Project stages
Inspection scope by board class
274 boards across 127 locations: all main switchboards, plus a sample of MSSBs and DBs per BAC's per-building quantities.
Inspection scope by access route
Tenant boards are coordinated with each tenant ahead of the visit. BAC-direct boards are accessed through BAC.
Inspection programme
Field programme for the 274 nominated boards. Stage 1 covers tenant-coordinated sites; Stage 2 covers BAC-direct sites and is tentative until access dates are confirmed with BAC Operations.
| Stage | Day | Date | Area | Boards | Status |
|---|
Isolation windows (RFQ Addendum 1)
Standard isolations: 6:00 pm – 6:00 am
Car park lighting: daylight hours
International Terminal: 11:00 am – 4:00 pm, with Operations approval
Internal inspection is by escutcheon removal under BAC QTP approval and the project SWMS.
Fleet profile
All 1,116 LV distribution boards in BAC's asset register. The AMP covers the whole fleet for lifecycle and capital planning. Figures are from the desktop assessment and are revised as inspections are completed.
Boards by decade installed
Install year from BAC's register where recorded, otherwise the building's year built.
Desktop risk priority
Desktop screen to direct inspection effort. Not a condition grade.
Asbestos likelihood (desktop, by era)
Desktop screen from install era. Confirmed only by licensed sampling.

Assessment method
How each inspected board is assessed and graded. The method follows BAC's Appendix C condition assessment proforma and Appendix B grading scale.
What is checked at every board: BAC Appendix C themes
Each theme is recorded as OK, Observation, Defect or N/A, with photographs tagged to the BAC asset ID. Observations are noted for the AMP but are not defects.
Condition grade (BAC Appendix B)
Condition confidence
Confidence
Meaning
Inspected
Escutcheon removed and all themes recorded.
Partially inspected
Board visited; one or more themes could not be inspected. Reason recorded.
Assumed
Not visited. Grade set by the engineer from inspected boards in the same building.
Recommended pathway
Retain
Routine planned maintenance.
Maintain
Rectify defects and monitor condition.
Modify-to-extend
Board can safely accept modification for additional capacity.
Replace
Plan replacement in the capital works program.
Defect priority (BAC Appendix C)
Priority
Meaning
Target timeframe
Immediate
Unsafe condition requiring urgent isolation, make-safe or access restriction.
Make safe same shift; BAC notified same day
High
Significant safety, compliance or reliability risk; plan corrective works as a priority.
Within 3 months
Medium
Degradation or non-conformance requiring planned maintenance or rectification.
Within 12 months
Low
Minor defect or improvement; address in routine maintenance or at next renewal.
Next PM or renewal
Every defect carries a standard recommended action and the relevant AS/NZS clause. Where a visual inspection cannot confirm compliance (RCD coverage, discrimination, arc flash labelling), a follow-up investigation is recommended and rolled into a forward testing program.
