Lessons Learned
What helped
Coastal's outage planner gave us early borescope access — we caught R1 bucket distress before mobilization and re-planned the disassembly.
What hurt
Even with early access the added bucket scope grew disassembly ~4 days; the bid hours didn't carry that contingency.
Client feedback
Plant manager valued the daily findings reports and no-surprise change orders.
Assumptions / what to do differently
Make confirmed pre-outage borescope access a hard gate before bidding 7FA major hours.
