It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "cross street exchange" is not a common term used in public housing contexts, and it does not seem to be a specific location or facility that is associated with public housing in Singapore. Therefore, the answer is "relatedness": False.
