How Is Digital Technology Applied in GRC Curtain Wall Installation? Smart Construction and Qinglong Group's Digital Twin Practice

The application of digital technology in GRC curtain wall installation is upgrading from an "auxiliary tool" to a "core driver". Through BIM collaborative design, 3D laser scanning, UAV aerial surveying, digital twin and other technologies, installation accuracy has achieved a leap from centimeter level to millimeter level. In complex projects such as the 9,000 double-curved panels of the Wuhan Han Show Theatre and the 120,000-square-meter wave-shaped roof of the Hainan International Convention and Exhibition Center, Qinglong Group used digital technology to control installation errors within ±2mm and improve work efficiency by more than 40%. Our digital system consists of four major modules—"cloud-based collaborative design, intelligent layout and positioning, real-time progress monitoring, and digital delivery and O&M"—bringing revolutionary changes to GRC curtain wall installation.

BIM Technology Enables Full-Process Collaboration

Using the Revit+Rhino platform, a digital model of the GRC curtain wall is created for clash detection and installation sequence simulation. In the Shenzhen Yirui Biotechnology Building project, BIM identified and resolved 137 design conflicts, avoiding on-site rework. The model directly exports machining data to drive CNC machine tools in mold production, with surface profile errors ≤0.2mm.

3D Scanning Technology for Precise Positioning

Laser scanners (accuracy ±1mm) capture the building's actual point cloud, which is compared with the design model to generate installation adjustment values. In the double-curved curtain wall of the Nanning New Media Center, scanning revealed substrate deviations of up to 25mm, and the installation plan was optimized through digital pre-assembly. Layout robots automatically mark points, increasing efficiency by 5 times.

UAV and IoT Real-Time Monitoring

Drones conduct weekly aerial photography, with image recognition used to analyze installation progress; sensors monitor the stress at connection joints and automatically issue alerts for anomalies. Qinglong Group's digital twin platform enables virtual-real mapping, providing a data foundation for operation and maintenance. Digital technology has brought GRC installation into the intelligent era.
