Lesson 6 of 15 · Planning
Who should I engage?
Design, construction, statutory submission and licensed trade work are different responsibilities.
Designer and contractor roles
An interior designer may develop space and finish proposals. A renovation contractor coordinates and carries out the agreed work. The scope, authority to instruct subcontractors, and responsibility for drawings or site supervision should be written down.
Qualified and licensed roles
A Qualified Person is a registered architect or Professional Engineer acting within the applicable submission role. EMA says electrical work should be carried out or supervised by a Licensed Electrical Worker. PUB requires Licensed Plumbers for regulated water service and sanitary plumbing work, while listing limited simple works that others may perform.
