With only the final scaffolding remaining on the Shanghai Tower’s crown and the upper most beam in place, we can now fully visualize the building’s complete silhouette. As visually stunning as the curved tower is, the special features hiding within the silhouette, especially in the tower’s crown, are just as exciting. The tops of most buildings only feature observation zones for tourists, while masking the less interesting but mandatory mechanical elements with opaque glazing. The Shanghai Tower’s crown will of course encourage visitors to enjoy the unparalleled views of Shanghai, but it will also direct gazes towards the inner workings of the building itself and provide glimpses of wind turbines, a rain water collection system and two types of dampening systems: a Tuned Mass Damper (TMD) with Eddy current damping applied. These last two are both near completion.
