How to Precisely Position Embedded Parts on Double-Curved GRC Panels?

As the core material for irregular facades of high-end public buildings, double-curved GRC panels require installation precision that directly determines the smoothness of the building's curved surfaces and the overall visual effect. The positioning accuracy of embedded parts is a core control point in the installation of double-curved GRC panels — even a millimeter-level deviation may render an entire batch of custom components impossible to assemble, and may even cause safety hazards such as components falling from height. Qinglong GRC, a manufacturer with 28 years of deep expertise in the GRC field, drawing on implementation experience from over a hundred landmark projects, has developed a full-process control solution for the precise positioning of embedded parts for double-curved GRC panels.

Traditional positioning of embedded parts for double-curved GRC relies mostly on manual setting-out, which is not only inefficient but also easily affected by factors such as datum plane errors at the construction site and on-site deformation. The final positioning deviation often exceeds 5mm, making it difficult to meet the high-precision installation requirements of double-curved components. To address this pain point, the Qinglong team adopted a dual positioning system combining 3D laser scanning + BIM model rehearsal: first, a full-area scan of the keel substrate at the construction site is carried out, and the actual site data is imported into the BIM model to identify issues such as substrate deformation and point conflicts in advance; then the installation coordinates of the double-curved GRC panels are reversely matched to the preset positions of the embedded parts, eliminating at the source the common problem of "positioning per the drawings but failing to fit."

During positioning implementation, Qinglong adopts a "double verification" mechanism to ensure accuracy: first, the coordinate points exported from the model are projected onto the working surface using a high-precision total station, and the initial installation positions of the embedded parts are marked; then the initial positions are verified a second time with 3D scanning equipment, and fixing and grouting proceed only after confirming that the point deviation is controlled within 0.5mm. At the same time, each embedded part is marked with a unique code corresponding to its component, bound to the RFID chip information from the component production stage, achieving full-chain traceability throughout the installation process. This positioning solution has been implemented in multiple large convention and exhibition centers and landmark commercial projects, achieving a 100% installation fitting rate for double-curved GRC panels and greatly shortening the on-site construction period.
