I dont know anything about your apartment. But I'm sure you'll watch out for water pipes. We had someone on around our 30th floor drill into the ceiling right into a water pipe and it flood like a hundred units below. It also took out all 3 elevators in the building. There was no elevator service for almost a week. People were ****ed. Dozens of apartments had to replace their drywalls. I think it must have cost hundreds of thousands in repairs. I can't remember who ended up paying for it.
