Breakdown of Claim in NSW Payment Claims
⚠️ Compliance Warning
Failure to provide an adequate breakdown of your claim is a primary cause of payment disputes and can lead to your payment claim being declared invalid under the Act.
1. Field Name and Definition
The Breakdown of Claim is an itemised calculation that comprehensively shows how the total claimed amount in your payment claim was determined. This critical field serves as the mathematical foundation of your payment claim, providing a transparent and detailed calculation of all work completed, materials supplied, and variations claimed during the payment period.
This field appears on every payment claim because it fulfils the fundamental requirement of demonstrating the basis of your claim. It transforms your claimed amount from a mere number into a substantiated calculation that can be verified, understood, and assessed by the respondent and, if necessary, an adjudicator.
2. Legal Requirements
Statutory Requirements
Under section 13(2)(a) of the Building and Construction Industry Security of Payment Act 1999 (NSW) ("the Act"), a payment claim must identify the construction work or related goods and services to which the progress payment relates. The breakdown of claim is essential to meeting this requirement.
Case Law Clarifications
Multiplex Constructions Pty Ltd v Luikens [2003]
Palmer J emphasised that a payment claim must be sufficiently detailed to enable the respondent to understand the basis of the claim. The court held that a mere lump sum without supporting calculations fails to meet the Act's requirements.
Southern Han Breakfast Point Pty Ltd v Lewence Construction Pty Ltd [2016]
The High Court reinforced that while technical precision isn't required, the claim must contain sufficient information for the respondent to understand what work is being claimed for and to calculate or verify the claimed amount in order to prepare a meaningful payment schedule.
Consequences of Non-Compliance
- The payment claim being declared invalid.
- Loss of statutory rights under the Act.
- Inability to pursue adjudication for the claimed amount.
- Potential costs orders against you if court proceedings are commenced unsuccessfully.
3. Practical Guidance
Step-by-Step Instructions
- Start with Your Contract Structure: List all contract items, trade packages, and approved variations. Identify any milestone payments if applicable.
- Calculate Each Component: Clearly show the calculation for each line item (e.g., Quantity of work completed × Rate = Amount). For lump sum items, show the percentage complete.
- Apply Contract Adjustments: Add approved variations and deduct retention if applicable. State whether GST is included or excluded as per the contract terms.
- Reconcile Previous Claims: Show the total value of work completed to date, deduct previous payments received, and calculate the current claim amount.
Where to Find This Information
- Contract rates: Schedule of rates or contract price breakdown.
- Quantities: Site diaries, progress reports, survey measurements.
- Variations: Written variation approvals, site instructions.
- Previous claims: Your payment claim register and accounts records.
Presentation Guidelines
Present your breakdown in a clear tabular format. Use consistent numbering that matches your contract documents. Group similar items logically and provide subtotals for major sections to improve clarity.
4. Common Mistakes and How to Avoid Them
Typical Errors
- Lump Sum Without Detail: Claiming a single large figure like "$150,000 for work completed" without breaking it down.
- Inconsistent Calculations: Mathematical errors or rounding inconsistencies that undermine the credibility of the claim.
- Missing Variation Details: Including amounts for variations without referencing approval documents or showing how the cost was calculated.
- Unclear Quantity Claims: Not showing how quantities were measured or derived, making it impossible for the respondent to verify.
Best Practices
- Use the same item numbers and descriptions as your contract.
- Show all calculations, even simple ones. Transparency is key.
- Include references to supporting documents (e.g., variation approval numbers, drawing references).
- Ensure the breakdown is mathematically consistent with previous claims.
- Have the calculations independently checked by a colleague before submission.
5. Risks of Not Including This Information
| Risk Category | Description of Risk |
|---|---|
| Legal Risks | Your payment claim may be deemed invalid under the Act, meaning you cannot enforce it through adjudication or rely on statutory payment timeframes. |
| Financial Risks | Causes significant payment delays while clarifications are sought. Respondents may only pay parts of the claim they can verify, disrupting cash flow. |
| Dispute Risks | Inadequate breakdowns are a common trigger for payment disputes, leading to protracted negotiations and an increased likelihood of formal dispute resolution. |
| Strategic Disadvantages | In adjudication, a poor breakdown weakens your position, makes it difficult for an adjudicator to accept your claim, and allows respondents to raise validity challenges. |
| Contract Administration | Creates ongoing problems for reconciling final accounts, assessing variations, and can strain the commercial relationship with the client. |
6. Examples
Example 1: Trade Package Breakdown
Electrical Installation - First Floor
Base Contract Work:
- Light fittings: 45 units × $120 = $5,400
- Power outlets: 30 units × $85 = $2,550
- Cable runs: 450m × $12/m = $5,400
Subtotal: $13,350
Variations:
- Additional emergency lighting (VO-023): $2,200
- Relocated switchboard (SI-045): $1,850
Total This Claim: $17,400
Example 2: Percentage Complete Calculation
Structural Steel Package
Contract Value: $500,000
Work Complete to Date: 73%
Value Complete: $365,000
Less Previous Claims: ($285,000)
This Claim: $80,000
8. Frequently Asked Questions
Q: How much detail is legally required in the breakdown?
A: The breakdown must contain sufficient detail for the respondent to understand and verify your claim. While you don't need to provide every minor calculation, each significant component of work must be itemised with quantities and rates shown.
Q: What if some quantities are estimated?
A: Clearly mark any estimated quantities and provide the basis for your estimate (e.g., "based on preliminary drawings"). Include a note explaining why actual measurements weren't available and when they will be confirmed.
Q: Should I include retention in the breakdown?
A: Yes, it is best practice to show retention as a separate line item deduction after calculating the gross value of work completed. This maintains transparency about the full value of your work versus the net amount being claimed.
Q: How do I handle partially complete items?
A: Show the percentage complete and how you determined it (e.g., "Foundation: 60% complete based on 12 of 20 pads poured"). Include supporting evidence like photos or reports where possible to substantiate the claimed progress.
