La galleria di base del Monte Ceneri è pronta per la posa della tecnica ferroviaria, ovvero dei binari e dei cavi dell'elettricità, oltra a quelli delle telecomunicazioni: il consorzio Condotte-Cossi, che si era aggiudicato i lavori nell'ottobre del 2009 per circa 1,1 miliardi di franchi, ha comunicato oggi (martedì) di aver consegnato l'opera alla committente AlpTransit Gottardo.
Nei tempi previsti, dal gennaio 2010 sono stati scavati due tunnel paralleli di 15 chilometri di lunghezza, estraendo 2 milioni di metri cubi di roccia. sono stati impiegati oltre un milione di metri cubi di calcestruzzo (in particolare per il rivestimento), 9'000 tonnellate di acciaio e 1'600 chilometri di tubazioni.
