It seems that the tweet "ub 1 singapore" does not relate to a maintenance report feedback to public flat house in Singapore. The tweet does not mention any specific details or issues related to public housing or maintenance, and does not appear to be a complaint or feedback of any kind. Therefore, the answer is "relatedness": False, and the type is "none".
