Working checklist

• Define safety and serviceability objectives
• Build a defect map and inspection plan
• Compare intervention options over the remaining life

Technical and contractual decisions become harder to defend when the underlying observations, assumptions and approvals are mixed together. A disciplined workflow keeps each layer visible and gives the project team a shared basis for action.
