From the latest Construction Update: potentially disruptive railyard work continues (document's a week late)
That seems only slightly late to alert people to construction work, but, actually, they missed a week. The previous two-week Update was issued for April 23. Why were they so sloppy? I don't know; my query about the delay hasn't yet gotten an answer. But there's no new vertical construction or much, if any, new infrastructure work.
Some of what was predicted in the previous Update regarding potentially disruptive work at the Vanderbilt Yard continues, though it appears in red in the document below, which indicates new work, though it's not.
Much concern was raised about Long Island Rail Road (LIRR) construction impacts at the recent Quality of Life meeting; a representative of Empire State Development (ESD), the state authority that oversees/shepherds Atlantic Yards/Pacific Park, acknowledged that the LIRR work is not governed by the project's Memorandum of Environmental Commitments but ESD was trying to nudge the railroad to lessen neighborhood impacts.
At night and on weekends, the Long Island Rail Road (LIRR) will use a portion of the yard lighting near the Atlantic Avenue LIRR Access Ramp for security reasons. This is expected to continue through September. No specific hours were indicated. (This was portrayed in red in the document below, which indicates new work, though it's not new.)
At the Vanderbilt Yard, daytime (presumably weekday) pile drilling will continue in the northeastern portion of Block 1120 (just west of the Carlton Avenue Bridge). (This was portrayed in red in the document below, which indicates new work, though it's not new.)
At the LIRR's East Portal, at the intersection of Atlantic and Vanderbilt avenues, test pit work will be performed during these two weeks to identify National Grid and Con Edison underground gas and electric services nearby. This work will be completed at night because of Department of Transportation permit stipulations. The amount of noise is unclear.
As noted in the two previous updates, LIRR will be turning on yard lighting "this weekend"--presumably, both days?--near the Atlantic Avenue LIRR Access Ramp and possibly in the East Yard (Block 1121).
At the Vanderbilt Yard, weekend daytime electrical utility installations are expected to continue in the yard and in the tunnel.
Building and sidewalk work
The final completion of 38 Sixth Avenue, aka B3, proceeds, with "[l]imited punch listing of residential units."
Sidewalk repair work around the Barclays Center, along Dean, Atlantic, and Flatbush avenue, will be at conducted during daytime, night-time and possibly weekend periods.
No new vertical construction is planned for now.
The demolition that hasn't happened
As stated in the past 50 two-week construction updates, demolition at Block 1120, the railyard block between Sixth and Carlton avenues, could commence upon receipt of Department of Buildings and Department of Transportation permits. A community notice will be distributed. Maybe it's not actually going to happen within this two-week reporting period.
