A site stoppage does not erase your invoice

Start with the stoppage record

A site stoppage can feel like the whole job has been frozen, but your account balance does not freeze with it. If you have already completed work, that work still needs to be recorded clearly. The first mistake is relying on memory, because once days pass, the dates, crews and site conditions blur together.

Start a simple file for the stoppage itself. Note the date and time work stopped, who gave the instruction or who was on site, what areas were affected and what you saw. Photos, messages and delivery dockets matter here. The point is to prove what happened, not to build a courtroom novel.

Split finished work from delay costs

Then separate three buckets: work finished, work interrupted, and extra costs caused by the delay. Completed work is the easiest to claim. Interrupted work may need a careful record of labour, plant and materials left idle. Extra costs can include remobilisation, storage or travel, but only if you can tie them to the stoppage.

Do not mix those numbers together. A clean record helps you see what is already payable and what still needs support. Business.gov.au notes that construction work is often paid in stages and that each state and territory has security of payment laws for progress claims. That makes tidy job records commercially useful straight away. ([business.gov.au](https://business.gov.au/planning/industry-information/construction-industry?utm_source=openai))

Put the builder on notice in writing

Next, notify the builder in writing. Keep it short and factual: the site stoppage has delayed the job, you have recorded the dates and photos, and you want the status of payment for completed work confirmed. Do not rely on a phone call alone. Written notice creates a dated trail and reduces the chance of later disagreement.

If the stoppage was industrial action, the Fair Work Ombudsman says industrial action can be protected or unprotected, and employers may be able to stand employees down when they cannot be usefully employed for reasons outside the employer’s control, including industrial action. That does not tell you what your contract says, but it does show why the site record matters.

Serve the payment claim carefully

Once the paperwork is in order, serve a payment claim for the completed work if your contract and the relevant state or territory law allow it. Business.gov.au says security of payment laws help contractors recover payment for work they did, and in most states and territories a contractor can issue a payment claim with strict timeframes attached.

If the builder answers with delay or silence, keep the dispute narrow. Ask them to separate any claimed site stoppage issue from the amount already due for work done. You are not trying to solve the whole project in one email. You are trying to keep the payable part of the account visible and alive.

Track extra costs and keep moving

Track the extra costs as they happen. Write down lost time, idle plant, cancelled deliveries, extra supervision and any rework caused by the stoppage. Match each item to a date and an invoice or diary note. If the figures are rising, the file should show it clearly, not as a vague estimate at month end.

That record gives you options for the next conversation, whether the builder pays, negotiates, or pushes back.
