What was at stake.
The river intake could only be built in low-water months, and missing one season meant waiting a full year. The plant itself had to be commissioned and producing water before the old permit expired. The contractor schedule treated the intake as ordinary work.
How we controlled it.
What our schedulers and cost engineers did on this project.
River windows
Intake cofferdam and in-water work were tied to seasonal windows in P6, so a missed window showed its full cost immediately.
Critical path focus
Two-week updates tracked float to the intake windows and to first water, the two dates that decided everything.
Startup sequence
Filters, chemical feed and SCADA were commissioned in a planned order with the operators, not in the order they finished.
Change log
Every change order was logged with its cost and schedule effect, and the log was reconciled with each pay application.
The result.
A river gives you a few months a year to work in it. The schedule had to respect the river first.
