What Factors Should Be Considered in the Lifting Plan of Super-Large GRC Shapes?

In the field of modern architectural decoration, GRC materials, with their lightweight, high-strength properties and flexible shaping capabilities, are widely used in complex shapes for large landmark buildings, commercial complexes, and other projects. As a critical construction procedure, the hoisting of super-large GRC shapes directly affects the overall quality and progress of a project in terms of the scientific soundness and safety of its plan. As an industry leader with 28 years of experience in detailed design, manufacturing, construction, and installation of UHPC/GRC/GRG/GRP materials, Qinglong Group draws on practical experience from hundreds of large projects to provide an in-depth analysis of the core factors that must be considered in hoisting plans for super-large GRC shapes.

### I. Analysis of GRC Component Characteristics and Hoisting Parameter Compatibility Super-large GRC shapes typically feature complex irregular structures, heavy unit weight (up to several tons), and high installation precision requirements, so the physical parameters of the components must first be clarified. Key checks should focus on the dead weight distribution, center of gravity position, flexural strength (high-quality GRC can exceed 20MPa), and surface flatness of GRC components, ensuring that hoisting point placement matches the load-bearing characteristics of the components. For example, for double-curved GRC curtain wall panels, BIM technology should be used to simulate stress changes during the hoisting process to prevent component cracking caused by excessive localized stress. During the detailed design phase, Qinglong Group employs 3D scanning and parametric modeling technologies to optimize component structures in advance, providing precise data support for hoisting plans.

### II. Hoisting Equipment Selection and Site Environment Compatibility The selection of hoisting equipment requires comprehensive consideration of factors such as GRC component weight, installation height, and on-site space conditions. For super-large GRC shapes exceeding 50 meters in height, large-tonnage truck cranes or crawler cranes are typically required, with verification of the compatibility among boom length, working radius, and rated lifting capacity. Meanwhile, site foundation bearing capacity, surrounding obstacles (such as high-voltage power lines and existing buildings), and weather conditions (wind speed, temperature) are also key variables. For example, in typhoon-prone areas, contingency plans for suspending hoisting operations when wind speeds exceed 10m/s must be established. Qinglong Group's construction team works with third-party institutions to conduct site surveys and equipment selection verification, ensuring that the hoisting process is safe and controllable.

### III. Hoisting Techniques and Installation Precision Control The hoisting techniques used for super-large GRC shapes directly affect installation precision and overall aesthetics. Modular hoisting technology should be adopted, using prefabricated connectors and 3D positioning systems to achieve precise component alignment with tolerances controlled within ±3mm. For special shapes such as openwork and cantilevered designs, temporary support systems are also required to prevent component deformation during hoisting. Qinglong Group's proprietary "BIM + 3D laser scanning" installation technology enables real-time monitoring of hoisting deviations and dynamic adjustments, and has been successfully applied to complex projects such as the Nanjing East Road Century Plaza renovation project, ensuring "mirror-grade" joining between GRC components and glass curtain walls.

### IV. Safety Protection and Emergency Plan Development Safety is the core prerequisite for super-large GRC hoisting. Load-bearing capacity verification and non-destructive testing must be performed on hoisting rigging (such as wire ropes and shackles), and fall-prevention devices and warning zones must be set up. At the same time, comprehensive emergency plans should be developed, covering response procedures for unexpected situations such as component falls and equipment failures. As a National High-Tech Enterprise, Qinglong Group has established a strict safety management system: all hoisting operators hold special operation qualifications, and every project is staffed with a dedicated safety engineer providing full-process supervision.

### V. Full-Chain Coordination and Quality Traceability The hoisting of super-large GRC shapes is not an independent procedure; it must seamlessly integrate with detailed design, manufacturing, on-site installation, and other phases. Relying on its full-chain service advantages spanning "design-production-construction-maintenance", Qinglong Group organizes joint reviews of hoisting plans by the design, engineering, and production teams at the initial project stage, ensuring consistency from material selection to final installation. In addition, RFID chip implantation technology enables quality traceability across the entire component lifecycle, providing data support for later maintenance.
