What are typical programme durations for infrastructure?

Last reviewed July 5, 2026

Typical programme durations for infrastructure projects vary widely. Smaller projects might take a few months, while larger ones can stretch over several years. Factors like complexity, site conditions, and approvals play big roles in the timeline.

Key points

  • Small projects: 3-6 months.
  • Medium projects: 1-2 years.
  • Large projects: 2+ years.

You'll find that infrastructure projects often depend on the type and scale. Roads and bridges might have different timelines than utilities or rail. Always factor in design, approvals, and potential delays when planning your schedule.
