Construction claims guide

Loss and Expense Claim Guide

A loss and expense record is strongest when cause, period, cost category and supporting project evidence can be followed without guesswork. This is general workflow guidance, not legal advice; always check the signed contract.

Separate each cost event

Record the cause, dates, affected resources, responsible project record and the contractual position requiring professional review for each event.

Keep contemporaneous substantiation

Preserve labour allocation, plant records, invoices, site overheads, diaries, programmes, instructions and correspondence. Reconcile claimed values to the underlying ledger.

Make assumptions visible

State calculation methods, exclusions, allocation assumptions, mitigation and evidence gaps clearly so a commercial reviewer can challenge and approve the submission.

Turn the guidance into a controlled project record

ContractingClaims keeps sources, events, missing information, drafts and versions together for professional review.
