Since the first Patch in Brooklyn launched in October 2010, we've been documenting the often rapid progress at the Barclays Center site—from the raising of the first vertical steel beams, the installation of stadium seating and the arrival of giant cranes hoisting pieces of roof.

In between, we've covered the discovery of mysterious vials of arsenic, a rally led by workers claiming they had been cheated out of promised jobs by Forest City Ratner and the 24/7 pace of Atlantic Yards construction.
