From the latest Atlantic Yards/Pacific Park Construction Update: street closings Aug. 29 for crane installation at B11 site

The latest Atlantic Yards/Pacific Park Brooklyn Construction Update, covering the two weeks beginning Monday August 17 and delivered at 9:29 am by Empire State Development after preparation by Greenland Forest City Partners, reveals that on Saturday, August 29, a crane installation for the B11 site will require street closings.

Specifically, Dean Street between Vanderbilt and Carlton avenues and one lane of Vanderbilt Avenue will be closed. A community notice with details regarding the crane assembly will be distributed.

Also note that exterior façade adjustments and paint repairs are expected to begin on the B2 modular tower that was supposed to have units delivered complete.

Saturday work will continue at the B3 site at the southeast corner of the arena block. Saturday work as well as work up until 9 pm during weekdays will continue at the B14 site at 535 Carlton Avenue, at Dean Street.

There's new work going on at the B15 site east of Sixth Avenue between Dean and Pacific streets: "preliminary environmental sampling"--both drilling and/or hand excavation--will begin in the basements and open lots on the site. The broadcast lot at the site will be shared/ utilized by both the arena and the B3 site for temporary storage of equipment.

New--or at least purportedly new--information is noted with an asterisk in the text below, and with an asterisk and red type in the document embedded below. I say purportedly new, because some of the information marked as new is not actually new.
