@just get on with it said:
KP must be paying his strata manager a fortune if he expects him to be a building manager & handyman as well.
Neither the SM nor a BM will actually do the repairs they will charge for their time and then hire someone to actually carry out the repairs.
Bear in mind our SM charges $200 / hour for extra services so you can expect to pay a BM 8 hours x $200 approx $1600 per week plus the cost of the tradesman to actually do the repair.
Part of the SM job is to organise quotes for repairs when informed about them so if you have absoloutely no resident who is capable of phoneing the SM (or employed handyman) and telling them that a light bulb needs replaceing then yes you need a BM.
