With the Grand Opening of Barclays Center scheduled for September 28, it looks like things will be a little tight. The latest report by engineering consultants for the arena bondholders is projecting a completion date of September 5, a little more than three weeks before the Jay-Z concert.

The next significant milestone in the construction timetable is installation of the arena scoreboard and video boards which is expected to start March 6 and the installation of ice rink systems starting 10 days later. Metal deck roofing is also expected to be completed the first two weeks of March. Meanwhile, the Empire State Development Corporation, which is working with Forest City Ratner on construction noted, "Yard construction hours have the potential to extend until 3:00 AM Monday through Friday".
