Description

Technical Field

[0001] The present invention belongs to the technical field of BIM construction, and in particular relates to an integrated electromechanical installation construction method and system based on BIM. Background Art

[0002] In modern building construction, electromechanical installation is a key component, and its quality directly affects the overall performance and safety of the building. However, traditional electromechanical installation construction methods have many technical defects and are in urgent need of improvement.

[0003] First, the problem of information silos is widespread. Information in the design, construction, and management stages is often scattered across different teams and systems, resulting in poor data communication. This not only increases the complexity of information transmission, but also increases the probability of errors, ultimately leading to reduced construction efficiency and increased costs.

[0004] Secondly, insufficient construction accuracy is a significant problem. Traditional measurement and modeling methods may cause certain errors due to human factors or technical limitations, affecting the installation accuracy of mechanical and electrical pipelines. This inaccuracy will lead to many problems in the subsequent construction process, increasing the need for modification and adjustment.

[0005] Third, conflicts and coordination difficulties are common problems in mechanical and electrical installation construction. In complex building environments, conflicts between mechanical and electrical pipelines and building structures often occur. Traditional methods usually require multiple modifications on site, which not only wastes time but also increases resource consumption.

[0006] In addition, the delay in updating construction drawings is also a technical defect. Design changes frequently occur during the construction process, but traditional construction drawings often fail to reflect these changes in a timely manner, resulting in the actual situation on the construction site not being consistent with the drawings, increasing the risk of misunderstanding and errors.

[0007] Finally, the lack of scientific construction planning and collaborative management also restricted construction efficiency. The coordination between construction teams was often not close enough, resulting in a waste of resources and time. Traditional management methods made it difficult to achieve real-time progress tracking and dynamic adjustments, which affected the smooth progress of the entire project. Summary of the invention

[0052] Point cloud data provides high-precision on-site information, which can accurately reflect the actual situation of the building and help subsequent design and construction work; automatically generated point cloud data can significantly reduce the workload of manual measurement and reduce the risk of human error; through point cloud data, the building structure model can contain more details and information on existing facilities, enhancing the practicality and accuracy of the model; by directly processing point cloud data in the BIM environment, different teams can collaborate on the same platform, improve communication efficiency and reduce design conflicts; through visualized point cloud data, the construction team can have a deeper understanding of site conditions, formulate more reasonable construction plans and reduce risks.

[0053] The method of constructing the building structure model of the construction site in BIM software is: Set the thickness, height and material properties of the wall, and select the wall tool to automatically draw the wall based on the point cloud data; Set the actual height and level of the ground, and select the ground tool to automatically draw the ground at the bottom of the wall based on the point cloud data; Set the height and material of the ceiling and select the ceiling tool to automatically draw the ceiling on top of the wall based on the point cloud data; Set the type, size, and connection points of the pipeline, import existing electromechanical pipeline models, and automatically place electromechanical pipelines based on point cloud data.

[0054] The wall construction process involves setting the thickness, height and material properties of the wall, and using the corresponding wall tools to automatically draw the wall based on the point cloud data. For ground drawing, it is necessary to determine the actual height and flatness of the ground, and use the ground tools to automatically draw the ground at the bottom of the wall based on the point cloud data. As for the setting of the ceiling, it includes setting the height and material properties of the ceiling, selecting the ceiling tool, and automatically drawing the ceiling at the top of the wall based on the point cloud data. In terms of the placement of electromechanical pipelines, it is necessary to clarify the type, size and connection points of the pipelines, import the existing electromechanical pipeline model, and automatically layout the electromechanical pipelines based on the point cloud data.

[0055] The advantage of adopting this solution is its efficient modeling. Automated drawing greatly shortens the time required for manual modeling and quickly generates accurate models. Accurately match the on-site data and build the model directly based on the point cloud data to ensure a high degree of consistency between the model and the actual construction site. In terms of material and performance optimization, by setting material properties, suitable materials can be selected to improve building performance. Enhanced coordination is reflected in the integration of electromechanical pipeline models, which can better coordinate the building and electromechanical design and reduce potential conflicts. Improve construction efficiency. Through visual models, the construction team can understand the design intent more clearly, thereby improving construction efficiency and accuracy.

[0056] The method for generating new construction intervals for new mechanical and electrical pipelines and existing construction intervals for existing mechanical and electrical pipelines in the building structure model is as follows: According to the number, model and connection points of the new electromechanical pipelines, select the area tool to generate a new construction section, which includes the connection points of all new electromechanical pipelines; According to the types, sizes and connection points of the existing mechanical and electrical pipelines in the building structure model of the construction site, the area selection tool generates an existing construction section, which includes the connection points of all existing mechanical and electrical pipelines.

[0057] To create a new construction area: Based on the number, specifications and connection points of the newly added mechanical and electrical pipelines, use the regional tool to delineate a new construction area to ensure that the area fully covers the connection points of all new pipelines.

[0058] Build the existing construction area: According to the types, sizes and connection points of existing mechanical and electrical pipelines, use the area tool to construct the existing construction area to ensure that the area fully includes the connection points of all existing pipelines.

[0059] Clearly mark the construction areas of new and old pipelines to facilitate intuitive understanding and management by the project team; accurately delineate the construction areas to reduce conflicts between new and old pipelines and improve design coordination; through clear area divisions, the construction team can allocate resources and time more efficiently; integrate the information of new and old pipelines to facilitate subsequent maintenance and management; any design changes can be reflected in the model immediately to ensure the consistency and accuracy of information.

[0060] The method for generating the layout plan of new electromechanical pipelines based on the new construction section and the existing construction section is as follows: Confirm the scope of the new construction area in the building structure model, use the automatic layout algorithm to automatically layout the new mechanical and electrical pipelines in the new construction area, and generate layout plan 1; Confirm the scope of the existing construction area in the building structure model, use the automatic layout algorithm to automatically layout the new mechanical and electrical pipelines in the existing construction area, and generate layout plan 2; Confirm the scope of the new construction area in the building structure model and mark the overlap with the existing construction area; Delete the overlapping parts in the new construction section, use the automatic layout algorithm to automatically layout the new mechanical and electrical pipelines in the remaining section, and generate layout plan three.

[0061] Data collection phase: First, collect relevant data on new electromechanical pipelines, including their quantity, model, connection point location and other information.

[0062] Scoping phase: Define the boundaries of the new construction area in the building structural model to ensure that it can contain all new mechanical and electrical pipelines.

[0063] Algorithm application stage: Automatic layout algorithms (such as genetic algorithms, simulated annealing, etc.) are used to automatically layout new electromechanical pipelines within the designated interval to form layout plan 1. The algorithm will optimize the layout based on factors such as the pipeline's spatial requirements, direction, and connection requirements.

[0064] Existing construction section confirmation stage: Existing data assessment phase: Analyze the layout of existing mechanical and electrical pipelines, including their types, sizes and connection points.

[0065] Scope confirmation phase: Confirm the boundaries of the existing construction area in the building structure model to ensure that all existing pipelines are covered.

[0066] Layout plan generation stage: The automatic layout algorithm is also used to layout the new electromechanical pipelines within the existing construction area to form layout plan 2. This plan will take into account the existence of existing pipelines to avoid conflicts.

[0067] Overlapping area marking phase: Conflict detection phase: Use the conflict detection function of the BIM software to identify the overlapping areas between the new construction section and the existing construction section.

[0068] Overlapping area marking stage: Mark these overlapping parts in the model to facilitate subsequent processing and visualization.

[0069] Overlap removal phase: Construction section adjustment phase: Remove the overlapping parts of the marks in the new construction section to avoid laying out new and old pipelines in the same space.

[0070] Area redivision phase: ensure the validity and applicability of the remaining intervals and prepare for subsequent arrangements.

[0071] Arrangement plan three generation stage: Re-arrangement stage: In the remaining available space, the automatic layout algorithm is used again to arrange the new electromechanical pipelines to form layout plan 3. At this time, the algorithm will give priority to the available space and the rationality of the layout to ensure the optimal layout of the new pipelines.

[0072] The automatic layout algorithm can quickly calculate multiple layout plans, significantly improving efficiency and reducing the possibility of human error compared to manual design. By clearly dividing the construction intervals of new and old pipelines, it ensures that the new pipeline does not conflict with the existing pipeline during design, reducing the complexity of subsequent construction and maintenance. During the construction process, if the pipeline layout needs to be adjusted, it only needs to update the data and re-run the layout algorithm to quickly generate a new plan, demonstrating strong adaptability.

[0073] Through the visualization function of the building structure model, the team can intuitively view the relationship between new and old pipelines, ensuring information transparency during the design and construction stages; the precise interval division and the use of automatic layout algorithms can maximize the use of space resources, reduce material waste, and improve construction efficiency; through the building structure model, various professional teams (such as structure, mechanical and electrical, and architecture) can work together on the same platform, facilitating information sharing and communication, and improving the overall project management level.

[0074] The method of using the conflict detection in the BIM software and evaluating the compatibility score of the layout plan of the new mechanical and electrical pipelines based on the conflict detection results is as follows: In the BIM software, select the conflict detection tool and set the detection range and type; Enable conflict detection to automatically scan for potential conflicts between new mechanical and electrical pipelines and existing pipelines and building structures; Generate a conflict detection report listing all conflicts found and their location, type and severity; Each conflict is assessed and weighted based on its number, type and impact, including: Minor conflict - low priority, moderate conflict - medium priority, severe conflict - high priority; Based on the evaluation results, the compatibility score is calculated using the following formula; Compatibility score = 100 - \left( \sum \text{(conflict weight)} \right) Compatibility score = 100 − (∑(conflict weight)) Calculate the compatibility scores of layout plan 1, layout plan 2, and layout plan 3.

[0075] The method for generating and recording the optimal construction layout plan in the building structure model based on the compatibility score is as follows: Check the compatibility scores of all layout options and identify the highest scoring option as a preliminary candidate; For candidate solutions, further optimize design parameters, including pipeline directions, connection points and support methods, to improve compatibility; Compare various plans in BIM software and obtain the optimal layout plan based on the compatibility score.

[0076] Ensure that the compatibility scores of all layout options have been calculated and recorded in the BIM software. Each option should list the conflict type, location and its corresponding score in detail.

[0077] Sort all the proposals according to their scores and select the one with the highest score as the preliminary candidate. Record the detailed information of the proposal, including its design drawings and relevant parameters.

[0078] Conduct in-depth discussions on the design details of the candidate solutions to identify specific parameters that need to be improved, such as: Pipeline layout: Consider adjusting pipeline routes to reduce crossing or overlapping areas.

[0079] Connect nodes: Evaluate connection methods and prioritize simplified designs to reduce potential conflict risks.

[0080] Support structure: Choose a more appropriate support scheme to avoid interference with other structures.

[0081] In the BIM software, the design parameters of the candidate solutions are gradually adjusted. After each adjustment, the conflict detection is re-executed and the changes in the compatibility score are recorded.

[0082] Evaluate the impact of each adjustment to ensure that the optimization direction will help improve the compatibility score.

[0083] Compare all optimized solutions, including preliminary candidate solutions and other solutions. Use the comparison function of BIM software to visualize the compatibility scores of each solution.

[0084] On the basis of the compatibility score, it is also necessary to consider factors such as construction difficulty, cost budget, construction period, etc. to conduct a comprehensive evaluation of the scheme. The weighted average method can be used to comprehensively consider multiple factors to ensure that the final selected scheme performs well in all aspects.

[0085] Based on the comprehensive evaluation results, select the optimal layout solution with the highest compatibility score and meeting other requirements; record all design parameters of the optimal solution in detail in the building structure model, including modification records, optimization process and final compatibility score. Ensure that the solution is archived for future reference; the systematic approach can quickly identify the optimal solution and shorten the time required for the design phase.

[0086] By optimizing the design in advance, possible conflicts and rework rates during the construction process can be reduced; selecting the best solution can effectively reduce material waste and construction workers' time investment, thereby saving project costs; scientifically evaluated and optimized solutions can ensure the feasibility and overall quality of construction; the sharing characteristics of the building structure model enable different professional teams to view the best solution in real time, promoting cross-departmental collaboration and communication.
