schedule overrun running to 20 months — yes, not days, not weeks, but months. Bent Flyvbjerg and Dan Gardner at the University of Oxford analyzed more than 16,000 major capital projects globally and found that only 8.5 percent — roughly (just) 1 in 10 — were delivered on time and within budget.
These numbers deserve a pause. If you are running a portfolio of ten projects, statistical expectation says nine of them will miss cost, schedule, or both. And this is not driven by complexity alone. Flyvbjerg's research is explicit: the primary driver of overrun is not a technical risk. It is an optimism bias combined with inadequate systems for tracking and responding to what is happening on a project in real time.
Here is what those numbers look like on the ground. A project is awarded. The BOQ that anchored the bid becomes the baseline for detailed engineering. Procurement is engaged to take the finalized scope to market. Before construction begins, the project schedule is reviewed, confirmed, and agreed across stakeholders. Finance is tracking all of this across an ERP, project management tools, and status reports that different teams compile from different sources.
Somewhere in the execution phase, a project review raises questions that are difficult to answer. Projected completion cost is now higher than the original forecast. The schedule reflects agreed milestones, but progress on the ground has moved at a different pace. These are not unusual situations, but their recurrence can really set the project back. So, it is important to understand the root cause which is often structural: the project is being managed in stages that do not share information as fluidly as the work itself requires.
The question is not whether your next project will be complex. It will be. The question is whether the systems running it can keep pace with that complexity — from bid to handover.
The EPC Project Lifecycle Problem That Gets Neglected
EPC project delivery is inherently a lifecycle process. It runs from bid through engineering, procurement, construction, commissioning, and handover — a sequence that can span years and involve hundreds of contractors, thousands of documents, and tens of thousands of individual decisions. The challenge is not that any single phase is unmanageable. The challenge is that each phase generates decisions, commitments, and outputs that the next phase must build on, and those handovers can be messy and inefficient. What engineering commits to may create hard constraints for procurement. What procurement does may affect the construction schedule. These dependencies are understood in principle. But they are harder to manage in practice.
The gaps appear not within any single team's work, but in between phases — where a decision or outcome from one part of the project has not yet reached the people it affects in another. When engineering revises a design, procurement may not know in time to adjust a purchase order. When a procurement order is delayed, the construction schedule may not reflect the impact for weeks. When a risk is identified at site level, it may sit in a field report that only gets read during the next quarterly review. Every one of these gaps is a point where the lifecycle thread breaks — where the continuity of information that should connect intent to execution to outcome is severed.
The downstream effects compound. In EPC, every scope creep must go through formal engineering review and approval process. But when those changes are not tracked against the original cost projections in real-time, the financial impact can slowly accumulate and can be huge. WIP accounting drifts from actuals. Billing cycles lag behind construction progress. By the time any of these surface in a financial report, the project is already in fire-fighting mode.
The Digital Thread: Connecting the Lifecycle, Not Just Digitizing It
The concept of a digital thread originated in aerospace and defense manufacturing, where the cost of lifecycle disconnection — in safety terms, not just financial ones — was too high to tolerate. The core idea is straightforward: a digital thread is a continuous, connected flow of data that runs through every phase of a project's life, from design intent through to operational reality. Not a single database or a reporting layer, but live connective tissue that allows information generated in one phase to be immediately visible and actionable in another.
