The difference between the Jaypee Group Circuit and the Commonwealth Games is that the circuit is being built exclusively by private contractors. The government in New Delhi has been bankrolling the Commonwealth Games site, but the Indian Grand Prix circuit will be done through private construction firms. It will also be overseen by Hermann Tilke – one of the reasons why Tilke gets all the circuit design commissions is because Tilke GmbH is not simply an architecture firm: they offer construction services as well. Tilke has overseen the construction of every circuit since Sepang with the exception of the Korean International Circuit.
F1 is different, yes they are having trouble but they very determine in getting their sports going on in the right time. Like they did with cricket so I hope they have a trouble free time & organize a good race.
