Although the Maracana shouldn't give the IOC much of a headache, the Olympic golf course may be reason for concern as construction has yet to begin with three years to go before the sport makes its return to the games after more than 100 years.
The coordination commission is in Rio to meet with local organizers and monitor the progress made at venues and infrastructure sites for the first Olympics in South America. It is its first visit of the year, and it comes just two months after the IOC told local organizers that "time is ticking" and they must attack the project "with all vigor" to guarantee a successful games in 2016.
IOC President Jacques Rogge said last week he doesn't think he will need to publicly warn organizers about delays, but Brazil has been under pressure to show that preparations are on track.
