The organisers of the Russian Grand Prix have confirmed that work is on schedule at the Sochi track.

The racetrack is being built within the complex that will host the 2014 Winter Olympics, with the first Formula 1 race in Russia scheduled for the same year.

A statement from Formula Sochi said: "Many massive Olympic venues are already built, some sport facilities have been put in commission, while the motorsport venue is in the active phase of construction.

"Construction crews are making good progress with the preparing of groundworks and laying of the asphalt coat. The first layer of pavement has been laid in some areas."

Circuit designer Hermann Tilke added: "We are deeply involved in the Russian Grand Prix project and we are glad that all works are going according to schedule considering the large amount of coordination necessary with the Olympic construction."

The race control building is said to be near completion, with installation works at the pit complex due to get underway in the spring.
