(i) On the last day of each month, the plaintiff shall deliver to the superintendent Fisher a claim for payment with supporting evidence.
(ii) Within 14 days of receipt of the claim, the superintendent shall issue to the parties a payment certificate which shall set out the superintendent's calculation as to amount, and if the amount certified is different to the claim, the reasons for the difference.
(iii) The superintendent shall allow in the certificate, inter alia, amounts due by the plaintiff to the defendant "arising out of or in
connection with the contract including but not limited to any
amount due or to be credited under any provision of the contract".
It is pertinent to observe that the provision gives the superintendent a very wide power to make adjustments.
(iv) 'Subject to the provisions of the contract' within 28 days of the
receipt by the superintendent of the claim or within 14 days of
the issue of the payment certificate, whichever is earlier, the
defendant 'shall pay to the plaintiff ... an amount not less than
the amount shown in the certificate as due to the contractor'.
