Lessons Learned
What hurt
Refinery cogen access/permitting was the long pole, not the turbine work.
Client feedback
Bayou's EHS team praised our permit-readiness; it smoothed the next mobilization.
Assumptions / what to do differently
Build the safety/permit hours into the bid explicitly on refinery cogen sites — they're real and billable.
