I was woken up by incessant jackhammering that sounded like it was right outside my window. Then after it stopped I fell back asleep and was jolted awake again by a bomb like crash that shook the building and even knocked taped up artwork from the walls.
ESDC states that given this is the second complaint they received, they have told FCRC to stop using the equipment they have identified as causing the bang at night. The equipment was apparently a hoe ram. The work being done is apparently not on the "critical path", so the contractors can do the work during the day.
