[0056] See also Figure 1-2 , a BIM model creation method based on parametric technology.

[0057] Implementation method 1: Acquisition of construction project parameters

[0058] At the project start-up stage, the system obtains multi-dimensional parameter information of the construction project through various channels. These parameters include but are not limited to building form, spatial layout, building materials, structural form, climatic conditions, energy efficiency standards, acoustic performance, light environment requirements, etc. In order to ensure that the building model is highly consistent with the actual environment, the system collects environmental parameters of the construction site in real time through Internet of Things (IoT) sensors, such as temperature, humidity, wind speed and solar radiation. These data not only provide a solid foundation for optimizing building design, but also provide important references for subsequent construction stages to ensure the adaptability of buildings under different climatic and geographical conditions. In addition, the system will also obtain building specifications and regional planning data from relevant government departments to further ensure the legality and compliance of the design.

[0059] Implementation Method 2: Setting of Parameterized Rules

[0060] After collecting complete building project parameters, the system controls the model generation process by setting detailed parametric rules. The rules construct the relationship between design parameters through mathematical formulas, geometric relationships, and logical conditions. For example, the system will automatically set the relationship between building height and structural support system, window area and energy consumption standards, wall materials and sound insulation performance, etc. according to different building requirements.

[0061] In order to further improve the adaptability of the rules, the system introduces artificial intelligence (AI) algorithms to learn based on existing historical data of construction projects. By analyzing these historical data, AI can automatically generate preliminary design rules and continuously optimize these rules according to the specific needs of the project. For example, in the design of complex building structures, the system will learn the stress distribution and load characteristics of similar projects, so as to set reasonable support points and structural forms to ensure the stability and seismic performance of the building.

[0062] Implementation 3: Generate a parameterized model framework

[0063] According to the set parametric rules, the system automatically generates a preliminary framework for the building information model (BIM). This framework is constructed through a combination of parametric geometric components, including basic building elements such as walls, floor slabs, beams, columns, doors and windows. The model framework not only focuses on the appearance of the building, but also covers the functional layout of the interior space and the structural bearing system. For example, the system will automatically allocate appropriate beam and column cross-sectional dimensions according to floor height and load requirements to ensure the safety of the structure. In addition, the model framework also includes reserved locations for infrastructure such as energy systems, ventilation systems, and water supply and drainage systems, so that they can be optimized and adjusted in subsequent designs.

[0064] Implementation 4: Multi-level parameter optimization

[0065] After the initial model is generated, the system optimizes the parameters of each level in the model through multi-objective optimization algorithms. These algorithms include but are not limited to genetic algorithms, particle swarm algorithms, and Bayesian optimization algorithms. The optimization objectives are not only the rationality of the geometric structure, but also multiple factors such as material selection, energy efficiency, construction feasibility, and maintenance cost.

[0066] Structural optimization: By optimizing the geometric structure, the system will select the optimal beam-column arrangement and foundation form to ensure the stability and earthquake resistance of the building, while reducing unnecessary material waste and lowering structural costs.

[0067] Material optimization: For different building parts, the system will select appropriate materials according to the building performance requirements (such as thermal insulation, sound insulation, fire protection, etc.). For example, the exterior wall system will give priority to energy-saving and environmentally friendly thermal insulation materials, while the internal partition wall may pay more attention to sound insulation performance.

[0068] Energy efficiency optimization: The system optimizes the energy consumption path by combining factors such as the building's orientation, window ratio, and exterior wall insulation performance. Through simulation analysis, the system will design the best light and heat environment for the building, thereby achieving the goal of reducing energy consumption.

[0069] Implementation 5: Intelligent BIM model generation

[0070] The BIM model optimized through multi-level parameters has a highly intelligent automatic adjustment function. Whenever the design parameters change, the model will automatically update the geometric structure and associated parameters. For example, when the owner requests to change the building height, the system will not only automatically adjust the floor height, but also recalculate the structural bearing capacity and adjust the size of the columns and beams accordingly. At the same time, the intelligent BIM model can also quickly generate multiple design solutions according to different project stages, helping the design team make better decisions when screening solutions.

[0071] The system is operated on a cloud computing platform and supports multi-team collaborative design. For example, different professional design teams such as architects, structural engineers, and mechanical and electrical engineers can access and modify the model at the same time, and all modifications are synchronized in real time, greatly improving the efficiency and accuracy of collaborative work. In addition, the cloud platform also integrates a building regulations library to ensure that the model automatically complies with relevant regulatory requirements during the design process.

[0072] Implementation 6: Model Verification and Simulation

[0073] After the BIM model is generated, the system verifies and validates the model through a variety of simulation technologies. The simulation content includes:

[0074] Structural simulation: The system simulates the load, stress, deformation, etc. of the building structure through finite element analysis to ensure the safety and stability of the building under various load conditions.

[0075] Energy consumption analysis: Through the energy consumption simulation analysis system, the energy consumption performance of the building under different climatic conditions is simulated to find the most energy-saving design solution and ensure that the building meets high energy efficiency standards.

[0076] Environmental adaptability test: The system evaluates the adaptability and comfort of a building in an actual environment through lighting, ventilation and temperature simulation, ensuring the thermal comfort and light environment quality of the building's interior space.

[0077] At the same time, virtual reality (VR) technology is also used at this stage. Through immersive experience, the design team and the owner can intuitively feel the spatial effect and functional layout of the building, and further verify whether the design meets the needs. For example, through VR experience, the owner can experience the internal traffic line design and sense of space of the building in advance, so as to make modification suggestions and ensure that the final design is more in line with their expectations.

[0078] Implementation method seven: Automatic generation of construction plan

[0079] After the model optimization and verification is completed, the system automatically generates a detailed construction plan based on the final optimized BIM model. The construction plan includes:

[0080] Construction drawings: The system automatically generates accurate floor plans, elevations, sections and detailed node drawings based on the model.

[0081] Bill of Quantities: Automatically generate an accurate bill of materials based on the building materials and components involved in the model to facilitate procurement and cost control.

[0082] Construction schedule: The system automatically generates a construction schedule based on the various components of the model, optimizes the construction process, and avoids process conflicts.

[0083] Budget Assessment: Automatically generate budget estimates based on the bill of quantities and current market prices to help owners better control project funds.

[0084] In addition, the BIM model is combined with the digital twin technology of construction machinery, and the system can realize the automation and intelligent control of the construction process. For example, mechanical equipment such as excavators and cranes can automatically complete the corresponding construction operations according to the instructions of the digital twin model, which greatly improves the construction efficiency and accuracy and reduces the errors that may be caused by human operation.

[0085] Implementation 8: System module construction and function description

[0086] The system relies on multiple core modules, including:

[0087] Parametric rule setting module: used to generate association rules between design parameters according to project requirements.

[0088] Model generation module: Generates a preliminary BIM model framework through parametric rules, with highly flexible geometric and functional components.

[0089] Optimization module: Apply multi-objective optimization algorithms to comprehensively optimize parameters at different levels to ensure the optimal combination of materials, structure and energy efficiency.

[0090] Model verification module: Use a variety of simulation technologies to test the performance of the model, including structural simulation, energy consumption analysis and environmental adaptability testing.

[0091] Automatic construction generation module: automatically generates a complete construction plan based on the final model to ensure the accuracy and feasibility of the plan.

[0092] Implementation Method 9: Cloud Collaborative Design and Data Security

[0093] The system uses a cloud-based collaborative design platform to enable experts and design teams from different fields to participate in the design, optimization and adjustment of models in real time. The platform has high concurrent processing capabilities and can support multiple users to operate simultaneously, improving design efficiency. In order to ensure the security of project data, the system introduces blockchain technology to ensure the security and transparency of design data during multi-party transmission and sharing, and prevent data tampering and leakage.

[0094] Implementation Method 10: Data Sharing and Information Transparency

[0095] The application of blockchain technology ensures the data security of project participants. The system will record every design modification and parameter optimization to ensure that all operations in the design process are traceable, and ensure efficient and secure data transmission between different parties through smart contracts. At the same time, the system provides the data information required by all parties to ensure the transparency and consistency of information flow from concept to implementation of architectural design.
