(BEIJING, Sept. 17) -- The twig-like structural elements and the bowl-shaped roof are the masterpiece of the National Stadium, the main venue for the XXIX Olympiad where the Opening and Closing Ceremonies will be held. However, they pose great challenges for technicians and workers to remove the supporting frameworks for the venue's steel skeleton.

The over-all uninstalling procedure is scheduled to start at 8:30 am and end at 12:30 am, on Sept. 17, 2006. When 78 supporting structures are took away step by step, the steel skeleton of the National Stadium will be able to stand on its own feet stead of being supported by outside force.
