It seems that the Twitter post you provided does not relate to a maintenance report feedback to a public flat house. The term "31st collin grille" does not appear to be a common term related to public housing or maintenance issues, and it does not provide any specific information or context that would suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
