How to Establish a Full Life-Cycle Quality Management System for GRC Engineering Projects: Key Elements, Implementation Path, and Optimization Strategies

Quality is the lifeline of GRC engineering projects, and it serves as a dual guarantee for both architectural artistry and structural safety. Today, as UHPC/GRC/GRG/GRP materials are increasingly widely applied, establishing a full life-cycle quality management system has become the core competitiveness of high-end building materials enterprises. As the Qinglong Group with 28 years of deep industry experience, we leverage the technical expertise of a national-level high-tech enterprise to build a closed-loop quality control system covering the entire process of GRC engineering projects—from detailed design to after-sales maintenance—providing designers and owners with worry-free solutions from concept to completion.

1. Core Elements of GRC Full Life-Cycle Quality Management: A Systematic Construction from Materials to Services

Quality control of GRC engineering projects must span five key stages: "material properties - detailed design - manufacturing - construction and installation - maintenance and monitoring." On the material side, Qinglong Group strictly controls the glass fiber content (≥4.5%) and the mix ratio of cement-based materials, ensuring that GRC components achieve a flexural strength of over 20 MPa, while verifying material stability through dynamic elastic modulus testing (≥15 GPa). The design phase integrates BIM technology with parametric design, using Rhino and Grasshopper software to achieve precise modeling of complex double-curved components and keep design deviations within ±2 mm. In production, an automated spray-up forming process combined with 3D scanning inspection technology ensures consistency in dimensional accuracy and surface texture across every batch of components.

2. Implementation Path: Qinglong's Practice in Full-Chain Quality Control

As a vice-chairman unit that participated in drafting the Technical Standard for Application of Glass Fiber Reinforced Cement (GRC) in Buildings (JGJ/T423-2018), Qinglong Group has established a "three inspections and three verifications" quality control mechanism. During the detailed design phase, a team of engineers with over 20 years of experience conducts structural safety reviews, focusing on anchor systems and load transfer paths. During production, a three-level inspection system is implemented—team self-inspection, workshop patrol inspection, and dedicated pre-delivery inspection—with RFID chip traceability for key processes. Before construction and installation, 3D laser scanning positioning ensures on-site deviations of ≤3 mm, and after installation, ultrasonic testing verifies anchor strength. This system has been validated in projects that won the UHPC Innovation Award, such as the translucent concrete project at Century Plaza on Nanjing East Road, achieving the industry benchmark of "zero accidents and zero rework."

3. Optimization Strategies: Technological Innovation Driving Quality Upgrades

Facing challenges in free-form shapes, durability, and cost control in GRC engineering, Qinglong Group continuously optimizes quality management through three major innovation strategies: first, introducing UHPC and GRC composite technology, using ultra-high performance concrete reinforcement at key load-bearing areas to extend component service life to over 50 years; second, developing a modular production system that breaks down complex components into standard and customized modules, reducing production deviations while preserving design freedom; third, establishing a digital maintenance platform that monitors component stress changes in real time via embedded sensors and predicts maintenance cycles with AI algorithms. This "prevention-first, dynamic monitoring" management model enabled Qinglong GRG ceilings to achieve a ten-year zero-maintenance record in a major theater project in Guangzhou.

From the GRC curtain wall of the Dongguan Women and Children's Activity Center to GRP free-form components for overseas landmark projects, Qinglong Group has always honored its quality commitment with a "meticulous and excellence-pursuing" attitude. As a national "Specialized, Refined, Distinctive, and Innovative" enterprise, we understand that quality management of GRC engineering projects is not only a technical matter but also a responsibility for architectural safety and artistic value. Going forward, Qinglong will continue to integrate its 28 years of full-chain experience, driven by technological innovation, to provide designers with more reliable material solutions for realizing their creative visions and to inject new momentum into the high-quality development of the construction industry.
