It seems that the Twitter post "ub 1 singapore" does not relate to a maintenance report feedback to public flat house. The term "ub 1 singapore" does not appear to be a specific location or facility related to public housing in Singapore. Therefore, the answer is "relatedness": False and "type": "none".
