How to Establish a Full Lifecycle Quality Management System for GRC Projects: Key Elements, Implementation Paths and Optimization Strategies

In the field of architectural decoration, the quality of GRC engineering projects not only concerns the safety and aesthetics of buildings, but also directly affects the whole-life-cycle value of a project. As an industry leader with 28 years of full-chain experience in detailed design, manufacturing, construction and installation, and after-sales maintenance of UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the importance of a whole-life-cycle quality management system for GRC engineering projects. This article provides a systematic quality control solution for designers, owners, and industry peers from three aspects: key elements, implementation paths, and optimization strategies.

Whole-Life-Cycle Quality Management for GRC Engineering Projects: The Closed-Loop Logic from Design to Maintenance

As a new building material that is lightweight, high-strength, and flexible in shaping, GRC (Glass Fiber Reinforced Concrete) has been widely used in high-end projects such as grand theaters, commercial complexes, and landmark buildings. Its quality management must cover four core stages—detailed design, manufacturing, construction and installation, and after-sales maintenance—forming a closed-loop system of "prevention-control-improvement". As a national high-tech enterprise, Qinglong Group, drawing on its experience in participating in the formulation of the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), runs the whole-life-cycle concept through every project, ensuring controllable quality from drawings to completion.

Key Elements: Three-Dimensional Synergy of Materials, Technology, and Management

Building a quality management system for GRC engineering projects requires material performance as the foundation, technological innovation as the driving force, and process management as the safeguard. At the material level, Qinglong Group combines high-purity alkali-resistant glass fiber with special cement, optimizing the mix ratio through 58 patented technologies to ensure that GRC components achieve a flexural strength of over 20MPa and weather resistance meeting the requirements of extreme environments from -40℃ to 70℃. At the technology level, BIM parametric design and 3D laser scanning technology are introduced to achieve precise modeling of complex hyperbolic components, with the minimum curvature radius controllable within 300mm. At the management level, a three-tier "design-production-construction" quality inspection mechanism has been established, with every batch of products tested by third parties. For example, in the Dongguan Women and Children's Activity Center project, the installation precision error of Qinglong GRC components was controlled within ±2mm, winning the Silver Award of the AALBORG WHITE Cup GRC Building Engineering Innovation Award.

Implementation Path: Standardized Processes for Full-Chain Quality Control

Qinglong Group breaks down whole-life-cycle quality management into four standardized stages: In the detailed design stage, structural safety verification and joint optimization are carried out in collaboration with design institutes—for example, in the Nanjing East Road Century Plaza renovation project, the joint design of the translucent concrete and GRC composite curtain wall was validated through more than 100 simulation experiments. In the manufacturing stage, automated production lines and an RFID chip traceability system are adopted to achieve full-process data recording from raw materials to finished products. In the construction and installation stage, 3D positioning technology and modular installation techniques are used to ensure the seamless splicing of 5,000㎡ of GRC exterior wall panels in a commercial complex project in Guangzhou. In the after-sales maintenance stage, a 24-hour response mechanism is established and regular durability inspections are conducted on projects—for example, the GRC components of a landmark project in Malaysia showed a performance degradation rate of less than 5% over a 10-year service period.

Optimization Strategies: Data-Driven and Continuously Improving Quality Upgrades

In response to the industry's deepening understanding of GRC materials, Qinglong Group optimizes quality management through three major strategies: first, establishing the industry's first GRC material database, integrating performance data from 1,000+ projects to provide references for similar projects; second, introducing an AI visual inspection system with a surface defect recognition accuracy of 99.2% in the production process; third, jointly building R&D centers with universities to develop UHPC/GRC composite components, improving durability by more than 30%. In addition, to meet the needs of different customers, Qinglong provides cost optimization solutions for real estate developers, technical support for shape realization for designers, and full-cycle quality traceability reports for government projects, delivering "tailored-to-each" customized services.

From material R&D to project delivery, from technological innovation to service upgrades, Qinglong Group builds a whole-life-cycle quality management system for GRC engineering projects with the philosophy of "meticulousness and striving for excellence". As the vice-chairman unit of the China GRC Association, Qinglong will continue to promote the improvement of industry standards, providing safer, more durable, and more aesthetically valuable solutions for the field of architectural decoration, and helping to realize the mission of "creating beautiful architecture".
