3.2. Transfer to thePower Station e final re-assembly The transfer to the Power Station was made through a van (Figure 5a), which required the complete disassemble of the three parts of the sculpture. All the batons have been numbered, in order to help the successive re-assembled of the truss system. The re-assemble of the sculpture had to be made in the yard next to the Power Station, both for safety reasons, and for the impossibility to go through the doors with the sculptures. Therefore, a cover has been made next to the building, in order to hold the re-assembling activities (Figure 5 b,c). The fina l re-assembly was made by gluing a ll the batons according to the initia l position. After the “structure” re -assembling, the wood sheets have been put (see Figure 6), to create the externa l skin of the sculpture. The wood sheets have been fixed to the structure through na ils and finished with waterproof pa ints. The fina l step of the work should be the fixing of the sculpture to the building façade. This step, however, was never achieved, as explained in the Section4.

The ma in choice was between a light and a firm connection. Indeed, a very light connection, for instance made of
