1. Field Name and Definition

The Work Period is the specific timeframe during which the construction work being claimed was performed or the related goods and services were supplied. This field identifies the chronological boundaries of the work that forms the basis of your payment claim.

This field appears on a Payment Claim to establish a clear temporal connection between the construction activities performed and the payment being sought. It provides a critical reference point for all parties to understand exactly which work is being claimed in the current payment application.

2. Legal Requirements

Relevant sections of the Building and Construction Industry Security of Payment Act 1999 NSW

While the Act does not explicitly mandate the inclusion of a "Work Period" field in a payment claim, it is directly connected to several critical provisions:

Case Law Clarification

Several cases have clarified requirements related to work periods:

• In Estate Property Holdings Pty Limited v. Barclay Mowlem Construction Limited [2004] NSWCA 393, the court established that some element of the claimed work must have been completed within the 12 months prior to the payment claim date for it to be valid.
• Bauen Constructions Pty Ltd v Sky General Services Pty Ltd & Anor [2012] NSWSC 1123 addressed issues related to timing of claims and established that the 12-month period runs from when physical work was last performed, not from the end of a defect liability period.

Consequences of Incorrectly Completing or Omitting this Field

Failing to properly specify the Work Period can have serious consequences:

• The payment claim may be deemed invalid if it cannot be established that the work was performed within the statutory time limits.
• It may be difficult to distinguish between current and previous claims, potentially leading to disputes about what work has already been paid for.
• Without a clear work period, respondents may argue they cannot properly assess the claim, potentially strengthening their position in payment disputes.

3. Practical Guidance

Step-by-step Instructions for Completing this Field

1. Identify the applicable time period: Review your site diaries, progress reports, and project records to determine the exact dates when the claimed work was performed.
2. Check the contract: Your construction contract may specify how work periods should be defined (e.g., calendar months, 4-week periods, or milestone-based).
3. Format the dates correctly: Express the Work Period clearly using the Day Month Year format (e.g., "1 June 2025 to 30 June 2025").
4. Ensure consistency: The Work Period should align with your reference date and the timing provisions in your contract.
5. Be specific: Avoid vague terminology like "recent works" or "ongoing works" - always provide exact dates.

Where to Find this Information

The information required to complete the Work Period field can be found in:

• Project programming documents
• Site diaries and daily logs
• Timesheets and labour records
• Delivery receipts for materials
• Meeting minutes documenting progress

4. Common Mistakes and How to Avoid Them

Typical Errors

• Overlapping work periods: Including days that were claimed in previous payment applications.
  Solution: Maintain a register of all payment claims and their respective work periods.
• Claiming for work outside the statutory timeframe: Making claims for work completed more than 12 months ago.
  Solution: Implement a tracking system to ensure timely claims.
• Vague or missing work periods: Failing to specify exact dates.
  Solution: Always include specific start and end dates for the work period.
• Misalignment with reference dates: The work period not aligning with contractual reference dates.
  Solution: Understand how your contract defines reference dates and ensure your work periods align.

Impact on Payment Claim Validity

Any of these errors can potentially render your payment claim invalid or significantly weaken your position in a dispute. Courts and adjudicators have consistently held that proper identification of when work was performed is an essential element of a valid payment claim.

7. Related Fields

The Work Period field directly relates to and impacts several other fields in the Payment Claim:

• Reference Date: The Work Period must correspond to a valid reference date as defined in your contract or by the Act.
• Description of Work: The construction work described should have been performed within the stated Work Period.
• Amount Claimed: Only work performed within the stated Work Period should be included in the claimed amount.
• Previous Claims: The Work Period should not overlap with periods covered by previous claims (unless you're re-claiming unpaid amounts, which should be clearly identified).
