Multi-contract schedule integration for a tolled managed-lanes corridor built under live traffic.
The agency split 18 miles of managed lanes into five separate construction contracts, with utility relocations and tolling systems integration depending on all of them. Each contractor scheduled its own work. The handoffs between them were not tied together anywhere, and the agency could not see the true opening date.
The approach.
- 01
Interface milestones defined
We mapped every handoff between contracts, utilities and tolling as a shared interface milestone with an owner and a date.
- 02
One integrated schedule
All five contract schedules were linked in Primavera P6 through those milestones, giving the agency one corridor-wide critical path.
- 03
Traffic stages in the logic
Lane closure windows and traffic switches were modeled as constraints, so resequencing proposals were tested before approval.
- 04
Time impact analysis on delays
Each delay event got a time impact analysis, so the agency knew whether it touched the opening date before negotiating.
The outcome.
“Five good schedules can still add up to one late corridor. The risk lives in the handoffs, so that is where we looked.”
