Now there are three cranes: Atlantic Avenue crane for arena's green roof installed, almost three months late

On Saturday, a large crane (right) was installed along Atlantic Avenue outside the Barclays Center to allow for the installation of the planned green roof.

It joins the large crane at the B3 site, at the southeast corner of the arena block, which was installed two weeks earlier, along with the huge crane outside the stall B2 modular tower.

Left unmentioned by the developers of Atlantic Yards/Pacific Park is that both cranes for the green roof installation were supposed to be installed in August, as shown in the Project Timeline below, from this presentation.

The Atlantic Avenue crane was supposed to be removed by the end of October, after three months--and, presumably, before the Brooklyn Nets season began.

So it looks like the green roof installation process is three months delayed. We should know more at the next Atlantic Yards Quality of Life meeting, set for November 12.

It's not clear how the delays will affect the planned June 2015 start for the B3 tower.
