As school construction proceeds in base of 662 Pacific St. tower, Sixth Avenue blocked. Why can't neighbors be alerted via regular Construction Update?

The bi-weekly Construction Updates circulated by Empire State Development, the state authority that oversees/shepherds Atlantic Yards/Pacific Park, are mainly concerned with vertical construction overseen by master developer Greenland Forest City Partners and other developers to which it has leased parces. (Here's the most recent example.)

Other work, not so much. 

A case in point: yesterday, Sixth Avenue between Dean and Pacific Streets was blocked off for work on the middle school being built by the School Construction Authority in the base of the otherwise completed 662 Pacific Street tower (B15, aka Plank Road).

A neighbor sent me the photos and video, shot at around 1:45 pm.

As shown in the close-up, as well as the video below, certain items were being delivered through the open windows of the segment of the building devoted to the school, which is five stories above ground, plus a deep cavern below.

Pending questions

How long was the street closed? How much will this recur before the school is completed, in time for its expected September 2025 opening?

The immediate neighbors of the project surely would like to know that, as would those planning to drive through or visit the area. 

Also, there's a fire station around the corner on Dean Street (seen in the video) that often uses Sixth Avenue going north, and a police station below Dean on Sixth Avenue. 

ESD and the SCA should be able to coordinate on this going forward. However, because the SCA doesn't "report" to Greenland, which (as far as I know) produces the Construction Update, the information isn't circulated in the most efficient way.
