MOSCOW, Jan. 15 (Xinhua) -- The fate of Olympic venues in Sochi after the 2014 Winter Games must come in the scrutiny of Russian government, head of the Audit Chamber said Tuesday.
"Sochi Olympics is a unique project but we are worrying about the post-Olympics heritage," Sergei Stepashin told reporters, adding the Audit Chamber was going to address President Vladimir Putin over future of these venues.
"We are concerned with what will happen (with them) after the Olympics are over, who will maintain these venues, what the cost will be and how to make them pay off though partly," he said.
According to the official, no Olympic venue in the world has ever reimbursed the expenses for its construction. He estimated the annual cost of maintaining sporting facilities in Sochi at 60 billion rubles (about 2 billion U.S. dolars), which was "too expensive."
The government plans to convert the Olympic Villiage in Sochi into an all-season resort,he added.
Meanwhile, Stepashin noted corruption has no chances during preparations for the games.
"We inspect (the project) quarterly, so just to steal something there is impossible," he vowed.
According to the chief auditor, the ever-rising costs of preparations to the games has been connected to the construction of extra infrastructure.
"We've built 27 tunnels of a high class with the total length over 60 km," he put an example.
Under the motto of "Hot. Cool. Yours," the Sochi Games which features 98 medal events will open on Feb. 7, 2014 and run until Feb. 23.
