Also, there are support arms and spheres installed on the two bridges as it welded in with all the components. Those sky bridges should be using reinforced glass to enable visitors to view outside of the building as well as provide protection from strong wind as the taller the building the stronger the wind will be.
However, at this stage, the basic structure is to show how it might look but may subject to change when required. It also has a shelter on both sky bridges to limit the amount of natural sunlight reach into the interior as possible.
