From the latest Atlantic Yards Construction Alert: B2 up to 189 modules; constriction of Atlantic Avenue begins Thursday; two nights of overnight work

According to the latest two-week Atlantic Yards Construction Alert, dated and distributed July 7 by Empire State Development after preparation by Forest City Ratner, major work will finally start on or around Thursday, July 10 to enable railyard renovations and later work on the Barclays Center's green roof.

That work includes constricting Atlantic Avenue for two years (3 westbound lanes and 2 eastbound lanes) near the area, pile drilling on Pacific Street, and the removal of concrete medians on Atlantic. Beginning Thursday--Wednesday night?--there should be two nights of work on Atlantic. (The impact is unclear, but such overnight work can be noisy and/or bright.)

(The previous alert had indicated June 30 for the work, but the July 10 date was announced last week, with far less detail on the actual work being done.)

Mods delivered

Over two weeks, the number of modules delivered to the B2 residential tower rose from approximately 165 to 189, which means 24 were delivered and installed over two weeks, an average of 2.4 per business day. (That's more than in most two-week periods, though 48 were delivered and installed in the previous period.) 

The building requires about 930 modules. At 2.4 modules/day, the installation would be done in 31 weeks, which would be well before the announced December 2015 opening date, which was nudged back a year. (Presumably there are more expected complications and/or testing requirements.)

The below items are verbatim excerpts from the Construction Alert.
