Great uncertainties hang over the ambitious plans submitted to FIFA and the International Olympic Committee.
The 2016 Olympic Games will be the first held in South America, and Rio de Janeiro, the host city, will need around $17 billion in public and private funds to stage it, according to official and independent estimates.
Forty percent of that sum will have to be invested in transport, to resolve Rio's chaotic road system and languishing rail network, and to boost the bus fleet and metro system.
Security is also a priority to tame endemic violence. Urban reorganization will have to take place. The number of hotel rooms need to be doubled.
