How to Establish a Whole Life Cycle Quality Management System for GRC Engineering Projects: Key Elements and Practical Paths Explained

Amid the wave of high-quality development in the construction industry, the quality of GRC engineering projects not only affects building safety and aesthetics, but also directly impacts value realization across the project's entire life cycle. As an industry practitioner with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group understands that a full life cycle quality management system is the core guarantee of engineering quality. Drawing on Qinglong's experience across the entire chain of detailed design, manufacturing, construction and installation, and after-sales maintenance, this article analyzes the key elements and implementation paths of quality management for GRC engineering projects.

Full Life Cycle Quality Management of GRC Engineering: From Design Source to Maintenance Closed Loop

Quality management of GRC engineering projects must run through the four stages of design, production, construction, and maintenance, forming an interlocking management closed loop. Based on its technical accumulation as a national high-tech enterprise, Qinglong Group has built a "three-stage quality control model": in the design stage, precise modeling is achieved through BIM technology and parametric design; in the production stage, standardized manufacturing is implemented on intelligent production lines with an annual capacity of 600,000 square meters; in the construction stage, 3D laser scanning positioning technology ensures installation accuracy; and in the maintenance stage, an IoT monitoring system enables full-cycle tracking. This system has been validated in benchmark projects such as the Nanjing East Road Century Plaza renovation project, where the quality pass rate of its translucent concrete components reached 99.8%, far exceeding the industry average.

Four Core Elements: Building a Solid Foundation for GRC Engineering Quality

Material quality is the first line of defense for GRC engineering quality. Qinglong Group uses a self-developed composite formula of alkali-resistant glass fiber and special cement, giving GRC components a flexural strength of over 20MPa and weather resistance that meets the requirements of extreme environments from -40℃ to 70℃. In production, the ISO9001 quality system has been introduced, with 16 inspection procedures achieving full-process control from raw materials to finished products. Key indicators such as chloride ion content and water absorption all outperform the requirements of the Technical Standard for Glass Fiber Reinforced Cement (GRC) Building Applications (JGJ/T423-2018).

Technological innovation is the driving force of quality management. As a participating drafting unit of the industry standard General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components, Qinglong integrates UHPC and GRC composite application technologies into project practice. In the Dongguan Women and Children's Activity Center project, the combined application of double-curved GRC curtain walls and UHPC sunshades met architectural aesthetic requirements while enhancing structural safety. This capability for technological integration gives Qinglong a unique advantage in complex-shaped projects.

Process control determines the final quality of a project. Qinglong has established a "Project Management Cloud Platform" to monitor key links such as production progress, logistics and transportation, and on-site installation in real time. Taking a commercial complex project as an example, the combination of BIM technology and on-site 3D scanning kept GRC component installation errors within ±2mm, greatly reducing rework rates. Meanwhile, an RFID chip traceability system has been introduced, allowing the production batch, quality inspection records, and installation milestones of each component to be queried, creating a traceable quality archive.

Team capability is the core guarantee for system implementation. Qinglong has assembled a professional team of detailed designers, material engineers, and construction supervisors, with senior engineers accounting for 35%. Through a mentoring mechanism and continuous technical training, team members are proficient in advanced tools such as Rhino parametric design and Grasshopper scripting, ensuring a seamless transition from design concept to construction implementation. This professional capability has earned Qinglong repeated recognition in partnerships with leading real estate enterprises such as Poly and China Overseas.

Implementation Path: From Standard Building to Continuous Optimization

Building a GRC full life cycle quality management system must start with standard development. Qinglong has participated in formulating multiple national and industry standards, translating its own practical experience into industry norms. Internally, the company has compiled the GRC Engineering Project Quality Management Manual, detailing quality control points at each stage, such as structural verification standards in the detailed design stage, mold precision requirements in the production stage, and anchoring strength tests in the installation stage, forming a replicable management process.

Digital transformation is key to improving management efficiency. Qinglong has introduced an MES production execution system and a smart construction site platform, enabling real-time collection and analysis of production data and using big data to warn of potential quality risks. For example, in a municipal project, the system detected abnormal curing humidity in a batch of GRC components, and the curing plan was adjusted in time, preventing quality problems caused by insufficient strength. This digital management model has cut quality problem response time by more than 50%.

A continuous improvement mechanism keeps the system vital. Qinglong has established a "quality review" system: after each project is completed, the technical team analyzes quality data and summarizes lessons learned. Through multi-dimensional inputs such as customer feedback collection, third-party testing and evaluation, and internal audits, the quality management process is continuously optimized. This iterative optimization capability has kept Qinglong's first-time acceptance pass rate for GRC projects above 98% for three consecutive years.

As a dedicated practitioner in the GRC industry, Qinglong Group has always upheld its quality commitment of "meticulousness and excellence." From material R&D to project delivery, from technological innovation to standard development, the full life cycle quality management system has become Qinglong's core competitiveness in serving customers. Going forward, Qinglong will continue to leverage its technical strength as a national specialized, refined, distinctive, and innovative enterprise to provide designers and owners with more reliable GRC solutions, supporting high-quality development in the construction industry.
