Steel in the Air - We are not only talking about it now, at last we have something to show too

The lifting of the roof structure of SkyCourt to its place has begun. The fourteen trusses weighing 75 tons each are delivered to the site one by one in 3 pieces. The trusses are assembled on site and hoisted to their dedicated positions in the roof structure. 6 pieces have arrived so far and 5 have already been joined together by the experts of KÉSZ.  Last Friday the first so-called starter unit was positioned on the landside during daytime and the first main truss was lifted to its final position during the night.

While the components of the roof structure are being welded together on site, a mobile crane with load-bearing capacity of 500 tons has started the hoisting of assembled components. This unique crane is capable of hoisting items to a distance of 100 meters and it needs to span 80 meters for the construction of the SkyCourt.
The main trusses are jointed to receiving units of nearly 300 kilograms each, cemented into the roof structure, which channel pressure through the columns down to the foundation. There are two 8-ton V-shaped units to support the main truss at the airside end. The shell-shaped profile of the SkyCourt is defined by the starter unit connected to the façade. The characteristic overhanging “nose” section at the airside will be hoisted into place at the end of each main truss at a later date, as part of the works on the façade.
A truss may be hoisted into place every three days. This is how long it takes to weld the truss to the ancillary units. The first piece is held in position by a crane for these three days as long as the second piece is lifted next to it and welded together with it. While one element is hoisted to its place, the next one is prepared for the same operation.
