Onsite building requirements

Supervision

It is your responsibility to supervise and coordinate tradesmen working on site, and this includes any defects in subcontractors’ work. 

If you are a nominee or site supervisor, you must ensure the work done is supervised by an appropriately licensed person.

Supervision and construction managers 

As a construction manager, your obligations are the same as for a licensed contractor. You must make sure that any work carried out by licensed contractors for a principal (under construction management trade contracts) is supervised by an appropriately licensed person.

Cost of poor supervision

Costs to fix defective or substandard work can be high. In extreme cases, fixing poor quality work has forced licensed contractors to close their business and/or declare bankruptcy. It is in a contractor’s best interest to be diligent in supervision and quality control.

See the Supervision of Building Work fact sheet (PDF) for the Supervisor’s Checklist for Domestic Building Work.

Quality control

You should carry out regular on-site inspections with your client to ensure work meets acceptable standards. If the homeowner would like a more technical person to inspect the work, it may be worthwhile for them to use a private Building Consultant to monitor the job on their behalf and to raise any issues. Any particular requirements for quality and finish (e.g. type and number of coats of paints) should be included in the contract.

Is a certifier responsible for supervision?

No. You and the owner are responsible for ensuring the building work meets acceptable standards. A certifier must act in the public interest in regard to health and safety but can’t supervise or report on the quality of work on an owner’s behalf. For more information, see Roles and responsibilities of a certifier.
