What was at stake.
The tax credit deadline was fixed, and missing it would change the project's economics. Turbine deliveries came in convoys, crane moves between pads took days, and high winds stopped lifting. The developer needed a schedule that modeled all of it honestly.
How we controlled it.
What our schedulers and cost engineers did on this project.
Pad by pad
Each turbine pad had its own foundation, delivery, erection and commissioning activities in P6.
Crane path
Main crane moves were scheduled as a route across the site, so one late pad showed its effect on the rest.
Wind risk
Monte Carlo analysis on wind standby days showed how much margin the deadline really had.
Substation first
The collector substation and interconnection were scheduled so turbines could be energized as they were completed.
The result.
Wind is both the product and the risk. We scheduled the crane around the wind, not the other way round.
