What Are the Construction Challenges of "Zaha-Style" GRC Forms? — Qinglong Group's Complex Curved Surface Construction Solutions

"Zaha-style" GRC shapes feature streamlined double-curved surfaces, with construction challenges concentrated in three areas: shape realization, installation precision, and structural safety. Qinglong Group successfully overcame these challenges through digital technology and process innovation.

Shape realization is the primary challenge. Complex curved surfaces must be fabricated in segments, and joint treatment demands high precision. Qinglong Group adopted 3D laser setting-out to break down the overall model into producible units. In the Guangxi New Media Center project, none of the 2,000 panels were identical; through pre-assembly based on the BIM model, joint errors were controlled within 3mm. Total station surveying was used for curved surface positioning, ensuring the overall shape remained fluid.

Installation precision control is highly difficult. Traditional measurement methods could not meet the requirements, so Qinglong Group developed an AR-assisted installation system. Installers view the virtual model through smart glasses and correct positions in real time. This technology raised installation precision to ±2mm and improved work efficiency by 40%.

Structural safety requires special attention. Double-curved panels bear complex loads, and Qinglong Group optimized the hanging point layout through finite element analysis. Carbon fiber reinforcement was added at cantilevered sections to ensure safety under wind vibration. These measures make Zaha-style shapes both beautiful and safe.
