How to use this template
What it helps you decide
The brief separates contractual questions from demonstrated programme effects. It exposes unreliable schedules, competing causes and missing evidence before effort is invested in a method the available records cannot support.
How to complete it
- Define Event / period and Contract question using actual time provisions and notice records. Identify Schedule references and test native logic, calendars, constraints and progress evidence.
- Explain Affected path and Method / limitation. Trace causation using the chronology, assess Competing causes and identify evidenced mitigation without preselecting a favourable time result.
- Record Checked time effect only after analysis and Reviewer challenge. Reconcile exhibits and limitations for submission, keeping time relief separate from compensable cost questions.
Who prepares and reviews it
A delay analyst or planner prepares it with contract, site and records specialists. An independent schedule reviewer challenges the method; qualified legal advisers address entitlement, while contractual determinations remain with the authorized decision maker.
A mistake to avoid
Assuming the duration of a late-information event equals the extension required overlooks float, actual progress, competing delays and the relevant completion obligation.
Illustrative example
Illustrative example: a project alleges delayed equipment information affected commissioning. The brief identifies relevant schedules, information dates and alternative delays to system completion. A specialist reviews the data before choosing an analysis method and determining whether the evidence supports a measurable effect on the contractual completion obligation.
