42.1 Payment Claims, Certificates, Calculations and Time for Payment
At the times for payment claims or upon completion of the stages of the work under the Contract stated in Annexure Part A and upon the issue of a Certificate of Practical Completion and within the time prescribed by Clause 42.5. the Contractor shall deliver to the Superintendent claims for payment supported by evidence of the amount due to the Contractor and such information as the Superintendent may reasonably require. Claims for payment shall include the value of work carried out by the Contractor in the performance of the Contract to that time together with all amounts then otherwise due to the Contractor arising out of the Contract.
If the time for any payment claim under the preceding paragraph falls due on a day which is Saturday, Sunday, Statutory or Public Holiday the Contractor shall submit the claim either on the day before or next following that date which itself is not a Saturday, Sunday, Statutory or Public Holiday.
If the Contractor submits a payment claim before the time for lodgement of that payment claim, such early lodgement shall not require the Superintendent to issue the payment certificate in respect of that payment claim earlier than would have been the case had the Contractor submitted the payment claim in accordance with the Contract.
Within 14 days of receipt of claim for payment, the Superintendent shall assess the claim and shall issue to the Principal and to the Contractor a payment certificate stating the amount of the payment which, in the Superintendent's opinion, is to be made by the Principal to the Contractor or by the Contractor to the Principal. The Superintendent shall set out in the certificate the calculations employed to arrive at the amount and, if the amount is more or less than that amount claimed by the Contractor, the reasons for the difference. The Superintendent shall also set out, as applicable, in any payment certificate issued pursuant to Clause 42, the allowances made for -
(a) the value of work carried out by the Contractor in the performance of the Contract to the date of the claim;
(b) amounts otherwise due from -
(i) the Principal and the Contractor; and
(ii) the Contractor to the Principal;
(c) amounts assessed under Clause 46.4 and not duly disputed;
(d) amounts paid previously under the Contract;
(e) amounts previously deducted for retention moneys pursuant to Annexure Part A; and
(f) retention moneys to be deducted pursuant to Annexure Part A,
arising out of the Contract resulting in the balance due to the Contractor or the Principal, as the case may be.
If the Contractor fails to make a claim for payment under this Clause 42.1, the Superintendent may nevertheless issue a payment certificate and the Principal or the Contractor, as the case may be, shall pay the amount so certified within 14 days of that Certificate.
Subject to the provision of the Contract, within 28 days of receipt by the Superintendent of a claim for payment or within 14 days of issue by the Superintendent of the Superintendent's payment certificate, whichever is earlier, and within 14 days of the issue of a Final Certificate, the Principal shall pay to the Contractor or the Contractor shall pay to the Principal, as the case may be, an amount not less than the amount shown in such certificate as due to the Contractor or to the Principal, as the case may be, or if not payment certificate has been issued, the Principal shall pay the amount of the Contractor's claim. A payment made pursuant to this Clause 42.1 shall not prejudice the right of either party to dispute under Clause 47 whether the amount so paid is the amount properly due and payable and on determination (whether under Clause 47 or as otherwise agreed) of the amount so properly due and payable, the Principal or the Contractor, as the case may be, shall be liable to pay the difference between the amount of such payment and the amount so properly due and payable.
Payment of moneys shall not be evidence of the value of work or an admission of liability or evidence that work has been executed satisfactorily but shall be payment on account only, except as provided under Clause 42.6.
