Full-Process Parametric Design of GRC Special-Shaped Forms: Qinglong BIM Technology Empowers Creative Realization

Parametric design enables freeform GRC to move from concept to reality with precise support at every step, making it a core means for modern architecture to achieve personalized forms. As a National High-Tech Enterprise, Qinglong Group, leveraging 28 years of UHPC/GRC/GRP detailed design experience, deeply integrates Rhino+Grasshopper parametric tools with BIM technology. In projects such as the Shanghai Astronomy Museum and the Century Plaza on Nanjing East Road, it has established an efficient and precise parametric design workflow for freeform GRC shapes.

#Preliminary Data Collection: Laying the Foundation for Design Parametric design is premised on precise basic data support. The Qinglong team uses 3D laser scanning technology to collect on-site environmental data of the project, and combined with the designers' creative concepts, establishes a base model incorporating terrain and structural boundaries. To meet the performance requirements of freeform GRC components, constraints such as material mechanical parameters and production process limitations are input, providing a data basis for subsequent design optimization and ensuring that the design solution is both creative and feasible.

#Model Building and Optimization: Balancing Creativity and Engineering During the model building stage, Qinglong designers use Grasshopper to write algorithms, transforming abstract creative ideas into adjustable parametric models. By adjusting parameters such as curve curvature and component thickness, dynamic optimization of the form is achieved. Meanwhile, taking GRC material properties into account, structural verification is performed on the model. In the over-3-meter UHPC sculpture project at the Shanghai Astronomy Museum, parametric optimization of component cross-sectional dimensions ensured both a smooth form and structural safety requirements.

#Production and Construction Integration: Data-Driven Full Process The core value of parametric design lies in achieving seamless connection between design, production, and construction. Qinglong Group directly imports parametric model data into production equipment, realizing automated production of mold machining and component prefabrication, improving production efficiency and precision. During the construction stage, model data is shared through the BIM collaboration platform to guide on-site installation and positioning. In the Century Plaza project on Nanjing East Road, parametric design enabled the precise installation of super-large components of 12㎡, demonstrating the advantages of a data-driven full process.

Parametric design of freeform GRC breaks the limitations of traditional design, allowing complex creative ideas to be precisely realized. Qinglong Group, with its professional strength in participating in industry standard development, combines parametric design with full-chain services, providing designers and owners with one-stop solutions from concept to completion. Going forward, Qinglong will continue to deepen its expertise in digital design technology, driving freeform GRC to shine in more high-end projects.
