The Challenge
The contracted as-built drawing set is rebuilt by hand at the end from marked-up paper prints, when pressure is highest and memory is oldest. It also sits directly in front of the final payment.
How It Works
- Ingests issued drawing sets with revision history, site mark-ups and yard correspondence.
- Tracks as-drawn against as-built as it occurs and reads yard messages for approval status.
- Maintains a current-revision register with stated confidence on class status, and indexes it.
What It Removes
- As-built set rebuilt by hand after handover
- Work done twice from a superseded drawing
- Class approval status guessed rather than known
Input Data RequirementsIssued drawing sets with revision history, site photographs and mark-ups, yard correspondence on drawings and approvals, older records as scans
Output FormatCurrent-revision register per drawing, as-drawn versus as-built difference list, class status per drawing with stated confidence, past-work library
“The final drawing set is nearly finished before the ship is - and the last payment stops waiting on it.”
