A €31M grid expansion project had 14 subcontractors and complex interdependencies. When one supplier started slipping on delivery timelines, the cascade effect was invisible in the project plan.
The PM was tracking milestones in MS Project, but the cross-supplier dependencies weren’t modeled. By the time the delay would surface in the steering meeting, 3 downstream workstreams would already be affected.
In infrastructure projects, a single supplier delay can cascade into months of lost time and millions in overrun. The pattern was forming — silently.
Primary transformer supplier confirmed delivery delay on 3 of 8 components. Trend accelerating over past 2 reporting cycles.
Delayed components feed into civil works, commissioning, and grid connection workstreams. Cascade would add 6–8 weeks to overall timeline.
Extended site operations and standby costs beginning to accumulate. At current trajectory, budget overrun of €3.8M projected by Q3.
“Infrastructure projects have so many moving parts. Praeveo showed us the cascade effect before it happened — that’s worth millions.”— Head of Project Delivery, European Energy Company
