Rio de Janeiro, Apr 6 (EFE).- The costly renovation of Maracana stadium, estimated at some $500 million, does not meet the requirements of the 2016 Rio de Janeiro Olympic Games, so that further reconstruction will be necessary, the Brazilian press said.
The new Maracana, expected to be inaugurated late this month, does not meet International Olympic Committee standards in 39 points, including the dimensions of dressing room tunnels and roof strength, according to a document prepared by the organizers of Rio 2016 and reported on the ESPN sports channel.
The IOC requires the roof to be capable of bearing a weight of 120 tons for the fireworks and lighting effects used in Olympic ceremonies, but the Maracana's new canvas roof can only sustain 81 tons.
The tunnels have a width of 5 meters (16 feet), a height of 3.47 meters (11 1/3 feet), and a 10-percent incline, while the IOC demands dimensions of 6 by 6 meters (20 by 20 feet) and a maximum incline of 3 percent.
Maracana was built for the 1950 World Cup and underwent an extensive renovation for the 2007 Panamerican Games, when seating was greatly expanded.
With a view to the next World Cup, an even more complete renovation was undertaken, so that of the original structure, only the facade of the legendary stadium has been preserved.
