Construction Claims: How to Prepare a Winning Time & Cost Claim
Cause–effect narrative, contemporaneous records, delay analysis methods and cost substantiation — the anatomy of an approved claim.
Claims win or lose on three pillars: entitlement, causation, quantum. Miss one and the claim collapses.
Entitlement
Cite the exact contract clause that gives you the right to claim. No clause, no claim.
Causation
Prove the cause-effect chain with contemporaneous records — programmes, correspondence, minutes, site diaries.
Delay analysis method
Time Impact Analysis, Windows Analysis, or As-Planned vs As-Built — pick the method the contract or protocol requires and apply it consistently.
Quantum
Substantiate every cost line with source documents: timesheets, invoices, plant records. Round numbers destroy credibility.
