[0001] The present invention belongs to the technical field of refined construction management, and relates to a refined management method and device during the engineering construction period based on BIM multi-information integration and drive. Background Art

[0002] In the field of engineering construction, the use of Building Information Modeling (BIM) for project management has gradually become an industry trend. The unified BIM model can not only integrate information from all stages of the project, but also provide multi-dimensional refined control methods for project management. BIM technology can provide optimal resource allocation, real-time monitoring of progress, refined control of quality and safety, and effective cost management methods, including engineering data and model integration, construction process simulation and optimization, dynamic resource allocation and adjustment, real-time progress monitoring and early warning, quality and safety analysis and control, cost management and risk control, information coordination and communication mechanism, feedback and adjustment cycle mechanism, etc.

[0003] At present, BIM-based engineering management has been widely applied, but there is still much room for research in the following areas: (1) There is a lack of research on the driving effect and driving factors of BIM on project management and control, and no unified methodology has been formed; (2) Most studies only discuss control from the perspective of a single information element (such as cost, safety, etc.), and lack research on macro information flows under multi-dimensional information interaction and coupling conditions in actual situations. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a method and device for refined management of engineering construction period based on BIM multi-information integration and drive, fully consider the characteristics of BIM data information flow and business management, conduct research on the driving mechanism of refined management of multi-information based on BIM, and form innovative research with macro-control ideas.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a refined management method for engineering construction period based on BIM multi-information integration and driving, comprising the following steps: S1, the construction period is divided into T construction sub-stages, the current construction sub-stage is recorded as stage t, its previous sub-stage is t-1, and the next sub-stage is t+1; S2, for each sub-stage t, using the building information model as a carrier, the historical information is transmitted, and the real-time multi-information is integrated and updated to obtain the information model BIMt that integrates the construction information of the current sub-stage; S3, for BIMt, uses pre-defined indicator calculation rules and models, big data and artificial intelligence algorithms to conduct indicator evaluation and risk prediction on the information obtained at the current stage, and generate refined management and control plans; S4, in the next stage t+1, repeat the above process of S2~S3 to update and accumulate information.

[0006] In S2, the transmission of historical information includes: S2-1, obtaining the information model library BIMt-1 generated at the end of the previous sub-stage t-1; S2-2, split BIMt-1 into components, and match and connect the components with the engineering details; S2-3, expand all information generated and summarized from the component model up to the end of the previous stage, including engineering-related information of the design stage, procurement stage, and construction t-1 and all previous sub-stages.

[0007] In S2, real-time integration and updating of multiple information includes: S2-4, obtaining multiple real-time information of the construction sub-stage t, the acquisition method of which includes but is not limited to IoT sensing, measurement monitoring and adjustment and deployment methods; S2-5, multiple real-time information is divided into progress, resources, quality and safety dimensions.

[0008] S2-6, the real-time information is integrated, updated, and stored with the historical information to obtain BIMt that integrates the information of the construction sub-stage t and all previous stages.

[0009] In S2-2, the engineering details are broken down to the required depth using the engineering sub-item method.

[0012] The main beneficial effects of the present invention are: Compared with the traditional extensive management method, which is only for the purpose of achieving a certain set goal, lacks systematic process and operation mechanism, and lacks long-term planning, the present invention forms a refined management method with clear operation process, reasonable operation mechanism, quantitative management indicators, and iterative information update. The present invention embodies the driving mechanism of BIM and multi-information in project management: By collecting, integrating and updating real-time data, the passive driving of construction management by external events is achieved.

[0013] Through rules and algorithms, the information carried by BIM is automatically checked, monitored, and risk assessed, thus achieving active BIM-based management of the construction period.

The overall control information is accumulated, updated, transferred, interacted and shared in the device over time. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Figure 1 This is a flow chart of the refined management method for the construction period of an engineering project based on BIM multi-information integration and drive of the present invention.

[0017] Figure 2 It is a device block diagram of the present invention. DETAILED DESCRIPTION

[0018] like Figure 1~Figure 2 A method and device for fine management of engineering construction period based on BIM multi-information integration and driving includes the following steps: S1, the construction period is divided into T construction sub-stages, the current construction sub-stage is recorded as stage t, its previous sub-stage is t-1, and the next sub-stage is t+1; S2, for each sub-stage t, using the building information model as a carrier, the historical information is transmitted, and the real-time multi-information is integrated and updated to obtain the information model BIMt that integrates the construction information of the current sub-stage; S3, for BIMt, uses pre-defined indicator calculation rules and models, big data and artificial intelligence algorithms to conduct indicator evaluation and risk prediction on the information obtained at the current stage, and generate refined management and control plans; S4, in the next stage t+1, repeat the above process of S2~S3 to update and accumulate information.

[0019] Embodiment 1, like Figure 1 As shown, the specific implementation scheme of the refined management method for the construction period based on BIM multi-information integration and driving in the present invention is as follows: Step 1: Divide the construction phase into several construction sub-phases or key moments. The current construction sub-phase is recorded as sub-phase t, the previous sub-phase is recorded as t-1, and the next sub-phase is recorded as t+1. The corresponding BIMs with multi-information integration at the end of each phase are recorded as BIMt-1, BIMt, and BIMt+1 respectively.

[0020] Preferably, in an implementation scheme provided in this embodiment, the construction phase can be roughly divided into three sub-phases, namely: preparation sub-phase (t0), construction sub-phase (t1), and handover and defect liability sub-phase (t2); then according to the project requirements, the byte pairs can be further subdivided: the schedule is designed based on the project sub-items and contract progress requirements, and each progress task is attached to each more detailed sub-phase.

[0021] Specifically, the main activities of the preparation sub-phase include obtaining construction permits and information on relevant regulations and technical standards, selecting supervision units and subcontractors, signing construction contracts, organizing the review of drawings, compiling procedures, operating and explaining design and technical aspects, etc.; The implementation management of construction is the key work in the construction stage, including site management, resource management, progress management, cost management, quality management, and overall safety and civilized management; The main tasks of the Handover and Defect Liability sub-phase are project delivery, equipment and facility commissioning, completion material acceptance and property handover preparation.

[0022] Step 2: Decompose the project according to the sub-item rules, split the BIM model into components, and confirm the correspondence between the decomposed project details and BIM components, and then connect them.

[0023] In the implementation scheme provided in this embodiment, the project in step 2 can be decomposed with reference to the WBS code, and the decomposition depth should reach the depth of the inspection batch to meet the needs of refined management during the project construction period.

[0024] Step 3: In sub-phase t, obtain the integrated information model library BIMt-1 generated at the end of the previous sub-phase t-1, and extract and expand the information of BIMt-1 to obtain the design phase information, procurement phase information, construction sub-phase t-1 and its previous existing information.

[0025] In the implementation scheme provided in this embodiment, the reference information for the current construction sub-stage in step 3 is comprehensive information accumulated and integrated since the design stage. Compared with the traditional management model that can only refer to the construction stage information, this model can take advantage of the information accumulation of the entire process.

[0026] As shown in the following table, the information extracted and expanded in step 3 can be divided into three categories: general information, organization-specific information, and project-specific information:

[0027] Specifically, the general information category defines publicly available information about building products, regulations, standard procedures, the natural environment, etc.; Organization-specific information contains all the information available to a particular organization, such as standard solutions to design-construction problems, usually in the form of a library of previously completed projects that serve as reference cases within the organization and may include information related to similar projects; Project-specific information is related to a specific construction project or project type, but is shared by multiple organizations that make up the supply chain. In this embodiment, it involves the management of project-specific information during the actual construction phase of the project site, including general information, organizational information, construction management information, technical information, resource information, and environmental information.

[0028] Step 4: Further filter, classify and organize the information extracted and expanded from BIMt-1 in step 3, and organize the information according to the construction control dimension.

[0029] In the implementation scheme provided in this embodiment, the information sorting in step 4 is carried out according to the four dimensions of progress, resources (cost), quality, and safety. In different construction projects, the above four dimensions can be adjusted according to the actual information management and control needs.

[0030] Step 5: Obtain real-time construction information of stage t through manual measurement and monitoring, IoT device perception and monitoring, receiving external inquiries or adjustment requirements, and drive the dynamic integration and update of multiple information from BIMt-1 to BIMt.

[0031] In the implementation scheme provided in this embodiment, step 5 can be divided into the following steps 51-54: Step 51: For progress information, timely update the database of real-time construction progress, progress plan adjustment changes, etc., including but not limited to: the actual construction volume completed in the current stage, the overall completion degree of the component level, the subsequent construction progress planning, and the update of the construction section component information database; the received abnormalities such as progress lag should be controlled by the relevant management personnel; Step 52: For resource information, calculate the resource cost and update the database at the current stage based on the actual resource type, usage quantity, purchase price, and deployment status of the project construction site, including the actual allocation and use of relevant personnel, materials, equipment, etc.; update the corresponding plan data in a timely manner according to the adjustment and changes of the procurement and use plan; Step 53: For quality information, the quality monitoring database is updated in real time mainly based on manual measurement or IoT sensing methods; for abnormal values ​​in monitoring, an abnormal response is required to promote relevant management personnel to implement corresponding measures to correct abnormal behavior; Step 54: For security information, the security monitoring database is updated in real time based on manual measurement or IoT sensing; for security risk anomalies that occur, management personnel correct security behaviors.

[0032] Step 6: By formulating an indicator calculation rule base and utilizing advanced technologies such as big data and intelligent algorithms, automatic analysis, prediction, and decision-making of information at and up to the current stage can be achieved.

[0033] In the implementation scheme provided in this embodiment, step 6 can be divided into the following steps 61-64: Step 61: Automatically update the construction progress and schedule, and proactively check the matching degree between the current progress and the plan according to the time nodes of the construction plan; Step 62: Based on the actual cost statistics, compare the resource allocation plan, combine the macro cost control algorithm, and regularly evaluate the resource allocation plan and optimize resources; Step 63: Conduct periodic quality inspections on the inspection batches of the construction projects, automatically identify quality defects of the construction results through intelligent algorithms, actively predict potential quality risks in combination with the big database, and form a quality assessment report; Step 64: Conduct safety assessments and potential safety risk predictions regularly, and automatically generate emergency response plans based on the safety experience database.

[0034] Step 7: For the next construction sub-stage t+1, use the multi-information integrated model library BIMt generated at the end of sub-stage t as the initial information library carrier, repeat steps 1-6, integrate the real-time information of sub-stage t+1, drive the update and accumulation of construction information in the new stage, and realize semi-automatic refined management of the construction period.

[0035] In this embodiment, the BIM library at each construction sub-stage can establish information by extracting, expanding and integrating the BIM of the previous stage, and dynamically update new information in real time. By continuously repeating the above-mentioned process of information disassembly, information integration and updating, the engineering information gradually gathers around BIM, and finally forms a complete set of engineering construction information. Based on the above process, in the management system of actual application, the model of time information slices can be extracted and integrated at any time to query, adjust and share real-time data, and use big data and intelligent algorithms to automatically monitor, regulate and respond to abnormalities of multiple information of progress, resources, quality and safety through scheduled tasks, thereby realizing semi-automatic and refined management of the project.

[0036] Embodiment 2, Based on the refined management method of the construction period based on BIM multi-dimensional information integration and driving in Example 1, a visual refined management device or system of multi-dimensional elements of the construction period is realized, such as Figure 2As shown: Step 1: Data acquisition and transmission module, which mainly collects and updates real-time data through external measurement, sensor devices or manual methods.

[0037] Preferably, the sensor device data can be directly imported into the database via the Internet of Things, and the measured or manually modified information needs to be manually exported and sorted before entering into the database.

[0038] Step 2: The data base module consists of enterprise and storage servers or cloud servers, etc., and is used to store construction history and real-time multi-information data, BIM model data, system calculation or prediction data, etc.

[0039] Step 3: Backend module, which integrates application-related functions and algorithm call interfaces to process user requests, implement business logic, and optimize performance and security.

[0040] According to project requirements, the statistical methods and key indicators of information management in the dimensions of progress, resources, quality and safety, as well as the overall control model of information in each dimension are integrated into the management device or system.

[0041] According to the statistical methods and key indicators, the corresponding calculation rules are sorted out and pre-stored in the database for calling by the background interface.

[0042] For the overall control model, which mainly includes automatic analysis models such as risk prediction and abnormal response, it is necessary to organize the corresponding artificial intelligence, big data and other algorithms and embed them in the system background, and bind them to scheduled tasks for calling.

[0043] Step 4: Front-end module, which provides a user interface and visualization panel, mainly used to display BIM models with timelines, risk warning prompts, real-time monitoring and statistical charts. Specifically: Step 41: BIM model display area: The content includes the overall BIM model and the timeline based on the progress. The timeline is established according to the division of construction sub-phases and key time nodes, and is used to subsequently establish the time slice of project information during the construction period.

[0044] (1) Click on a specific component to zoom in on it and expand the detailed timeline; click on a moment on the timeline to expand multiple information options for the current component at that moment; click on each piece of information to expand and view detailed data and statistics, which can be displayed in the form of but not limited to reports, pictures, etc.

[0045] (2) Click on a moment on the timeline to obtain the overall multivariate information options for that moment; click on a component to view the multivariate information of the component at the current moment; click on each piece of information to expand and view detailed data and statistics, which can be displayed in the form of but not limited to reports, pictures, etc.

[0046] Step 42: Risk warning area: According to management needs, design automatic warning modules such as overdue warning, overspending warning, quality warning, and safety warning. It can be started by a scheduled task or manually triggered to update. Obtain relevant data through the background, call relevant warning models or algorithms for intelligent risk prediction, and return the prediction results to the front end for display.

[0047] Step 43: Real-time monitoring and statistics area: For the key measurement and monitoring indicators, automatically capture the data of the relevant time period, call the background calculation interface to perform statistics and calculations, and display them in the form of statistical charts by the front end.

[0048] In this embodiment, the BIM information flow framework described in Example 1 is embedded in the engineering management and control system, and the visual BIM library at each moment is conveniently retrieved through the timeline, and then expanded to form the construction information slice at that moment. The timeline continues to grow and is dynamically updated as the construction progresses; the BIM-based information slice provides managers with an accurate window under the macro process, and can clearly and intuitively provide managers with information reading, data aggregation and analysis functions, providing a feasible solution to the management problem of "the information generated by construction is different from the information required by managers" at different time nodes.

[0049] The advantage of the above method and device is that the mainstream research mainly focuses on the engineering management method and system research around BIM, without a detailed description of the role of BIM in the refined management of engineering, and without clarifying the specific driving factors in the management process. The present invention specifically embodies the driving role of BIM in project management, clarifies the passively driven external behavior factors and the actively driven internal behavior factors, and explains the role of each factor in the management process of multi-information, forming a set of driving mechanism methodology.

[0050] The information models in the current mainstream research are mainly designed for specific stages, specific management dimensions or information elements, which results in a lack of information and experience accumulation throughout the process, that is, it is difficult to call the information of the design and procurement stages during the construction stage, and it is impossible to take into account the multi-dimensional information management and control of progress, resources, quality, and safety. The present invention comprehensively considers the interaction between multiple information, considers the maximum active role that BIM can play under the conditions of multi-dimensional information coupling from a macro perspective, uses BIM as a high-quality visual information carrier, packages complex information for transmission, updating, and accumulation in time and space, and unfolds and presents the required information at the required time. And combining the above advantages has formed a set of time-series-based refined management devices for the construction period of the project, which can slice, archive, and call the model library containing complex construction information in time series, greatly improving the efficiency of project supervision.

[0051] The above-mentioned embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The embodiments and features in the embodiments of the present application can be arbitrarily combined with each other without conflict. The protection scope of the present invention shall be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
