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

In the field of contemporary architectural decoration, GRC (Glass Fiber Reinforced Concrete) has become the preferred material for numerous landmark buildings thanks to its lightweight, high-strength, and flexible shaping properties. However, complex GRC engineering projects often face pain points such as difficult design development, hard-to-control production precision, and challenging construction and installation coordination. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands that the in-depth application of BIM technology is the key to solving these challenges. From the full-process perspective of design, production, and construction, this article analyzes how BIM technology empowers GRC engineering projects, showcasing Qinglong's technical strength and innovative practice in the field of new architectural decoration materials.

BIM-Driven GRC Design Development: Precise Connection from Concept to Implementation

Traditional GRC design often relies on 2D drawings, which easily leads to problems such as ambiguous expression of complex shapes and missing node details. Qinglong Group applies BIM technology throughout the entire design process, achieving visual presentation and precise optimization of design schemes through parametric modeling. Taking a hyperbolic GRC curtain wall project for a grand theater as an example, the team used Revit to build a 3D model combined with Grasshopper for parametric driving, converting the designers' creative ideas into quantifiable model data. This not only overcame the limitation of "armchair design" in traditional approaches, but also pre-emptively avoided 12 potential shape conflicts and structural risks. This "BIM + parametric" design model has increased Qinglong's efficiency in the GRC design development stage by 40%, laying a solid foundation for subsequent production and construction.

BIM Empowers GRC Manufacturing: Quality Upgrading under Digital Control

The production precision of GRC components directly affects the final installation results, and the introduction of BIM technology has enabled Qinglong to transform from "experience-based production" to "data-driven production." At its production base in Nanning, Guangxi, Qinglong has connected BIM models with its production management system, automatically synchronizing information such as component dimensions, materials, and process parameters to CNC machining equipment, ensuring that the error of each GRC panel is controlled within ±2mm. Meanwhile, virtual pre-assembly using BIM models allows splicing problems between components to be identified and corrected in advance, raising the production pass rate to over 98%. This full-process digital control capability is one of the core advantages that enable Qinglong, as a national high-tech enterprise, to maintain its industry leadership in GRC material production.

BIM Optimizes GRC Construction and Installation: An Efficiency Revolution through Collaborative Management

Construction and installation of large-scale GRC engineering projects involves multi-disciplinary overlapping operations, making coordination extremely difficult. Qinglong Group innovatively applies BIM technology for construction simulation and schedule management, integrating multi-disciplinary models covering architecture, structure, and MEP through Navisworks software to achieve a visual rehearsal of the construction process. In a GRC exterior wall project for a commercial complex, the team used BIM technology to optimize hoisting sequences and anchoring node design, shortening the on-site installation period by 25%. Meanwhile, through 3D laser scanning positioning technology, precise alignment between GRC components and the main structure was ensured, with installation errors controlled within an industry-leading range of ±5mm. This "BIM + smart construction" model fully demonstrates Qinglong's professional capabilities and technical accumulation in GRC engineering construction and installation.

Qinglong's BIM Practice: Leading Industry Development through Technological Innovation

As a vice-chairman unit of the China GRC Association and a member of the International GRC Association, Qinglong Group has always made technological innovation the core of its development. The company has not only participated in the formulation of multiple industry standards such as the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC), but has also deeply integrated BIM technology with new materials such as UHPC, GRG, and GRP, forming a full-chain solution covering design, production, construction, and maintenance. From large convention and exhibition centers in China to landmark buildings overseas, Qinglong's BIM application cases have spread across the domestic market and Southeast Asia, providing designers with unlimited possibilities for realizing their creativity and creating greater engineering value for owners. Moving forward, Qinglong will continue to adhere to the strategic principle of "focusing on the development of UHPC/GRC/GRG/GRP," using BIM technology as an engine to drive the digital transformation of the new architectural decoration materials industry and fulfill its mission of "creating beautiful architecture."
