It seems that the tweet does not relate to a maintenance report feedback for a public flat house in Singapore. The tweet simply mentions the word "causeway" which could refer to a road or a bridge, but it does not provide any additional context or information that would suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house in Singapore.
