Leveraging the integrated technology of BIM (Building Information Modeling) and GIS (Geographic Information System), full digital modeling for steel structure design is realized. The design team can visually present building structure details, spatial layout, and pipeline routing through 3D models, and accurately calculate the impact of wind loads, snow loads, seismic loads, etc., on the structure. Meanwhile, AI algorithms are used to automatically optimize component selection and connection methods, avoiding potential issues such as design deviations and pipeline conflicts in advance. Compared with traditional 2D design, digital design improves efficiency by over 60% and reduces design error rates by 90%, providing precise data support for subsequent production and construction phases.

BIM design data is directly imported into the intelligent production system to achieve seamless data connection between design and production. The factory is equipped with automated production lines including CNC cutting robots, automatic welding robotic arms, and intelligent flaw detection equipment, with each process of component processing precisely controlled by digital instructions. The machining accuracy error of components can be controlled within ±0.3mm, and the weld flaw detection qualification rate reaches 99.9%. In addition, digital twin technology is introduced to map the production process in real time, enabling real-time monitoring and traceability of production progress and quality data. Digital production ensures more stable quality of steel structure components and improves production efficiency by more than 5 times compared with traditional modes.

A digital construction mode featuring digital twins + intelligent equipment is adopted. The entire construction process is simulated through BIM models to formulate optimal hoisting paths and construction plans. On-site, intelligent hoisting robots, UAV inspection equipment, real-time monitoring sensors, etc., are deployed to realize automated hoisting processes, visualized construction quality, and intelligent safety risk early warning. For example, intelligent hoisting robots can accurately adjust hoisting angles and forces according to digital instructions, improving installation accuracy by 30%. Real-time monitoring sensors can collect data such as component stress and structural deformation in real time, with automatic early warning for abnormal conditions, greatly reducing construction safety risks.
