Description

Technical Field

[0001] This invention relates to the field of construction progress management technology, and in particular to a BIM-based method and system for managing the construction progress of hydropower projects. Background Technology

[0002] In traditional hydropower project construction schedule management, specialized project management software (such as P6 and MSP) is typically used to develop schedule plans, and BIM software is used separately for 3D modeling. However, these two systems are often independent, resulting in data fragmentation and a lack of visualization. The tasks in the schedule plan lack effective coding relationships with the components in the BIM model (such as dam sections, water diversion pipes, and unit foundations), making it impossible to accurately attach the time dimension to the 3D model. Furthermore, updates to the schedule status rely on manual reporting and comparison, making it difficult to display in the model in real time and intuitively, leading to delayed progress monitoring and making it difficult to detect deviations between the plan and the actual situation in a timely manner. Summary of the Invention

[0003] This invention provides a BIM-based method and system for managing the construction progress of hydropower projects, which addresses the shortcomings of heterogeneous data sources between the construction schedule plan and the BIM model in hydropower projects, such as the inability to automatically link and integrate them, low visibility of progress status, and delayed information feedback, resulting in poor efficiency in collaborative management of construction progress.

[0004] On the one hand, this invention provides a BIM-based method for managing the construction progress of hydropower projects, including:

[0005] Establish a mapping relationship between the construction schedule and the BIM model, bind the tasks in the construction schedule to the components in the BIM model through coding, and assign time attributes to the tasks;

[0006] Convert the BIM model to IFC format and export the construction schedule data;

[0007] The IFC format model is integrated with the exported construction schedule data and semantically matched to generate a 4D construction model with the time attribute.

[0008] The 4D construction model is loaded into a visualization environment, providing timeline control functionality and color-coding the corresponding components based on the task's execution status.

[0009] Establish a data interaction channel with mobile devices to push task information and visualized data to the site, and receive construction data feedback from the site.

[0010] According to the present invention, a BIM-based method for managing the construction progress of hydropower projects includes establishing a mapping relationship between the construction schedule and the BIM model, comprising:

[0011] Build task - component association database;

[0012] Match and map the task list exported from the project management software with the component numbers in the BIM model;

[0013] The successfully matched task-component pairs and their time attributes are stored in the associated database.

[0014] According to the present invention, a BIM-based method for managing the construction progress of hydropower projects includes converting the BIM model into IFC format and exporting the construction progress plan data, comprising:

[0015] Use the built-in IFC export interface of the BIM modeling software to export the complete model containing geometric and attribute information as an IFC file;

[0016] Using the reporting function of project management software, the task name, code, start time, end time, and person in charge information can be exported as a structured data file.

[0017] The IFC file and the structured data file are validated to ensure data integrity and consistency.

[0019] Parse the IFC format model file and extract the unique identifiers and geometric information of all components;

[0020] Read the exported construction schedule data and extract the code, planned start time, and planned end time for each construction task.

[0021] Based on the mapping relationship between the unique identifier of the component and the code of the construction task, the planned start time and planned end time of the construction task are dynamically assigned as new time attributes to the corresponding component.

[0022] All components with bound time attributes are reorganized and a 4D construction model that dynamically evolves along the timeline is generated in the visualization platform.

[0023] According to the BIM-based hydropower engineering construction progress management method provided by the present invention, the step of color-coding the display of corresponding components includes:

[0024] Based on the current timeline position, the system automatically compares the planned data to determine the task status of each component.

[0025] According to the preset color rules, components corresponding to tasks that have not started are rendered in gray, components corresponding to tasks that are in progress are rendered in yellow, and components corresponding to tasks that have been completed are rendered in green.

[0026] According to the BIM-based hydropower engineering construction progress management method provided by the present invention, the generation method of the preset color rules includes:

[0027] The user settings interface of the visualization environment provides a color configuration panel, allowing users to specify display colors for various states.

[0028] Use user-specified custom color schemes as color rules.

[0029] The BIM-based hydropower engineering construction progress management method provided by the present invention further includes:

[0030] The visualization interface provides an overlay comparison view of planned progress and actual progress;

[0031] Automatically detect whether there are conflicts in the current process logic or conflicts where multiple tasks compete for the same construction space;

[0032] When a conflict is detected, a warning is highlighted in the 4D construction model.

[0033] According to the present invention, a BIM-based hydropower engineering construction progress management method is provided, wherein establishing a data interaction channel with a mobile terminal includes:

[0034] Develop a mobile application that communicates with the backend management platform via API interfaces;

[0035] The backend management platform pushes task reminders and 3D illustrations to the designated mobile APP based on the calculation results of the 4D construction model.

[0036] The mobile app provides an interface for on-site personnel to upload construction photos, fill in the progress percentage, and record any problems encountered.

[0037] The BIM-based hydropower engineering construction progress management method provided by the present invention further includes:

[0038] Collect on-site construction data transmitted via the mobile app, including construction photos, progress percentages, and problem records;

[0039] Machine learning algorithms were used to analyze the construction photos, progress percentages, and problem records to identify potential risk patterns that could affect the project schedule.

[0040] Based on the aforementioned potential risk patterns, the total project duration is predicted, and a report recommending optimized construction sequence and resource allocation is generated.

[0044] The matching module is used to integrate and semantically match the IFC format model with the exported construction schedule data to generate a 4D construction model with the time attribute.

[0045] The display module is used to load the 4D construction model in the visualization environment, provide timeline control function, and distinguish and display the corresponding components by color based on the execution status of the task;

[0050] Beneficial effects

[0051] By binding tasks with component codes, the solution of this invention achieves automatic data integration and semantic matching from BIM software to 4D construction models, breaking down information silos and providing an accurate data foundation for dynamic simulation. Color-coded display of components based on the 4D construction model and task status makes the progress status of the entire hydropower project readily apparent, greatly improving the efficiency of progress analysis and the accuracy of decision-making. Through interactive channels, precise task instructions are issued and real-time on-site construction data is collected, ensuring timely updates and feedback on progress status. This forms a closed-loop management system from decision-making to execution and feedback, significantly improving the collaborative efficiency of on-site management of hydropower projects.

[0057] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0058] Figure 1 This is a flowchart illustrating the BIM-based hydropower engineering construction progress management method provided in this embodiment.

[0059] like Figure 1As shown in the figure, this embodiment provides a BIM-based method for managing the construction progress of hydropower projects, which mainly includes the following steps:

[0060] 101. Establish a mapping relationship between the construction schedule and the BIM model, bind the tasks in the construction schedule to the components in the BIM model through coding, and assign time attributes to the tasks.

[0061] Specifically, first, a task-component association database needs to be built. This database should support the storage of information such as task code, component number, task time attributes (start time, end time, duration), and task person in charge, and should be able to quickly query and match data.

[0062] Export all construction task lists from project management software (such as P6 or MSP), and extract the unique task code, task name, time attribute, and responsible person information for each task; at the same time, open the hydropower engineering BIM model in BIM modeling software (such as Revit), and extract the unique component number and component name of all components (such as dam section, water diversion pipe, unit foundation) in the model.

[0063] The exported task codes are bound one-to-one with the component numbers. The binding process can be confirmed manually or semi-automatically by using the interface plugin between BIM software and project management software. After the matching is completed, the task's time attribute, responsible person information and the corresponding component number are associated and stored in the task-component association database.

[0064] The system allows for setting up a status update trigger mechanism, enabling on-site managers to manually update task statuses such as "not started," "in progress," and "completed" through the backend management platform. It also allows for automatic updates of task statuses based on data feedback from subsequent mobile devices. The updated statuses are synchronized to the associated database and BIM model in real time.

[0065] By precisely linking construction tasks with BIM components, the information barriers between the two are broken down, providing accurate basic data for subsequent data integration and 4D construction model generation, while ensuring timely and synchronized updates to task status.

[0066] 102. Convert the BIM model to IFC format and export the construction schedule data.

[0067] Specifically, open BIM modeling software (such as Revit or Navisworks), call the software's built-in IFC export interface (such as the Revit IFC exporter), select the complete water and electricity engineering BIM model (including the geometric and attribute information of the components), set the export parameters (to ensure that key information such as component numbers and geometric dimensions are not lost), and export the model as an IFC standard format file.

[0068] Open the project management software (P6 or MSP), and use the software's built-in reporting function to select the schedule data fields you want to export, including task code, task name, start time, end time, duration, and responsible person. Export this data as a structured data file, such as XML or CSV format.

[0069] Perform data validation on the exported IFC file and structured data file: Use data validation tools to check whether the component number in the IFC file is unique and whether the geometric information is complete, and check whether the task code in the structured data file is duplicated and whether the time attribute is reasonable (such as the end time is not earlier than the start time). If data is missing or incorrect, return to the corresponding software to correct it and then re-export.

[0070] By converting data from different systems into a unified and compatible format, we can ensure data integrity and consistency, providing a qualified data source for the subsequent integration of IFC models and schedule data.

[0071] 103. Integrate and semantically match the IFC format model with the exported construction schedule data to generate a 4D construction model with time attributes.

[0072] Specifically, the data parsing tool is used to parse the IFC format file, extract the unique identifier (i.e., component number), geometric information (such as size and location), and basic attribute information (such as component type) of all components in the file, and temporarily store the parsing results in a temporary data pool.

[0073] The exported structured data file was read using a data reading tool, and the task code, planned start time, planned end time, duration, and person in charge information for each construction task were extracted and temporarily stored in a temporary data pool.

[0074] Based on the mapping relationship between task codes and component numbers in the temporary data pool, a semantic matching algorithm is used to dynamically assign the planned start time, planned end time, and duration of each task as new time attributes to the corresponding component.

[0075] By calling the model integration interface of a visualization platform (such as BIM 360), all components that have been bound to time attributes are re-integrated, and a 4D construction model is generated in the visualization platform. This model can support the display of the construction evolution process of the components in a time dimension.

[0076] By deeply integrating the IFC model with the schedule data, a 4D construction model with time attributes is generated, providing dynamic data support for subsequent visualization and progress analysis, and clearly presenting the time dimension of the construction process.

[0077] 104. Load the 4D construction model in the visualization environment, provide timeline control function, and display the corresponding components by color based on the execution status of the task.

[0078] Specifically, the generated 4D construction model is loaded into the visualization platform, and a time axis control component is set up. Users can view the construction status of the hydropower project at a specific time point by sliding the time axis slider or entering a specific time point, thus realizing a dynamic simulation display of the construction process.

[0079] Preset rules for the correspondence between task status and component color: The user settings interface of the visualization platform provides a color configuration panel, where users can customize the component display color corresponding to the three task statuses of "not started", "in progress" and "completed". The default rule is that unconstructed components are displayed in gray, components under construction are displayed in yellow, and completed components are displayed in green. The system automatically compares the planned data according to the current timeline position, determines the task status corresponding to each component, and renders the component color according to the preset rules.

[0080] Enable the progress comparison function to overlay the planned progress curve and the actual progress curve in the visualization interface. At the same time, use different colors to mark the components in the planned and actual states in the 4D construction model so that users can intuitively see the deviation between the two.

[0081] The conflict detection module is activated, and spatial analysis algorithms are used to detect potential spatial conflicts (such as overlapping construction spaces of two components), resource conflicts (such as multiple tasks competing for the same equipment), and process conflicts (such as subsequent tasks starting before the preceding task is completed). When a conflict is detected, the conflicting component is highlighted and flashed in the 4D model as a warning, and a conflict prompt message (including the conflict type, the task involved, and the component) pops up.

[0082] By visualizing and dynamically displaying the construction progress, the progress status is clear at a glance, making it easy for managers to quickly grasp the project progress, promptly identify progress deviations and construction conflicts, and improve the efficiency of progress analysis and the accuracy of decision-making.

[0083] 105. Establish a data interaction channel with mobile devices to push task information and visualized data to the site, and receive construction data feedback from the site.

[0084] Specifically, this involves developing mobile applications and setting up communication infrastructure.

[0085] Develop a dedicated mobile app that supports both Android and iOS systems and has functions such as task reception, data upload, message notification, and model viewing. It should also reserve an API communication interface for communication with the backend management platform.

[0086] The backend management platform and the mobile APP establish a communication connection through BIM 360API or a custom API interface to ensure the security and stability of data transmission and set up a data encryption transmission mechanism to prevent construction data leakage.

[0087] Based on the calculation results of the 4D construction model, the backend management platform filters the task information (such as task code, corresponding component, start time, and completion requirements) for each on-site construction worker, and attaches a 3D diagram of the component corresponding to the task. This information is then pushed to the designated construction worker's mobile APP via the API interface, triggering an APP message notification.

[0088] On-site data feedback and AI-assisted analysis.

[0089] After receiving tasks via a mobile app, on-site construction workers can upload photos and videos of the construction process, fill in the current task progress percentage (e.g., 30%, 70%), and record any problems encountered during construction (e.g., equipment failure, material shortage). The uploaded data will be transmitted back to the backend management platform in real time via a communication interface.

[0090] The backend management platform collects all on-site construction data (photos, progress percentages, and problem records) transmitted from mobile devices, and matches and associates this data with information in the task-component association database to update the actual progress status of the corresponding tasks.

[0091] Enable the auxiliary analysis module and use machine learning algorithms (such as decision tree algorithm and regression analysis algorithm) to conduct in-depth analysis on the returned construction photos (identifying construction quality and component completion status), progress percentage (analyzing progress deviations), and problem records (extracting key factors affecting the construction period) to identify potential construction delay risk patterns (such as frequent equipment failures during the construction of a certain type of component, leading to progress delays).

[0092] Based on the risk patterns derived from the analysis, the system predicts whether the overall construction period of the hydropower project will be delayed and automatically generates an optimization suggestion report. The report includes adjustments to the construction sequence, reasonable allocation of construction resources (such as increasing equipment investment in a certain area), and solutions to current problems. The report is also pushed to the backend management platform and mobile APP of the management personnel.

[0093] By collecting and feeding back on-site construction data in real time, a closed-loop management system of "decision-execution-feedback-optimization" is formed, which can promptly identify schedule risks and provide optimization solutions, significantly improving the collaborative efficiency and scientific nature of on-site management of hydropower projects.

[0094] Figure 2 This is a schematic diagram illustrating the effect of the BIM-based hydropower engineering construction progress management method provided in this embodiment.

[0095] The method described in this embodiment achieves automatic data integration and semantic matching from BIM software to the 4D construction model by binding tasks with component codes, breaking down information silos and providing an accurate data foundation for dynamic simulation. Color-coded display of components based on the 4D construction model and task status makes the progress status of the entire hydropower project readily apparent, greatly improving the efficiency of progress analysis and the accuracy of decision-making. Through the data interaction channel, precise task instructions are issued and real-time on-site construction data is collected, ensuring timely updates and feedback on progress status. This forms a closed-loop management system from decision-making to execution and feedback, significantly improving the collaborative efficiency of on-site management of hydropower projects.

[0100] The matching module 303 is used to integrate and semantically match the IFC format model with the exported construction schedule data to generate a 4D construction model with time attributes.

[0101] Display module 304 is used to load 4D construction models in a visualization environment, provide timeline control functions, and distinguish and display corresponding components by color based on the execution status of the task.

[0102] The communication module 305 is used to establish a data interaction channel with the mobile terminal, to push task information and visualized data to the site, and to receive construction data feedback from the site.
