Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a MiMEP construction method and system based on BIM technology. Background Art

[0052] An embodiment of the present invention proposes a MiMEP construction method based on BIM technology. MiMEP uses BIM technology for design, factory prefabrication, and on-site assembly.

Instead, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0054] Example 1

[0055] The embodiment of the present invention provides a MiMEP construction method based on BIM technology, such as Figure 1 As shown, the method is applied to the field of modular construction, including:

[0056] S11. Upon receiving the preliminary design drawing corresponding to the target building input by the user, performing a comprehensive pipeline in-depth design based on a pre-set three-dimensional database to obtain a first BIM module corresponding to the target building and design requirements corresponding to the first BIM module;

[0057] The first BIM module is a mechanical and electrical pipeline structure model corresponding to the target building;

[0058] S12. When receiving the on-site data corresponding to the target building input by the user, split the first BIM module into at least one MiMEP sub-module according to the on-site data, each MiMEP sub-module having corresponding design requirements;

[0059] S13. When a review instruction input by the user is received, the size of each MiMEP submodule is reviewed according to the field data to obtain a corresponding review result;

[0061] S14. When the module test results input by the user are received, the assembly construction drawings corresponding to the target building are output according to the module test results and the design requirements corresponding to each MiMEP sub-module to guide the on-site assembly of the target building.

[0062] Among them, MiMEP (Multi-trade Integrated MEP, multi-disciplinary integrated mechanical and electrical), MiMEP structure such as Figure 2 This is a mechanical and electrical assembly technology. Its core concept is to fully consider manufacturing and assembly requirements during the design phase, thereby achieving excellent manufacturability and prefabricated installation. By transferring on-site material processing and cross-disciplinary construction work to factories for industrialized assembly, this technology is transforming the construction industry from a traditional model to an industrialized one.

[0063] The development of MiMEP represents the future trend of building industrialization, and promotes the transformation from traditional construction mode to a new construction concept of "building houses like building cars".

[0064] An embodiment of the present invention provides a MiMEP construction method based on BIM technology. MiMEP uses BIM technology for design, factory prefabrication, and on-site assembly. Compared with existing technologies, it achieves efficient construction, standardized production, green construction, and intelligent collaboration, promoting the development of the construction industry towards industrialization, greening, and intelligence, significantly improving quality, shortening construction period, and reducing costs.

[0065] Example 2

[0066] This embodiment provides a MiMEP construction method based on BIM technology, such as Figure 3 As shown in the figure, through factory prefabrication and modular assembly, complex electromechanical systems are broken down into standardized modules, and assembly line production is achieved like the production of automobile parts, ultimately achieving a high-efficiency, high-quality industrialized construction model. The method specifically includes:

[0067] Full professional modeling:

[0068] Use BIM technology to conduct one-to-one modeling of all relevant disciplines involved in electromechanical pipelines (such as HVAC, water supply and drainage, electrical, etc.) and build a three-dimensional database; the model in the three-dimensional database includes all details such as materials, components, valves, etc. to ensure high consistency with the actual installation, that is, the three-dimensional database includes at least one electromechanical pipeline component and the model parameters corresponding to each electromechanical pipeline component.

[0069] Full professional modeling:

[0070] Comprehensive pipeline design: Based on the needs of the target building (i.e. reading the preliminary design drawings and analyzing the needs), a MiMEP plan is formulated, and comprehensive pipeline design is carried out on the BIM platform to optimize the pipeline layout, avoid spatial conflicts, and ensure coordination between various disciplines.

[0071] Based on the in-depth design of the pipeline system, a complete BIM model (i.e. the first BIM module) is generated to clarify the location and installation process of each mechanical and electrical pipeline component.

[0072] Pipeline integrated design (PIDE) refers to the detailed design process for integrated piping. This process is primarily used in construction projects, particularly in mechanical and electrical installations, and involves designing the piping and wiring layout for multiple systems, including plumbing, heating, ventilation, and air conditioning (HVAC), and electrical. Its goal is to address spatial layout issues between specialized systems through meticulous design planning, ensuring that all piping and wiring can be rationally arranged within a limited space, avoiding conflicts and interference, and meeting construction and maintenance requirements.

[0073] Module design: Based on the in-depth design of the pipeline system and combined with the on-site data of the construction site, the designed first BIM module is divided into multiple MiMEP sub-modules. Each MiMEP sub-module is a complete electromechanical pipeline module.

[0074] Subsequently, pipeline optimization, bracket optimization, and unique coding are performed on the electromechanical pipeline components and other contents within each MiMEP sub-module to form a modular management standard.

[0075] Also, review and feedback based on on-site dimensions.

[0076] Factory stage:

[0077] Material processing: According to the design requirements of each MiMEP sub-module in the BIM module (i.e. deepening the design and outputting the MiMEP sub-module processing list), the cutting, processing and supporting preparation of pipes, accessories, etc. are completed in the factory.

[0078] Modular assembly: The processed pipelines and components (electromechanical pipeline components) are modularly assembled in the factory to achieve standardized production; each MiMEP sub-module is strictly assembled according to the design code (unique code) to ensure compliance with design requirements.

[0079] Pre-assembly and quality inspection: After the sub-modules are assembled, pre-assembly verification is carried out, dimensional review and feedback are conducted, and the matching of module interfaces, dimensions and functions is checked to ensure the high precision and reliability of modular assembly. After passing the quality inspection, the prefabricated construction drawings and technical instructions of the MiMEP sub-modules are output, and the transportation preparation stage is carried out.

[0080] On-site stage:

[0081] Module transportation: The pre-assembled modules are transported to the construction site and stacked according to the module coding and installation plan.

[0082] Modular installation: Modules are quickly assembled on-site according to the designed positions, reducing the workload and complexity of on-site work. This is carried out simultaneously with civil construction, optimizing the construction process and significantly improving the overall construction speed.

[0083] The embodiment of the present invention provides a MiMEP construction method based on BIM technology. It adopts synchronous operation, that is, factory prefabrication and building structure construction are carried out simultaneously, which greatly shortens the on-site construction time. The advanced modular design reduces the on-site processing and assembly processes, making the mechanical and electrical installation more efficient. The precise design and factory processing achieved by BIM technology ensure the high consistency of module size and performance, avoiding on-site errors. The modules are pre-assembled and quality-tested in the factory, reducing the problem of inconsistent construction quality caused by differences in workers' technical levels. Modular management implements unified standards to ensure the integrity and consistency of the installation. Factory production controls processing accuracy, optimizes material utilization, and reduces material waste. Factory prefabrication reduces on-site labor input and reduces dependence on highly skilled workers. Due to the significantly shortened construction period, the overall project cost (such as equipment rental and management fees) is also reduced. The modules are assembled in the factory, and only splicing and installation are required on-site, which greatly reduces the heavy on-site work. Modular construction reduces cross-operation with other disciplines and improves the orderliness of the construction site. It also reduces high-altitude and complex operations on site, reducing construction safety risks. Factory production reduces dust, noise, and waste emissions at construction sites, in line with the concept of green building; modular design optimizes material use, supports recycling, and promotes sustainable building development. The all-in-one design based on BIM technology eliminates spatial conflicts in traditional construction and improves the efficiency of collaboration among various disciplines; modular design unifies coding and standards, making multi-disciplinary collaboration more efficient and reducing rework and design changes. MiMEP's modular construction method realizes the industrialization and standardization of the construction process, promoting the transformation of the construction industry from the traditional construction model to the industrialized model of "factory production and on-site assembly"; combining BIM technology with intelligent manufacturing technology, it lays the foundation for intelligent building construction.

[0084] Example 3

[0085] This embodiment provides a MiMEP construction method based on BIM technology, including:

[0086] S10, obtaining a function block corresponding to each electromechanical pipeline component based on the received at least one electromechanical pipeline component and the model parameters corresponding to each electromechanical pipeline component, and a preset model interface;

[0087] A 3D database is configured based on the functional blocks corresponding to each electromechanical pipeline component and predefined functional block interfaces. These functional block interfaces adhere to the gRPC framework and support cross-platform calls. Data exchange uses the JSON-LD format, embedding IFC entity-relationship semantics. When integrated with ERP systems, event-driven asynchronous communication is implemented through Apache Kafka, ensuring a concurrent processing capacity of over 2,000 transactions per second.

[0088] and, visualizing the corresponding functional blocks in the form of single graphic elements according to the model parameters of the electromechanical pipeline components mapped to each functional block;

[0089] The graphic element corresponding to each visualized function block displays the name and model parameters of the electromechanical pipeline mapped by the function block;

[0090] The three-dimensional database includes at least one configured functional block, and each functional block maps the corresponding electromechanical pipeline component and the model parameters of the electromechanical pipeline component. Generally, the three-dimensional database is constructed using the Industry Foundation Classes (IFC) standard, and each electromechanical pipeline component is dynamically modeled through a parametric template. Each component contains the following metadata: material properties (density, thermal conductivity, etc.), geometric parameters (pipe diameter, bending radius, etc.), interface specifications (flange standard, thread type, etc.) and installation tolerances. The database uses SQLite to implement relational data storage, establish a mapping relationship between components and functional blocks, and support real-time data synchronization based on the OPC UA protocol.

[0091] Furthermore, the various electromechanical pipeline mechanisms may be classified according to their corresponding functions, for example, they may be classified according to system type (water supply and drainage, electrical, etc.), installation location or functional characteristics, etc., to facilitate quick retrieval or use.

[0092] Furthermore, automated tools are introduced to automatically generate interface documentation, reducing the workload of manual editing and improving accuracy. At the same time, open standard interfaces such as IFC (Industry Foundation Classes) are adopted to enhance compatibility with other systems.

[0093] S11. When the preliminary design drawings corresponding to the target building input by the user are received, a second BIM module of the target building is constructed according to the preliminary design drawings. Specifically, an automatic recognition algorithm can be used to identify key information in the preliminary design drawings, such as using an image recognition algorithm (based on YOLO target detection) to identify the electromechanical pipeline components in the preliminary design drawings, and generate a list of electromechanical pipeline components (the list includes the names of the electromechanical pipeline components identified in the preliminary design drawings), which facilitates BIM modeling and comprehensive in-depth design of pipelines, reduces the workload of manual input and reduces the error rate.

[0094] And, according to the preliminary design drawings, the corresponding functional blocks are called one by one from the first preset area and placed in the second preset area to carry out the comprehensive in-depth design of the pipeline and obtain the corresponding first BIM module; that is, based on the call instructions received from the user input, the electromechanical pipeline mechanism is called from the area where the three-dimensional database is located, and the comprehensive in-depth design of the pipeline is carried out in the second preset area.

[0095] Obtaining design requirements corresponding to the first BIM module based on model parameters corresponding to each electromechanical pipeline component in the three-dimensional database;

[0096] The second BIM module includes the first BIM module and at least one electromechanical pipeline component;

[0097] The first preset area is a three-dimensional database area; the second preset area is a first BIM module design area.

[0098] S12. When receiving the on-site data corresponding to the construction site input by the user, split the first BIM module into at least one MiMEP sub-module based on the on-site data and the design requirements corresponding to the first BIM module, as well as the model parameters corresponding to the electromechanical pipeline components in the first BIM module, wherein each MiMEP sub-module is a complete standardized module and each MiMEP sub-module has corresponding design requirements;

[0099] Furthermore, according to a preset coding strategy, all electromechanical pipeline components in each MiMEP submodule are uniquely coded to obtain a design code corresponding to each electromechanical pipeline component.

[0100] Specifically, the field data is relevant data collected from the construction site, namely, relevant data of the target building (including structural conditions, location of temporary facilities, etc.) collected by sensors pre-installed at the construction site, as well as various dimensions and other contents collected by on-site collection equipment. This field data is transmitted to the central equipment for processing at preset intervals through local equipment installed at the construction site. The central equipment determines which parts can be processed as independent working units or submodules based on the field data. For example, certain areas may require special design due to space constraints, or certain systems (such as water supply and drainage, electrical, etc.) need to be considered independently. Furthermore, the field data is stored and updated in real time.

[0101] During the splitting process, MiMEP submodules are typically implemented based on a pre-stored splitting strategy. This strategy, typically established before implementation based on project conditions, preliminary design drawings, and engineering requirements (e.g., regarding complexity, construction sequence, and logistics), defines a set of clear splitting criteria. For example, MiMEP submodules can be divided based on system type (plumbing, electrical, HVAC), functional area, or floor level. This strategy ensures that each MiMEP submodule is a complete, standardized module, containing all necessary components and information for easy prefabrication and on-site installation.

[0102] Furthermore, the entire splitting process and results are monitored in real time, and corresponding log information is generated to record the specific content of each sub-module and its design requirements.

[0103] Furthermore, all electromechanical pipeline components in each MiMEP submodule are uniquely coded according to the pre-set coding strategy. The coding rules should take into account the type, location, size and other attributes of the pipeline to ensure that each code is unique. The codes are usually generated in batches through automated tools or scripts and associated with the corresponding electromechanical pipeline components. Furthermore, the coding rule adopts a segmented structure similar to: MEP-{system code}-{floor}-{serial number}-{version representation}. The system code follows the ISO 12006-2 standard, and the serial number generates a unique identifier using the SHA-256 hash algorithm. The coding automation tool is developed based on Python and integrated into the Revit API to automatically assign codes after component selection and generate a traceable CSV format bill of materials.

[0104] S13. When a review instruction input by the user is received, the size of each MiMEP submodule is reviewed according to the field data to obtain a corresponding review result;

[0105] When the review is passed, based on the design requirements of each MiMEP sub-module and the design code corresponding to each electromechanical pipeline component in each MiMEP sub-module, a processing list for each MiMEP sub-module is output to assist the factory in prefabrication and testing of the MiMEP sub-module.

[0106] Specifically, upon receiving a user-input review instruction, the system automatically compares and analyzes the latest pre-stored on-site data (such as actual space dimensions and temporary facility locations) with the design parameters of each MiMEP submodule using BIM software or specially developed tools. This includes, but is not limited to, key dimensions such as pipe diameter, length, and elbow angle. Furthermore, it automatically checks for any physical conflicts or mismatches, such as whether the actual installation path of a pipe collides with other structural elements.

[0107] Based on the review results, a corresponding review result is generated, typically in the form of a review report. If the review result indicates no issues, the MiMEP submodule is marked as "review passed." If there are any issues, the specific issues are recorded and an alarm is issued to notify relevant personnel to make adjustments.

[0108] Once reviewed, extract relevant information from the design requirements of each MiMEP submodule, including material specifications, quantity, location, and production process requirements. Ensure that the design code for each electromechanical pipeline component is correctly included in the process list for easy tracking and management. Use pre-configured automated tools or scripts to automatically generate a detailed process list based on this information. The list should include, but is not limited to, the specific dimensions and material specifications of each electromechanical pipeline component, the required quantity and batch, the specific location of the electromechanical pipeline component, any special process requirements, and installation instructions.

[0109] S14. Upon receiving the module test results input by the user, outputting the assembly construction drawings corresponding to the target building and the design codes corresponding to each electromechanical pipeline component in all MiMEP submodules according to the module test results and the design requirements corresponding to each MiMEP submodule;

[0110] And, pre-assemble each MiMEP module according to the assembly construction drawings and pre-set transportation capacity.

[0111] Furthermore, the S11 also includes introducing a dynamic conflict weight optimization model to adjust pipeline layout priorities in real time through a machine learning algorithm, thereby optimizing the layout of multi-professional pipeline spaces. Specifically, it includes:

[0112] First, set up the conflict detection function and define the minimum safe distance d between pipelines. min , real-time detection of pipeline spacing to see if it meets:

[0113]

[0114] Among them, P i and P n is the pipeline coordinate, and n is the number of pipelines.

[0115] Then, dynamic weight allocation is performed: a neural network model is trained based on historical construction data to output the weight wk corresponding to each electromechanical pipeline component (such as HVAC weight wHVAC, electrical weight wElec). The optimization objective function is:

[0116]

[0117] Among them, α is the preset length penalty coefficient, and Total_Length is the total length of all electromechanical pipeline components.

Compared with existing technologies, it achieves efficient construction, standardized production, green construction, and intelligent collaboration, promoting the development of the construction industry towards industrialization, greening, and intelligence, significantly improving quality, shortening construction period, and reducing costs.
