Brooklyn Nets co-owner Bruce Ratner, developer of the $4.9-billion Atlantic Yards, initially expected to have Barclays Center ready for the 2007 basketball season. But after surviving major obstacles, the arena opened on its latest schedule and budget on Sept. 28. The $1.1-million arena's hard cost is $524 million; its soft cost is $182 million. Site acquisition and sitework cost $153 million. Financing cost $135 million, and a transit connection cost $76 million.
