Section 5Payment

Clause 53.4

Final Amount Due and Conclusivity

Purpose

The assessment of the final amount due is changed to include any agreement the Parties reach and a decision of the Adjudicator or recommendation of the Dispute Avoidance Board which has not been referred to the tribunal within four weeks. A changed assessment becomes conclusive evidence of the final amount due.

Practical Application

The final amount due incorporates agreed settlements and any adjudicator decisions that are not challenged within four weeks. Once conclusive, neither Party can reopen the final account.

Common Pitfalls

The four-week window for challenging an adjudicator's decision before it becomes conclusive is critical. Any Party dissatisfied must refer the matter to tribunal within this period or lose the right.
