Atlantic Yards/Pacific Park graphic: what's built/what's coming + FAQ (pinned post)

From the latest Construction Alert: 5 am concrete pour Tuesday; 550 Vanderbilt to reach 18th floor; demo on Dean

According to the latest two-week Atlantic Yards/Pacific Park Construction Alert (below), for the two weeks starting Monday Nov. 23, a potential 14-hour job--the pouring of the center mat foundation for the B3 tower at Dean Street and Sixth Avenue--could begin at 5 am.

No date was attached. By early afternoon, just a few hours after the alert was circulated, the 78th Precinct tweeted that the pour would occur on Tuesday, Nov. 24, and that concrete trucks would enter via Pacific Street and back into the 6th Avenue gate--a somewhat confusing piece of information. (Should people avoid the block?)

The Construction Alert, which is often issued on the day it's dated, or even the day after, was circulated yesterday by Empire State Development after preparation by Greenland Forest City Partners. Surely they recognized that they had to get the word out ahead of time. But shouldn't this minimal amount of lead time be routine?

A demo, and a top-out 

Note that demolition of three houses on Dean Street east of Sixth Avenue will begin during this period. They've already been allowed to deteriorate.

Note that the 550 Vanderbilt Avenue condo building, aka B11, is expected to top out "with 18th floor which is expected to be complete by the end of next week." (Not sure whether "next week" means the end of the week beginning Nov. 30, or the week after that.)

After-hours work

Also note that "Saturday work to address field conditions" is expected at the B2 (Dean Street and Flatbush Avenues), B3, and B15 (Pacific Street and Sixth Avenue) sites  "Saturday work and work up until 9 pm during weekdays to address field conditions" is expected at the B14 tower, at Carlton and Vanderbilt Avenues.

Weekend electric utility work will continue in the LIRR tunnel and may begin in the Vanderbilt Yard itself.

Below are other instances of new work in the project, taken verbatim from the alert.

B3 - 38 Sixth Avenue
• Previously scheduled temporary electric work was postponed but will take place during this reporting period. This will involve a two day closing of the sidewalk along Dean Street, which will be done in accordance with obtained DOT permits.
• Framing and pouring of the south and east foundation walls will take place this reporting period.

Arena Green Roof
• Replacement of Barclay’s roof identification will be taking place during this reporting period.

Yard Work
• Weekend Yard/West Portal work that requires coordination with LIRR operations may be performed during the reporting period. Work is expected to include West Portal Structural Column Steel footing/foundation forming, rebar installation, and concrete work.
