At Ternavell Infrastructure in 2009, I approved a project-information account containing ninety-six floor plans. The selection treated the latest uploaded file as the latest approved version. A review against the revision register identified twenty-eight of those plans as superseded. Upload order had been used as a shortcut for a documentary status it did not establish.
Evan Tarswell challenged the selection by returning to the revision evidence. My initial preference had been to keep the latest-file convention because it was easy for users to understand and maintain. I had not adequately distinguished a recent upload from an approved revision. An older file could be uploaded again, or a new file could exist without the status the report implied. The convenience of a chronological file list did not make it an approval record.
I accepted responsibility for the assumption and supported A$480000 of review and correction. We retained the approved revision reference, source, date and document status instead of deriving approval from upload position. The twenty-eight superseded plans were identified in the reviewed account. The other sixty-eight were not flagged by that exercise, but that fact was not presented as a universal certification that every drawing was current or correct for every purpose. Project engineering and the responsible document owners retained their approvals.
The change gave users a more defensible version account and required me to explain why the earlier selection rule was inadequate. It did not amount to a structural inspection, safety assurance or confirmation of as-built conditions. The case remains in my public narrative because the data function can make a consequential documentary claim without changing the contents of a drawing. My error was in the status I allowed the account to imply. The correction needed to preserve the evidence of approval, not merely replace one convenient latest-file list with another.
