From the latest Construction Alert: second shift for steel not expected, crane planned for Flatbush Avenue, pile driving at Carlton Avenue Bridge

According to the latest two-week Atlantic Yards Construction Alert (below), dated October 24 and distributed October 25 by Empire State Development (after preparation by developer Forest City Ratner), there are a few notable changes:
  • a second shift from the steel erector is not expected in this and next week
  • installation of the arena facade will require a crane to occupy part of northbound Flatbush Avenue
  • there will be additional pile driving (and, presumably, noise to neighbors) at the Carlton Avenue Bridge.
The text I've excerpted below mainly concerns text in the document that differs from the previous alert, with the new language in bold.

Deliveries & Site Access
Preparation for the erection/installation of a material hoist at the intersection of 6th Avenue and Pacific Street has been revised and is now projected to commence during the month of November. It will be located just south of the existing construction ramp into the project.
Steel Erection and Stadia Installation
No second shift work by the steel erector/stadia installer is expected in the next two weeks. This will be re-evaluated after this period. Some weekday overtime may be needed and work on Saturdays will continue
Façade Installation
The façade erector will continue the installation of erection clips on the Flatbush Avenue elevations during this reporting period. The façade erector will continue with installation of erection clips along the 6th Avenue elevation this reporting period. Installation of the erection clips may be started on the Dean Street elevation during this reporting period
The installation of façade panels at the street level and at the Upper Concourse levels on Atlantic Avenue has been completed. Contractor will return to install the façade panels at the uppermost elevation and in area of material hoist at a later date.
The installation of curtain wall and curtain wall/lattice panels will continue on the Flatbush Avenue elevation during this reporting period. A portion of this installation is expected to continue on a third shift this reporting period starting on or around October 31 where the crane will occupy part of northbound Flatbush Avenue. The intent is to allow for minimal interference with pedestrian and vehicular traffic on the Flatbush corridor. This permit has been approved by DOT with the DOB crane permit and the MPT was revised the week of October 3rd.
Waterproofing & Fireproofing
The installation of temporary weather walls (visqueen & tarps) as well as temporary rubber roofing, to provide protection through the winter months, is expected to begin this reporting period
Mechanical, Electrical, & Plumbing
 The gas service has been tied into the arena gas meter (Thursday 10/13/11).
The domestic water service has been tied into the arena (Friday 10/14/11).
Carlton Avenue Bridge
Posillico/Tully will continue working on the lagging and tieback work at the north east gas station location and continue to lower the grade there. Additional pile-driving will resume in this area below grade during the next two weeks. The excavation and associated support work will be on-going for the next couple of months.
Utility work
The sanitary sewer and water taps on Dean Street are complete. The contractor has called for a DEP inspection and will pave the area after approval. All of the water and sewer work in this area must be performed at night between 10 PM and 6 AM per DOT stipulations. • Storm water discharge into the sewers is still in progress. The discharge at Flatbush Avenue is complete but has not yet been inspected. The discharge at 6th and Pacific Streets will be made during later October/November. Work in this area will be performed during night time hours, 10 PM to 6 AM, to coordinate with arena work scheduled and DOT stipulations.
Anticipated Nighttime & Weekend Work

While this text has not changed, it also shows some carelessness by those producing and distributing the report, as indicated by the text in bold, which references dates that have already passed.
During this reporting period the following work will be performed either at night or during the weekend as noted. All work will be done pursuant to approved permits:
• Long Island Rail Road/Vanderbilt Yard/ Carlton Avenue Bridge:
o Construction hours are 6am – 4:30pm.
o Construction work will take place on Saturdays during the hours of 7am – 5:30pm for a
period of at least three months. Saturday work is expected to continue for this reporting
period.
o Construction work may take place on Sundays during the hours of 8:00 AM – 4:30PM for a period of at least three months. The work being performed will be confined to two areas:
 The LIRR car shop for the installation of the roof structural support system, demolition of existing yard-side wall, excavation and construction of new deeper footings.
 The area of the former Northeast Gas Station (Block 1121, lot 42) for installation of
lagging and tiebacks for the support of excavation.
• Arena Site:
o Arena weekend work will be scheduled no later than close of business on the preceding
Thursday, where make-up work due to weather or other delays makes it necessary. Saturday work is expected to continue for this reporting period.
o Subject to receipt of permits, a second shift shall be continued throughout this reporting
period, from 3 – 11 PM, Monday-Friday only. Also subject to receipt of permits, a third shift shall be instituted during this reporting period, from 11 PM – 7 AM, Monday –Friday only.
o Hunt has been granted a permit to allow for deliveries from 6 AM to 7 AM to the Arena site from the dispatch center. This work allows for an additional hour of deliveries to take place outside the neighborhood peak traffic patterns and reduce congestion and interference with the local traffic.
o The Developer has been requested to advise ESDC and STV of what contractors will be
working over the weekend and what they will be working on. The second shift arena
contractors are noted within the arena summary above.
• NYC Transit Improvements:
o Temporary concrete road decking is substantially complete, however, in the event there is a need to do any related work, such work will be performed at night per DOT regulations.
Traffic will be restored every morning according to DOT stipulations.
As noted above, work will be performed to repair steel within the BMT Tunnel and will be conducted under a BMT GO during the weekend of October 15th as approved by the NYCT. Additionally, work related to of the BMT structure and below grade concrete, steel and MEP work may be conducted on Saturday October 22nd during this reporting period.
• Block 1129 – staging area:
o Contractors conducting night work may have cause to enter and exit this area as it serves as a staging and material/equipment storage area.
• Off-Site Mitigation work:
o Work taking place at Pacific/Flatbush and 4th/Pacific will be done during the overnight
pursuant to DOT permits. Work will be concluded by 6 AM so that related MPT is removed for the morning rush hour.
