From the latest Construction Update: large boom lift being used inside Barclays Center, then moved periodically across the street; tree guards for three trees on Dean Street

For the second straight time, the two-week Atlantic Yards/Pacific Park Construction Update has been released on the Friday before the official Monday date, in this case June 8.

On the one hand, that is welcome--frankly, it should have been the pattern all along, as opposed to distribution on the day it was dated, or a day or two after.

On the other hand, even the early delivery is being used to obscure changes that should have been disclosed earlier. For example, the document distributed yesterday, June 5, contains this passage:
Miscellaneous Work
*During this period it is expected that from June 4 until June 16, work will be done inside the arena which requires use of a 150ft boom lift; this equipment will be removed from the arena when the arena is in use and will be stored as needed in broadcast lot. The work hours will be 4PM-7AM.
As I tweeted yesterday, that left a lot out:
And what, pray tell, is this "miscellaneous work"? Interior roof work?
How complicated and complicating will it be to move it to the broadcast lot *across the street*?
And if this started yesterday, why wasn't this disclosed in the *previous* construction update?
Also, as I wrote yesterday, the state and developer Greenland Forest City Partners belatedly disclosed that Sixth Avenue between Atlantic Avenue and Pacific Street would be closed for an extended period of time.

Some trees protected

The severe narrowing of Dean Street and Carlton Avenue bordering the southeast block of the site has led to damage to several trees, and officials are finally taking steps to improve the situation. The latest alert discloses:
Three-sided tree guards for three trees located on the opposite side of Dean Street across the street from the [B11] site [near Vanderbilt Avenue] will be installed.
New work at B2?

And despite improvements, notably the use of a red typeface and asterisks to purportedly indicate new work being reported, not everything indicated in red and with an asterisk actually is new. Whatever sloppiness or deceptiveness, it disserves the readers.

For example, the latest alert states, regarding the B2 modular tower at Flatbush Avenue and Dean Street:
*Work related to the erection of modules for floors 11, 12, and 13 is continuing during this reporting period.
* Limited interior work will begin on modules that have already been installed. 
Actually, that was announced in the previous alert.

New work at B3

*The approved MPT plan will be installed during this reporting period. This includes the installation of the site fence and gates as well as removal of street lights inside of the B3 MPT.
