Innovative Application and Practical Exploration of Digital Technology in GRC Curtain Wall Installation

As building skins become an important carrier of urban aesthetics, GRC curtain walls are using digital technology as their brush to sketch out architectural skylines that combine artistic sensibility with engineering precision. As an industry practitioner with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has consistently driven curtain wall system upgrades through technological innovation, redefining the boundaries of architectural decoration amid the wave of digitalization.

### Digital Technology Reshapes the Entire GRC Curtain Wall Installation Process In traditional GRC curtain wall installation, deviations between design drawings and on-site construction, as well as precision control of complex shapes, have long been industry pain points. The introduction of digital technology has fundamentally changed this situation. Through the full-process application of BIM (Building Information Modeling) technology, parametric modeling of components can be achieved as early as the design development stage, transforming architects' creative ideas into quantifiable digital models. For example, in a landmark project, the double-curved GRC curtain wall used the Rhino and Grasshopper parametric platforms to precisely split 1,200 irregularly shaped components, keeping production errors within ±2mm—achieving 300% higher efficiency than traditional processes.

### Intelligent Construction Technology Empowers Breakthroughs in GRC Installation Precision The integration of digital technology and intelligent manufacturing is reshaping the production and installation logic of GRC curtain walls. The 3D laser scanning technology introduced by Qinglong Group enables millimeter-level precision surveying of construction sites, generating point cloud models that are compared in real time with design models to ensure the absolute accuracy of installation baselines. In the Dongguan Women and Children's Activity Center project, the "digital pre-assembly + modular hoisting" process compressed a traditional 30-day installation period to 15 days, while achieving 99.8% joint conformity, earning the project the Silver Award of the AALBORG WHITE Cup GRC Construction Engineering Innovation Award.

### Full-Chain Digital Management Ensures Project Delivery Quality As a national high-tech enterprise integrating design development, manufacturing, and construction installation, Qinglong Group has built a digital management system covering the entire life cycle of GRC curtain walls. From parametric collaboration on the design side, to the MES intelligent manufacturing execution system on the production side, and further to the BIM+GIS progress management platform on the installation side, a data-driven closed-loop management system has been formed. In the Nanjing East Road Century Plaza renovation project, its translucent concrete GRC curtain wall achieved full-process component traceability through embedded RFID chips. Combined with a cloud-based quality monitoring system, the project achieved a 100% first-pass acceptance rate, winning the Silver Award of the first UHPC Construction Engineering Innovation Award.

### Future Trends of GRC Curtain Walls Driven by Digitalization With the deep integration of building industrialization and intelligentization, GRC curtain wall installation is developing toward the "digital twin". In the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), which Qinglong Group participated in drafting, digital construction technology has been incorporated into the code requirements. In the future, technologies such as AI algorithm-based intelligent layout, drone-assisted installation positioning, and digital twin operation and maintenance will further unlock the application potential of GRC materials in complex building skins, providing designers with broader creative space.

From classical European lines to modern irregular curtain walls, from manual surveying to digital modeling, the evolution of GRC curtain wall installation technology is a microcosm of the construction industry's digital transformation. As a vice president unit of the China GRC Association, Qinglong Group will continue to build on 28 years of technological expertise, using digital innovation to help more buildings realize the mission of "creating aesthetically beautiful architecture", and set a technical benchmark for the industry in the UHPC/GRC/GRG/GRP niche segments.
