Yeah, I hear it every morning too, right outside the apartment. I can turn my alarm clock off now, probably pack it away. I don't expect the whistling and chanting to go away anytime soon at least until the building is finished. My sleeping pattern is completely messed up and I'm getting delirious. As annoying as it is, starting to get funny... I heard it in the first "rat" chant today, the guy sounded fatigued almost hungover from the night before. I really do hope they get a sore throat, preferably bronchitis. I do notice they have a water cooler, I may consider filling it with RAT POISON when they're not looking.
