Why it mattered

Transportation work happens in the middle of people's lives: their commute, their freight, their weekends. The best schedule is the one the public barely notices, and the one that holds up if a dispute ever comes.

The challenge

A state transportation department is rebuilding one of the region's busiest interchanges, with fourteen new bridges and miles of mainline.

Traffic has to keep moving through more than twenty construction phases, and incentives and penalties attach to each milestone. Every day of float is worth real money, in both directions.

How we held the date

Our approach, phase by phase.

The same disciplined sequence we bring to every engagement, shaped around what this project needed most.

PHASE 01PHASE 02PHASE 03PHASE 04

PHASE 01Model every phase

Each traffic or track phase modeled with its own critical path and switch date.

PHASE 02Hold third parties to dates

Utilities, railroads and agencies tracked as external milestones with named owners.

PHASE 03Protect the record

Delay events documented as they happen, with time impact analysis while the facts are fresh.

PHASE 04Open to service

Testing, inspections and opening to traffic or revenue service planned in detail.

What changed

The difference we made

Measured the only way that matters: whether the date and the budget held.

Result 01Every phase modeled

Each traffic phase carries its own critical path and switch date.

Result 02Incentives in view

Milestone forecasts show where early-completion incentives can still be earned, and what it would take.

Result 03A record that holds

Delay events are documented as they occur and analyzed through time impact analysis while the facts are fresh.

What we brought to it

Our work in Transportation

2.01.01CPM Scheduling

Critical Path Method schedules engineered so that every date has a reason, every float value means something and every forecast can be trusted in a boardroom.

2.04.02Time Impact Analysis (TIA)

Prospective and contemporaneous TIAs that show, with a clean fragnet and a statused update, exactly what an event does to completion.

2.04.03Extension of Time (EOT)

Preparation, assessment and negotiation of extension of time claims under AIA, ConsensusDocs, FIDIC, NEC and bespoke contracts.

2.01.06Schedule Updates

Disciplined periodic updates that capture verified progress, explain every movement and keep the schedule an instrument of command rather than a record of hope.

2.02.08Forecasting

Risk-informed schedule and cost forecasts, expressed as P50 and P80 ranges, that give executives an honest view of the finish date and final cost.
