[0066] Building Information Modeling (BIM) is a technology and tool widely used in the construction and engineering industry. It digitally integrates various information throughout the building design, construction, and operation processes. BIM systems not only provide comprehensive project information but also enable collaborative work at each stage, supporting project planning, design, construction, and operation. BIM systems have gained increasingly widespread application and recognition in recent years and have achieved a significant position in the construction industry.

[0067] However, design work requires extensive collaboration with various disciplines across different organizations, whether it's schematic design or construction drawing design, or general contracting or specialized design. Design habits also differ significantly between disciplines; for example, architects might use 3D modeling, while mechanical and electrical engineers might prefer 2D models. Therefore, to achieve collaborative design based on BIM technology, it's necessary to provide a collaborative platform that allows various disciplines to switch from traditional software design workflows to BIM design workflows.

[0068] Based on the above considerations, this application provides a BIM-based collaborative design method, applied to a BIM-based collaborative design platform, with the specific application environment as follows: Figure 1As shown in the diagram, terminal 102 communicates with server 104 via a network. The collaborative design platform based on the BIM system is stored on server 104, while the data storage system can store the data that the collaborative design platform based on the BIM system needs to process. The data storage system can be integrated on server 104 or placed on the cloud or other network servers. Server 104 obtains relevant modeling data uploaded by the terminals via the network, processes the modeling data accordingly, and then returns it to each local terminal via the network. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart vehicle devices, etc. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. Server 104 can be implemented using a standalone server or a server cluster composed of multiple servers.

[0069] like Figure 2 As shown, this application provides a BIM-based collaborative design method, applied to a BIM-based collaborative design platform, which includes the following method steps:

[0070] S201: Obtain a professional preliminary design model.

[0071] Specifically, the preliminary models completed by each discipline based on the project planning scheme are obtained. The preliminary design models of each discipline can be built directly on the BIM-based collaborative design platform through the platform's built-in database, or the model design can be completed on other software on the local terminal, the model file can be exported, and then uploaded to the collaborative design platform.

[0072] In a preferred embodiment, the files acquired by the collaborative platform are not limited to 3D modeling files; they can also be CAD design drawings. These CAD design drawings are then standardized according to drafting standards. A model conversion operation is performed on the CAD design drawings to obtain a BIM model containing drawing information, including component type, component parameters, and system coordinates. In other words, the CAD design drawings are used in the subsequent BIM model creation after conversion, thereby enabling professionals accustomed to using CAD for drafting to participate in BIM collaborative design. After generating the BIM model containing drawing information, the original CAD file is associated with this model as a supplement to the BIM model.

[0073] In a specific example, the disciplines include, but are not limited to, architecture, structural engineering, plumbing, HVAC, and electrical engineering. Taking the construction drawing design stage of the above-ground portion of a residential building as an example, the preliminary design model includes the following: Architectural modeling: the edges of the floor slabs on the changing floors, molding models, full-height windows and curtain walls, roof frames and curtain walls, K-pipes on each floor, partial lowering of the ground floor slab, confirmation of louvers at the basement air vents, confirmation of the ground floor electrical room, the elevation of the double-layer slab of the ventilation shaft, and modeling related to the integrated piping on the living balconies. Structural modeling includes: based on the architectural modeling and structural calculations, completing the modeling of structural walls, columns, and primary and secondary beams on each floor. Plumbing modeling includes: coordinating the location of water pipe shafts, roof rainwater drainage locations, modifications to the layout of fire hydrants and risers, the main horizontal trunk pipes in the elevated floor, riser locations, and related modeling of the integrated piping on the living balconies. HVAC modeling includes: the heating and ventilation fans on the ground floor and roof, adjustments and modifications to the positions of louvers on each floor, and modeling related to the integrated piping on the living balconies. Electrical engineers are also responsible for modeling the integrated piping system for the living balconies.

[0074] S202: Analyze the preliminary design model of the aforementioned profession to obtain the component model and design parameters.

[0075] After each discipline completes the model design on other software on their local terminals, exports the model file, and then uploads it to the collaborative design platform, the platform needs to parse and reconstruct the BIM model. Specifically, open-source software can be used to parse the uploaded file, reading the components and their attributes contained in the file, including but not limited to discipline, subsystem, component, attribute information, and attribute values. Among them, components are associated with the 3D model through coding, and attribute types include geometric parameters, location information, association information, and design parameters such as specifications.

[0076] S203: Generate a preliminary model based on the component model and the design parameters.

[0077] Based on the read file information, the BIM model is reconstructed to be expressed in the form of a structure tree. Simultaneously, the collaborative design platform stores the parsed component types and component design parameters, generating component databases for different disciplines according to attribute types.

[0078] S204: Based on preset parameters, perform conflict detection on the initial model and generate prompt information, wherein the conflict detection includes intra-professional conflict detection and inter-professional conflict detection.

[0079] Specifically, a 3D collision detection algorithm can be used to perform cross-disciplinary conflict detection on the initial model, identifying conflicts within the same discipline and between different disciplines and providing suggestions or reminders. For example, it can detect conflicts between disciplines such as curtain wall, landscape, municipal engineering, steel structure, architecture, structure, mechanical and electrical engineering, and interior decoration. In terms of specific conflict issues, it can detect them in real time, such as when walking through a transfer layer, the beam height increases, or the originally agreed-upon net height space for pipelines is insufficient.

[0080] S205: In response to the parameter modification operation by the relevant professionals, a first model is generated, wherein the first model is a collaborative design model determined based on the review and confirmation by the relevant professionals.

[0081] Relevant professionals access the collaborative platform to view component models and related design parameters, and also receive prompts generated by the platform after conflict detection. After fulfilling the coordination and review process for the civil engineering model, each discipline optimizes and adjusts the model, and the platform generates and stores verification records.

[0082] When relevant professionals need to modify the model portion under their responsibility, they can apply for modification permissions to directly modify components or their design parameters on the collaborative platform. Alternatively, they can export the BIM model, modify the exported file on their local terminal's modeling software, and then re-upload it to the collaborative platform to reconstruct the BIM model. Modification operations on the model will generate prompts and notify all relevant designers via messages.

[0083] In a preferred embodiment, considering that the conventional modeling process for architectural engineering generally involves initial model, intermediate model, and final model, which is a process of gradually improving the model, the collaborative design method for subsequent modeling also includes:

[0084] Based on the first model, an exportable first model file is generated; in response to the relevant professionals' detailed operation on the first model file, a professional detailed design model is obtained; based on the professional detailed design model, a detailed model is generated; in response to the relevant professionals' review operation on the detailed model, a second model is generated; based on the second model, a model performance analysis report is generated, wherein the performance analysis report is presented in a visual manner.

[0085] In a specific example, the second model is the intermediate model stage. It involves various disciplines, including but not limited to architecture, structural engineering, plumbing, HVAC, and electrical engineering. Taking the construction drawing design stage of the above-ground portion of a residential building as an example, the architectural modeling content in the intermediate model design includes: refining the model elevations, including the roof, the edges of the elevated floor, roof trusses, and canopies; providing wall views for each floor; numbering and indexing the initial model data and verifying sectional relationships; and confirming the modeling of the partial lower slab on the first floor. The structural engineering modeling content includes: based on the architectural intermediate model content, completing the arrangement and modification of structural walls, columns, and primary and secondary beams on each floor; designing floor slabs according to the lower slab elevation and thickness; and modeling the relevant double-layer slabs for the first-floor electrical room and ventilation shaft. The plumbing modeling content includes: completing the relevant modeling of the main horizontal pipes and risers in the elevated floor; and completing the relevant adjustments of the single-row and ventilation pipes on the second floor through 2D processing. The HVAC modeling content includes: adjusting and modifying the positions of the HVAC fans on the first floor and roof, and the louvers on each floor. Electrical engineers are also responsible for confirming the information on indoor distribution boxes and home wiring boxes, as well as modeling the main equipment in the elevator lobby.

[0086] Simultaneously, the platform's built-in performance analysis module can calculate performance indicators, including but not limited to, thermal radiation, site wind, indoor ventilation, lighting, and energy consumption, based on an intermediate model. This allows for targeted optimization of the current model based on the performance evaluation results.

[0087] In a preferred embodiment, after refining the intermediate model, the method further includes: generating an exportable second model file based on the second model; obtaining a professional final design model in response to a professional's refining operation on the second model file; generating a final model based on the professional final design model; generating a third model in response to a professional's review operation on the final model; and generating an auxiliary estimate of the engineering quantity based on the third model, wherein the auxiliary estimate of the engineering quantity is presented in a visual manner.

[0088] Specifically, the third model is the final model. Taking the construction drawing design stage of the above-ground part of a residential building as an example, in the final model design, the architectural profession is responsible for organizing and overlaying the model, adjusting the design based on the collaborative results of the intermediate model, reviewing and approving the model, and then completing the model according to the construction drawing BIM delivery standards. Other professions are responsible for adjusting the design based on the collaborative results of the intermediate model, reviewing and approving the model, and then completing the model according to the construction drawing BIM delivery standards.

[0089] Meanwhile, the platform's built-in auxiliary estimation module for engineering quantities can be used to perform auxiliary estimation of engineering quantities, thereby enabling the final model to be evaluated based on the engineering quantities and corresponding optimizations to be made based on the evaluation results.

[0090] This application provides a BIM-based collaborative design method. It acquires a preliminary design model for a specific discipline, analyzes the model to obtain component models and design parameters, generates a preliminary model based on these parameters, and then performs conflict detection on the preliminary model according to preset parameters, generating prompts. The conflict detection includes intra-discipline and inter-discipline conflict detection. Simultaneously, in response to parameter modification operations by relevant professionals, a final collaborative design model is generated after review and confirmation by these professionals. This application reconstructs the models of each discipline on a collaborative design platform to generate a BIM model usable for collaborative design, achieving positive multi-discipline collaborative design, significantly improving the efficiency of multi-discipline collaboration, and reducing design changes and modifications.
