Parametric Design Workflow and Key Technologies for Complex GRC Shapes

In contemporary architectural design, freeform shapes have become an important language for expressing architectural individuality and artistic value. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the core value of parametric design in realizing GRC freeform shapes. This article systematically analyzes the parametric design process and key technologies for GRC freeform shapes, providing designers and owners with a full-cycle solution from concept to realization.

The Underlying Logic and Process Framework of Parametric Design for GRC Freeform Shapes

GRC (Glass Fiber Reinforced Concrete), featuring light weight, high strength, and great freedom of shape, has become an ideal material for realizing complex building envelopes. By establishing mathematical models and geometric logic, parametric design transforms designers' creativity into quantifiable, adjustable digital information, greatly improving the design precision and production efficiency of GRC freeform components. Its core process includes: 3D model construction (based on tools such as Rhino and Grasshopper) → performance parameter optimization (such as material mix adjustment for flexural strength ≥20MPa) → segmentation and mold design (taking into account demolding feasibility and convenience of transportation and installation) → digital production integration (achieving seamless connection with CNC machining through BIM technology). In the Dongguan Women and Children's Activity Center project, Qinglong Group used this process to control the deviation of the double-curved GRC curtain wall within ±3mm, winning the Silver Award of the AALBORG WHITE Cup GRC Construction Engineering Innovation Award.

Key Technology 1: Collaborative Optimization of Parametric Modeling and Performance Simulation

The difficulty with freeform shapes lies in balancing aesthetic expression with structural safety. Relying on its provincial engineering technology center, Qinglong Group has developed a parametric design system integrating structural mechanics analysis: custom algorithms embedded in the Grasshopper platform automatically generate component thickness distribution schemes that meet wind load, seismic grade, and other requirements; ANSYS software simulates the effect of different glass fiber contents (typically 4-5%) on the deflection of GRC components, ensuring that boldly shaped cantilevered sections maintain long-term stability. In the Century Plaza renovation project on Nanjing East Road, the parametric design of translucent concrete and GRC composite components adopted this technology, achieving a perfect balance between light transmittance and structural strength, and won the Silver Award of the first UHPC Construction Engineering Innovation Award.

Key Technology 2: Digital Production and Precision Control System

The value of parametric design must ultimately be realized in production. Qinglong's Guangxi production base is equipped with a fully digital production line: 3D laser scanning technology is used for precision re-inspection of molds (error ≤0.5mm/m), and RFID chips enable full life-cycle traceability of components; for complex shapes such as double-curved surfaces and hollowed-out patterns, flexible mold technology has been innovatively developed, achieving a minimum radius of curvature of 300mm. This digital closed loop of “design-production-installation” ensured the one-time installation success of a 5000㎡ GRC freeform curtain wall for a commercial complex in Guangzhou, shortening the construction period by 40% compared with traditional processes.

Qinglong's Full-Chain Services Empowering the Realization of Freeform Shapes

As a national “Specialized, Refined, Distinctive, and Innovative” enterprise, Qinglong Group not only provides technical solutions but also integrates full-chain resources covering detailed design, manufacturing, construction and installation, and after-sales maintenance. To address the shape realization challenges that concern designers, it offers whole-process technical support from scheme optimization to node detail drawings; to solve owners' cost control pain points, it reduces material waste by more than 15% through parametric segmentation optimization. From domestic landmark buildings to overseas projects in Southeast Asia, Qinglong, guided by its mission of “creating beautiful architecture”, has completed a cumulative 600,000㎡ of GRC/GRG/UHPC freeform component projects, becoming a benchmark enterprise in the industry driven by both “technology + service”.

Parametric design is reshaping the boundaries of architectural decoration, while technological breakthroughs in GRC materials provide the material foundation for this innovation. Qinglong Group will continue to deepen the integrated application of digital technology and new building materials, providing reliable support for bringing more designers' creative ideas to life and driving the architectural decoration industry toward greater efficiency and artistry.
