Decision
23The starting point is the obligation of the proprietor to pay the price of the building works in accordance with cl 3.1. That obligation is to pay the price in the way, and at the times, stated in cl 13, read in conjunction with sch 4.
24The subject of cl 13 is, in terms, progress payments. What it establishes is a regime for payment of the amount due under the contract, for the building works, by instalments. It is, in substance, a regime for liquidation of the balance of the price from time to time, by instalments.
25Unless it can be said that cl 13 provides a condition precedent to any entitlement to be paid the entire price, the proprietor's defence is not sustainable. That analysis seems to me to focus attention on the role that cl 13 pays in the scheme of the contract as a whole.
26It is not cl 13 that imposes the obligation to pay, and gives the entitlement to be paid. That function is served by cl 3.1. What cl 13 does is provide an entitlement to, and a mechanism or instalment pattern for, progress payments.
27Progress payments seem to me to have benefits for both parties to a building contract. From the builder's perspective, they serve the vital function of providing cash flow (the importance of which is recognised, although not in a manner relevant to the issues in these proceedings, by the Building and Construction Industry Security of Payment Act 1999 (NSW).
28From the proprietor's perspective, provisions such as cl 13 provide an opportunity to pay the cost of the works by instalments, accompanied by an opportunity to assess the amount of each instalment as it is claimed.
29But to go further, and to say that a mechanism as to how payments are to be claimed and made has the further function of conditioning, precedentially, the entitlement to payment of the price as a whole seems to me to be putting far too high a burden on cl 13, either read on its own or in the context of the contract as a whole.
30It may be accepted that a failure to comply with the requirements of cl 13 would provide a proprietor with a defence to a claim for a particular progress payment. Thus, if the builder had taken the opportunity to sue for one or more of the unpaid progress claims that it rendered, the proprietor could have raised, by way of defence, failure to comply with (for example) cll 13.1 and 13.5. If, factually, those defences were made good, then the entitlement to the progress claim would be defeated.
31But it does not seem to me that this analysis applies when the claim is brought for the balance of the price, in circumstances where the works have been completed and where the unpaid cost of the works and the cost of rectification of defects have both been assessed. If it were otherwise, it would be necessary for the builder to resubmit (as already it has done) all the invoices, together with all their supporting documentation, and the insurance certificate. In circumstances where that would do no more than give an opportunity, which is now meaningless, to analyse the amount of the claim, it does not seem to me that the Court should construe clause 13, so as to impose that as an obligation to be satisfied before the now defined balance due is paid, unless the language is intractable. And for the reasons I have given, I do not think that it is.
32Thus, as a matter of construction of the contract, I do not think that the defence is made good.
33There are two other answers to this aspect of the defence. The first is that, functionally, the requirements of cl 13 have been satisfied. That has been achieved through the correspondence to which I have referred earlier in these reasons. Thus, if (contrary to my view) it were necessary for the documents to be supplied before there were any entitlement to be paid, those documents have been supplied.
34The alternative approach is that, the builder having done all the work and the cost thereof and the offset in cost of defects rectification having been agreed, the builder has a claim on a quantum meruit basis. But since, as I have said, I think that the contractual claim is made good, it is not necessary to go any further.
