Which combination of duties is described for the principal contractor on a domestic project?

• A. Health and safety duties only
• B. Administrative duties only
• C. Design duties only
• D. Client duties and own principal contractor duties

Answer: (D)

On a domestic project, the principal contractor must handle their own construction-phase duties and may also take on the client’s duties when the private homeowner can’t fulfill them. This means they plan, manage and coordinate safety during the work, prepare a construction phase plan, ensure welfare facilities, and stay in touch with the client to keep safety arrangements and information up to date. If the homeowner is unable to provide the necessary information or reach the required safety standards, the principal contractor steps in to carry out those client responsibilities as well, ensuring the project remains compliant and safe.

This is why the option describing both the client duties and the principal contractor duties is best. The other options focus on a single area such as safety alone, administration alone, or design work alone, but the principal contractor’s role on a domestic project inherently combines their own safety and coordination duties with the ability to fulfil the client’s duties when needed.
