From the latest Atlantic Yards/Pacific Park Construction Alert: mobile cranes (of uncertain size) added to B11 and B14 construction sites

The latest Atlantic Yards/Pacific Park Brooklyn Construction Alert, covering the two weeks beginning yesterday and delivered after 4 pm yesterday, revealed that mobile cranes have been or will be added to the B11 and B14 sites, at Dean Street and Vanderbilt Avenue and Dean Street and Carlton Avenue.

The size of the cranes, however, was not revealed.

The Construction Update, released by Empire State Development (ESD) after preparation by Greenland Forest City Partners, is an "effort to keep the Pacific Park Brooklyn Community aware of upcoming construction activities."

As in the most recent documents, the update uses an * and red type to indicate new work being reported. However, the update is unclear. For example, the document in one place states that Saturday work "will commence," but the previous document said the same thing. Does that mean the previous prediction didn't pan out, or did they not correct the document to state that Saturday work "will continue"?

Below are verbatim excerpts, with some commentary by me, in italics. The headings are bolded, and I have also bolded new information.

B2 - 461 Dean Street, Modular Residential

During this working period:
• Work related to the erection of modules shall continue.
• Interior work will continue on modules that have already been installed.

Note that they are no longer indicating which floors they are working on; previously, they indicated Floors 13 and 14.
B3 - 38 Sixth Avenue

During this working period:
• Excavation and foundation activities have commenced & continue during this reporting period. Work includes drilling of tie-backs for the SOE system, soil excavation and the installation of lagging.
Soil that has been classified as clean or contaminated will be removed from the site as part of the excavation activities and brought to appropriate disposal locations. Protocols for the trucks entering and exiting the site have been put in place. These protocols provide instruction on roadway routing to and from the project site, queuing of trucks while on site and vehicle idling restrictions.
• Saturday work to address field conditions within the site may occur during this reporting period.

Note that the previous alert said Saturday work "will commence."

B11 – 550 Vanderbilt Avenue

During this reporting period:
• *The superstructure phase of construction is continuing, including the use of a mobile crane. During this reporting period, material and equipment will be delivered to site, as well as work related to the construction of the ground floor of the building.
• *Replacement of 16’ chain link gates with 8’ chain link with acoustical blankets.

Note that the previous alert also announced the replacement of the chain link gates. It did not menion the mobile crane.

B14- 535 Carlton Avenue:

During this reporting period:
• Excavation and foundation activities will continue during this reporting period. Work includes drilling of tiebacks for the SOE system, excavation of soil to a depth of 40’ and the continued installation of lagging to the same elevation. Soil that has been classified as clean, contaminated or hazardous will be removed from the site as part of the excavation activities and brought to appropriate disposal locations. Protocols for the trucks entering and exiting the site have been put in place. These protocols provide instruction on roadway routing to and from the project site, queuing of trucks while on site and vehicle idling restrictions.
• *A tie-back drill rig will be demobilized during this reporting period.
• Installation of spread footings and slab on grade is ongoing. A small crane is being used inside of the excavation to assist in concrete operations. *A second small crane will be mobilized on the Carlton Avenue side of the construction site during this reporting period.
• Installation of foundation waterproofing and pouring of foundation walls is ongoing.
• Saturday work to address field conditions within the site will commence during this reporting
period. This work includes all work listed above.

Note that, despite the asterisk, the "second small crane" was supposed to have been mobilized during the previous reporting period. It's unclear whether it was delayed, or the preparer of this document was slopping. 

Also, there was no asterisk regarding Saturday work, because the previous alert also stated such work "will commence." Either it started or it didn't.
