[0060] Combine Figure 1 As shown, the present invention provides a steel bridge manufacturing and installation management system based on BIM technology, including:

[0061] A tool set unit is used to construct a BIM model of a steel bridge through a parametric modeling plug-in, and to generate process drawings and bills of quantities based on the BIM model.

[0062] Specifically, the toolset unit constructs a BIM model (Building Information Modeling) of the steel bridge through a parametric modeling plug-in, and generates process drawings and quantity lists based on the model. Parametric modeling technology is used to quickly and efficiently create high-precision three-dimensional models. At the same time, process drawings and quantity information can be extracted from the model through automated tools. The use of the toolset unit not only greatly improves modeling efficiency, but also ensures the accuracy and consistency of drawings and quantity data, providing a solid data foundation for subsequent manufacturing and installation stages, and reducing construction delays and cost increases caused by design errors or inaccurate data.

[0063] The process design unit is used to perform process analysis based on the process drawings and the bill of quantities through a project management template to obtain multiple management plans for the steel bridge in the manufacturing stage.

[0064] Specifically, the process design unit utilizes project management templates, combined with process drawings and bills of quantities, to conduct a streamlined analysis and generate multiple management plans for the steel bridge fabrication phase. In a preferred embodiment of the present invention, using standardized project management templates, the unit is able to break down complex fabrication plans into multiple management plans, clearly defining the timelines, responsible individuals, and delivery standards for each management plan. This streamlined analysis approach not only improves process design efficiency but also ensures the scientific nature and enforceability of management plans, providing clear guidance for the smooth implementation of the fabrication phase and optimizing the overall manufacturing process.

[0065] A simulation unit is used to perform a processing and manufacturing simulation according to the management plan of the manufacturing stage, and to determine whether the management plan of the manufacturing stage meets the production requirements according to the simulation results of the processing and manufacturing simulation.

[0066] Specifically, the simulation unit performs processing and manufacturing simulation according to the management plan of the manufacturing stage, and evaluates whether the management plan meets the production requirements through the simulation results. In a preferred embodiment of the present invention, the simulation unit uses the BIM model and related data to perform virtual simulation of each link in the manufacturing process (such as cutting, welding, assembly, etc.) to discover potential production problems in advance (such as unreasonable resource allocation, process flow conflicts, etc.). Optimization suggestions based on simulation results can effectively adjust the management plan, ensure the efficiency and rationality of the production process, and reduce the risk of construction delays and cost overruns caused by unreasonable plans.

[0067] The installation management unit is used to generate multiple management plans for the steel bridge in the installation stage according to the management plan in the manufacturing stage when the management plan in the manufacturing stage meets the production requirements.

[0068] Specifically, once the fabrication phase's management plan meets production requirements, the installation management unit generates multiple management plans for the steel bridge installation phase based on that plan. This unit translates the fabrication phase's achievements into specific tasks for the installation phase, including scheduling, resource allocation, quality control, and safety management. This unit effectively manages the progress, quality, and safety of the installation phase. Through a digital platform, refined management of the installation process ensures efficient execution of installation tasks. Furthermore, the installation management unit monitors installation progress and quality in real time, adjusting plans promptly to address on-site changes, thereby improving management and project quality during the installation phase.

[0069] A delivery unit is used to deliver the steel bridge according to the management plan during the manufacturing stage and the installation stage.

[0070] Specifically, the delivery unit completed the final project delivery based on the management plan for the steel bridge's fabrication and installation phases. This unit ensured the integrity and consistency of data and results throughout the entire process, from design, fabrication, to installation. Through digital delivery, it enabled efficient management and sharing of project data. This delivery unit not only improved delivery efficiency but also provided accurate digital twin models and relevant data support for subsequent project operations and maintenance, enhancing the project's full lifecycle management capabilities.

[0071] The BIM-based steel bridge manufacturing and installation management system of the present invention, through its integrated toolset, process design, simulation, installation management, and delivery units, enables digital management of the entire steel bridge lifecycle, from the design, manufacturing, installation, and delivery phases. This significantly enhances the management capabilities of steel bridge manufacturing and installation. The toolset unit utilizes a parametric modeling plug-in to rapidly construct high-precision BIM models and automatically generates process drawings and bills of quantities, providing a precise data foundation for subsequent processes and significantly improving design efficiency and accuracy. The process design unit utilizes project management templates for process analysis and generates multiple management plans for the manufacturing phase, ensuring standardized and coordinated process design and optimizing the manufacturing process. The simulation unit performs simulation verification on the management plans to ensure they meet production requirements and guarantee their rationality and feasibility. The installation management unit generates detailed management plans for the installation phase based on the management plan for the manufacturing phase. The delivery unit ensures the complete delivery of project results, achieving a seamless transition from design to construction. This invention uses digital means to achieve refined control over the progress, quality, safety, and cost of steel bridge design, manufacturing, installation, and delivery, improving installation efficiency and quality. By using digital and intelligent means, efficient coordination and refined management of the entire process of steel bridge manufacturing and installation have been achieved, effectively reducing management costs, improving production efficiency and project quality, and enhancing the scientific nature and reliability of project management.

[0072] Optionally, the toolset unit is specifically configured to:

[0073] Obtaining basic parameters of the steel bridge;

[0074] Modeling and rendering the steel bridge according to the basic parameters using a parametric modeling plug-in to obtain an initial three-dimensional model of the steel bridge, and verifying the structure of the initial three-dimensional model;

[0075] The initial three-dimensional model that passes the verification is used as the BIM model of the steel bridge.

[0076] Specifically, the unit first acquires the basic parameters of the steel bridge, which generally include span, beam segment dimensions, cross-sectional shape, and connection methods. These parameters provide accurate input data for subsequent modeling. These parameters are the foundation for constructing a precise 3D model, ensuring that the model faithfully reflects the design intent and structural characteristics of the steel bridge. Secondly, a parametric modeling plug-in is used to model and render the steel bridge based on these basic parameters, generating an initial 3D model. The advantage of parametric modeling is that the model's size and shape can be quickly adjusted to accommodate varying design requirements, while reducing the complexity and error rate of manual modeling. After modeling is complete, the system verifies the structure of the initial 3D model, checking its geometric accuracy, component connection rationality, and compliance with design specifications. This verification process is critical to ensuring model quality, preventing subsequent manufacturing and installation issues caused by model errors. Only initial 3D models that pass verification are officially accepted as the BIM model of the steel bridge for subsequent process drawing generation, quantity calculations, and manufacturing and installation management. For example, in a steel bridge project, a parametric modeling plug-in was used to quickly generate high-precision steel beam and node models, which were then verified to meet design requirements, providing a reliable data foundation for subsequent manufacturing and installation.

[0077] In an embodiment of the present invention, by obtaining basic parameters and using a parametric modeling plug-in for modeling, the creation time of the three-dimensional model is greatly shortened, while the accuracy and consistency of the model are improved. The verification process further ensures the accuracy and compliance of the model, avoiding manufacturing delays and cost increases caused by design errors or model defects. Ultimately, the generated BIM model not only provides data support for the automated generation of process drawings and bills of quantities, but also lays a solid foundation for the digital management of the entire manufacturing and installation process, achieving seamless integration of design and manufacturing, and improving the overall management level and execution efficiency of the project.

[0078] Optionally, the toolset unit is further configured to:

[0079] Generate a processing drawing of the steel bridge according to the BIM model through an automated drawing plug-in, wherein the processing drawing includes a parts drawing, a rod drawing, and a total puzzle drawing of the steel bridge;

[0080] According to the basic parameters, the parts drawing, the rod drawing and the overall puzzle of the steel bridge are automatically annotated to obtain the process drawing of the steel bridge;

[0081] Perform feature extraction based on the BIM model to obtain geometric information and material information of the steel bridge;

[0082] The engineering quantity list is obtained by performing engineering quantity calculation based on the geometric information and the material information through an automated quantity calculation plug-in.

[0083] Specifically, the toolset unit is used to generate process drawings and bills of quantities for steel bridges. First, AI plug-ins, such as automated drawing plug-ins, are used to generate processing drawings for the steel bridge based on the BIM model, including part drawings, member drawings, and overall drawings. These drawings are crucial documents during the construction and manufacturing process, providing a visual representation of the steel bridge's structure and dimensions. In steel bridge projects, this invention leverages the 3D visualization advantages of the BIM model. The automated drawing plug-in can quickly generate various views, avoiding errors and omissions that may occur in traditional 2D drawings. Second, based on the basic parameters of the steel bridge, data is automatically annotated for the part drawings, member drawings, and overall drawings to produce process drawings. This process not only improves annotation efficiency but also ensures the accuracy and consistency of the annotated information, providing clear operational guidance for construction personnel. Feature extraction is performed using the BIM model. BIM software (such as Revit, ArchiCAD, Bentley, etc.) has powerful feature extraction capabilities. These software can directly extract the geometric and material information of the steel bridge from the 3D model. This information is the basis for quantity calculations. Finally, an automated quantity calculation plug-in was used to calculate quantities based on the extracted geometry and material information, generating a bill of quantities. This process reduced the tedious steps and errors associated with manual quantity calculations, improving the efficiency and accuracy of quantity calculations while providing a scientific basis for material procurement and cost control.

[0084] In this embodiment of the present invention, the automated drawing output plug-in generates processing drawings, combined with data annotation functionality to generate process drawings. This not only speeds up drawing generation but also reduces human error, ensuring the accuracy and consistency of the drawings. Furthermore, the BIM model's feature extraction and automated quantity calculation functions enable the rapid and accurate generation of bills of quantities, providing reliable data support for project management.

[0085] Optionally, the process design unit is specifically used to:

[0086] Selecting a management template corresponding to the steel bridge from the project management templates according to the bridge type and scale of the steel bridge;

[0087] By using the management template, a process analysis is performed based on the process drawings and the bill of quantities, and the manufacturing stage is divided into multiple subtasks;

[0088] Each of the subtasks is refined and reviewed to obtain a management plan for the subtask, wherein each subtask corresponds to a management plan.

[0089] Specifically, a management template matching the steel bridge type and scale (e.g., continuous beam, arch, suspension bridge, etc.) was first selected from a project management template library. These templates pre-set standardized process flows, timelines, and task allocations, ensuring standardized and consistent project management. Subsequently, the templates were used to decompose the complex manufacturing process into multiple subtasks, such as modeling, drawing generation, material procurement, and fabrication. Each subtask was clearly defined with responsible individuals, timelines, and deliverables to ensure scalability. Each subtask was then refined, including specific steps, required resources, and quality requirements, and then reviewed. This process not only ensured the completeness and accuracy of each subtask but also, through a review mechanism, prevented potential errors and omissions. Finally, a detailed management plan was generated for each subtask, providing clear guidance for the smooth implementation of the manufacturing phase.

[0090] In the embodiments of the present invention, by selecting appropriate management templates, the standardization and regularization of process design is ensured, reducing management confusion and schedule delays caused by human factors. The task decomposition and refinement process makes the complex manufacturing process clear and controllable. Each subtask has a clear responsible person and deadline, facilitating progress monitoring and resource allocation for project managers. The audit mechanism further ensures the quality of the management plan, preventing potential problems from being discovered during the implementation phase. Ultimately, these management plans provide a solid foundation for efficient execution during the manufacturing phase, ensuring the smooth progress of the steel bridge manufacturing process, reducing project risks, and improving overall management efficiency.

[0091] Optionally, the simulation unit is specifically used to:

[0092] Determining, according to the subtasks of the manufacturing stage, a production line model corresponding to the subtasks;

[0093] Determine the production schedule, resource input, and production line arrangement of each subtask based on the management plan of each subtask using the production line model;

[0094] Performing a manufacturing simulation based on the production schedule, resource input, and production line arrangement to obtain an estimated duration and delivery result for the subtask;

[0095] The estimated duration and the estimated delivery result are used as the simulation result of the subtask.

[0096] Specifically, a corresponding production line model is determined based on the nature and requirements of each subtask. For example, for a steel beam processing task, the simulation unit utilizes 3D models of the blanking, welding, and assembly lines. These models encompass not only the equipment layout but also the production process and process parameters. Next, based on each subtask's management plan, the simulation unit determines the production schedule, resource input, and production line arrangement. For example, for a complex steel beam welding task, the system schedules the use of welding equipment and the allocation of operators based on the timelines, resource allocation, and process requirements specified in the management plan. The system then performs a manufacturing simulation based on these schedules and resource allocations, calculating the estimated duration and delivery results for each subtask. This simulation can proactively identify potential production bottlenecks, resource conflicts, or delays, allowing for optimized adjustments to the production plan. Ultimately, these estimated durations and delivery results serve as the simulation results, providing a sound basis for subsequent production decisions.

[0097] In a preferred embodiment of the present invention, manufacturing simulation generally begins with defining the manufacturing simulation objectives, followed by collecting basic data, then constructing a simulation model. The model is then evaluated through simulation analysis, and finally, simulation optimization is performed based on the analysis results. During the simulation objective definition phase, the simulation objectives are clearly defined, such as verifying production capacity, identifying bottlenecks, and evaluating utilization. During the basic data collection phase, relevant data such as workshop layout, processes, orders, resources, logistics, failures, and quality are collected to provide the necessary input information for the simulation. During the simulation modeling phase, the collected data is used to define the layout, establish object models, set properties, create data tables, write scripts, and construct logistics, personnel, and resource models. During the simulation analysis phase, capacity, balance, equipment efficiency, logistics efficiency, personnel efficiency, resource efficiency, failure statistics, and maintenance efficiency are evaluated. Finally, during the simulation optimization phase, the analysis results are used to optimize layout reconfiguration, production sequence, buffer zones, logistics facilities, personnel, logistics routes, experimental design, and genetic algorithms. Simulation analysis reports are generated to guide the actual manufacturing process. This process not only improves production efficiency but also helps to identify and resolve potential production issues in advance.

[0098] In this embodiment of the present invention, simulation allows each subtask in the manufacturing phase to be fully verified in a virtual environment, enabling the early identification and resolution of potential issues, thereby avoiding production delays and resource waste caused by poor planning. Simulation can also optimize production scheduling and resource allocation, ensuring efficient production line operation and improving production efficiency.

[0099] Optionally, the simulation unit is further configured to:

[0100] Determining an estimated end time of the subtask based on the estimated duration of the subtask;

[0101] Comparing the estimated end time point with the expected end time point of the subtask;

[0102] If the estimated end time point is earlier than the expected end time point and the estimated delivery result meets the delivery standard of the steel bridge, then it is determined that the management plan of the subtask meets the production requirements;

[0103] If the estimated end time point is later than the expected end time point or the estimated delivery result does not meet the delivery standard of the steel bridge, it is determined that the management plan of the subtask does not meet production requirements.

[0104] Specifically, the simulation unit first determines the estimated end time for each subtask based on its estimated duration. This time, derived through manufacturing simulation, reflects the actual completion time given the current resource allocation and production schedule. The estimated end time is then compared with the subtask's expected end time. The expected end time is the ideal completion time set according to the overall project schedule and reflects the project management's intended goals. If the estimated end time is earlier than the expected end time and the expected delivery results meet the steel bridge's delivery standards, such as quality and quantity, then the subtask's management plan is deemed to meet production requirements. The specific delivery standards depend on the type and size of the steel bridge. This indicates that the current production schedule can not only complete the task on time but also ensure delivery quality. Conversely, if the estimated end time is later than the expected end time or the expected delivery results do not meet the delivery standards, then the management plan is deemed to be unsatisfactory.

[0105] For example, in the steel bridge manufacturing project in the preferred embodiment of the present invention, a subtask is steel beam welding, and its simulation results show that the expected completion time is one day earlier than the expected time, and the welding quality meets the standard, so it is judged that the management plan of this subtask meets the production requirements; while the expected completion time of another subtask, steel column processing, is later than the expected time, and some processing accuracy does not meet the standard, so it is judged that its management plan does not meet the production requirements and needs further optimization.

[0106] In this embodiment of the present invention, by comparing the estimated end time with the expected end time and conducting a comprehensive assessment based on the delivery standards, the feasibility of the management plan can be accurately determined. This verification method not only avoids delays and resource waste caused by unreasonable plans, but also ensures that the quality of the deliverables meets project requirements.

[0107] Optionally, the installation management unit is specifically configured to:

[0108] When the management plan of the manufacturing stage meets the production requirements, setting the progress requirements, quality requirements and installation requirements of each subtask in the installation stage according to the management plan of each subtask in the manufacturing stage;

[0109] The management plan for the subtask in the installation phase is generated according to the progress requirements, the quality requirements, and the installation requirements.

[0110] Specifically, after the management plan for the steel bridge fabrication phase meets production requirements, the installation management unit proceeds to detailed planning for the installation phase. Specifically, based on the management plan for each subtask in the fabrication phase, the installation management unit sets schedule requirements, quality requirements, and installation requirements for each subtask during the installation phase. These requirements are formulated based on the achievements of the fabrication phase and the actual conditions at the installation site to ensure a smooth installation process. For example, in a preferred embodiment of the present invention, a subtask involves steel beam machining, and its management plan for the fabrication phase has been verified through simulation to meet production requirements. During the installation phase, the installation management unit sets specific schedule requirements (such as hoisting schedules), quality requirements (such as welding quality standards), and installation requirements (such as hoisting equipment selection and operating specifications) based on the machining accuracy, dimensions, and installation location of the steel beams. Based on these requirements, the installation management unit generates a management plan for each subtask during the installation phase, clearly defining the execution details and timelines for the installation tasks, ensuring an efficient and quality-controlled installation process. This process not only takes into account the achievements of the fabrication phase but also incorporates the actual conditions at the installation site, providing a scientific basis for refined management during the installation phase. In a preferred embodiment of the present invention, the installation requirements also include camera installation requirements, such as specific interface connections of the camera.

[0111] In this embodiment of the present invention, by combining the management plan for the manufacturing phase with the specific requirements of the installation phase, the installation management unit can generate a detailed and targeted management plan to ensure the smooth execution of installation tasks. This refined management approach not only improves the controllability of the installation schedule but also ensures the quality and safety of the installation process through clear quality and installation requirements.

[0112] Optionally, the process design unit is further used to:

[0113] Obtaining the execution progress of all the subtasks in the manufacturing stage or the installation stage, and predicting the completion node of the subtask according to the execution progress to obtain a predicted completion node;

[0114] Determining the execution progress of the subtask according to the predicted completion node, wherein, when the execution progress lags behind, determining the resource configuration that needs to be changed for the subtask based on the lag of the subtask;

[0115] The management plan of the subtask is adjusted according to the resource configuration.

[0116] Specifically, by dynamically monitoring and predicting the execution progress of subtasks, real-time adjustments to the management plan are achieved. Specifically, the unit first obtains the execution progress of all subtasks during the manufacturing or installation phase. This progress data can be collected in real time via the installation management platform. Based on this progress data, the process design unit uses a data analysis algorithm to predict the subtask's completion point, obtaining a predicted completion point. In a preferred embodiment of the present invention, for example, if a subtask involves welding a steel beam, its actual execution progress indicates that the welding work is 60% complete, but the planned completion rate is 80%. Using the prediction algorithm, the system predicts that this subtask will lag behind the originally planned completion point. Based on the lag, the process design unit analyzes whether resource allocation is reasonable, such as insufficient welding equipment or inefficient welding personnel. Based on the analysis results, the system determines necessary resource allocation changes, such as increasing welding equipment or deploying skilled workers. Finally, based on the adjusted resource allocation, the process design unit readjusts the subtask's management plan to ensure the task is completed on time. This process demonstrates the dynamic and flexible nature of the process design unit in this embodiment, effectively addressing uncertainties in project execution. It's worth noting that predicting the progress of subtasks can be done by analyzing the relationship between the completion time and resource input of similar tasks in the past, such as in steel bridge projects, and building a regression model to predict the completion time of the current task. Alternatively, a random forest algorithm can be used to analyze the relationship between task progress, resource allocation, and environmental factors to predict task completion time. If historical data indicates that insufficient resources will cause progress delays, the model can automatically identify and issue an early warning.

[0118] Associating the management plan of the steel bridge in the manufacturing stage and the installation stage with the BIM model to obtain a digital twin model of the steel bridge;

[0119] The digital twin model is linked to the external documentation of the steel bridge and then digitally delivered.

[0120] Specifically, the delivery unit first associates the management plans for the manufacturing and installation phases with the BIM model to form a digital twin model of the steel bridge. The digital twin model not only contains three-dimensional geometric information, but also integrates management data such as progress, quality, and resources, realizing a deep integration of physical entities and digital models. The process drawings and quantity lists of the manufacturing phase, as well as the progress plans, quality records and other management data of the installation phase are linked one by one to the corresponding BIM model components. Subsequently, the delivery unit links the digital twin model with external documents of the steel bridge (such as design drawings, construction logs, acceptance reports, etc.). These documents are associated with specific components or tasks in the model through a coding system to ensure the traceability and integrity of the data. Finally, the integrated digital twin model and related documents are delivered to project stakeholders through the digital delivery platform to provide comprehensive digital support for subsequent operations and maintenance.

[0121] Combine Figure 2 As shown, in a preferred embodiment of the present invention, first, the design drawings are used to establish the BIM model of the steel bridge. Then, the BIM model is combined with external document data, and through collaborative management of process design, standardized project management templates, automatic review tools, model lightweight tools and data statistical analysis are used to optimize and manage the various subtasks of the manufacturing stage and generate a management plan for the manufacturing stage. Then, the management of the installation stage is implemented through modules such as camera connection interface, progress management, quality management and installation management to build a management plan for the installation stage to ensure the smooth progress of the installation process. Finally, the digital delivery of the steel bridge is completed through the automatic connection of the management plan and the model, forming a complete digital twin model to facilitate subsequent operation and maintenance. The entire process embodies the full life cycle management from design to delivery, emphasizing data integration, process collaboration and digital delivery to improve the management efficiency and quality of steel bridge projects.

[0122] Combine Figure 3 As shown, the present invention also provides a steel bridge manufacturing and installation management method based on BIM technology, comprising:

[0123] Build a BIM model of the steel bridge using a parametric modeling plug-in, and generate process drawings and bills of quantities based on the BIM model;

[0124] Through the project management template, a process analysis is performed based on the process drawings and the bill of quantities to obtain multiple management plans for the steel bridge during the manufacturing stage;

[0125] Performing a manufacturing simulation according to the management plan of the manufacturing stage, and determining whether the management plan of the manufacturing stage meets production requirements based on a simulation result of the manufacturing simulation;

[0126] When the management plan of the manufacturing stage meets the production requirements, generating multiple management plans of the steel bridge in the installation stage according to the management plan of the manufacturing stage;

[0127] The steel bridge is delivered according to the management plan during the fabrication phase and the installation phase.

[0128] Compared with the existing technology, the steel bridge manufacturing and installation management method based on BIM technology of the present invention has similar technical effects as the steel bridge manufacturing and installation management system based on BIM technology, which will not be repeated here.

[0129] Although the present invention is disclosed as above, the scope of protection disclosed by the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the scope of protection of the present invention.
