Analysis of Construction Challenges and Coping Strategies for 'Zaha-Style' GRC Forms

Amid the collision of contemporary architectural aesthetics and engineering technology, "Zaha-style" flowing curves and non-linear forms have become distinctive symbols of landmark buildings with their unconventional visual tension. However, these complex forms, which use GRC (glass fiber reinforced concrete) as the core material, face multiple challenges during construction, from design deepening to installation precision. As an industry participant with 28 years of deep engagement in the UHPC/GRC/GRG/GRP materials field, Qinglong Group draws on hands-on experience from hundreds of complex projects to systematically decode the construction of "Zaha-style" GRC forms—from material properties and process innovation to whole-process control.

I. Compatibility Challenges Between GRC Material Properties and "Zaha-style" Forms

The essence of "Zaha-style" design lies in achieving dynamic spatial rhythm through continuous curved surfaces, double-curved twisting, and other forms, which places extreme demands on the physical properties and molding processes of GRC materials. Traditional GRC components are prone to problems such as uneven fiber distribution and surface cracking when handling extremely small curvature radii (some projects require ≤300mm) or oversized irregular panels. Through its self-developed low-alkali cement-based formulation and basalt fiber composite technology, Qinglong Group has raised the flexural strength of GRC to above 22MPa, while leveraging 3D scanning and parametric design (Rhino+Grasshopper platform) to achieve millimeter-level precision conversion from digital models to physical components. For example, in a cultural center project, for a 12-meter-high double-curved ribbon form, BIM-based pre-assembly simulation kept on-site installation errors within ±2mm, far exceeding industry standards.

II. Systematic Strategies for Addressing Challenges Across the Entire Construction Process

During the design deepening phase, the non-standardized characteristics of "Zaha-style" forms require breaking through the limitations of traditional 2D drawings. Qinglong's technical team adopts a "digital twin" approach, using point cloud scanning for reverse modeling to build a fully informative model covering material parameters, stress distribution, and installation nodes, thereby preemptively avoiding interference issues in curved surface joining. In the production stage, the vacuum infusion molding process has been innovatively introduced, increasing the density of GRC components by 30%, while embedded RFID chips enable full life-cycle traceability from raw material formulation to curing cycles.

On-site installation is the most challenging phase for "Zaha-style" GRC forms. To tackle the difficulty of high-altitude long-span hoisting, Qinglong developed a modular hoisting system that breaks complex forms into standardized units weighing ≤500kg, and, combined with 3D laser positioning technology, achieves precise "building-block" style assembly. In an international airport project, custom adjustable support steel frames and flexible connection nodes effectively mitigated the impact of thermal deformation on surface continuity, ensuring the stability of the double-curved curtain wall under ±40°C conditions.

III. Paths to Technological Breakthrough from an Industry Collaboration Perspective

Realizing "Zaha-style" GRC forms is by no means a solo act of a single enterprise, but rather deep collaboration among designers, manufacturers, and contractors. As a contributing unit of the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), Qinglong has consistently promoted technology sharing across the industry. Its proposed "form complexity—material performance—construction efficiency" triangle balance model has become an evaluation paradigm for complex GRC projects. By integrating 6 major production bases nationwide (with annual capacity exceeding 600,000 square meters) and a professional installation team of over 200 people, Qinglong delivers full-chain services from design deepening to after-sales maintenance, and has provided technical support for landmark projects such as the translucent concrete project at Century Plaza on Nanjing East Road and the Dongguan Women and Children's Activity Center.

From parametric design to intelligent construction, the construction challenges of "Zaha-style" GRC forms are, in essence, a dual test of materials science and engineering management. With 28 years of technical accumulation as its foundation, Qinglong Group continues to explore industrialized pathways for realizing complex forms through material innovation, digital empowerment, and whole-process control. In the future, as UHPC and GRC composite technologies develop, the boundaries between architectural aesthetics and engineering feasibility will be pushed even further, bringing more "impossible" architectural forms to life.
