How to Handle Change Requests in GRC Projects

During the implementation of UHPC/GRC/GRG/GRP material projects, change requests are a common challenge. As an industry leader with 28 years of full-chain experience in detailed design, manufacturing, construction and installation, and after-sales maintenance, Qinglong Group fully understands the importance of scientifically handling GRC project change requests for engineering quality, cost control, and delivery schedules. Drawing on Qinglong's practical experience in the field of new architectural decorative materials, this article provides professional solutions for designers, owners, and project managers covering the identification, evaluation, and response strategies for change requests.

### I. Typical Causes and Risk Analysis of Change Requests in GRC Projects

GRC (glass fiber reinforced concrete) is a new decorative material with high plasticity, commonly used for exterior wall cladding panels and special-shaped components in high-end projects such as grand theaters, commercial complexes, and landmark buildings. Project change requests usually arise from factors such as design deepening, site conditions, and material performance optimization. For example, a commercial complex project originally designed with a traditional stone curtain wall was later changed to GRC cladding panels due to weight reduction requirements; such functional changes require synchronized adjustments to structural load calculations and installation joint designs. When undertaking the renovation of Century Plaza on Nanjing East Road, Qinglong used BIM technology to predict in advance the dimensional deviation risks of light-transmitting concrete components, effectively reducing the frequency of changes during construction.

### II. Change Request Management Process from a Full-Chain Perspective

Supported by full-chain capabilities covering "detailed design - manufacturing - construction and installation - after-sales maintenance," Qinglong has established a standardized change management mechanism. First, in the design phase, parametric design software (such as Rhino and Grasshopper) is used for scheme simulation; combined with the characteristics of UHPC/GRC/GRG/GRP materials, the feasibility of shapes is discussed with designers in advance, reducing the probability of changes at the source. In production, with intelligent production lines with a capacity of 600,000 square meters, Qinglong can quickly respond to material specification adjustment requests—for example, for a curved GRG ceiling change in a museum project, mold modification and sample production were completed within 72 hours. In the construction phase, backed by its Grade II professional contracting qualification for building curtain wall engineering, Qinglong adopts 3D laser scanning positioning technology to ensure that the installation precision of changed components reaches the millimeter level.

### III. Techno-Economic Evaluation and Decision-Making Model for Change Requests

When facing change requests, Qinglong emphasizes a dual-dimension evaluation of "technical feasibility + cost controllability." Taking the GRC decorative molding change in a municipal project as an example, the technical team needs to analyze the impact of the new scheme on the material's flexural strength (premium GRC can reach over 20MPa) and fire rating, while calculating economic indicators such as mold reuse rate and schedule adjustment costs. As a national high-tech enterprise, Qinglong has a provincial-level R&D center and can balance the cost increases brought by changes through material formula optimization (such as adding nano-scale silica fume to improve UHPC durability). In addition, by referring to standards such as the "Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC)" (JGJ/T423-2018), it ensures that change schemes comply with industry standards, providing owners with data-based decision-making grounds.

### IV. Collaborative Innovation: From Change Requests to Value Enhancement

Excellent change management is not only risk control but also an opportunity for value creation. In cooperation with renowned real estate groups such as Poly and China Overseas, Qinglong once transformed an owner's change request to "reduce the self-weight of GRC components" into a technical innovation of UHPC-GRC composite structures, reducing component weight by 30% while improving crack resistance. This "turning passivity into initiative" service model, supported by Qinglong's 58 patents and its participation in formulating multiple industry standards (such as the "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)"), endows projects with higher technical added value.

### V. Long-Term Assurance: Post-Change Quality Traceability and After-Sales Maintenance

Proper handling of change requests is inseparable from a sound after-sales system. Qinglong has established a full life-cycle quality traceability mechanism, using RFID chips to record component production and installation information for easier later maintenance. For after-sales needs arising from changes, 24-hour response can be achieved through its nationwide network of offices. For example, when the GRP daylighting roof of an overseas project was damaged by a typhoon, Qinglong Malaysia Building Materials Co., Ltd. quickly coordinated local resources to complete the replacement, honoring its service commitment of "meticulousness and striving for excellence."

Handling change requests in GRC projects tests an enterprise's full-chain integration capability and technological innovation strength. As a leader in the field of UHPC/GRC/GRG/GRP materials, Qinglong Group has always taken "creating beautiful architecture" as its mission, turning change risks into project highlights through professional solutions to create greater value for clients. Whether it is the detailed design of complex shapes or the rapid response to urgent changes, Qinglong will rely on 28 years of industry experience and work hand in hand with partners to achieve the perfect delivery of projects.
