What the FEIS said
According to Chapter 17, p. 11 Construction Impacts, of the Atlantic Yards Final Environmental Statement (FEIS), there was reason to expect some after-hours work:
Extended workdays are expected to occur about 40 percent of the weekdays over the course of construction.Notably, that section does refer to "evening and night work" but does not predict the frequency.
...It is expected that weekend work may be required on one weekend day for approximately 50 percent of the weekends over the course of construction and, in exceptional circumstances, two weekend days would be required.
Later, in the section on Construction Traffic Projections, p. 39, the documents offers some more specificity:
Construction Work Shifts and Activities(Emphasis added)
Since a certain amount of extended hours, nighttime work, and weekend construction would likely be required, construction activities associated with the typical day shift (7 AM to 3:30 PM) would generate slightly fewer worker and truck trips than those described above. In general, the extended shift, which may occur once or twice a week during critical construction phases and end at approximately 6 PM, would involve no more than 20 percent of the day shift workforce. Nighttime work (3:30 PM to 11 PM), which may also occur once or twice a week during critical construction phases, could require a separate workforce, totaling no more than 10 percent of the number of day shift workers, to perform specific construction activities at the project site. Weekend activities (7 AM to 3 PM), on the other hand, are expected to occur more regularly throughout construction on one of the two weekend days and require, on average, approximately 20 percent of the regular day shift workforce. Truck deliveries would also take place during these extra work shifts; however, at considerably lower levels than the regular day shift.
Actually, Forest City Ratner has now fixed on not just a second, nighttime shift, but also a third, overnight shift.
"We don’t want to take any chances," Bruce Ratner told Fox 5 on 9/26/11 "It’s going on all the time, on weekends, and after-hours." And, I'd add, with some collateral damage.
The latest reports
One resident of Carlton Avenue between Dean and Pacific streets wrote on Atlantic Yards Watch yesterday:
The movement of construction equipment between 11:00 p.m. and 6:00 a.m. is a fairly regular occurence. It would be a lot less intolerable if they would turn off the claxon that accompanies the moving equipment. It's like the beeping trucks make when going in reverse, only it's ten times louder and more obnoxious.Another resident wrote yesterday on Atlantic Yards Watch:
Also after I reported that Action Enviornmental had stopped emptying the dumpster bins in the middle of the night, they have suddenly started again. 3:30a.m. Friday morning (oct 7) and 4:30a.m. Monday Morning (Oct 10).
Between these two regular occurences, regular sleep is impossible for me, my wife and my infant daughter. I reported these actions of Friday to 311 as separate ongoing occurences.
