloud data of the construction surface during the actual construction process of an engineering project, and determine the area corresponding to the point cloud data of the construction surface as the actual subcontracting responsibility area.

[0119] For each of the preset regulatory dimensions, analyze the deviation between the actual engineering construction data under that dimension and the preset engineering construction data under that dimension, including:

[0120] By performing spatial overlap analysis between the actual subcontracting responsibility scope and the preset allowed subcontracting responsibility scope, the overlap volume between the actual subcontracting responsibility scope and the preset allowed subcontracting responsibility scope is obtained;

[0121] Calculate the third proportion of the overlapping volume in the subcontracted volume;

[0122] Based on the deviations corresponding to each dimension in the preset regulatory dimensions, the analysis examines whether there are risks of illegal construction during the actual construction of the project, including:

[0123] When the third percentage of the overlapping volume in the subcontracted volume is less than a third preset percentage threshold, it is determined that there is a risk of illegal subcontracting in the actual construction of the project. For example, when the third percentage of the overlapping volume in the subcontracted volume is less than a third preset percentage threshold, it can be determined that there is illegal subcontracting in the actual construction of the project.

[0124] The third preset percentage threshold can be set as needed, for example, 10%, without specific limitations.

[0125] In some embodiments, when the preset regulatory dimension is the professional subcontracting scope dimension, the preset engineering construction data may include the preset planned professional subcontracting scope of the engineering project, and the actual engineering construction data may include the actual professional subcontracting scope during the actual construction process of the engineering project.

[0126] Obtain the pre-set construction data and actual construction data of the project under the pre-set regulatory dimensions, including:

[0127] Obtain the pre-planned scope of professional subcontracting for the engineering project;

[0128] To obtain the scope of the actual professional subcontracting work during the actual construction process of the project.

[0129] Among them, it is possible to obtain the scope of pre-planned professional subcontracting projects in the tender documents, sub-bid plans and other professional subcontracting approval documents of engineering projects;

[0130] Obtain the scope of the actual professional subcontracted work from the application materials submitted by the actual subcontractors for entry into the project.

[0131] For each of the preset regulatory dimensions, analyze the deviation between the actual engineering construction data and the preset engineering construction data, including:

[0132] Analyze whether the actual scope of the professional subcontracting project falls within the pre-planned scope of the professional subcontracting project;

[0133] Based on the deviations corresponding to each dimension in the preset regulatory dimensions, the analysis examines whether there are risks of illegal construction during the actual construction of the project, including:

[0134] When the actual scope of subcontracted work differs from the pre-planned scope, it indicates a risk of illegal subcontracting during the actual construction of the project. For example, if the actual scope of subcontracted work differs from the pre-planned scope, it can be determined that illegal subcontracting has occurred during the actual construction of the project.

[0135] In some embodiments, before obtaining the preset construction data and actual construction data of an engineering project under a preset regulatory dimension, the computer device may obtain the preset engineering file of the engineering project; extract the subcontracting clause field from the preset engineering file; perform hierarchical hash calculation on the subcontracting clause field to generate a unique fingerprint of the subcontracting clause field; write the unique fingerprint into the subcontracting clause field to obtain the preset construction data of the engineering project; and upload the preset construction data to the blockchain for storage.

[0136] One approach is to use a hierarchical hash algorithm to construct a Merkle tree, which can then be used to generate a unique fingerprint for the subcontracting terms field.

[0137] Preset engineering construction data can be written into the consortium blockchain based on the Practical Byzantine Fault Tolerance (PBFT) mechanism, so as to upload the preset engineering construction data to the blockchain for storage.

[0138] PBFT is a consensus algorithm for distributed systems designed to solve the problem of achieving consistent decisions in scenarios with malicious nodes (Byzantine nodes).

[0139] Consortium blockchains are only for members of a specific group and a limited number of third parties. They designate multiple pre-selected nodes as ledger keepers, and the generation of each block is jointly determined by all the pre-selected nodes.

[0140] Therefore, pre-set engineering construction data can be encrypted and stored in the blockchain, which can prevent the pre-set engineering construction data from being tampered with and improve data security.

[0141] In some embodiments, when it is determined that there is a risk of illegal subcontracting in the actual construction of an engineering project, computer equipment can freeze the project funds of the pre-subcontractors among the pre-contractors of the engineering project.

[0142] When it is determined that there is a risk of subcontracting during the actual construction of an engineering project, computer equipment can freeze the project funds of the pre-designated general contractor among the pre-designated contractors for the project. This can mitigate or prevent illegal subcontracting and transfer of contracts.

[0143] In some embodiments, when it is determined that there is a risk of illegal construction in the actual construction of an engineering project, the computer equipment can identify the illegal construction area corresponding to the risk of illegal construction and shut down the access control system of the illegal construction area to reduce the number of people in the illegal construction area and slow down or prevent illegal subcontracting and transfer of contracts.

[0144] In some embodiments, when it is determined that there is a risk of illegal construction in the actual construction of an engineering project, the computer device can obtain the spatiotemporal stamp data corresponding to the time of determination of the risk of illegal construction; and encapsulate the spatiotemporal stamp data corresponding to the time of determination of the risk of illegal construction, the actual engineering construction data corresponding to the risk of illegal construction, and the deviation between the actual engineering construction data and the preset engineering construction data according to the preset blockchain evidence storage format to obtain the evidence package of the risk of illegal construction.

[0145] Evidence of the risk of illegal construction by the target will be uploaded to the blockchain for storage.

[0146] The preset blockchain evidence storage format can be understood as a blockchain evidence storage format that complies with the requirements of the Electronic Signature Law.

[0147] Therefore, when it is determined that there is a risk of illegal subcontracting or transfer of contract in the actual construction of an engineering project, an evidence package of illegal subcontracting or transfer of contract risk can be generated, thereby solidifying the evidence of illegal subcontracting or transfer of contract, providing litigation evidence for litigation of illegal subcontracting or transfer of contract, and improving the efficiency of litigation of illegal subcontracting or transfer of contract.
