KP must be paying his strata manager a fortune if he expects him to be a building manager & handyman as well.
A strata manage role is primarily administrative and financial. You should not expect them to regularly meet and instruct trades persons, carry out site inspections and minor maintenance. They should however know your building and visit every now and then.
Jeff, you are indeed looking for a building manager. You should be able to find one who can offer 8 to 10 hours a week with flexibility in how and when they do these hours.
Another valid suggestion is to employ a cleaner/caretaker who can liaise with tradesmen and identify issues (and preferably rectify minor issues themselves) whilst carrying out their regular cleaning duties.
