It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The term "national library building" does not mention anything about public housing or maintenance reports, and it is likely that the post is referring to the National Library Building in Singapore, which is a different entity altogether.
