During the visit, the International Olympic Committee panel headed by Jean-Claude Killy met with the Sochi Organizing Committee, and government and regional officials, along with representatives involved in venue construction.
"There aren't any failings, however there is a huge amount of work ahead, it is a massive, colossal project and everyone who is responsible for it has no time to lose," Killy said during a press conference in Sochi.
Killy said he was confident that all the work would be completed on time and that the IOC delegation, which visited Olympic venues, accommodation and local infrastructure, had no concerns.
Russian Deputy Prime Minister Dmitry Kozak said: "We are confident that the sporting facilities and infrastructure... will be completed on time; the majority of venues will be built by 2012."
Sochi won the right to host the Olympics at an IOC session in Guatemala in July 2007 after a close race with South Korea's Pyeongchang and Austria's Salzburg.
Russia has never hosted the Winter Olympics. Moscow hosted the Summer Olympics in 1980, but the event was marred by a U.S.-led boycott involving more than 60 countries.
