Schedule Delay Analysis Services (TIA & Windows Analysis)

When a project delay turns into a contractual dispute, the schedule becomes evidence. We reconstruct and analyse it with the rigour a claim, an extension-of-time request, or an arbitration actually requires.

Method matters as much as the answer

A defensible analysis, not just a number

Delay analysis is only as credible as the method behind it. We apply recognised approaches — Time Impact Analysis (TIA) for prospective, event-by-event assessment, and Windows Analysis for retrospective, period-by-period examination of an as-built schedule — selected based on data availability and the contractual framework in play.

The deliverable is built to withstand scrutiny: a documented baseline, a traceable update history, and a clear separation between concurrent delays, critical delays and float consumption.

Common contexts

When you need a formal delay analysis

Extension of time request

You need to substantiate an EoT claim with a schedule-based demonstration of critical delay and entitlement.

Contractual dispute

A disagreement over responsibility for delay is heading toward negotiation, adjudication or arbitration.

Independent review

You need to assess the strength of a delay claim submitted by a counterparty before responding.
