How to Handle Change Requests in GRC Projects

In UHPC/GRC/GRG/GRP engineering projects, change requirements are a key variable affecting project schedule and quality. With 28 years of full-chain experience, Qinglong Group deeply understands the importance of GRC project change management for designers, owners, and contractors. This article provides the industry with systematic response approaches from three aspects: root cause analysis of change requirements, full-process control strategies, and technical solutions.

### I. Core Causes and Risk Boundaries of GRC Project Change Requirements In the field of architectural decoration, change requirements often arise from three major contradictions: the gap between design creativity and engineering implementation, deviations between material performance and environmental adaptation, and the tug-of-war between project schedule and cost control. Take a GRC curtain wall project for a commercial complex as an example: the double-curved geometry of the preliminary design proved unachievable with traditional molds during the detailed design stage, requiring substitution with UHPC material and adjustment of installation joints—if such changes are handled improperly, they may cause schedule delays of more than 30%. Drawing on 28 years of project experience, Qinglong Group has developed a “Change Risk Assessment Matrix” that establishes quantitative standards across three dimensions—technical feasibility, cost fluctuation value, and schedule impact—to provide data support for change decisions.

### II. A Full-Chain GRC Change Control System **1. Detailed Design Stage: Proactive Prevention Mechanism** Before GRC/GRG component production, Qinglong uses BIM technology for parametric modeling to simulate in advance the spatial relationships and structural forces during installation. For example, in a GRG ceiling project for a theater in Nanjing, BIM clash detection identified 12 pipeline conflicts in the original design, and design optimization was completed before production, avoiding material waste caused by later on-site cutting. This “digital rehearsal” reduced the change occurrence rate by 40%, demonstrating Qinglong’s technological innovation advantages as a National High-Tech Enterprise.

**2. Manufacturing Stage: Flexible Capacity Response** Facing ad-hoc changes, Qinglong’s 600,000-square-meter production base can quickly switch mold production lines. Taking UHPC exterior wall panels as an example, modular mold design compresses the modification cycle of a single component from the traditional 7 days to 3 days. Meanwhile, the “Material Performance Database” matches post-change strength and weather resistance requirements in real time, ensuring products comply with the industry standard General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components.

**3. Construction and Installation Stage: Dynamic Adjustment Solutions** On-site changes must balance safety and efficiency. Qinglong’s construction team is equipped with 3D laser scanners; in the GRC cornice adjustment of a landmark project, comparing scan data with the design model achieved millimeter-level precision cutting and joining. In addition, for overseas projects such as change requirements for a GRP daylighting roof at a hotel in Malaysia, Qinglong relies on its overseas offices to provide 24-hour response, ensuring smooth cross-time-zone collaboration.

### III. Technology Empowerment: Change Adaptability Advantages of UHPC/GRC Materials Differences in material properties directly affect the difficulty of handling changes. Compared with traditional stone, GRC material weighs only 1/4 as much, reducing hoisting costs during shape adjustments; UHPC’s ultra-high compressive strength (≥150MPa) provides greater safety redundancy in structural changes. The Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), which Qinglong participated in developing, specifically standardizes the material replacement process in change scenarios, providing a technical reference for the industry.

### IV. Long-Term Assurance: Qinglong’s Full Lifecycle Service System From detailed design consulting at the early project stage to after-sales maintenance later on, Qinglong has built a “closed-loop management of change requirements” mechanism. For example, GRC landscape components supplied for a municipal project required enhanced impact resistance after delivery due to urban planning adjustments; Qinglong completed the modification within 30 days through on-site inspection and a material upgrade plan, reflecting the corporate values of “honesty, perseverance, trust, and collaboration.” For more industry information: +WeChat qlfsbl123

The essence of change requirement management is the ability to coordinate full-chain project resources. Building on 28 years of industry experience, Qinglong Group integrates technological innovation with its service system, turning change risks into opportunities to enhance project value and providing designers and owners with worry-free solutions from concept to implementation. In the field of new architectural decoration materials, choosing a supplier with full-chain capabilities is the key to meeting the challenges of change.
