It seems that the post you provided does not contain any information related to a maintenance report for a public flat house. The post only mentions "east coast park" and "marina cove", which are locations in Singapore, but do not provide any information about a maintenance report. Therefore, the answer is "relatedness": False, and the type is "none".
