The team was deeply involved throughout the project, undertaking scheme design, equipment supply, installation and system commissioning for audio‑video, lighting, numerical‑control machinery and various structures of the large‑scale venue. Pre‑erection helped eliminate structural defects, while innovative construction techniques improved assembly accuracy and efficiency. The performance of numerically‑controlled retractable screens was optimized. Active‑standby redundant backup was applied for the whole system. We completed the challenging large‑scale venue construction with high standards, demonstrating solid professional expertise and execution capability.
