Practitioner evidence
Practitioner evidence cases
The following case summaries are drawn from practitioner experience. They illustrate the type of existing-building judgement required in advanced residential renovation work. They are presented as practitioner evidence, not verified regulatory findings.
Case 1: Severe subfloor decay — "piano floor"
Original apparent scope: Localised flooring repair.
Discovery: Extensive concealed decay, failed ventilation and structurally compromised floor framing.
Decision: Expand investigation to sound structural boundaries and rebuild rather than patch.
Capability demonstrated: Hidden-condition diagnosis, structural risk recognition and scope reassessment.
Case 2: Major termite rectification
Original apparent scope: Localised termite or external-wall repair.
Discovery: Progressive concealed damage extending through adjoining structural areas.
Decision: Stage investigation and reconstruction while determining the real damage boundary.
Capability demonstrated: Termite warning-sign recognition, sequencing, temporary stability awareness and escalation.
Case 3: Bathroom hidden-condition escalation
Original apparent scope: Standard bathroom renovation.
Discovery: Rot, damaged floor or wall substrates, unsafe services and unsuitable wet-area conditions.
Decision: Stop finishes, rectify structure, engage relevant trades and revise the sequence.
Capability demonstrated: Wet-area substrate assessment, multi-trade coordination and consumer scope communication.
Case 4: Speech-pathology conversion
Original apparent scope: Internal fit-out based on supplied plans.
Discovery: Undocumented walls, bricked-up construction and a concealed chimney conflicting with the planned stair.
Decision: Stop the planned sequence, investigate and redesign the work path.
Capability demonstrated: Existing-building interpretation, adaptive planning and professional coordination.
Case 5: Cladding and asbestos escalation
Original apparent scope: Replace ageing cladding.
Discovery: Asbestos, missing insulation, deteriorated framing and unsuitable substrates.
Decision: Escalate hazardous-material removal, repair the envelope and revise scope before installing new cladding.
Capability demonstrated: Hazard recognition, specialist handoff and building-envelope sequencing.
