It seems that the provided Twitter post does not relate to a maintenance report feedback for a public flat house in Singapore. The post mentions "expo mrt interchange cg1 dt35 singapore", which appears to be a location in Singapore, but it does not mention any specific issue or request related to maintenance of a public flat house. Therefore, the answer is "relatedness": False, and the type is "none", with a brief explanation provided.
