It seems that the tweet does not relate to a maintenance report feedback for a public flat house. The term "terminal 3 Singapore" could refer to various things, including a terminal at a airport, a location in Singapore, or a specific event or activity. Without more context, it is difficult to determine the exact meaning of the tweet.
