Claims And Variations
Progress Claims Management and Variations for Construction Projects
How claims are prepared and supported, how variations are priced and approved, how retention comes back and what to do when a claim is disputed.
Progress claims management is the routine of turning work done on site into payment: measuring progress to the claim date, assembling the supporting documents, valuing variations, accounting for retention and serving the claim when the contract allows. Sami Strategy Co. runs this cycle for subcontractors and builders in Melbourne and remotely across Australia; this page explains each part in plain words.
Most payment problems trace back to one of four points: a claim without the evidence to support its value, a variation carried out before its price was agreed, retention that nobody tracked, or a disputed claim with no paper trail. Each is avoidable with a steady routine and a tidy record.
Victoria has security of payment legislation, the Building and Construction Industry Security of Payment Act 2002, which sets timeframes for serving payment claims and for responding to them. Law firm summaries report that major amendments commenced on 15 April 2026, so check the current version on legislation.vic.gov.au before relying on any timeframe.
What We Do
What does progress claims management cover?
A progress claim has four parts that must agree: the value of work completed to the claim date, approved and pending variations, retention deducted or released, and amounts previously certified and paid. We build each claim so those numbers reconcile to the contract sum and to the last claim, with the evidence attached so the assessor can approve it first time.
Variations follow their own track. When the scope changes we confirm the instruction in writing, price the change from your tender rates or from first principles, submit it for approval and carry it into the claim once agreed. Retention is tracked from the first claim so the amounts held and the release dates are never in doubt. When a claim comes back short, we prepare the comparison and your reply.
- Measure work completed to the claim date against the contract breakdown or schedule of rates
- Assemble the evidence: marked-up drawings, dated photos, delivery dockets, signed day sheets and approved variation records
- Track pending, approved and rejected variations so the claim only carries what can be supported
- Calculate retention on each claim and diarise its release dates
- Prepare the final claim, the retention release claim and the defects period paperwork
Who This Is For
Who needs support with construction payment claims?
Anyone paid in stages under a construction contract, or paying others in stages, has a claims cycle to manage.
Subcontractors
A subcontractor's cash flow depends on each claim being accepted at its full value. We measure your progress, assemble the evidence, price your variations and follow up the schedule or certificate when it is late, so the amount paid matches the work done.
Learn moreBuilders
Builders and head contractors receive claims from every trade and issue their own claim upstream. We assess incoming claims against each subcontract, check the variations behind them and roll the certified amounts into your claim to the client so both sides of the ledger match.
Learn moreHow It Works
How does the claims cycle run from site to payment?
The same sequence repeats each claim period, which keeps the record reliable.
Contract set-up
We read the payment, variation, retention and notice clauses and note every date and form requirement. The claim template, variation register and retention tracker are built from those clauses.
Measure, value and evidence
Before the claim date we measure the work completed with your site team, value the approved variations and list pending ones separately. Each line is then matched to a document: a marked-up drawing, a photo, a docket, a signed day sheet or an approved variation.
Serve and track
The claim is served in the form and by the method the contract requires, on the date it allows. We diarise the response period from the contract and the current legislation and follow up as soon as a schedule or certificate is due.
Reconcile the response
When the schedule or certificate arrives we compare it line by line with the claim. Agreed amounts are recorded, differences are listed with the reason given, and we draft your reply where the reason does not hold up.
Close out
At practical completion we prepare the final claim, confirm the retention held and its release dates, and keep the file ready for the defects liability period and the last release.
What You Get
What do you receive for claims and variation management in construction?
Each deliverable is a working document you keep and can hand to an accountant, a lawyer or a new administrator.
Claim-ready submission
A claim built on the contract breakdown with its measurement, variation schedule, retention calculation and evidence bundled together, ready for your sign-off before it is served.
Variation file
For every variation, the instruction or site record, the price build-up, the submission date, the response and the agreed value, so each change's history sits in one place.
Retention and payment reconciliation
A running statement of amounts claimed, certified, paid and held, with the retention release dates taken from your contract and updated after every response.
Dispute position summary
When a claim is cut or rejected, a short summary of what was claimed, what was allowed, the reasons given and the options the contract gives you, so you can decide how to respond.
Scope And Cost
What affects the cost of claims and variation management?
The scope is agreed before the first claim, and the effort follows the size and tempo of the contract.
- How many claim periods remain and how many trades or packages each claim covers
- The measurement required, from a percentage complete to a detailed schedule of rates
- The expected number of variations and whether tender rates cover them
- Whether we prepare your claims, assess claims from others, or both
- The assessor's evidence standard, such as photos, dockets and signed records on every line
- The state of the records if we join a project already under way
Why Sami Strategy
Why have Sami Strategy run your claims and variations?
We read the breakdown like the estimator who priced it
Our estimating and tendering work means we know how a contract breakdown and schedule of rates are built. A variation priced from the same rates and quantities is easier for the other side to check and approve.
One record, kept current
Every claim, variation, schedule and payment goes into registers that reconcile to each other. When a question comes up months later, the answer is in the file with its date and document.
Melbourne based, plain advice
Directors Sandra Seo and Mina Song run Sami Strategy Co. from Melbourne and support subcontractors and builders throughout Victoria, with remote consulting in other states. We explain each claim and response in plain terms and leave the commercial call with you.
Sandra and her Sami Strategy team are the professional Project Management resource for our projects. Very Highly recommended.
Questions
Frequently asked questions
What supporting documents does a progress claim in construction need?
Every line should be backed by a record: a marked-up drawing of the work completed, dated photos, delivery dockets, signed day sheets and the written instruction behind each variation. The claim should also show the contract sum, the amount claimed to date, the amount previously paid and the retention deducted. The contract may also call for a set form or a statutory declaration.
How are variations priced and approved on a construction project?
Most contracts set a method: contract or tender rates where they apply, agreed rates or quotes where they do not, and otherwise reasonable cost plus a margin. The price goes in with the instruction and a build-up of quantities, rates, labour and any time effect, and the other party approves, negotiates or rejects it in writing. Where work must proceed before the price is agreed, the written instruction and a daily record become the evidence.
Can a variation be claimed if the instruction was only verbal?
It depends on the contract, and many contracts make a written instruction a condition of payment for a change. Confirm a verbal direction in writing straight away, stating what was asked, by whom and when, and keep daily records until the price is agreed. Without that record the claim rests on memory, which is a weak position in a dispute.
How does retention release work at the end of a construction project?
Retention is money held back from each progress payment as security for the contractor's performance, and the contract says when it is returned. A common pattern is a release of part of it at practical completion and the balance once the defects liability period has ended and any defects are made good. The release is claimed like any other amount, so diarise the date and serve the claim when it arrives.
What is a defects liability period and how does it affect payment?
It is the period after practical completion during which the contractor must return and fix defects that appear, and its length is set by the contract. It affects payment because the final part of the retention is usually tied to its end, and unresolved defects can be raised as a reason to withhold that release. Keep the defects list in the same file as the claims.
What happens when a progress claim is disputed?
The paying party normally responds with a payment schedule or certificate stating the amount it will pay and the reasons for any difference. Compare the response with the claim line by line, separate measurement from variation disagreements and gather the evidence for each. Many differences are settled by correspondence once the records are on the table; otherwise the contract sets out dispute steps, and Victoria's security of payment legislation has its own process and timeframes, to be checked in the current Act.
What does Victoria's security of payment legislation mean for construction payment claims?
The Building and Construction Industry Security of Payment Act 2002 sets timeframes for serving payment claims and for the paying party to respond, alongside whatever the contract says. Law firm summaries report that major amendments commenced on 15 April 2026, so older guidance may be out of date. Read the current version on legislation.vic.gov.au or speak to a lawyer; we administer the contract and leave legal questions to lawyers.
