Mega projects and the limits of traditional delivery

Mega projects and the limits of traditional delivery

Why sequential models may not be enough for today’s biggest infrastructure projects.
20 April 2026

As infrastructure programmes grow larger and more complex, traditional delivery models are being pushed to their limits. Engineer, procure and construct (EPC) approaches are typically sequential, yet the conditions facing many large infrastructure projects today rarely are. This growing gap between how projects are structured and how they are expected to move is reshaping delivery decisions from the outset.

In part 2 of our Delivering Mega Projects series, Carl Parlongo examines why relying solely on sequential delivery models can create schedule pressure and cost risk.

Get direct insights on:

  • why doing things “in order” can slow projects down
  • how parallel delivery shifts time, cost and risk dynamics
  • what shared risk really looks like on major projects

Missed part 1? Watch it here to explore the delivery bottlenecks slowing mega projects, and the scale of new transmission needed to support decarbonisation.
