Research and Practice on Whole-Process Application of BIM Technology in GRC Engineering Projects

As the digital wave sweeps through the construction industry today, BIM technology is reshaping the full-process management of GRC (Glass Fiber Reinforced Concrete) projects with its visual, collaborative, and intelligent characteristics. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has consistently driven industrial upgrading through technological innovation, deeply integrating BIM technology into the entire chain of GRC project design, production, and construction, providing designers and owners with full-cycle solutions from concept to completion.

**Deep Integration of BIM and GRC: The Technical Key to Solving Industry Pain Points**

GRC materials, with their advantages of light weight, high strength, and flexible shaping, are widely used in high-end settings such as grand theaters, commercial complexes, and landmark buildings. However, traditional project management often faces problems such as disconnect between design and construction, insufficient component precision, and low on-site installation efficiency. The introduction of BIM technology, through three-dimensional modeling and data integration, has enabled GRC projects to leap from "paper designs" to "digital twins". Relying on the technical reserves of its national-level R&D center, Qinglong Group combines BIM models with the detailed design of GRC components, accurately simulating the mechanical performance of complex curved surfaces and irregular structures and avoiding construction conflicts in advance, enabling award-winning projects such as the Dongguan Women and Children's Activity Center to deliver double-curved GRC curtain walls with millimeter-level precision.

**Full-Process Application Practice: From Design Optimization to Intelligent Construction**

In the design phase, Qinglong uses BIM technology to achieve multi-discipline collaborative design, integrating architectural, structural, and MEP models to avoid the information silos of traditional 2D drawings. Taking the Nanjing East Road Century Plaza renovation project as an example, the team used BIM for the parametric design of translucent GRC components, dynamically adjusting shapes and light transmittance through the Grasshopper plugin, which both meets architectural aesthetic requirements and ensures structural safety. In the production stage, BIM models are directly connected to CNC machining equipment, enabling automated mold opening and precise prefabrication of GRC components, increasing production efficiency by more than 30%, while RFID chip implantation enables full lifecycle traceability of components.

During the construction and installation phase, Qinglong adopts BIM + 3D laser scanning technology to compare site conditions with design models in real time, achieving "pre-assembly" and "zero-error" installation. For example, in a large exhibition center project, BIM simulation of hoisting paths and node connection methods compressed the traditional 7-day installation period to 4 days, significantly reducing construction costs. In addition, BIM models provide data support for later maintenance: owners can access the models via mobile devices to quickly locate component information and maintenance records, achieving intelligent operation and maintenance management.

**Qinglong's 28 Years of Expertise: Building a Digital Benchmark for GRC Projects**

As a participating drafter of the "Technical Standard for Application of Glass Fiber Reinforced Cement (GRC) in Buildings", Qinglong Group deeply integrates BIM technology with its full-chain service capabilities, forming an integrated "design-production-construction-maintenance" solution. The company has an intelligent production base with an annual GRC capacity of 600,000 square meters, and combined with BIM technology, it can achieve parallel management of multiple projects, having provided high-quality GRC products for renowned real estate groups such as Poly and Vanke as well as overseas projects. In the future, Qinglong will continue to explore the integrated application of BIM with AI and the Internet of Things, promoting the digital and green transformation of the GRC industry, and, with the mission of "creating beautiful architecture", helping more landmark projects turn creative blueprints into reality.
