I. BIM + Digital Detailed Design
3D modeling, clash detection, and pre‑assembly simulation enable the resolution of over 90% of installation conflicts in advance.
Automatically generates fabrication drawings, material lists, and welding procedures with an accuracy of **±0.1 mm**.
Applications in projects such as Taiyuan Wusu Airport Terminal 3 and the Yuhang Sports Center have resulted in cost savings of over RMB 8 million in rework expenses.
II. Intelligent Manufacturing Production Line
Fully automated cutting, assembly, welding, grinding, painting, and warehousing & logistics.
Welding robot efficiency has tripled, with a first-pass yield of 99.5%.
China 22nd Metallurgical Corporation’s “dark‑factory” achieved the construction of a three‑story, high‑standard building in just 20 days.
III. On-site Intelligent Construction Equipment
3D measurement robots, welding robots, high-altitude installation robots, and intelligent lifting systems.
Shenzhen Bay Super Headquarters Tower C’s “Smart Construction Center” integrates multiple types of robots, enabling a single operator to control several pieces of equipment.
Construction efficiency has increased by 30%–50%, and the accident rate has been reduced by 50%.
IV. Digital Twins and Full-Process Control
Real-time monitoring of structural stress, deformation, temperature, and wind speed to provide early warnings of potential risks.
Data-driven integrated management of quality, schedule, safety, and cost.
Smart construction is the indispensable path for the steel structure industry’s transformation and upgrading; enterprises should accelerate their technological deployment and strengthen their core competitiveness in digitalization and intelligence.
