CostGrid supports construction cost planning, control, evidence management, reconciliation and reporting. It does not independently certify accounting, tax, legal, regulatory, engineering or audit compliance; validate contractor or supplier claims; guarantee project cost, savings, profitability or completion outcomes; or replace authorised professional judgment.

Depending on severity and recurrence, CostGrid may issue a warning, temporarily restrict an action, suspend access or terminate an account or organisation relationship under the final Terms.
