It seems that the tweet "rock school singapore" does not relate to a maintenance report feedback for a public flat house. It is not a specific location or facility related to public housing, and it does not mention any maintenance issues or requests for fixing. Therefore, the answer is "relatedness": False, and the type is "none".
