Régional Transit Extension — Line B.
A multi-station transit extension built through active right-of-way — delivered without a single claim reaching arbitration.
One owner, four prime contractors, zero margin in the schedule.
The authority was extending a live transit line through dense, in-service right-of-way — four prime contractors working concurrently against a fixed revenue-service date, with the public watching every milestone.
CREO was engaged as owner's representative and program controls lead: the constant across all four contracts, accountable for protecting cost, schedule, and a project record that could withstand the claims such programs invariably attract.

The challenge
With four primes on a shared critical path, impacts cascaded across contracts faster than any single team could see. By month nine, the integrated forecast showed the revenue-service date slipping — and the first delay notices were already circulating.
The authority needed one version of the truth: a single schedule and record spanning every contract, current enough to act on and defensible enough to hold up if a claim was filed.
Our approach
- 01Unified the program on one CDEBrought all four contracts into a single common data environment — one source of truth for schedule, cost, and correspondence.
- 02Built an integrated master scheduleLinked the four contractor schedules into one critical-path model, surfacing cross-contract impacts as they emerged.
- 03Drove a structured recoveryRan weekly recovery planning against the integrated model — resequencing work and reallocating float before slip compounded.
- 04Kept the record claim-readyTied every delay to a documented cause as it happened — turning the project record into the owner's protection.
A program brought back to plan.
“CREO gave us a single, trusted view across four contracts. When the schedule moved, we knew why — and we could prove it. That's what kept this program out of dispute.”
