It seems that the Twitter post "ib hq singapore" does not relate to a maintenance report feedback to public flat house in Singapore. The term "ib hq" is likely an abbreviation or acronym that is not related to public housing or maintenance reports, and therefore does not fit into any of the categories I have identified.
