13.4.5  Abortive Costs

In cases where the Authority decides to withdraw a request for a change in Service (particularly following Stage 1 approval for large-value changes) and the Contractor has incurred significant third party costs, the Authority should agree to reimburse the Contractor for any such third party costs reasonably incurred and evidenced in developing proposals up to the time the change request was withdrawn provided that budgets for such costs have been agreed in advance.
