How to Submit a Variation That Actually Gets Paid (and Won't Be Ignored)
1. The "Golden Rule": Notice is Everything
Most contracts (especially the heavy-duty ones like AS4000 or GC21) have strict Time Bars. If you don’t notify the client within the specified time frames, often as little as 2 business days - you may legally lose your right to claim for extra money.
The Trap: Thinking "I'll sort it out at the end of the month."
The Fix: Send a notice of variation the moment the scope changes. Even if you don’t have the final cost yet, get the notice in writing immediately. Be sure to check the requirements for notices under your construction contract.
2. Evidence: Records, Records, Records
A Head Contractor sitting in a comfortable office 50km away from site doesn't see the additional work that you’re dealing with.
Timestamped Photos: Take photos before, during, and after the extra work.
Site Diaries: Ensure your Site Supervisor records the exact hours, plant, and quantities of materials used for that specific variation.
Seek written direction from the client: Before proceeding request that the client confirms verbal instructions with written follow-up. If it’s not in writing, what’s to say anyone directed you to do the additional work?
3. The "Scope Gap" Strategy
Don't just say "Extra plumbing work." You need to contrast the New Work against the Original Scope of Works.
Pro Tip: Quote the specific drawing number or specification clause from the contract. Show the client exactly where the original scope ended and where this new requirement began. It makes it much harder for them to claim it was "already included."
4. Value the variation correctly
Most construction contracts will determine how Variations are valued. If not, to get paid fairly, your variation should include:
Direct Costs: Labour, materials, and equipment.
Indirect Costs: Site supervision and mobilisation.
Margin: a percentage for overheads and profit.
Delay Costs: If the variation pushed the schedule back, are you entitled to Delay costs?
5. Use the "Right" Language
Avoid being emotional or aggressive. Use "Contract Speak." Instead of saying "You're ripping us off," use:
"Under Clause [X] of our agreement..."
"This constitutes a direction to vary the works..."
"Please provide a written direction to proceed to ensure project continuity."
The Reality Check
If you are consistently fighting for variations, the problem might not be your work, it might be your Contract Admin processes. In today’s construction and building industry, a subcontracting business cannot be run on "she'll be right" handshakes. You need a system that captures variations as they happen, not when the bank account is empty.

Construction Contract Review in Australia: What It Is and Why It Matters
What is a construction contract in Australia?
In Australia, construction contracts are agreements between parties and are legally binding. Construction contracts identify the parties involved, defines each party’s rights and obligations, and allocates commercial risk between the parties.
Construction contracts commonly take the form of either standard forms of construction contract or bespoke construction contract. Selection of the form of construction contract is often determined by things such as the procurement route, risk allocation, pricing mechanism and corporate governance. Forms of construction contracts commonly used in the Australian building and construction industry, along with their common use are detailed in Table 1:
| Form of contract | Common use |
|---|---|
| Australian Standards contracts such as AS4000, AS2124 and AS4902 | Commercial projects |
| GC21 Contract | by the New South Wales (NSW) Government for projects over $1 million |
| HIA and Master Builders contracts | Residential projects |
| NEC4 | Recently adopted by Sydney Water |
| Bespoke | Complex projects or by tier one contractors labelled as ‘standard subcontracts’ for their subcontracts |
What is a construction contract review?
A construction contract review is a critical analysis of all sections of a construction contract and should include (but not limited to) a review of the items identified in Table 2:
| Section of Construction Contract | Reason for review |
|---|---|
| Formal instrument of agreement | To ensure that the parties to the contract are correct and whether the contract is to be executed as a deed or an agreement |
| The scope of works | The scope of works should be concise and unambiguous. It should highlight who does what, how they will do it, and when they will do it. |
| Programme | To ensure that the scope of works, and deliverables can be achieved by the dates in the programme. |
| Pricing documentation such as lump sum breakdown, bill of quantities or schedule of rates |
1. Check that rates align with what was quoted and agreed 2. descriptions align with the scope of work 3. pricing notes and application of rates is clear and unambiguous 4. the correct unit of measurement has been applied to each line item |
| General conditions and special conditions |
1. understand the rights and obligations of each party to the contract 2. understand the commercial risk exposure such as liquidated damages, completion requirements, securities, indemnities, warranties, payment terms, adjustments for time and / or cost, variations, extension of time and insurances |
| Annexures, schedules and reference documents | Annexures, schedules and reference documents can include things such as 1. deed of guarantees 2. deed of release 3. deed of novation 4. form of unconditional undertaking 5. form of warranty 6. management plans 7. client mandatory requirements Therefore it is essential to review these items of the construction contract to understand the commercial impacts that agreeing to these documents can have on your organisation |
Why complete a construction contract review in Australia?
A construction contract should capture the commercial deal between the parties - nothing more, nothing less.
A construction contract review ensures that:
The contract aligns with what has been priced
Risks are identified and understood
Your organisation is not accepting unpriced or unintended obligations
Failure to understand the construction contract can often leads to:
Disputes
Delays
Cash-flow impacts
Unrecoverable costs
All of which are likely to erode your organisations profit margin.
When should you perform a construction contract review?
Tender stage:
Completing a construction contract review during the tender stage is critical to commercial success.
At this stage, a review allows your organisation to understand:
Risk allocation
Scope, allowances, and exclusions
Programme and time obligations
Quality and compliance requirements
This knowledge enables informed estimating and pricing and facilitates meaningful negotiation of the contract between the parties.
Failure to review the contract at tender stage often results in contract compliance issues and disputes between the parties later in the project.
Pre execution (before signing):
Reviewing the contract prior to execution ensures that:
All agreed departures have been properly captured
Amendments have been incorporated into the for-execution version
At this stage, it is also prudent for a to prepare a rights and obligations register to support effective contract administration.
Project delivery:
Good project and contract management requires continual reference to the construction contract during project delivery.
The contract should be reviewed continually to understand each party’s rights and obligations and avoid disputes; however, it is recommended to review and always refer to the contract when dealing with:
Variations
Delays and extensions of time
Claims and disputes
Completion and close-out
The requirements for achieving completion should be defined in the construction contract and must be understood by all parties.
At completion, contracts often require the submission of a final payment claim and execution of a deed of release.
Failure to understand these obligations can result in unintended waivers of entitlement.
Who can review a construction contract?
Technically, anyone can review a construction contract. However, different team members in the construction industry review construction contracts from different perspectives as per Table 3:
| Reviewer | Perspective |
|---|---|
| Lawyer | Legal enforceability and risk |
| Project managers | Programme, operational delivery and quality |
| Quantity surveyors and commercial managers | Commercial and risk-management to understand entitlements to additional time and cost |
| Contracts administrators |
Compliance focused |
| Insurance brokers | To understand insured and uninsured risk |
For the best outcome, construction contract reviews should involve multiple stakeholders from your organisation, ensuring that risks are avoided, mitigated or understood from legal, operational and commercial perspective.

Why Your Organisation Should Engage a Contracts Manager
How Better Contract Management Protects Budgets, Compliance & Operational Outcomes
How Better Contract Management Protects Budgets & Operational Outcomes
Contracts are more than signed paperwork especially in New South Wales. Whether you’re in government, a tier 1 contractor, subcontractor, supplier or consultant, active contract management is essential. It helps protect budgets, ensures compliance with public procurement standards, and keeps programs running smoothly from start to finish.
This article explains why a Contracts Management professional adds value and reduces risk, not legal advice, just practical insight ensuring contractual compliance
What Contract Management Really Means in NSW
A Contracts Manager oversees and governs your organisation’s contractual relationships throughout the lifecycle of an agreement from pre-award through to contractual discharge.
In NSW, this includes:
Performing a comprehensive contract review and negotiating terms and conditions before signing the contract
Understanding each party’s rights and obligations
Monitoring performance against contract terms
Ensuring variations documented
Tracking deliverables, milestones, and payment triggers
Maintaining a clear audit trail for decisions
These tasks may seem administrative, but they are critical to ensure successful project outcomes.
Why Organisations Engage Contract Managers
1. Stronger Compliance with NSW Procurement Expectations
NSW public sector and Tier 1 Contractors operate in a high-scrutiny environment. Clear processes for contract variations, record keeping, and approvals reduce the risk of compliance issues.
Contract management professionals bring discipline and governance practices that align with internal audit and procurement frameworks.
2. Better Price, Scope & Variation Control
Unmanaged scope changes, undocumented variations and extension of time claims are a leading cause of disputes and budget pressure.
A Contracts Manager ensures:
Contractual notices for variations and extension of time claims are submitted to the client
Changes are authorised before work proceeds
Costs are tracked against budget
This brings transparency, ensures contract compliance and withstands audit.
3. Improved Performance Monitoring & Reporting
Keeping track of deliverables against agreed KPIs and milestones ensures contractual compliance.
A Contracts Manager ensures performance data is collected, analysed, and reported clearly - reducing ambiguity.
4. Accountability & Audit-Ready Records
Whether your organisation is audited internally or externally, having a tidy, accessible contract record is invaluable when responding to reviews or reporting requests.
When a Contracts Management Professional Makes Sense
Engage a Contracts Manager when:
You’re starting a major program with multiple contracts
Your team lacks specialist contracts administration capability
You’ve had audit findings or compliance concerns previously
You experience frequent change orders, variations or disputes with clients
Your contract has strict time bars
Rather than hiring permanent staff, a contractor can be project-aligned, cost-efficient, and immediately effective.
