Three roles that owners routinely confuse
A strata managing agent is engaged by the owners corporation to administer its affairs, which typically includes holding records, arranging insurances and managing correspondence. A building manager, where one exists, handles day-to-day matters on site. The committee makes decisions on behalf of the owners within whatever authority the scheme's own by-laws and records give it. The three overlap in practice and owners rarely know which is which.
For a contractor the practical question is narrow: whose instruction can be acted on. That is determined by what the scheme has authorised rather than by job title, and it varies between schemes with identical structures. Establishing it at the outset takes one question and it prevents a category of problem that is very difficult to unwind afterwards. Two schemes with identical structures can give quite different answers.
