The brief

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.

Scope of services
  • Program & project controls
  • Owner's representation
  • Common data environment (PMIS)
  • Schedule intelligence & risk
  • Document control
  • Claims avoidance & support

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

  1. 01
    Unified the program on one CDE
    Brought all four contracts into a single common data environment — one source of truth for schedule, cost, and correspondence.
  2. 02
    Built an integrated master schedule
    Linked the four contractor schedules into one critical-path model, surfacing cross-contract impacts as they emerged.
  3. 03
    Drove a structured recovery
    Ran weekly recovery planning against the integrated model — resequencing work and reallocating float before slip compounded.
  4. 04
    Kept the record claim-ready
    Tied every delay to a documented cause as it happened — turning the project record into the owner's protection.
The outcome

A program brought back to plan.

In their words
“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.”
