Factual background
2The appellant at the relevant time traded under the name Domus Homes. Part of its business activities apparently involved management of construction projects. On 15 October 2008, it entered into a contract with the respondent in respect of a factory development at Riverwood, New South Wales ("the agreement"). The agreement, described as "Domus Homes Steps Document", so far as relevant contained the following provisions:
" COMMERCIAL IN CONFIDENCE
The following is the outline of the 'Project Management Delivery' process for a $3,450,000 (target construction budget as outlined in 'Basis of the Bonus Arrangement' below, but excluding GST, survey plan, Council fees and contributions, Section 73 design and contributions, temporary water and power to site, geotechnical report and piering and/or piling with the reservation of the right to amend the proposal subject to Council DA conditions, final construction specifications and final geotechnical report), 4,870m2 industrial building project comprising 4,350m2, 9.0m high clear span warehouse plus 520m2 office space and driveways, parking and landscaping. The Domus Homes fee includes a fixed price project management service fee of $130,000 plus GST plus a bonus payment to be shared on a 50/50 basis between H. M. Australia Holdings Pty Ltd (HMAH) and Domus Homes for all savings affected below the $3,450,000 target mark (excluding the exclusions listed above and excluding GST). The bonus payment plus GST is to be made in full on occupation of the property or at the end of the main construction work, which ever occurs sooner.
The Basis of the Bonus Arrangement
The basis of the bonus arrangement is as follows:
Based on research carried our by both HMAH and Domus Homes, the parties believe that a target budget of $3,450,000 for the project is achievable. Based on input from the builder recommended by Domus Hones, it may be possible to achieve a lower budget than the target budget, as outlined below. Should the project be delivered for an amount lower than the target budget, this saving will be shared on a 50/50 basis between HMAH and Domus Homes
The structure will not be a design and construct model which we believe assumes too much risk and gives too much profit, but one where HMAH controls the design and delivery process through Domus Homes where HMAH pays for its consultants directly at significantly reduced risk. The proposed financial model is as follows:
Costs to HMAH (excluding GST):
Project Management $130,000
Architect (3.0%) $88,000
Other consultants $35,000
Construction estimate $2,922,000 ($600/m2)
Total Possible Cost
(excluding exclusions) $3,175,000
Base line target budget $3,450,000
Difference to be shared 50/50 $275,000
Bonus to Domus Homes 50%
excluding GST (estimated) $137,500
Share to HMAH 50% excluding
GST (estimated) $137,500
The 'Cost to HMAH if savings target met' of $3,4500,000 is NOT a guaranteed maximum price. It is however a realistic target price based on input from relevant parties with whom we have had discussions. The above figures are by way of an example only and the actual figures will vary expect for the Base Line Target Budget (BLTB). If the project is not brought in below the BLTB, then no bonus payment will be made to Domus Homes. Any savings below the BLTB of $3,450,000 will be paid out at 50% to Domus Homes in full as a bonus, irrespective of what that figure is plus GST excluding the exclusions listed above plus office and warehouse fitout like storage racks, furniture and partitions.
The above cannot be construed as a guarantee. The above is indicative only, based on research carried out by Domus Homes as well as HMAH to deliver HMAH the safest and most economical result in good faith.

Step 2: Design Meeting
On Survey, geotechnical report and Architectural Brief completion by the client, David Edelstein, the architect and the project principal/s (client) meet to finalise the Architectural Brief. The architect is paid directly by the client, but coordinated by Domus Homes.
...
Step 6: Council Submission
The plans are submitted to council after a payment to Domus Homes of $21,666.67 plus GST by the client. This payment covers the management and coordination of the Development Application including all representations and meetings with Council as required. The additional consultants if required for the application (including planner, hydraulics engineer, traffic engineer, landscape designer, geotechnical engineer and/or geotechnical investigation, BASIX and Section J specialist etc) are co-ordinated by Domus Homes, but are paid for by the client as are applications fees and statutory charges. In the event of Council or the client requiring post submission changes where extra work is required (excluding minor changes), Domus Homes' rate of $250/hr plus GST will apply and Domus Homes will negotiate fees for the work with the architect and other consultants, if required, for client approval.
...
Step 11: Construction Management and Delivery
As construction progresses, Progress Payments are made by the client to the builder as stipulated in the construction contract: Domus Homes is also paid $21,666.67 plus GST in advance of the construction programme by the client, for its role as the client's representative in managing the consultants and contractor to deliver the project in accordance with the terms of the contract. Domus Homes will conduct regular site meetings and inspections to monitor and administer the works.
Step 12: Occupation and Completion
As the project nears completion, final inspections take place for occupation. Once the building is suitable for occupation, the client can move into the property. An Occupation Certificate is also prepared and issued by the Certifier. On occupation and/or building completion, a reconciliation is done and the bonus to Domus Homes gets settled in full within 7 days of invoice, failing which interest at 10.0% pa will apply for outstanding payments. Urgent defects, should they occur, will be repaired immediately by the builder, whilst smaller defects will be repaired at the end of the maintenance period. Domus Homes will co-ordinate this work. Hereafter, a Final Certificate is issued where all final payments are made to the builder.
Conditions
...
All payments are claimed under the Building and Construction Industry Security of Payment Act of 1999 NSW Section 13.
...
All instructions to builders, subcontractors and consultants may only be carried out through Domus Homes. No variations will be carried out unless they are in writing with fully agreed scope, price and sign off by the client. Payments are required within 7 days of invoice (Bonus payment only - all other stages paid in advance) after which an interest rate of 10.0% pa will apply."
It should be noted that the Mr Edelstein referred to in Step 2 was a Director of the appellant.
3The agreement was executed on behalf of the respondent by Mr Hui Ouyang (also known as Mr Harvey Ouyang) and a Ms Yeung Lo (also known as Ms Maggie Lo). They were described as owners.
4On 26 November 2010, Mr Edelstein sent an email to Mr Ouyang in the following terms:
"Hi Harvey, Riverwood Bonus claim attached for your attention ASAP please. Thank you for your instructions on this project. Regards."
5The email attached two letters from the appellant to the respondent. The first stated as follows:
"Dear Harvey & Maggie,
LOT 1, DP264375 JINDALEE PLACE, RIVERWOOD NSW 2210.
BONUS
ABN: 34 099 585 476
Under the terms of our agreement (the Domus Homes Steps Document, ie. 'DHSH') signed and dated 15 October 2008 by David Edelstein of Domus Homes and Yeung Lo and Hui Ouyang of H. M. Australia Holdings Pty Ltd, I am acting on my rights to amend the final proposal in the DHSD based on the terms therein which entitles the final Bonus figure to be adjusted.
A work sheet is attached outlining the Bonus workings for your assistance. A tax invoice is also attached for your immediate attention.
As the subject building has now been occupied and the end of the main construction work has been completed, the Bonus is now due under the terms of the DHSD agreement.
Thank you for your instructions on this project and I look forward to a continuing working relationship with you."
6The second invoice was described as a tax invoice. It was directed to the respondent and made a claim for a bonus in the following terms:
"Dear Harvey & Maggie,
LOT 1, DP264376 JINDALEE PLACE, RIVERWOOD NSW 2210.
BONUS
ABN: 34 099 585 476
As the subject building has now been occupied and the end of the main construction work has been completed, the Bonus is now due under the terms of our 'Domus Homes Steps Document' agreement between David Edelstein of Domus Hones and Yeung Lo and Hui Ouyang of H. M. Australia Holdings Pty Ltd dated 15 October, 2008.
The terms of our agreement were that we would be paid as a bonus of 50% of any savings under the Base Line Target Budget (BLTB). Please find attached our working sheet showing how the variations requested by you during the project affected the BLTB and setting out the bonus now due and payable to Domus Homes.
As per the attached work sheets, the Bonus amount now due to Domus Homes is $195,376.00 plus $19, 537.60 GST being, $214,913.60.
Thank you for your instructions on this project.
Any recommendations of our services to your family, friends and associates will always be greatly appreciated.

7The worksheet referred to in the letter described as a tax invoice set out the base line target budget of $3,450,000 and added to that figure an amount of $806,725 in respect of variations agreed to during the course of construction. As the actual costs of construction was $390,752 below the amount so calculated, the respondent claimed a bonus of 50% of that amount plus GST totalling the figure of $214,913.60.
8On 2 December 2010, a Mr Patrick Wang who described himself as an assistant accountant send Mr Edelstein an email requesting the spreadsheet of the appellant's bonus calculation in Excel format. That was supplied on the same day. On 6 December 2010, Mr Wang sent an email to Mr Edelstein in the following terms:
"Thanks for your spreadsheet.
I have discussed the calculation with Harvey, he has made some adjust [sic] to the sheet, please see attached file. The yellow highlighted ones are basic infrastructures of the building which Harvey believes should not be exclusions. The red highlighted figures are adjusted by me because of the differences with the invoices we have received."
9A spreadsheet with the adjustments was attached. That showed a bonus paid to the appellant of $21,811.
10On 13 December 2010, Ms Lo emailed Mr Edelstein requesting a meeting to discuss the bonus payment on 14 December. She stated that she would have Harvey, Girish (GM) and Patrick (Accounts) present as well. It can be inferred that Patrick was Mr Wang.
11On 22 December Mr Edelstein sent an email to Ms Lo, copy to Mr Ouyang, headed "Adjudication Application of Payment Claim under the Security of Payments Act 1999". The email provided as follows.
"On 26 November 2010 I sent you a payment claim under the Building and Construction Industry Security of Payment Act.
You have not responded with a payment schedule.
The letter now serves as formal notice that I intend to apply for adjudication of my payment claim. This correspondence offers you an opportunity to provide a payment schedule, which should be provided within 5 business days. I remind you that, pursuant to s 14 of the Act, the payment schedule must indicate the amount of the payment that you propose to make and, where the amount is less than the amount claimed (being $214,913.60), indicate why you propose to make a lower payment."
12Ms Lo responded to the email on the same day. Her response was to the following effect:
"The agreement that you refer to was signed on the 15 th of October 2008. This agreement was based on a plan (refer attached) that never eventuated.
The building that was constructed was based on a different plan with dissimilar dimensions.
We have tried to discuss with you to resolve the issues. We have requested that each item of the agreement be revisited to establish the validity of the items.
So far you have not been willing to engage in discussions at that level.
Our doors are open to any discussions that you may with to have with us."
13On 19 January 2011, the appellant made an adjudication application and served it on the respondent. The application was withdrawn on 7 February and the appellant thereafter made a new adjudication application. That was served on the respondent on 9 February 2011. A Mr Davenport accepted the adjudication and determined that the adjudicated amount was $214,913.60 inclusive of GST.
14It should be noted that on 28 January 2011 the respondent purported to make a response to the appellant's adjudication application pursuant s 20(1) of the Act. These submissions were based on the premise that a payment schedule complying with s 14 of the Act had been served by the respondent. The respondent now concedes that no such payment schedule was served. However, in the respondent's submissions to the adjudicator the following remarks were made:
"8. On or about 26 November 2010, the Claimant made a payment claim for the bonus it alleges is payable pursuant to the Agreement. It is this payment claim that is the subject of the instant Adjudication Application.
...
12. On or about 6 December 2010 the Respondent, by its servant Patrick Wang, served a payment schedule upon the claimant pursuant to ss.14(1).
...
19. Progress payment is defined in section 4 of the Act to include:
a. The final payment for construction work carried out ... under a construction contract, or
b. A single or one-off payment for carrying out construction work ... under a construction contract, or
c. A payment that is based on an event or date (known in the building and construction industry as a milestone payment.)
20. It is submitted that the instant claim is not a progress claim, rather it is a claim for a bonus that was contingent upon the completion of the construction work and directly referable to savings brought about by the claimant. The quantum of which could only be determined upon completion of the job.
21. Even if, however, the claim is held to be a progress claim, the due date for the payment of that claim would have been 7 December 2010. As the Contract provides that the bonus payment is required within 7 days of invoice. As the claim was made on 26 November 2010, the 7 th day after 26 November 2010 was 7 December 2010.
22. On 6 December 2010 the respondent, by its servant Patrick Wang, served a payment schedule upon the claimant in compliance with the requirements in section 14(1) of the Act. The Respondent submits that;
a. The email complies with s.14(2)(a) (in identifying the payment claim) because it refers to the claimant's excel spreadsheet which contains the calculation by which the payment claim was derived. That excel spreadsheet was also attached to the payment claim - and so, a reference to the spreadsheet is, by implication, a reference to the payment claim.
b. Equally, the email complies with s14(2)(b) (in indicating the amount proposed to be paid) because it provided sufficient information for the claimant to know the respondent's position by stating which items the respondent believed should not be exclusions. The respondent submits that paragraph 14 of the claimant's submissions supports this contention.
c. The respondent notes that no amount has been paid to date on account of the claimant's refusal to accept the respondent's proposed payment."
The submission was signed by Mr Ouyang.
