under a construction contract becomes due and payable—
(a) on
the date on which the payment becomes due and payable in accordance with the

the date occurring 15 business days after a payment claim is made under
Part 3 in relation to the payment.
(2) Interest is
payable on the unpaid amount of a progress payment that has become due and
payable at the rate—
(a)
prescribed under the Supreme Court Act 1935 in respect of judgment debts
of the Supreme Court; or
(b)
specified under the construction contract,
whichever is the greater.

by the claimant for use in connection with the carrying out of the
construction work for the respondent.
