It seems that the tweet you provided does not relate to a maintenance report feedback to public flat house. The tweet mentions the Changi Airport control tower in Singapore, which is an airport facility and not a residential building or a maintenance report. Therefore, the answer is { "relatedness": False, "type": "none", "explanation": "This is not related to public housing or maintenance report feedback." }.
