F1 - Work racing ahead at 2012 US GP site

450 workers are pushing to enable Austin’s new Circuit of the Americas to be ready for the US grand prix later this year.

After the Texas project’s earlier hiccups, the rooves and walls of the paddock and medical buildings, media centre and main grandstand are now taking shape.

Another recent setback, however, was 2 inches of rain in the last ten days.

"We’ve got a lot of dry weather we know is going to be coming, and are hoping to be gaining some time," said a contractor spokesman.

He revealed that the first layer of track asphalt will be poured around April "so we can get other elements, the tire barriers (and) the FIA fence going on", he told the local Austin American Statesman.

The report said construction is scheduled to be essentially completed two months before the November 18 race.
