Delay analysis

Why did the project finish late — and who caused what?

Delay claims fail when they assert a cause without showing its effect. A credible delay opinion links each delay event to the critical path, using the schedule and the contemporaneous record, period by period.

What delay analysis addresses

  • Whether an event actually delayed completion, or only non-critical work
  • Concurrent delay, and how overlapping causes are treated
  • Extension-of-time entitlement, and the periods involved
  • Acceleration, disruption, and loss of productivity, where the record supports it
  • The difference between planned, as-built, and adjusted schedules

Evidence relied on

Baseline and updated schedules, progress reports, daily logs, correspondence, meeting minutes, change records, weather and site records, and photographs. Where schedules are incomplete, the analysis states what was missing and how that limits the opinion.

How the opinion is presented

In plain language, with a timeline the reader can follow: what was planned, what actually happened, what changed the critical path, and what follows from that for each delay period. Charts and tables are included where they make the analysis clearer, not as a substitute for reasoning.

When to involve a delay expert

Before a claim is framed

Testing whether the record supports a delay position — before positions harden and costs grow.

During a dispute

Providing an independent opinion for negotiation, mediation, arbitration, or court.

After completion

Reconstructing what happened from the as-built record, even where contemporaneous schedules are imperfect.
