It was a long wait but at 6.40 pm the launch of the new Polcevera viaduct deck between piles 8 and 9 began, the first of the three 100 meters long (the others are 50, altogether 19) to rise at altitude to a height of 40 meters. The operation was postponed for almost two days compared to the weekly construction agenda because after the topographical surveys it turned out that the span was too long by a few centimeters and profiling was necessary. Under the lights of the construction site lights, the beam, almost 2000 tons, already complete with the side covers and part of the slab, was raised by the strand jacks placed on the top segments of the two stacks. Lifting speed has been estimated at around 5 meters per hour, except for complications, operations should end at dawn. "The delicate operation - they explain from the commissioner structure - is the first of its kind in the reconstruction site, it will be performed first of all in full and complete respect for safety. The ascent times and the methods will be decided and evaluated during the operation by the employees of the same who, during the night, will decide how to proceed ".
The mayor Marco Bucci, the governor Giovanni Toti and Giuseppe Bono, the managing director of Fincantieri, a company that with Salini Impregilo has formed PerGenova, the company that is rebuilding the viaduct, assisted the start of the operation. With them also Alberto Maestrini, president of Pergenova. (HANDLE).
