How to organise claims evidence.

Claims evidence is the dated project record used to establish what happened, when it happened, what notice or contractual mechanism applies, and what impact requires assessment. A clear evidence set helps project teams evaluate an issue before turning it into a narrative.

Build a chronology before drafting

Start with a single dated timeline. Record the event, the source document, the author or issuer, the notice position, the relevant programme update, and the next action. A chronology reveals missing records and prevents a narrative from being built around recollection alone.

Keep evidence traceable

Each material statement should be traceable to a record. Preserve the original file, its date, its location, and any extract used. Separate factual records from assumptions, calculations, and opinions so reviewers can test the reasoning without redoing the entire exercise.

Assess the contract and programme together

Notice, entitlement, causation, time impact, and cost are connected but distinct questions. The governing contract and facts determine what must be proved; programme evidence helps assess timing and impact. A tool or template cannot decide entitlement on its own.
