It seems that the Twitter post you provided does not mention anything related to a maintenance report for a public flat house in Singapore. The post simply mentions "ifly singapore sentosa island singapore" and does not contain any information that would suggest it is a maintenance report. Therefore, the answer is that the post does not relate to a maintenance report for a public flat house.
