What was at stake.
Gas and chemical systems need high-purity welding, testing and certification before any tool can run. The yard schedule had certification at the end with a fixed duration that nobody had checked.
How we controlled it.
What our schedulers and cost engineers did on this project.
Certification broken down
Purge, leak test, purity testing and certification were split by system and given durations from real data.
Weld progress tracked
High-purity weld counts drove earned value, so progress could not be overstated.
Changes priced
Every change to the gas list was priced and scheduled within days, keeping cost and time honest.
Handover by system
Each system was handed over as soon as it was certified, letting early tools start sooner.
The result.
Certification was a single bar on the old schedule. We turned it into the dozens of steps it really is.
