Hi,
I just bought an 4A HDB at 11th floor, during renovation, found that sometimes there will be buzz noise in my living hall area, i also found that the floor is vibrating slightly. Then after that I found there is one side of the wall that is sharing with the next door neibougher is also vibrating,
I guess the floor vibrating is coming from the wall.
Need HELP, anybody know where is the noise & Vibrating source???
Thanks a lot.
