MAIN STRUCTURAL CHARACTERISTICS The building is a square with 44 m sides and with a height of 38 m. It consists of a main metal structural frame consisting of 4 large porticoes separated from each other by 14.5 m, and from which the floor structures of the building hang, leaving the ground level of the building, entry level, free of any structural features. Each portico consists of two large pairs of rigid supports at both ends with the remaining span covered with a truss equivalent to two storeys in height. LIFTING PROCESS The construction system consisted of lifting the set of main truss structures, comprising four trusses, the roof and the two floor structures immediately underneath, by means of hydraulic jacks. Points of interest: The total weight of the structure to be lifted was 672 t. The total height covered by this process was 30 m. Lift speed: 1.5 m/hour 8 hydraulic jacks were positioned, one for each rigid support. Each hydraulic jack pulled a 20 mm diameter steel cable, supporting a maximum load of 120 t.
