Domestic Building Practice and Management: Running a Compliant, Safe Project
What this domain tests
This domain covers how a builder plans, contracts, supervises and delivers domestic work lawfully and safely. Candidates must understand the contractual framework (written domestic building contracts, scope, variations, progress payments, completion and defects liability), statutory obligations (work health and safety, insurance and home warranty where applicable, licensing), and quality management (documentation, inspection and test plans, hold points, record keeping).
Core practice concepts
Know the project lifecycle: estimating and tendering, programming, procurement, site establishment, supervision, quality control, practical completion and handover, then the defects liability period. Understand supervision duties: verifying trades are licensed, coordinating inspections with the certifier at mandated stages (e.g. footing, slab, frame, waterproofing, final), and maintaining records. For WHS, know the hierarchy of control, safe work method statements for high-risk work, site induction, and consultation. For contracts, know that variations should be written and signed before work proceeds, and that progress claims must reflect work actually done.
Traps in exam questions
Common traps include treating a verbal variation as automatically binding, assuming the certifier supervises quality (they inspect for compliance, not workmanship), confusing practical completion with final completion, and ignoring that a builder must not conceal work before required inspections. Questions may also test who holds the primary duty of care (the person conducting a business or undertaking) and when a SWMS is required.
Worked example / rule of thumb
Rule of thumb: no inspection, no cover-up. Example: before pouring a slab, confirm the certifier's pre-pour inspection is booked and passed, plumbing and termite systems are signed off, and photographic records are filed. If a client requests an extra power point after frame stage, issue a written variation with price and time impact, have it signed, then schedule the electrical work.
