It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "terlockdown" is not a common term in Singapore's public housing context, and "shipyardsingapore" does not provide any relevant information about maintenance reports. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house in Singapore.
