Work to upgrade Guernsey's airport runway might not start until January 2011, the Public Services Department minister has said.
The department's proposals, which will cost around £81m, were given the go-ahead by the States but still have to go out to tender.
A report will then go to the States with deputies having the the final say on who gets the contract.
Deputy Bernard Flouquet said it would be a long process.
He said the timetable included the development being passed by the environment department, which is likely to happen in February.
He said: "The tenders should be received by mid-summer and we should be back to the States hopefully by late summer, early autumn.
"Hopefully we'll be on site, carrying out the development, by the latest in January 2011."
