The contractor's crew will try to reduce the noise as much as possible by using their radios instead of shouting, and by muffling the back-up warning alarms on the trucks. Unfortunately, they say that the 7900 Wisconsin site requires the trucks participating in the pour to go into reverse at least once.
Residents of Fairmont Plaza, 7770 Norfolk and - to a lesser extent - the Bainbridge Bethesda and The Whitney are the most likely to be affected by the noise prior to 7:00 AM Wednesday. I can say that I previously had heard this pour might take the whole night, so starting at 4:00 is at least a significant improvement over that scenario.
