Has Rio condition to host the games?

Rio readies for the Olympics
STADIUMS
Despite the considerable sports infrastructure built for the 2007 Pan-American Games, Rio will have to build from scratch nearly half the stadium capacity it needs and carry out renovations to provide another 24 percent of the minimum required seating. This will require building a wide array of facilities such as an arena for diving and water polo. The Maracana soccer stadium is expected to be up to par by 2016 because it will be upgraded for the 2014 soccer World Cup to be held in Brazil.

TRANSPORTATION
Rio has a limited metro system that does not link the city center and most of its hotels to the outskirts of Barra da Tijuca, where the venues will be concentrated. The city will spend $5 billion on rapid-transit bus lines to cut through traffic between Barra and the beachside neighborhoods of Copacabana and Ipanema. Organizers say athletes should get to events within 25 minutes, though fans may sit through up to an hour of traffic.

SECURITY
Rio is notorious for violent crime in its shantytowns, or "favelas," driven largely by warring drug gangs. While most of the events are far from Rio's slums, some venues, such as the Maracana soccer stadium, are in areas considered to be high risk. Organizers note that despite these concerns, there were no serious security problems during previous events such as the Pan-American Games and the 1992 Earth Summit.

ENVIRONMENT
The government says it will invest $4 billion to clean up the oft-polluted waters used for sailing and other water sports.

ACCOMMODATION
Rio needs to build several complexes including the Olympic Village that will provide some 25,000 of the 48,000 hotel rooms needed for the Games. Even with these facilities, the city still plans to provide a considerable amount of the total accommodation through cruise ships docked in the port areas of Rio.
