The venue, though, has already been touched by tragedy, with construction workers Fabio Luis Pereira, 42, and Ronaldo Oliviera dos Santos, 44, having died during an accident in November 2013.
There have also been deaths during work on the Arena da Amazonia in Manaus and the Estadio Nacional Mane Garrincha in Brasilia.
