Construction noise at obscene hours

Heavy and very loud construction noise on a daily basis at ridiculous hours. On 8/18 there was heavy and very construction at 3:30 AM not allowing many in the neighborhood to sleep including many elderly residents. August 20th, heavy jackhammering starting before 6:00 AM and continuing through the morning. Tuesday, August 21st very loud chainsawing occurring. There has been a lot of the construction noise during the day for months, and that is to be expected with large projects. But it seems as the deadline for completion is getting near they're getting desperate to finish, the community should not have to suffer even more because they mismanaged their schedule.
