The adjudicator's determination
4 The appellant served its payment claim on 3 June 2005. It claimed $180,808.17 less $53,401.50 already received, a balance of $127,406.67, all plus GST. The contract had been earlier terminated by the respondent, prior to completion of the works. The claim had the four components of contract work, variations, "interest due to delayed payments … from termination date of 31/03/05 …", and "loss of margin due to wrongful termination".
5 As to contract work, the contract provided that claims "must relate to the contract price", and must identify and relate to the work done by the appellant and properly value the work "with reference to the contract price" (cll 10(a), (c)). The payment claim identified, for each of a number of elements of the works, the contract sum attributable to that element, the percentage claimed to have been completed to date and the amount claimed. In several instances the amount claimed did not mathematically reflect the percentage of the contract sum attributable to the relevant element.
6 The contract provided that payments were to be made to the appellant "on the date determined by reference to the Schedule Point D" (cl 11(a)), by which claims were to be made by the appellant on the 30th of each month and were to be paid "within 30 days of claim"; but also that if a payment claim was submitted after the 30th of a month, payment was postponed to the next payment period (cl 10(f)). The contract also provided for ten per cent retention to a maximum of five per cent of the total amount payable to the appellant (cl 13). The payment claim did not specifically refer to these provisions, although it stated that "release of retention" was included in the claimed components of contract work and variations.
7 The respondent served its payment schedule on 21 June 2005. The payment schedule included, as one of the reasons for withholding payment, that the claim had been made on the basis of percentages of the contract sum but that the amounts claimed did not reflect the percentages claimed by the appellant to have been completed. It set out different, and sometimes lesser, percentages completed which the respondent was prepared to allow, and the value of the completed work on that basis. It deducted from the total amount allowed "contra charges", including for liquidated damages and rectification work, and the retention sum from previous progress payments. The result, according to the payment schedule, was that the appellant owed the respondent $83,265.50.
8 The payment schedule also did not specifically refer to the contractual provisions concerning the date of payment and retention, although it clearly recognised a retentions regime.
9 The appellant made the adjudication application on 27 June 2005. The adjudicator accepted referral of the adjudication on 1 July 2005.
10 The respondent's adjudication response, served on 5 July 2005, relied on an assessment by Mr Dann and a report of Enginuity as to the value of the completed work. The respondent's submissions included in the adjudication response also raised two so-called jurisdictional issues, namely -
· that there was no construction contract between the parties because in the contract the proprietor was named "Homewood" not "Holmwood"; and
· that the payment claim was not validly served because it was served by the appellant's solicitor and not by the appellant personally.
11 The submissions included in the adjudication application and the adjudication response did not specifically refer to the provisions concerning the date of payment and retention.
12 The adjudicator's determination was dated 7 July 2005 and issued on 29 July 2005. He determined that the respondent should pay $116,598.35 to the appellant, that the date upon which the payment became due was 21 June 2005 and that the rate of interest was the rate payable on unpaid judgments of the Supreme Court.
13 The adjudicator said as to the two jurisdictional issues, and it was not submitted in this Court that he was in error in the lack of merit he saw in them -
"The respondent claims that there is no construction contract between the parties. The respondent points to the fact that the written contract states, 'Name of Principal - Homewood Holdings P/L' whereas the respondent is Holmwood Holdings Pty Ltd. The respondent says that 'the Claimant is now estopped from contending that the contract contained an error in the principle's (sic) name'. The respondent has not contended that there is any company called 'Homewood Holdings P/L' or that the contract was intended to be with anyone other than the respondent. The respondent has not disputed that the construction work was carried out by the claimant for the respondent.
The copy of the written contract produced by the claimant is dated 16/9/04 and appears to be signed by both parties. The copy produced by the respondent is dated 24/11/04 and appears to be signed only by the respondent. Otherwise the copies appear to be the same. The contract is between Tricon Projects Pty Ltd and the claimant. Tricon is the 'Construction Manager'. The contract states, 'The Construction Manager is the disclosed agent of ('The Principal'). The contract appears to have been prepared by Tricon, signed by Tricon for the Principal and sent by Tricon on 20/9/04 to the claimant for signature.
I have no doubt that there was a construction contract between the claimant and Tricon's principal. The respondent has submitted a copy of the construction management contract between the respondent and Tricon appointing Tricon as construction manager. The respondent has not denied that Tricon was the respondent's agent and that as agent of the respondent, Tricon contracted with the claimant for the carrying out of the construction work the subject of this adjudication application. There is no suggestion that there was a company with the name 'Homewood Holdings P/L'. The respondent has produced nothing to show that the respondent was not a party to a construction contract with the claimant. The mere fact that the name of the respondent was not correctly spelt on the written contract prepared by Tricon is no bar to the claimant making this payment claim. The respondent has produced nothing to show that there is any estoppel. This 'defence' is totally lacking in merit and the fact that the respondent raises it reflects upon the credit to be given to the respondent's other contentions.
The respondent contends that the payment claim does not comply with the requirements of section 13(1) of the Act. The respondent contends that service of the payment claim on the respondent bv the claimant's solicitor is a 'fatal matter'. This is nonsense. A claimant can use an agent to serve the claimant's payment claim. The payment claim is clearly the claimant's document. Section 13(1) has been complied with."
14 When he came to the value of the completed work, the adjudicator said -
"The claimant assesses the value of work completed at $152,000. The respondent assesses the value at $59,376 before deducting 'contra charges' of $90,707. I am faced with two quite different assessments of the value of work carried out. The respondent relies upon the assessment of Mr Dunn [para 26 and following of his statutory declaration]. Mr Dunn says that the report of Enginuity has been prepared to provide an assessment of the value of work completed. I find that report of no assistance. It is based upon the assessment of Yorkshire Electrical Services [dated 13/6/05] of outstanding work and remedial work allegedly required. That assessment is merely Yorkshire Electrical's 'approximate breakdown of hours spent on rectification of works'. I don't consider that the time allegedly spent by Yorkshire Electrical on 'rectification works' is a valid method of assessing the value of work carried out by the claimant.
The report of Enginuity is also said to be based upon an assessment of the payment claim by Tricon Projects dated 14/6/2005. This appears to be the assessment of Mr Dann. It seems to me that the report of Enginuity cannot be said to be an independent assessment of the value of work carried out by the claimant. In assessing the value of work completed, I have the assessment by the parties but I do not have evidence upon which I could independently arrive at a value.
In deciding whether to adopt the assessment of the claimant or that of the respondent I am mindful of the respondent's unmeritorious challenges to the validity of the payment claim [the allegation that the respondent was not a party to the construction contract and that service by an agent is not valid service] and the respondent's completely unjustified deduction of alleged liquidated damages of $89,100. In the light of these matters, I am more inclined to believe the claimant rather than the respondent and I will adopt the claimant's valuation of $152,000 in preference to the respondent's valuation of $59,376 for the value of completed work before adding the amount for variations."
15 The adjudicator continued -
"The claimant has assessed variations at an additional $7,635. The respondent has assessed the claimant's entitlement with respect to variations at $7,400. The difference [$235] is in respect of an item 'Installation of conduit for lift supply'. Mr Dann in his statutory declaration [para 53] says that this work is contractual work and is therefore not a variation. In the submission accompanying the adjudication application the claimant makes no reference to this item. The claimant has failed to satisfy me that the claimant is entitled to this $235. Therefore, in calculating the amount of the progress payment I will include the agreed amount of $7,400 for variations but not the disputed amount of $235.
Adding the value of work completed $152,000 (before adding variations) and the value of variations $7,400. I calculate the total value of work completed by the claimant at $159,400 plus GST. When I deduct the amount paid, I arrive at the amount of $105,998.50. For reasons following, this plus GST [a total of $116,598.35] is the amount of the progress claim to which the claimant is entitled."
16 The adjudicator declined to allow the claimed amounts for interest and loss of profit; it is not necessary to go to his reasons for doing so. He rejected some other matters on which the respondent relied to withhold payment. He then said -
" Due date for payment
Neither party has made a submission as to the due date for payment of the progress payment. Therefore, applying s 11(1)(b) of the Act, I determine that it is 10 business days after the payment claim was served. Since there is a dispute over the date of service, I will, for the purpose of calculating interest, treat it as 6 June 2005. That makes the due date for payment 21 June 2005."
The trial judge's decision
17 The trial judge directed himself in accordance with the decision of this Court in Brodyn Pty Ltd v Davenport (2004) 61 NSWLR 421, relevantly that an adjudicator's determination will be void if there was not compliance with "basic and essential requirements" laid down by the Act and a bona fide attempt by the adjudicator to exercise the statutory power (see Brodyn Pty Ltd v Davenport at [53]-[56]).
18 His Honour noted the respondent's submission that the adjudicator failed to consider the provisions of the construction contract (see s 22(2)(b) of the Act) and that in determining an adjudication application the adjudicator "is to consider the following matters only … (b) the provisions of the construction contract from which the application arose". He concluded that such a failure "is jurisdictional error, resulting in invalidity of the determination" (at [51]). He discussed this in some detail, with reference also to the subsequent decisions of this Court in Minister for Commerce v Contrax Plumbing (NSW) Pty Ltd [2005] NSWCA 142, Co-ordinated Construction Co Pty Ltd v J M Hargreaves (NSW) Pty Ltd (2005) 63 NSWLR 385 and Co-ordinated Construction Co Pty Ltd v Climatech (Canberra) Pty Ltd [2005] NSWCA 229, when failure to pay regard to a provision of the contract relevant to the adjudication constituted non-compliance with a basic and essential requirement of the Act.
19 From the absence of reference to the contractual provisions concerning the date of payment, while arriving at a due date for payment applying s 11(1)(b) of the Act (which applies "if the contract makes no express provision with respect to the matter"), and from the absence of consideration of retentions already deducted and inclusion of retained sums in the amount to be paid by the respondent, the trial judge considered that there had not been "mere error in consideration of the provisions of the contract, but a failure to consider a relevant provision at all" (at [57], [60]). Thus he concluded -
"61 It follows that in my opinion the adjudicator failed to have regard to relevant provisions of the construction contract, and in particular clause 10, Part D of the Schedule, and clause 13(a). This was not a mere error of fact or law in determining whether or not particular provisions were provisions of the construction contract, or in the interpretation and/or application of those provisions, but a complete failure to have regard to them at all, in circumstances where those provisions were relevant to the adjudication under consideration.
