It seems that the Twitter post you provided does not mention anything related to a maintenance report feedback for a public flat house. The term "pcaf" is not a common term in Singapore, and it is unlikely that it refers to a public flat house. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
