Building Process

Columns rings and diagonals form together a web that varies over the section of the tower. The columns are all perfectly straight although the lean over to one direction, giving the tower a dynamic twist. They taper from bottom to top, so to further amplify the perspective view up along the tower.
The diagonals are more or less everywhere the same at 800mm. they consist of straight tubes that run between columns fixing the web of nodes into a stiff web. The rings are placed on the inside and their diameter is fixed at 800mm, they are truly round, following the curvature of the facade that runs along the inside.

Prefabrication of steel

The nodes and tubes of the steel web, that give the tower is characterizing profile, are fully prefabricated and delivered by truck to the site from the Prefabrication factory in Shanghai. The elements are first connected by bolts, and only after the tubes all around have been welded together, the bolt connections are being burned off. Only After the first six rings and all the matching columns and tubes are constructed, the columns are lined out and filled with concrete for stability and fire-proofing.
