Description

Technical Field

[0001] The present invention relates to the technical field of project management, and more specifically, to a full-process tracking and supervision system for an engineering project. Background Art

[0002] The whole process tracking and supervision of engineering projects is an activity to audit and supervise the legality, authenticity and standardization of the whole process of construction project implementation, including pre-construction audit, construction audit and post-completion audit. Pre-construction audit, construction audit and post-completion audit run through the whole process of the project. From the perspective of audit consistency and completeness, the three parts complement each other and are indispensable.

[0003] In the existing technology, the whole process tracking audit of the project can be dynamically audited by time period and content, making the audit ideas clearer and relieving the pressure of processing a large amount of data in a short time. On the other hand, the tracking audit can analyze the related factors that affect each other in the previous and subsequent stages, and can dynamically supervise the operation of each stage of the whole life cycle. In the construction stage, after the tracking audit personnel sign and approve the measured records with the construction party, the supervision party, and the construction party at the construction site, the corresponding engineering data can be calculated immediately, avoiding the evasion and the long-term non-signing and large backlog of the previous drawbacks, compressing the long traditional audit cycle in advance and digesting it in the middle stage, so that the over-concentrated amount in the past can be dispersed as evenly as possible in the construction stage, thereby speeding up the settlement audit, increasing the audit intensity, and improving the economic benefits. The tracking audit is an audit and supervision of the technical and economic activities of the construction project from the preparation to the completion acceptance. It not only emphasizes the cost control in the construction stage, but also pays attention to the tracking audit of the early decision-making work, carries out in-depth tracking audit of design quality, and actively intervenes in the tracking audit of the bidding stage, so that the audit work develops in a diversified way. Prior art 1 (CN105279614A) "Process-based business audit system and method" parses and encapsulates business system data of different protocol types into standardized data in a unified format; according to the defined rule nodes, rule clusters, processes and indicators, the rule node matching, rule cluster matching, process matching and indicator analysis of the actual business system data after standardization are completed to determine whether the content to be audited meets the standards and to make timely warnings. In prior art 1, the process-based business audit system and method abstracts the entire business audit process, so that the audit analysis of business security can be realized through a unified and scalable method, greatly reducing the cost of business security audits. Prior art 2 (CN111461644A) "An audit information management and control platform" includes an audit portal module, which is used as the audit information operation access entrance of the audit information management and control platform; an audit management domain, which is used to manage the processes of various preset audit projects; and an audit operation domain, which includes multiple types of audit operation models, wherein the various types of audit operation models are associated with the audit management domain with the core management objects in the preset audit projects as nodes. Existing technology 3 can realize the intelligent control framework of audit project process, optimize and improve the online level of audit business, focus on finding more difficult audit problems more accurately and quickly, and improve audit efficiency and effectiveness. Represented by existing technologies 1 and 2, the systematic and unified tracking and supervision management of the entire project process is realized, which fundamentally improves the service quality of audit business.

[0004] Based on the existing technologies 1 and 2, engineering construction projects generally go through investment decision-making, design, bidding, construction, completion settlement and other stages. If the tracking audit is involved in real-time tracking at different stages, the audit effect will be different. In the existing technology, there is no clear regulation on the time intervention point of the tracking audit. In theory, the earlier the audit is involved, the better. However, on the one hand, due to the lack of professional ability of auditors in evaluating whether the early decision is scientific, they cannot undertake this audit task. On the other hand, because the investors believe that the tracking audit is only to prevent the construction unit from overestimating and miscalculating during the construction stage, in the practice of tracking audit, most of them are involved in the tracking audit during the construction and completion settlement stages. Then the cost affected by the early decision-making, design and bidding stages cannot be controlled, and the effect of the tracking audit is not sufficient and obvious. For this reason, the existing technology 3 (CN111652458A) "A method for engineering audit based on blockchain technology" audits the project through the data layer to determine whether it is reasonable and effective; verifies the project through the data verification mechanism in the network layer; and calculates the time point of the project through the consensus layer to determine whether it meets the expected standard. Through blockchain technology, engineering documents can be audited. Since the blockchain system consists of a data layer, a network layer, a consensus layer, an incentive layer, a contract layer, and an application layer, the project can be audited. After that, professionals can check the process, management standards, and rules and regulations of the workpiece, so that the project can be audited comprehensively, the work efficiency can be improved, and the audit of the project is convenient. In addition, there is a lack of effective definition and unified management of the project maintenance time limit, so it is impossible to give timely warnings and intervention measures for the tracking and supervision of the entire process of the project. Therefore, the existing technology 4 (CN107833012A) "A management system for the time-limited completion of audit projects" proposes to use a database module and a system menu module to achieve scientific management of the time limit of project audit work through an auxiliary OA system. However, the existing technologies 3 and 4 are more concerned with the immutability of the time node control of the project tracking audit, requiring all parties in the project to strictly implement the working hours in a unified manner, so as to ensure the scientific management of the time limit of the project audit work; however, the control technology schemes of the various work time nodes involved in the entire process of the project are not elaborated in detail, and the handling measures for the overtime of the project audit work are not involved.

[0005] In addition, in the full-process tracking audit of engineering projects, more emphasis is placed on optimizing the management of the entire audit process from the five dimensions of audit nodes, audit objects, audit quality, audit efficiency, and audit work mode. However, in the existing technology, there is no relevant optimization research involved in the full-process tracking and supervision of engineering projects.

[0006] In summary, it is necessary to study a full-process tracking and supervision system for engineering projects to improve the work quality of full-process tracking and auditing of engineering projects. Summary of the invention
