Latest Construction Update: noisy overnight work to begin May 14 (updated); Flatbush prepped for green roof work; B3 prep work begins

According to the latest Atlantic Yards/Pacific Park Construction Update, released today by Empire State Development after preparation by Greenland Forest City Partners, some major work is planned this week and next.

Notably, starting Wednesday May 13, there should be be several nights of noisy, disruptive overnight work at the intersection of Atlantic Avenue and Sixth Avenue. In the previous alert, the time needed was estimated at five-six nights. No total is now listed, which suggests it could go longer.

Update: the work will start Thursday, May 14, and last seven nights.

Also, the developers plan work on Flatbush Avenue in preparation for installing a crane to work on the Barclays Center's green roof. That work includes installation of fencing and overhead protection, as well as the removal of the benches, as well as deliveries.

Finally, not only is work expected on the B2 modular tower at Flatbush Avenue and Dean Street, but also site preparation and preliminary excavation/foundation work should begin at the B3 site at the corner of Dean Street and Sixth Avenue.
