(2) In this section, reference date , in relation to a construction contract, means:
(a) a date determined by or in accordance with the terms of the contract as the date on which a claim for a progress payment may be made in relation to work carried out or undertaken to be carried out (or related goods and services supplied or undertaken to be supplied) under the contract, or
(b) if the contract makes no express provision with respect to the matter - the last day of the named month in which the construction work was first carried out (or the related goods and services were first supplied) under the contract and the last day of each subsequent named month."
16 This section creates an entitlement to a progress payment by reference to a specified date but does not attempt to quantify the amount of the payment. That task is left to s.9:
" Amount of progress payment
The amount of a progress payment to which a person is entitled in respect of a construction contract is to be:
(a) the amount calculated in accordance with the terms of the contract, or
(b) if the contract makes no express provision with respect to the matter, the amount calculated on the basis of the value of construction work carried out or undertaken to be carried out by the person (or of related goods and services supplied or undertaken to be supplied by the person) under the contract."
17 Section 10(1) is also relevant:
" Valuation of construction work and related goods and services
(1) Construction work carried out or undertaken to be carried out under a construction contract is to be valued:
(a) in accordance with the terms of the contract, or
(b) if the contract makes no express provision with respect to the matter, having regard to:
(i) the contract price for the work, and
(ii) any other rates or prices set out in the contract, and
(iii) any variation agreed to by the parties to the contract by which the contract price, or any other rate or price set out in the contract, is to be adjusted by a specific amount, and
(iv) if any of the work is defective, the estimated cost of rectifying the defect."
18 The first step in applying s.8 is to identify the "reference date". Section 8(2) envisages two alternative and, it appears, mutually exclusive possibilities, namely, that the parties' contract contains terms in accordance with which there is to be determined "the date on which a claim for a progress payment may be made in relation to work carried out or undertaken to be carried out … under the contract" (s.8(2)(a)); or that "the contract makes no express provision with respect to that matter" (s.8(2)(b)). Given the word "express" in s.8(2)(b), it must be the case that the terms envisaged by s.8(2)(a) are confined to express terms.
19 The question posed by s.8(2)(a) is accordingly whether the express terms of the contract provide for the determination of the date on which there may be made a claim for a "progress payment", such claim for a "progress payment" being "in relation to work carried out or undertaken to be carried out … under the contract". If the s.4 definition of "progress payment" is applied, the question becomes whether the express contractual terms make provision for the determination of the date on which a claim may be made for "a payment to which a person is entitled under section 8", including a payment of the particular kind covered by paragraph (a), (b) or (c) of the definition to which an entitlement arises under s.8. As a matter of strict construction, an express contractual term could be regarded as making provision for the determination of the date on which a claim might be made for a payment the entitlement to which arises under s.8 of the Building and Construction Industry Security of Payment Act only if the contractual term referred to that Act, that section and the entitlement created by the section. If, in the ordinary way, the contract provided for periodic assessment of the quantity or value of work done and, without in any way referring to the Act or s.8, created in the party who had done the work a contractual entitlement to claim on some specified date a payment related to that work, the situation would not be one in which, in terms of s.8(2), the express terms of the contract provided for determining a date on which a claim for what the Act calls a "progress payment" might be made. The absence of any reference to the Act and s.8 would mean that the periodic payments provided for in the contract were not "progress payments" as defined by s.4. The entitlement to those payments would be sourced in the contract, not in s.8 of the Act.
20 A similar analysis applies to s.9. If the contract makes no express provision with respect to "the matter" (being, clearly enough, the matter of "the amount of a progress payment to which a person is entitled in respect of a construction contract"), the amount to which the s.8 entitlement extends is to be calculated under s.9(b). If, on the other hand, there is such an express provision in the contract, the amount to which the s.8 entitlement relates is "the amount calculated in accordance with the terms of the contract" as specified in s.9(a). Again, application of the s.4 definition of "progress payment" would mean that s.9(a) applied only if the contract made express provision for the calculation of the amount to which an entitlement under s.8 of the Building and Construction Industry Security of Payment Act related and would not apply where the contract merely created a progress payment regime in the way commonly encountered in the construction industry.
21 Parliament cannot have intended that ss.8 and 9 should operate in such a way that, if contractual provisions of the ordinary kind creating a progress payment regime do not refer to entitlements under s.8 of the Building and Construction Industry Security of Payment Act, the statutory entitlements under ss.8 and 9 are to be geared to the monthly timing schedule in s.8(2)(b) and the method of quantification in s.9(b). Having regard to the objects of the Act stated in s.3, it must be accepted that there was an intention that the statutory mechanisms should underwrite the contractual system of progress payments where the parties had adopted one. Such parties were not meant to be denied their agreed system and forced on to the timing and quantification in ss.8(2)(b) and 9(b) just because the express terms of their contract did not adopt the statutory definition of "progress payment". It must follow that ss.8 and 9 (and, as to actual calculation, s.10) are to be approached on the footing that where there is an express contractual regime for the claiming and making of progress payments in the ordinary sense, divorced from the defined meaning arising from s.4, the matters of timing and quantification with which ss.8 and 9 are concerned are to be determined in accordance with the express contractual provisions on the subject. This is the approach that commended itself to McDougall J in Musico v Davenport (above). It involves the conclusion that, to the extent that the expression "progress payment" plays a part in deciding whether ss.8(2)(a) and 9(a) apply, the context is, as contemplated by s.6 of the Interpretation Act, one indicating a meaning other than that derived from the s.4 definition.
22 Before leaving this examination of the statutory provisions, I should refer to the aspects of the s.4 definition of "progress payment" covered by paragraphs (a), (b) and (c). As I have said, the part of the definition that begins "and includes" and contains paragraphs (a), (b) and (c) was added by the amending Act of 2002. Although the concept of entitlement under s.8 is not expressly mentioned in the part of the definition beginning with the words "and includes", I am of the opinion that, by clear implication, an item within paragraph (a), (b) or (c) is intended to be a "progress payment" for the purposes of the Act only if it is something to which an entitlement arises under s.8. This reading ensures that a payment of the particular kind has the characteristic that gives any other payment the quality of "progress payment" for the purposes of the Act. The reading is also consistent with the legislative intent reflected in both the Explanatory Notes to the Bill that became the Building and Construction Industry Security of Payment Amendment Act 2002 and the Second Reading speech of the Minister for Public Works and Services. The Explanatory Notes include the following:
" Schedule 1[7] amends the definition of progress payment to make it clear that the Act creates an entitlement not only to payments that are in the nature of instalments, but also to final payments and to single one-off payments."
23 The Second Reading speech (Legislative Assembly, 12 November 2002) contains the following passage:
"Minor changes have been made to remove possible ambiguities, for example, to ensure that progress payments include milestone payments, that progress claims under the Act can be made under construction contracts that have no provision for progress payments, and that progress claims can include the final amount claimed and retention moneys."
24 One purpose of the amendments was, clearly enough, to overcome the decision in Jemzone Pty Ltd v Trytan Pty Ltd (2002) 42 ACSR 42 that, for the purposes of the Act, a distinction is to be drawn between part payment while work is in progress and final payment upon or after its completion.
25 Against this background, I return to the circumstances of this case. The contract, as found by the adjudicator, was a lump sum contract which briefly described the work to be done and provided for an overall and undissected price of $320,000. There were no contractual provisions with respect to progress payments according to the ordinary understanding of the concept. The parties, by their conduct, may be taken to have superimposed some progress payment regime in a practical sense since it is clear that some payments were made and accepted during the course of such of the work as was actually done. The contractor (first defendant) left the site before the specified work was completed and the contract came to an end in a way on which the adjudicator made no firm findings. The rights and wrongs of that do not matter. The significant point is that the totality of the work for which the contract provided had not been performed when the contract came to an end.
26 The adjudicator, as has been seen, purported to treat as a progress payment under the Act the whole of the unpaid balance of the lump sum contract price, adjusted for agreed minor items. The first defendant submits that, in approaching the matter in that way, the adjudicator proceeded consistently with the Act, the unpaid balance of the lump sum price, as adjusted, being "the final payment for construction work carried out … under a construction contract" and thus within paragraph (a) of the definition of "progress payment". The plaintiff submits that that characterisation is incorrect and that the adjudicator did not, as required by s.22, determine the amount of any "progress payment" at all and hence did not embark upon or perform the task set for him by the Act.
27 In my judgment, the submission made on behalf of the plaintiff is correct. Paragraph (a) of the definition of "progress payment" not only refers to a "final payment", it also refers to that payment being "for construction work carried out … under a construction contract". The focus is thus upon work actually done. Once that work is identified, it is necessary to see that the payment in question is a payment "for" that work. The payment must accordingly be found to have the character of remuneration or reward referable to the doing of the work. If, as in the present case, particular work is specified as the totality of the contracted work and a particular sum is provided for as the remuneration or reward referable to the totality of the contracted work, but only part of the contracted work is done, the whole of that sum (or so much of it as has not already become payable) simply cannot represent a sum payable "for" the part of the work actually done.
28 I might add, by way of aside, that I do not consider that the whole payment for the totality of work under a lump sum and entire contract could sensibly be regarded as within paragraph (a) of the definition of "progress payment". A "final payment", being "final", comes after some earlier payment or, at least, after a liability to make some earlier payment has arisen.
29 The conclusion that the s.4 definition did not catch the whole of the contracted sum (or so much of it as has not already become payable) in the case of a lump sum contract where only part of the work had been done would, in my opinion, be reached if the first defendant sought to rely upon the "means" part of the s.4 definition of "progress payment" instead of paragraph (a) of the "and includes" part. In the absence of that paragraph, a final payment of the present kind may well not be within the "progress payment" definition but, even if that obstacle did not exist, I am satisfied that, in the context of the Act as a whole, "progress payment" imports a notion of part payment (including final payment) referable to or on account of actual work. Relevant indications are found in s.3(1), the definition of "claimed amount" in s.4 and s.13(2), as well as ss.8, 9 and 10 themselves.
30 Section 3(1) is as follows:
"The object of this Act is to ensure that any person who undertakes to carry out construction work (or who undertakes to supply related goods and services) under a construction contract is entitled to receive, and is able to recover, progress payments in relation to the carrying out of that work and the supplying of those goods and services."
