Application and Practical Research of Digital Technology in GRC Curtain Wall Installation

Digital Empowerment of GRC Curtain Wall Installation: A 28-Year Practice Journey from Precision Revolution to Efficiency Leap

In the field of architectural decoration, GRC (glass fiber reinforced concrete) has become an ideal choice for the curtain walls of high-end buildings such as grand theaters and commercial complexes, thanks to its lightweight yet high-strength properties and design freedom. However, traditional GRC curtain wall installation often faces pain points such as the disconnect between detailed design and on-site construction, insufficient component precision, and low installation efficiency. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has always upheld the mission of "creating beautiful architecture," deeply integrating digital technology into the entire GRC curtain wall installation process. Through BIM technology, parametric design, intelligent production, and construction coordination, it has redefined the standards of precision and efficiency in GRC curtain wall installation, providing designers and owners with a full-chain, expert-level solution from detailed design to after-sales maintenance.

I. Digitally-Driven Detailed Design of GRC Curtain Walls: Precise Transformation from Drawings to Models

In GRC curtain wall projects, detailed design is the core stage that determines the final appearance. Relying on the technical expertise accumulated at its national-level R&D center, Qinglong Group deeply integrates BIM (Building Information Modeling) technology with parametric design tools (such as Rhino+Grasshopper), achieving a seamless transformation from 2D drawings to 3D models. Taking a landmark convention and exhibition center project as an example, its facade features a double-curved GRC curtain wall whose complex curved surface relationships were difficult to express precisely with traditional 2D design. Qinglong's technical team established fully parametric GRC component models, translating architectural aesthetic requirements into quantifiable geometric parameters. Combined with on-site 3D laser scanning data, they proactively avoided structural errors and installation conflicts, improving detailed design efficiency by 40% and controlling component fabrication precision within ±2mm, laying a solid foundation for subsequent installation.

II. Intelligent Production and Digital Twins: "Millimeter-Level" Smart Manufacturing of GRC Components

As a custom GRC product manufacturer, Qinglong Group has introduced digital production lines at its production base in Nanning, Guangxi, achieving intelligent end-to-end control of GRC components from mold design to finished product delivery. Through digital twin technology, BIM models are linked in real time with production equipment, automatically generating component fabrication instructions to ensure consistency between mold precision and component dimensions. Meanwhile, RFID chip implantation technology gives each GRC curtain wall panel a "digital ID card" recording key information such as material mix ratios, production time, and quality inspection results, enabling full lifecycle traceability. This digital production model has not only raised the component pass rate to 99.5% but also shortened the production cycle by 30%, meeting large-scale projects' demand for GRC materials with "mass production and fast delivery."

III. Digital Collaboration in Construction and Installation: From "On-Site Adaptation" to "Precision Assembly"

Traditional GRC curtain wall installation relies on manual on-site layout and adjustment, is easily affected by environmental factors, and often results in large installation errors and schedule delays. Qinglong Group innovatively adopts "3D positioning + modular installation" technology, comparing BIM models with on-site measurement data in real time and using total stations and drone surveying to establish construction coordinate systems, keeping GRC curtain wall panel installation errors within ±3mm. In a commercial complex project, the Qinglong team used digital pre-assembly technology to simulate the installation process in a virtual environment in advance, optimizing lifting sequences and joint treatment solutions. This raised on-site installation efficiency by 50%, reduced high-altitude work time, and significantly lowered construction risks.

IV. Full-Chain Digital Services: The Core Advantages of Qinglong's GRC Curtain Wall Solutions

From detailed design to after-sales maintenance, Qinglong Group uses digital technology as a link to build an integrated "design-production-construction-maintenance" service system. As a vice chairman unit of the China GRC Association, Qinglong participated in formulating the Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018). Its digital practice achievements have been widely applied in real estate, municipal engineering, airports, and other fields. For example, in a high-end residential project developed in partnership with a well-known real estate group, GRC curtain wall digital installation technology enabled "zero-error" delivery of the building facade, earning high recognition from clients. In addition, Qinglong has established an IoT-based after-sales maintenance platform that uses sensors to monitor the structural health of GRC curtain walls in real time, providing owners with proactive maintenance services and extending the service life of buildings.

Digital technology is reshaping industry standards for GRC curtain wall installation. With 28 years of full-chain experience and the R&D strength of a national-level high-tech enterprise, Qinglong Group is guided by its values of "integrity, perseverance, trust, and collaboration," driving the evolution of GRC materials from "traditional decorative components" to "digital building skins." Going forward, Qinglong will continue to focus on the innovative development of UHPC/GRC/GRG/GRP materials, using digital empowerment to create more aesthetically valuable, more efficient, and safer architectural decoration solutions for designers and owners worldwide, steadily advancing toward its vision of "becoming an outstanding world-leading UHPC/GRC/GRG/GRP manufacturing enterprise."
